GReat piece of code. Tested with a very very large category table and things are little slow. However for my shop that has 4 levels of categories this is absolutely perfect. Thanks

Hi, As I can see your plugin is communicating with server side (php script) by GET method. Any possibility to use POST method? It seems script is not passing value from input box if mode_rewrite is enabled. Anybody managed to use this autocomplete with some framework (cake, codeigniter) Thanx in advanced!

Hello!!! Great work!! Thanks a lot... but it isn't really JSON enable, JSON serialized data should be like [{prop1:"value1",prop2:"value2"}] now it expect [{"value1","value2"}]... Also in the getData() function you put inside the loop the assignation handlers for the events (hover, click...) so for every item back from the server, you do the same... Anyway...!!! THANKS AGAIN!!! My function.... function getData(text) { window.clearInterval(typingTimeout); if (text != oldText && (settings.minChars != null && text.length >= settings.minChars)) { clear(); if (settings.before == "function") { settings.before(textInput, text); } textInput.addClass('autocomplete-loading'); settings.parameters.text = text; $.getJSON(url, settings.parameters, function(data) { var items = ''; if (data) { $.each(data, function(index, item) { items += '

' + item.text.replace(new RegExp("(" + text + ")", "i"), "$1") + '

'; }); list.html(items); //on mouse hover over elements set selected class and on click set the selected value and close list list.show().children(). hover(function() { $(this).addClass("selected").siblings().removeClass("selected"); }, function() { $(this).removeClass("selected") }). click(function() { valueInput.val($(this).attr('value')); textInput.val($(this).text()); clear(); }); if (settings.after == "function") { settings.after(textInput, text); } } textInput.removeClass('autocomplete-loading'); }); oldText = text; } }

it is successful jquery gallery. But the description for the name is not right I think. It should be fading jquery instead of morphing. Because in the morphing process, the content of the image should warp. Not only the size of the image... Kind regards

Very great Plugin. I have been used this for some of my tasks. But today i faced problem. I need to do multiple select. Is it possible? I have try to put something like this:

4. Dip (next...)

5. Fault

I put multiple in DIPSELECT. And in javascript: $('#dipSelect').chainSelect('#faultSelect','modules/tab_content/index_controller.php', { usePost : true, after:function (target) { $(target).css("display","inline"); } }); I use POST to get array from the DIPSELECT. and in serverside: $dip = $_POST['_value']; My Question, i don't get any ARRAY value for $dip even i select more than one in DIPSELECT. How can we do this multiple by using this plugin?? Thanks and very great works!!!

Charles

2010-01-07 11:05:55

Hello All, Great plugin - I got it working in very short order. The only thing that hung me up was what to query in my PHP script that returned the JSON array. For those in the same boat: your script will work with two variables passed: "_name" - the ID (not class) of the field that was changed, and "_value" the value of the option that was selected. Since my PHP page will only serve requests for a specific field I did not use "_name". Now I have a question. I am a newbie to jQuery and Javascript so pardon what may be a stupid question: how can I assign a class to the options returned from the JSON array? Thanks, Charles

Hello, Thanks for this code, it's great, I have always wondered how to do this without using flash! One problem I am having though, is setting the changer intervals. I would like each slide to show for at least 5 seconds, but I am having trouble making that happen. I tried changing the javascript code in the beginning: var current_banner = 1; var total_banners = 0; var wait = 0; I tried changing these three values, but it doesn't seem to make a difference. Any help would be much appreciated. Thanks, Ezra

I am heppy to find this blog. I am a new(ish) PHP developer and have been experimenting for a while with emgines like Smarty and i honestly failed to see the point in them. The only good reason to learn it is in case you come across an application that has been entirely written in smarty. In my mind, it is no different than creating a template with empty modules and simply writing files in html/php that can be plugged anywhere into the template eg Header Header Header code1 code2 code3 Footer Footer Footer So all 3 pages are the same except the code that is surrounded by the template header and footer. It could take even a PHP expert a while to figure out what on earth smarty is doing and why it is doing it that way. For example, smarty that i have seen uses tables to position elements on a web page. That is something i did on my first website and now its a pain to maintain. Floating divs to me work much better.

This code will show all main categories. It will also include the main category in the link when a subcategory has been selected. and it will take care of the white space in the link when a category name has more then one word. category name is cars and trucks then the link will be: /cars-and-trucks/ if there is a subcategory in cars and trucks like new trucks then the link will be: /cars-and-trucks/new-trucks/ function generate_menu($parent) { $has_childs = false; global $menu_array; foreach($menu_array as $key => $value) { if ($value['parent'] == $parent) { if ($has_childs === false) { $has_childs = true; echo '

' . $value['name'] . ''; generate_menu($key); echo '

'; }

Here's a simple way to fix browser display problems with html entities. For example if you are indenting the combo box options with characters, we need to have the browser re-evaluate the html inside the options. Change the jQuery.fn.chainSelect function in jquery.chainedSelects.js as follows: var new_html = ''; for (i = 0; i < data.length; i++)//iterate over all options { for ( key in data[i] )//get key => value { //$(target).get(0).add(new Option(data[i][key],[key]), document.all ? i : null); new_html += ''; } } $(target).html(new_html);

Is there a reason, or is it just preference, that you passed a ref to $_GET to the sanitize function? I would probably have just returned a new array. Does it matter? Is one way more efficient or better, or not?

Nic

2009-08-23 21:59:36

Amnell I had the same issue this is what i get from firebug in firefox: "$("input#example").autocomplete is not a function" I was loading twice jquery.js and one after initating the autocomplete. Just remove the extra ref to jquery

I'm Confuse

matt

2009-07-27 16:45:39

Another note, I just realize there is a big problem with Guido's on select code, in that if its not click by the mouse (and instead the person uses the keyboard) it will not be fired. The solution is to just add: if (typeof settings.onClick == "function"){settings.onClick(valueInput.val(),textInput.val());} in the else if(e.which == 13)//enter } else section, putting it right about the clear worked well for me.

matt

2009-07-27 16:02:43

Pepe, you are correct, here is another fix for this plugin to make it disappear when focus is lost on the inputbox simply add the line: textInput.blur(function(e) {if(jQuery('.autocomplete:has(.selected)').length == 0){clear();} }) after the click (~line 94) seems to fix it

Kevin

2009-07-29 12:26:02

Hi, Nice script, but is it possible to return the

etc etc instead of echoing it directly in the function? Please give some info on this!

kevin

2009-07-29 16:23:15

Hi, here is a little mod I made to the script. For those you might be interested.. function generate_menu($parent){ $output = ''; // We will use this instead of echoing values straight into our function $has_childs = false; global $show_menu; foreach($show_menu as $key => $value){ if($value['parent_id'] == $parent){ if($has_childs === false){ $has_childs = true; } if($value['parent_id'] == '0'){ $output .= '

'; $output .= '

'.$value['title'].'

'; $output .= '

'.$value['title'].''; } $output .= generate_menu($key); $output .= '

'; $output .='

'; } return $output; } Also, this one will make your category name a Normal text instead of a link.. What i also did is add some fields in the Mysql Table and store my CSS class and ID, then pass them into the array and put then as variables in my HTML elements..

Milo

2009-07-30 06:07:32

another addition: put this in css: .strength-1 { width:250px; background:#cccccc; } put this in html if (password.length < 1) score--; desc[-1] = "Password not entered";

Pepe

2009-07-22 08:24:34

If the drop down list fills and you click off the field (focus on field blurs) the drop down list remains (needs to go away).

2009-07-20 01:29:44

can you give an example when using the defaultValue? Thanks.

matt

2009-07-15 15:34:08

Thanks for the great plugin, and thanks Guido, i needed something on the click event as well. also, if the exact position of the textbox that the autocomplete is on changes before the autocomplete is used, the list will sill show up where it should have been before the change. My solution was to add: list = valueInput.next().css({top: textInput.offset().top + textInput.outerHeight(), left: textInput.offset().left, width: textInput.width()}); between the list.html(items); and the list.show().children(). don't know if thats the best solution, but it seems to be working for me.

Hy Barry, By "you need to select the rows inside the function instead of declaring the menu_array as a global" he means to remove global declaration of array from the function definition and pass it to the function as a argument.

This is a wonderful image gallery in jQuery. I like it. But i experienced a bug while testing it... in IE6, the size of the frame dosn't work perfect. (I hate IE6 but lot of people are using it) Another thing: This gallery needs loading function.. shows the visitor a loading bar or something let to wait for image to load. Needed in previous and next images. When you click on the next button or another image, the previous one stays till the next is loaded. I think this should be fixed. Thanks

Z

2009-06-29 09:07:33

Hello, This solution dosn't work, if you want to send to save the datas with ajax. I think, this is better: textInput.after('').attr("id", textInput.attr("name") + "_text").attr("name", textInput.attr("name") + "_text");

what these smarty idiots do not realize is, that you can seperate logic from design with php. i use templates, and my template language is what? yes, php. and i only use php in templates to present dynamic content. i have never seen such a useless, harming software and it scares me, that people are so stupid to use it.

Bouke

2009-06-11 19:56:03

I've been using SMARTY for years and I must say that it makes web development much easier (and cleaner). I do agree that the templating language is a bit looser than it should be. But isn't php itself guilty of that as well? But if you stick to the SMARTY basics (variables, loops, conditionals, includes) it's really smooth. It reminds me a lot of Perl's HTML::TEMPLATE. I've also used the templating solution that CAKEPHP adopts and I've found that it provides too much abstraction. And still, it litters your template with PHP tags. Simple operations are often difficult and the learning curve is much higher than that of using SMARTY. SMARTY is also great to use when working with JQuery or even creating XML files. If used correctly, SMARTY is successful in truly separating business logic from display logic. I'm actually a bit surprised by the comments here. Hey, but whatever works for you...

I dislike your idea: is is not css, people must learn new syntax: "if:($price > 300 )//conditions" and if to parse html, then why not xslt? it's at least standartised. And time does not matter here if to use caching.

Franck

2009-05-17 15:14:35

Well i used smarty 2 years but finally back to php templates itself. Smarty was pleasant and easy to work with but i come to the conclusion that it's only adding another unnecessary layer. I think Smarty is great for someone who doesn't have MVC programming habbit but want to seperate business logic from template. But when you are able to write websites with MVC pattern or with the help of a framework, Smarty will not be the best solution. A simple registry class can help you to achieve good code separation for small / medium website. Ex: registry.php


vars[$name] = $value;
    }  

    public function __get($name)
    {
        if(isset($this->vars[$name])) return $this->vars[$name];
        else return null;
    }
}
?>

logic.php


$tpl = new registry();

//do logic stuff...

//assign tpl vars

$tpl->pageTitle = 'my page title blabla';
$tpl->datas = array('x','y','z');

template.php



 pageTitle; ?>

`datas as $data) { echo $data.' '; } ?>`

I found it was very diffcicutl to use without the mouse.. tabbing would pass to the next field and leave the suggestion open i added this line if (e.which == 9) clear(); at the end of this code //set selected item and input values textInput.val( list.children().removeClass('selected').eq(selected).addClass('selected').text() ); valueInput.val( list.children().eq(selected).attr('value') ); now it works just as we are used to, just like the browser autocomplete (wich I defeated with textInput.attr('autocomplete','off');

Help with Smarty Code

2009-04-10 13:10:55

I do hope you can help me with this. How exactly can you break each word on each title with comma? Is this possible by adding a code? I know you can break series of titles by adding {cycle values=", , , , ,"}. What about on a single title but would like to break each word in it with a comma. Appreciate any response from you either on this post or via email. Thanks.

FSan (and most others): Use this : http://blog.kotowicz.net/2009/03/jquery-optiontree-demo.html Chain boxes as many times you like. No Ajax, you prepare the date beforehand. Although 4 clicks for the user to get to what he/she needs? Consider a nested pulldown menu.

I think it'd be neat if the size of the image fading out, was slowly morphed to fit the size of the image fading in. Of course there'd be distortion, but since it's fading out, it might look cool.

This is a ridiculous jquery-plugin. Using ajax for this purpose is silly unless the amount of data is large, and in that case another presentational approach with less clicks would be preferred. This should at a minimum be solved without any serverside integration, and with cached data created at point of data modification. The complexness in this project is totally useless, and only creates trouble. Added to my extensive list of useless, bad written jquery-plugins.

The Smarty way is truly a good way - if you need it. And most projects do need it, even if they know/realize it or not. When to use smarty (or other template engines) : - When designers need access to your templates || - When the programmer needs to be forced into good coding practices - especially separating business logic from presentation logic. This forcing is required on 95% of php-developers. When you can skip smarty and use only php: - No designers (by good start realizing you need theese) && - The programmer understands the separation issue well enough to well..eh... SEPARATE! (the remaining 5% of php-developers) I'm myself one amongst those 5%, but I still use smarty. Partially because of the habit, partially because of the potential that a smarty-schooled designer might find its way into the employee despite of the firms incompetent leadership and partially because in any php-development-firm, there is most likely 1 or more developers not amongst the 5%, and they need to be forced. Theese are usually the high degree advanced programmers, switching from c++ or java to our "ridiculous" little language. Theese are the ones that constantly complain about loose typing, the lack of namespaces, and the need to bother themselves' busy minds with the lowbie presentational layer called html. Theese are the ones that create themselves a function to write a BR. Theese are the ones that think KISS is just a rock band, and spend a ridiculous amount of time trying to fit everything into a service-based system, where they cant rest before the singelton-pattern is in place and where everything is XML (needed or not, smart or not). Theese are the ones using a horrible amount of time programming in their hyper-advanced system just to make a mediocre guestbook (ofc it is very safe now...). Theese are the ones with knowledge of about 2% of the built-in php functions, utilizing substr, strpos, str_replace, if and else to proposterous, idiotic levels. Theese are the ones running your company bankrupt because of efficiency troubles. Theese are the ones putting the blame on php for "letting them" make the mistakes they do. "A real programming language wouldn't allow this programming mistake!" LEARN PHP BEFORE YOU WRITE, TAKE RESPONSABILITY FOR YOUR CODE! Frustration "out".

2009-03-04 19:55:47

To those who use smarty for big projects; good for you. Modifing design is a pain when its repeated/mixed in the logic. To those who use it for tiny projects; boo. There are more people involved than just the programmers and designers. The system admins have to setup up the engines and the compilers. For what? To make the programmers job easier. It just makes it difficult for the majority to take full advantage of PHP. Ive had to give up on great apps because they had dependence my server doesn't have. Straight code sometimes just works better. Smarty is NOT always the right answer. The programmer, designer and the admin relationship remind me of a law. The law of conservation of energy states that the total amount of energy in an isolated system remains constant. To get an app on the web the amount of energy remains constant. You can bet if the designer is using less the programmer and admin are using more. Smarty is flocked to now but there will be something the next generation flocks to and all our knowledge will depreciate.

You might want to take a look at TAL (or PHPTAL for the php implementation). From what I gather it comes pretty close to solving most (if not all) of the problems and demands you wrote about in both your posts on CHTS. If it doesn't solve your problem, I'm pretty sure it'll be a nice point of inspiration. (Although I might be missing some of your points... I've tried to read both your post attentionately, but I feel like I might be too tired right now to really absorb it properly...)

I have created extremely large estimation systems, various large shopping carts, job boards, etc. - so I'm no amateur to the PHP development environment, nor the ASP, VB, RealBasic, etc. Smarty Templates are NOT useful, and in fact get in the way and truly cause many issues amongst both the designers and the developers. They're confusing to just about everyone, completely unnecessary, and are time consuming to say the LEAST! Drew, you seem extremely proud of your work and from what it sounds like, it's SOOOO good that you don't even want people smelling it more or less actually seeing it (sheesh - gimme a break). Your comments are ridiculous and actually humorous. For anyone out there thinking of using Smarty Templates, DON'T - you'll find yourself with loss of time and a tremendous headache. I wish Drew the best in his amazing programming!!! Can't wait to smell his next project (wonder what that smells like...hint).

Sounds like your trying to do on the server side what it'd be trivial to do using jQuery on the client side. It supports css selection, DOM transforms, etc... If you gave it a JSON object for rendering in the view... it'd transform the page any way you wrote it to. You might want to look into server side JavaScript. If for no other reason than it seems to line up pretty well with what you're thinking. My 2 cents

By your script "aaaaaaaaaaaa" is a 'better' password. Better than what? Assigning points for length is great and all, but you need to be more dynamic when assigning points. Also, "Aaaaaaaaaaaa" should not be considered a 'medium' password. A descent brute force would have this one in a couple of hours tops. You should place a regex check in there that will deduct a point for repetition such as this. Last one is "123456789012" is also considered a 'medium' password. Numeric stringing (numbers in sequential order) is never a good idea.

Hello, I was curious, I'm trying to pass values to the chainSelect function to be passed as further parameters to the URI, so I could include things like other select option's values for hierarchical selective data. Beings that the call is formed off a php script, in this example, the possability of using it with database lookups, live, is also there. Say for example, I have a selection A, it has values that relate to selection B, and finally selection C which is based on the values of selection A + B together. How would you do something like this? If you would, and have ideas, please email me any ideas, as I am not too familiar with js itself, let alone JSON or AJAX or jQuery themselves, I've mostly been involved in PHP, Perl, etc.

Nice code, although it seems to suffer from problem that all php beautify scripts I've seen. php has for sometime had alternative syntax for control structures. I understand that these are the preferred syntax (although old school users aren't likely to switch to them). But it would be nice to beautify if...end, while...endwhile, for...endfor etc.

Hi, i have tried the example and looks great, but i think i am missing something. After choosing the first selection, i get a nice second selection, but then something wierd is happening. The third part of this combo, seems not to depend on my second choice? The option values are always numbered from 0 to X, so my third choice does not depend on my second? For example: // 1 = Demi if ( $_GET['_value'] == 1 ) { $array[] = array('1' => 'Demi 1'); $array[] = array('2' => 'Demi 2'); $array[] = array('3' => 'Demi 3'); $array[] = array('4' => 'Loop 1'); $array[] = array('5' => 'Loop 2'); $array[] = array('6' => '1140 systeem'); } else { $array[] = array('0' => '---'); } // 2 = WFI if($_GET['_value'] == 2 ) { $array[] = array('1' => 'Distiller 1'); $array[] = array('2' => 'Distiller 2'); $array[] = array('3' => 'Distiller 3'); $array[] = array('4' => 'Loop 1'); $array[] = array('5' => 'Loop 2'); $array[] = array('6' => '1150 systeem'); $array[] = array('7' => '1153 systeem'); } else { $array[] = array('0' => '---'); } and some more examples. So, when i choose the first or second option, i always get teh same third selection from: elseif ($_GET['_name'] == 'subdeel') { if ( $_GET['_value'] ==1 )//New York { $array[] = array('1' => 'New York'); $array[] = array('2' => 'Another city'); } else { $array[] = array('0' => '---'); } The generated source code is: Please help?

First of all great work. I have however been struggling to find a straightforward way to implement multiple instances of this script on the same page, for eg by passing two variables from the navigation buttons to the banner function: banner(nr,instance). Could you give me a hint how to make this work? I could loop the entire script in PHP for every instance and rename the functions for each - but it seems extremely inefficient....

You can read more here http://dev.opera.com/articles/view/javascript-support-in-opera-mini-4/ As an alternative you can submit form data on combobox onchange event and reload the entire page.

However, if the user submits the form and there are errors, when the page reloads, the states dropdown is not repopulated with the state they selected (assuming they selected one). How do I get that working? I'm using CodeIgniter, fwiw, so I'm using their validation lib to display form errors. Cheers, Bob

Even after getting a 4 year college degree in CS and having experience programming in PHP/MySQL, Java/JSP/Servlets, C#/.NET/MSSQL and even some C++, I feel like I'm just scratching the surface. So save your comments for impressing people that know nothing about programming so when people want to read intelligent discussion on various topics, we don't have to wade through your crap! Thanks so much!

Thanks for putting this page together...saved me some time in compiling 64-bit Apache 2.2.x. Wanted to pass on one note of interest: Setting --libdir=/usr/lib64 and compiling as a non-root user may cause problems during make install, as the install portion of the build will want to place some apr-related libraries in the directory that you set as libdir. So, if you are running an OS that already has files present that are related to apr via an already installed package, the make install will fail. In my case, I set --libdir=$APACHE_HOME/lib64 and the make install completed without a hitch. The apr-related libraries are placed in $APACHE_HOME/lib64 and the make install process also updates the envvars file to include a LD_LIBRARY_PATH declaration which includes the --libdir specified during configure, so the proper apr-related libraries will be used during runtime. Thanks again!

This is a pretty nice piece of work - with only a few beefs. 1) You should include the option to use spaces instead of tabs - some places require that kind of thing since editors sometimes do funky things, like include half-tabs or other strange quirks which make the code come out of alignment. I hacked this in manually in order to make it work. 2) the first line of a comment sometimes \"stacks\" with the line above it, giving the effect of: some_code(); # my comment becoming: some_code();# my comment

Discovered a possible error: I think that before setting $ADODB_FETCH_MODE in the constructor, you should import the global variable, i.e.: global $ADODB_FETCH_MODE; $ADODB_FETCH_MODE = ADODB_FETCH_ASSOC; Otherwise, it doesn't seem to be truly using ADODB_FETCH_ASSOC, but rather ADODB_FETCH_BOTH. Thanks again for the class.

Yes -- obviously to those who say 'seperating the php & html is not needed', obviously you need to go back to design school, because I would never let you come close to touching one of my projects. (not even smell it). Smarty is absolutely fantastic at splitting html from php. Sure, smarty has its own language but seriously... if you have troubles understanding smarty syntax, you should not be doing php either, because obviously you are an amateur at php (of the millions running around claiming to be 'good programmers'). Sure, the templates contain a bit of logic (loops, if statements and the like), however this should be kept straight to the idea of only being based off of display. Smarty has proven to be extremly useful to me over the years as business logic and presentation logic are truly separated. I don't care about the compiled templates and they are 'php again', because those are not what I edit. so funny.... to many amateur programmers running around... Its the one disadvantage to PHP. PHP is easy to become a novice in, however it takes a lot of time to be an expert in. PHP lets its programmers get away with too much... I mean honestly... not even initializing variables before use. That is basic programming stuff! If you don't do that at the minimum... well... its time to start leaving the amateur zone of PHP and brush up your skills!

Thanks for this useful script. I found there is a security hole. The first policy password length above 6 characters must be a mandatory policy. So the script may be changed as following: //if password bigger than 6 give 1 point if (password.length > 6) { score++; // another policies... if ... score++; if ... score++; ... } If not changed as above script then the passwords "1","Do","!","@" are evaluated as "Weak" and "1!", "Do!" are evaluated as "Better",... So I suggest the policy password length above 6 characters must be a mandatory policy. Thanks & regards, TrungTN

Is safer to put the default value instead of user input because PHP has some problems with UTF8 and the string comparison can be true but the string can be slightly different.

Wouldn't it be easier to do that last bit of code's switch statement thusly: switch ($_GET['bookCategory']) { case 'sf_books': case 'literature_books': $table = $_GET['bookCategory']; break; default: $table = 'cooking_books'; }

CodeAssembly

2008-05-21 12:22:45

Jakub Kulhan, this is just an example to show that query generation using user input is dangerous. It's not trying to be an example on how to design your database. @Konr Ness and @slink thanks for the tip, I forgot to put that break. @Wabbitseason, you can write your code any way you want, the important thing is not to slip any user input in the query.

Jakub Kulhan

2008-05-20 12:02:27

The last example (using user input as table name) is non-sens. With good database design you'll never get to this situation. For example suppose that we have these tables: books (id, name, type_id) and types (id, name). And here you can use bindable value, again, to choose type of book: SELECT * FROM books LEFT JOIN types ON books.type_id = types.id WHERE type.name = ? I think that it's more secure and for unknown type it won't return anything, which is more expectable.

Wabbitseason

2008-05-21 06:35:16

or ... switch ($_GET['bookCategory']) { case 'sf_books': case 'literature_books': $table = $_GET['bookCategory']; break; default: $table = 'cooking_books'; } $query = "SELECT * FROM $table"; or rather: $allowed = array('cooking_books', 'sf_books', 'literature_books'); if (@in_array($_GET['bookCategory'], $allowed)) { $table = $_GET['bookCategory']; } else { $table = current($allowed); } $query = "SELECT * FROM $table";

slink

2008-05-21 05:45:39

Probably you missed a "break" in case 'literature_books'.

Konr Ness

2008-05-21 10:59:07

That last bit of code with the switch statement has bug. You missed the break; statement after the 'literature_books' case. Without it, $table will be 'cooking_books' even if 'literature_books' was specified.

Hi I have a JSP page which has 6 combo boxes.When i select a value in the first combo the other 5 will filter with values which is done using AJAX. Now the problem is if the value i selected in the first combo has a size say 50 the screen looks very bad with scroll bars on both sides....All the combos size varies according to the value selected in first one.... Can anyone give an idea to have all the combo boxes sizes fixed irrespective of how the AJAX fires.

what about the new Zend Studio for Eclipse? It has an extensive code formatter built-in that you can configure to have every detail match your coding guidelines. Then, you can export those settings and have other people in your team import it. The formatting while working on a file is then only a single keyboard shortcut away. Sure, it costs money, but Zend Studio (for Eclipse) has been worth a lot of money for ages in my humble opinion. It supports development in PHP in so many useful ways that it's worth its price.

The argument that "Smarty separates PHP from HTML files" is extremely absurd and ridiculous. What Smarty does is REPLACE the PHP in HTML files with it's own syntax which mimics PHP's, so the problem remains. Same crap, different smell. So instead of designers learning PHP, they have to learn Smarty which is only marginally simpler (notice: SIMPLER and NOT EASIER). Separation of application logic from view can be achieved by various OTHER means far better than Smarty, such as MVC implementation or a better, cleaner, faster, templating engine. And what most people fail to realize is that whatever Smarty does, you can do with PHP exactly the same way. I invite you to search the web for the Savant templating engine. It's probably the prime example the ideal templating engine. Simple, fast, unobtrusive, and uses PHP native syntax to achieve all that Smarty can do, and more, with less resources.

First - thanks for the tutorial. Mauro, I had the same problem (worked on one server but only first row shows on a different server). Can you explain what you mean by selecting the rows inside the function instead of declaring the menu_array as global? Thanks.

MacGoerk

2008-05-01 14:22:23
Actually i think this has something to do with the use of a global var. If you change the function to generate_menu($parent, $menu_array) { remove the line "global $menu_array;" change the inner recursive call to generate_menu($key, $menu_array) and the initial call to the recursive function to generate_menu(0, $menu_array) where $menu_array is your mysql result set it will work! As php SHOULD make use of pointers and call_by_reference, this will indeed result in a slightly higher memory usage. If it isn't this is just ... going to be exponential large if you have a deeply nested structure. However I'll try this way :) Also, change the mysqli_whatever calls to mysql_whatever, as mysqli is deprecated. HTH Mac

Ok, I have been following this and have had a couple of issues, I stripped down my production environment to the bare essentials and ran my scripts in FF and IE7. I had no problems with FF and Firebug helped immensely. IE would not play ball, even though I had tried glenn's code (which incidentally precludes FF). I have been doing a bit of digging around and looked at other jQuery options for modifying the select list. The following line has been verified on IE7 and Firefox 2 and I have used it in place of Glenn's solution. I would be interested to hear how this works in IE6. $(target).get(0).add(new Option(data[i][key],[key]),document.all ? 0 : null); This was found via an article on Dr Dobb's Journal (http://www.ddj.com/java/201000935?pgno=4) Kudos to the author!

What about deleting? No one ever shows about deleting. I'm not talking DELETE WHERE id = $id AND parent = $id I'm talking if theres a Parent with a Child(1) that has a child(2) that has a child(3). If you delete the main parent how would it go about deleting all the way up to child 3 as child 2 is it's parent and child 1 is child 2's parent and parent is the parent of child 1. Hope I didn't confuse anyone.

what is the most popualr way to make a password stronger

Dave

2008-05-01 14:22:23
The best way to determine password strength is to calculate the number of possible passwords based on the known parameters of the current password. For example, in order of increasing strength: 5 characters, all lower case = 26 ^ 5 = 11881376. 5 characters, mixed case = 52 ^ 5 = 130691232. 5 characters, mixed case, numbers and symbols = 110 ^ 5 = 16105100000 10 characters, all lower case = 26 ^ 10 = 141167095653376 15 characters, all lower case = 26 ^ 15 = 1677259342285725925376 As you can see, a 10 character password has many, many more possible permutations than a 5 character password, even if there are much fewer possible characters for each letter of the password. This is because the exponent of the equation has much more impact than the operand on the final result. The trouble is, if the attacker knows that you strictly enforce your password policy then all the policy does is to reduce the number of allowable permutations. For instance, in the 5 character password above, one character must be upper case, one must be lower case, one must be a symbol and one must be a number... the fifth can be any of them. This leaves the possible combinations at 26 x 26 x 10 x 48 x 110 = 35692800. To find the number of permutations we need to multiply that number by 5! which leaves us with 4283136000 which is around a quarter of 16105100000, the original number of possible passwords if the password policy is not enforced. With all of this in mind, a password strength tester should assume that if you only have lower case characters then the operand is 26. If you have upper case as well then the operand is 52. Numbers add 10 to the operand and symbols add 48. The length of the password becomes the exponent of the equation. If your company enforces a password policy, simply divide the resultant password strength by 4. Then all you have to do is hard-code some arbitrary values for "very weak" through "medium" to "very strong" as raw numbers of possible permutations. P.S. This algorithm is still a little naive in that it doesn't take dictionary words into account. Dictionary words and variations on dictionary words such as letter-number substitutions, letter-symbol substitutions and prepending and appending numbers to the word are still extremely common. All good password cracking tools will run through dictionary words and their variations before trying the more random permutations and hence these choices of password are inherently weak.

2008-03-21 13:46:36
It seems my previous posting didn't correctly arrive: This is the line you need to use to get results in IE: $(target).append("");
Replace all in the inner for loop with this line. Btw, I really like this implementation, the size of the plugin is also heaven and I'm a big fan of php/jquery combo. This was right up my alley and it's being used in a production site as wel speak. Thanks codeassembly. If you need some help with finetuning this let me know.

Hi, For those who have trouble getting this in IE6 to work: replace: //option = document.createElement("OPTION");//create a new option //option.value = key;//set option value //option.text = data[i][key]; //$(target).append(option); //insert the option into the select With : //insert the option into the select $(target).append(""); There is something up with passing the .text attribute to the way it's constructed here. for some reason it does't work in IE and I cant be bothered to find out how to access the dom there. I could tell in FF that it was working. For any cache issues perhaps you could also change the parameter line to this one: parameters = { '_id' : $(this).attr('id'), '_name' : $(this).attr('name'), '_value' : $(this).val() , 'rrand' : Math.random() }; As such it will not cache the request as some IE's don't even listen to the ajax global options. Hope this helps some people here. Glenn

Hey there... yep, I believe it's a ADODB bug. I traced the FetchRow() function to ADODB... but couldn't locate the cause. And yes, the query does return rows. My knowledge of MySQL statements fall in the "intermediate" region... so to avoid any problems while using them through PHP, I always make sure the statement is wholly functional by testing them out first through phpMyAdmin and SQLYog. There's nothing wrong with the statement itself.. anyway, I'll try with the latest ADODB release and get back to you if it works out... Thanks, m^e

Does your query return any rows ? The FetchRow() function is within ADODB so it can be an ADODB bug, try updating ADODB. Also try testing your query and see if it runs fine using phpmyadmin or another tool.

Got a question here for the author. Scenario --------- I'm using .htaccess to redirect all page requests to my script, which then parses the pretty URLs and loads the correct page. Now some of these pretty URLs are generated out of concatenating 2 different fields, i.e. a 6 digit ID and a content title. The statement goes like... ----------------------------------- SELECT CONCAT( id, '-', title_nicename ) AS content_title, list_date AS update_date FROM tbl_content, tbl_content_meta WHERE tbl_content.id = tbl_content_meta.id ORDER BY tbl_content.list_date DESC; ----------------------------------- As you can see, the concatenated result is return as a pseudo field named content_title, which isn't physically present in any of the tables. When I pass this statement to your sitemap class, I keep getting this error message: ----------------------------------- Fatal error: Call to a member function FetchRow() on a non-object in E:\\xampp\\htdocs\\site\\core\\classes\\sitemap\\sitemap.php on line 185 ----------------------------------- In contrast, generating sitemap off hard-coded field names presents no problem at all. So the reason must be that the sitemap class is running into some difficulties reading the value out of this dynamically generated field. Any ideas how to get this thing working? Thanks, m^e

as you have all said, the purpose of templating engines is to separate presentation code from logic.. the problem is, the example above combines logic with presentation.. you can really see how useful smarty can be if you actually follow the rules and use it as it was meant to be used.. for example, in your php code, lets call it example.php: $name = db->getName(); //whatever... //NOW we do our logic, which is determining the greeting to use if ($name == "Wilma") $greeting = "Welcome Ma'am."; else if ($name == "Fred") $greeting = "Welcome Sir."; //and then we assign our greeting $smarty->assign('greeting', $greeting); //finally we display the template $smarty->display('example.tpl'); so in our template file, along with all our html, we just need: {$greeting} that's it..! much easier for a third-party designer to avoid (and not destroy!) the smarty syntax is incredibly simple, you can learn to use the basic features in a day.. not to mention it provides many plugins that offer pagination (extremely useful) amonst many other things.. or you can write your own plugins of course.. MVC frameworks are a fine alternative but you can't really beat the simplicity and flexibility of smarty.. i also agree with hari and michael phipps - it is my opinion that any html combined with the php means your website is actually just webshite =)

How do I fix this?

This code is great. I'm using the one with CSS formatting, not the javascript expandable one. My problem is the category names are linked and I don't want them to be. I only want the subcategories to be linked. On this page, the example shows the categories as unlinked, but when I use the code, it makes my category names linked. Any ideas?

Hi again, I have changed the following plugin script line: $(target).append(option);//insert the option into the select with this other one $(target).append('');//insert the option into the select and now the script works also in IE. I hope this help somebody ;)

Hi Mauro, I have the same problem as Jason but I dont understand you explination. What does this mean "you need to select the rows inside the function instead of declaring the menu_array as a global."? What does that mean? Which part of the script must I edit? Can you please give us an example.

I got the same error too.. i.e. "Parse error: parse error, unexpected T_RETURN, expecting T_OLD_FUNCTION or T_FUNCTION or T_VAR or '}' in sitemap.inc on line 274". If you look into the code, you'll find a misplaced "return" statement right before the closing brace '}' of the class. Commenting this out will make it work. Most likely the author didn't attach a tested copy of the class here. After fixing the error above, I encountered a second one. The ping() function makes several calls to the file_get_contents() method, but on line 132, the same is written as contents() causing php to throw-up an error and halt. Changing that should help too. Moreover, the URLs http://submissions.ask.com/ping and http://search.yahooapis.com/SiteExplorerService/V1/ping throw 403 Forbidden errors. Most likely the ping addresses have changed / and or require some sort of a login now. It'd be wise to enclose this section in a try-catch block so as to not break your code. Cheers, m^e

Well, the main reason to use Smarty (as was stated many times above) - to separate application logic from presentation logic. Yeah, right, you can write: Welcome Sir. Welcome Ma'am. Welcome, whatever you are. But ussually there is a whole bunch of pure php code above that. As alternative you offer MVC frameworks. Well, are they better than template engines? Maybe, or maybe not. There is the same learning curve and many other problems. So, you can't deny the necesity of logic separation. And that's why Smarty is not bad.

This meter is quite flawed. For example, I closed my eyes while hovering my hands over the keyboard. I randomly typed a 30 character password into your test program. I made sure I drifted up to the number row a few times to ensure a good mix of letters and numbers. Your algorithm rated this random string as "medium". Yet when I added ONE upper case letter, it suddenly became "strong". In another test I MD5 hashed a short sentence. Your algorithm only reported "medium" security. Major flaws include giving only one point credit for >12 characters while giving the same credit for a single upper case letter. Not giving proportional credit for longer passwords. Surely a 30 character mixed numeric/text password is many times more secure than a 13 character mixed case password. Your algorithm rates both the same. Seems to me major improvements would include giving proportional credit to length. Perhaps a simple randomness test or a letter frequency test? John

have been using fedora for past year and a half or so. started with fedora core 4, then jumped directly to fedora 7 and now using fedora 8. as far as my experience goes, fedora core 4 was more stabler than fedora 7 and fedora 8. currently am using 64 bit version. even if these problems persist i am a strong supporter of fedora. the problems am facing now, when running "compiz" and a desktop clock with some added GUI effects, crashes even when kept idle for some minutes. this is one major problem am facing now with this 64 bit. felt 32 bit version is more stabler than 64 bit version positives better detection of hardware auto mounting of windows partitions works bit faster than fedora 7 all i hope is to have a very stable version of fedora which can run non-stop with all latest gui effects as well as working as a server. in other words i should be a rugged operating system which can withstand all heavy loads and yet perform without any hiccups. this is just a suggession, not a bug. it is a common problem. hope to see a better version of 64 bit thanks

This is an absolutely ridiculous argument for larger projects because with templating systems you can avoid a lot of code duplication by keeping PHP separate from the HTML files. It's obvious you've never worked on any PHP application which involves considerably more thought process than "Hello World". Even if you avoid "Smarty" or templating systems in general, you would still find yourself writing a simple templating library yourself to keep having to repeat code segments in PHP. And trust me, large chunks of PHP code in HTML can be as confusing as hell after a while.

Your meter still allows submitting by pressing enter. Even if you don't capture passwords, your ISP is likely monitoring your traffic and will capture them. You might want to block that.

Nice class but don't forego service side validation. Client side validation does make the UI better for the user. But savvy user can still monkey with input after processing with Javascript. Always do server side validation. Always.

There are two ways to avoid rainbow table cracking: 1. Don't allow your encrypted passwords to fall into the hands of your attackers. 2. Use really long passwords. If you are adding salt to passwords to increase their length, don't forget to make sure it's different salt for each password or an attacker will be able to crack all of your passwords as easily as cracking one of them. Salt is also a good idea in general so that any two people with the same password won't have the same encrypted version.

The problem is there is a DVD with all the hash codes for NT, 2000 and maybe even XP for all the 14 character alphanumeric passwords. Can't find it now. :( Ah! http://www.codinghorror.com/blog/archives/000949.html Of course, throwing in on special character (+, -, #) you defeat that rainbow password cracking. At least until somebody decides to take that 8.5 gigs and starting adding more to it fill a 320GB laptop drive or a 1TB desktop drive. Since I'm now rethinking my password strategy, I have yet to settle on something that I really like. I'm thinking about using md5 hashes generated on my old passwords with a salt. At least for my web passwords. I've already found out how much my current low priority password shows up in Google with the md5 hash AND base64 encoding. Login passwords are another issue. md5 hashes aren't so great when you can't cut and paste.

Matt

2007-11-26 07:31:25
Interesting article & example. I'd like to add a couple of thoughts, with respect to both the "password security" discussion, and the code shown in the example. As e's comment demonstrates, length is very important, and longer the better. Also, the randomness of a password (entropy) is also very important. The "words with sprinkled numbers" approach seems strong because of the length. However, where brute-force may be infeasible against them, a dictionary and/or rainbow table attack would likely make short work of such a password. http://grc.com/passwords is a good resource on generating long high-entropy passwords. You should also take a look at your markup. The example page is missing a doctype, and H tags can't be nested within a P. Besides, having a header inside a paragraph just doesn't make sense. It would also have been nice to see this implemented as unobtrusive javascript, without the inline onkeyup call and and empty div tag. I hope you don't take this as harsh. It is meant to be constructive criticism. A UI feature like this is a good way to help users use stronger passwords, and this demo is pretty slick. With just a bit more work, it'll be worthy of the attention it seems to be getting on del.icio.us. You also might want to check your spelling of "meter" in the example code ;-)

This is fun! Is there any way of making this captcha accessible to those who have trouble seeing the pictures?

Avend

2007-11-15 21:34:39
Sure, this is a neat idea.. The only problem is that the picture samples you are using are repetitive: it would only take a few dozen manual refreshes to download all the images, sort them into the respective dog or cat category, and use that for making a bot. The bot could just compare file sizes (I think all these images have slightly different sizes), or perhaps an MD5 hash of them. A more robust solution I believe would be to perhaps generate a new image, placing N pictures of cats and dogs in the picture randomly, sending that to the client, then asking how many of each one there are. Of course, this number would probably be less than 10, so even with that you could send enough junk to eventually get some through.

Hi, Good article, but I have some suggestions. 6 letters is not a strong password. 6 letter passwords can be cracked almost instantly. I would suggest at least 8 characters. Also, your math is wrong. Using both cases is better than doubling. Consider a 6 character password only using lowercase. That's 26^6 = 308 915 776 possabilities. Using both cases however, is 52^6 = 19 770 609 664. The difference between these is a factor of 64. So for an n character password, using both cases increases cracking time by 2^n, not 2. Cheers

The mirror list should work again. A hardware failed in the Fedora data center but has been replaced now. For the bugs, have you actually filed any bug reports instead of just hoping they would be aware of it and fixing it all by themselves? It would be useful to participate and file good bug reports on problems you find. Helps others keep track of the issues too.

i agree with most of your points, even though i don't like your coding-guidelines. but that's a very subjectiv point of view ;-). however: in projects where you will not only have php code but javascript, perl, shell, whatever else phpdoc might not be the best solution, because i think the source-code documentation should look the same across all languages. i've tried several solutions for this and are now using robodoc, which i like very much. it won't analyse your source-code and therefore most time it's a lot more to write to document your code. on the other hand you have unified documentation for all your source-files - and i mean really all: you can even write documentation for your configuration-files for example.

I encountered a mailcious cracker on one of our servers, apparently it originated in Germany. How it got into our server is still a mystery. The cracker had a complete english dictionary list and tried to break into MS-SQL Server trying root, sa and admin and every word with numeric preamble and postamble. Brute force isn't hard to employ. We use a Dr. Seuss book and take 2 words from different pages and sprinkle numbers but no scheme is "uncrackable", or that's what we should assume.

Rafael Cortes

2007-11-05 09:25:17
Be carefull with the letter substituion alone, since most brute-force dictionaries already include words with the most common substitutions. i.e. P@ssw0rd will show as a strong password, but it exists in most dictionaries, so does $tr0ngP4$$w0rd (StrongPassword) and Sys@dm1n... While P@ssw0rd and Sys@dm1n shows in this script as Strong, $tr0ngP4$$w0rd shows as strongest, they will not sustain a dictionary attack which usually gets done before or during the brute force attack. Try to use word combinations such as W0rd1ng-4-G33k$ (Wording-for-Geeks), or backward words like ys@3t0N$I$ihT (ThisIsNotEasy).

Cute, but not particularly accurate, "P@ssw0rd" isn't really a "strong" password. Anything that http://www.openwall.com/john/ can crack in under 10 seconds counts as "very weak". Modern tools are quite quick at anticipating simple number/letter substitution and other "leet speak" tactics. Neat Javascript demo though - to do better you'd need to jump up the complexity significantly and use ajax running serverside dictionary attacks against the suggested password... cheers, big

Thanks for your answer, I believe I got the file location issues covered. I did test with all the files in the same directory on my local web server, just in case, I re-downloaded the files and tested again both on my local server and on my hosting. I tried with MS Explorer 6.0 SP2, Firfox 2.0.0.7 and Safari 2.02 for win, on a Win XP SP2 machine, the results are identical on all browsers. You can see what I mean at this address: http://www.masterkey.com.mx/validate.php I am still wondering why the html form name is not returned to the script, although there is a lot in it so at least it is partially working. Thanks in advance, Best Regards, Ra

You must put the files from this example in your "Document root" folder of your web server. I think the problem is that "validate.js" is not included in your html file, check the path of "validate.js". Also you didn't specify what browser you used, I only tested this example on Firefox and Internet Explorer.

Well this looks exactly what I need to verify inouto on my Web Site. Looks nice and clean. Unfortunatelly it does not work (at least for me), Am I doing something wrong? I know, stupid things take a long time... For some reason the "validate.js" is not producing the full code. 1) the desired script second line is missing: "function validateuser_registration(formname) {" so initially the broser marks an error "error: return statement outside function" becasue the function was not called. 2) Then the second fucntions wich apparently most to get the "Formname" is not geting it. 3) Sadly even I fill manually those gaps manually, the validation starts to work, but when the form is correctly filled, I does not call the exit function, but shows the form again, with the data initially placed on it before all the validations clear... I am sorry but I do not know any JS, so I ca not help. Here it is what I get from the JS function: Would love to have it working! Thanks in advance and keep doing this nice work. Regards, Raul S.

There is indeed no purpose to use any template system in php. PHP itself is a template language, for example you can write the code above like this: <?php if($name == 'Fred'): ?> Welcome Sir. <?php elseif: ?> Welcome Ma'am. <?php else: ?> Welcome, whatever you are. <?php endif; ?> Remember that PHP also has an alternative syntax(so you can dismiss those curly brackets ) if: //block endif; foreach($items as $k=>$v): //block endforeach; and the list goes on(for/switch/do/while ...) PHP itself is a fully fledged template language.

Hi Michael, if your templates are not made by a designer, but by someone with php knowledge, I don't see the purpose of using smarty. I think that a designer's job is to make the template in psd or other graphics format, and the front end programmer should make the html + css from that template and finally a php programmer should include the necessary php code to the template. I think this approach is the best, because everybody does what he is good at. I think is a very good idea to dump smarty, because there are no advantages in using it. You can try a template system based on php like phpsavant or you can try a full featured mvc framework, the advantage of mvc is that it keeps your code really organized, keeping your business logic separated from your presentation logic.

I'm a long time user of Smarty Templates, but I've gotta say you raise some really good points. Why do I use Smarty? To separate business logic from presentation logic. It used to be so designers could work with me, but I end up having to create the template myself anyway because web designers don't understand templates. I don't like having any HTML inside my PHP code. Even though, unless you enforce it, Smarty still allows PHP code in templates - and one project I worked on I found another developer just writing PHP business logic straight into the Template Pages... What's the point? With the way I use Smarty, there's really no reason for me not to use plain old PHP instead. In some cases I've used some pretty complicated template instructions to achieve something that would be much simpler to write in PHP. I have considered dumping smarty in the past. Maybe it's time I actually tried working without smarty on one of my sites?

I checked the example from your web server and I noticed that variables inside the heredoc from formvalidator class, are not parsed, it seems that there is a problem with new line characters between operating systems http://www.php.net/manual/en/language.types.string.php. I'm using linux, I guess you are running windows for your web server, so the new line character is not the same and the heredoc does not parse correctly. I replaced the heredoc with a double quoted string so now it should work on windows also. You can download the new files and try it. Thanks for the bug report.
