In sometimes onchange = “document.formname.submit()” won’t submit the form, while it works on other html pages.

There is hidden truth of this problem is , there may be some other input having the name “submit”. This cause problem in IE and some other browsers. So rename the input field name from submit to any other name (In most case we use the name of submit button as “submit”).

It is a rare tip,  you may  face this someday !!!

As a solution, you can use wsdl2php converter tool. It is a command line tool, you can provide the wsdl url as an input and it generates a php file to make the soap client call. The tool may show some error during its conversion , but in the end, you will get a PHP code which executes.

Download wsdl2php from: http://www.urdalen.no/wsdl2php/

You need to add the below javascript in addition to the jquery js file.

<script type="text/javascript" src="path-to-file/jquery.fancybox.js"></script>

To create a link to open in fancybox, call the function fancybox. For example, if you have a link pointing an image <a href=”myimage.gif” id=”imglink” />

Call

<script>

$(”#imglink”).fancybox();

</script>

The window automatically resize with image. If you put title attribute, it shows the title below with the light window.

Instead of image, you can point a file. If you need to open that file in iframe, use class=“iframe”

Visit http://fancybox.net/howto for more usability.

To avoid this, follow the steps:

Include mootool js first
Include jquery js file second

Like this:

<script src=”javascript/mootools-release-1.11.js” type=”text/javascript”></script>
<script src=”javascript/jquery-1.3.2.min.js” type=”text/javascript”></script>

Then type:

<script>
jQuery.noConflict();
</script>

For mootool functions, continue with $ object and jQuery function , user jQuery object

For example , instead of $(”#div”), user jQuery(”#div”), another example is jQuery(”.common”).load(’myfile.php’)

Using firephp , you can debug your php code. Firephp is a firefox plugin which works on firebug console.

In our php life, we know we can use echo function to print or debug the value of a variable and we usually do that. But if there is any header function such as image manipulation, redirection etc, if you use echo or print either it leads into unwanted results or we get the common error, cannot modify header information headers already sent  !!!

The one solution for this is, writing the variable value into a log file and check the log file after execution. But the advantage of fire php is, you can log messages, or value of a variable and can see through firebug console.

For example:

<?php $fire_php->log(’Enter into function’); ?>

<?php $fire_php->log($result); ?>

You can also categorize your error as warning or error . eg:

<?php $fire_php->warn(’Variable value is not set’)?> or

<?php $fire_php->error(’No parameter passed’) ?>

For more go to: http://www.firephp.org/

What you have to do, is just add this js file below your html page which contains some mp3 href

<script type="text/javascript" src="http://mediaplayer.yahoo.com/js"></script>

You can see the demo here,if your browser supports flash

In a php project, if we get the requirement , we usually start design and database. But the data entry procedure is very hard. In this case PhpMyadmin is a good comfort. 

Here is another tool from phpguru.org , MySQL Table Editor. Using this library you can make your database table editable from your php code. 

You can  :

1. Select the table to be displayed
2. decide which column should be hidden
3. Whether a column should be editable or not
4. Add advanced searching option
5. Download the table as csv format
6. Add pagination
7. Set alias display name for your column

noDisplay('id');
$editor->noDisplay('password');
//the email column should not be editable
$editor->noEdit('email');
//set display name for column email and login
$editor->setDisplayNames(array('email'       => 'Email',
                              'login'     => 'Username'
                              ));
//sort order of first name
$editor->setDefaultOrderby('namefirst', 0);
//set which are the filed to be searchable
$editor->setConfig('searchableFields', array('namefirst', 'namelast', 'email'));
//can set the type of input field
$editor->setInputType('available', 'select');
//finally display the editor window
$editor->display();
?>

Basically using xajax “You can directly call php functions from your javascript code”

Xajax will do the rest. 

For example, if you are going to write a javascript function Capitalize which captilaze your textbox content when you press a button.

Here is the pure html/javascript code for that:

=============================================

<script>

function Capitalize()

{

      var t = document.getElementById(’cap’).value;

      document.getElementById(’update’).innerHTML = t.toUpperCase() ;

}

</script>

<input type=”text” id=”cap” name=”cap” />

<input type=”button” id=”capbutton” value=”Capitalize” onclick=”Capitalize()” />

<div id=”update”></div>

==============================================

Now see the difference when we use xajax, we can write this Capitalize function in php code and can call from javascript.

function Capitalize($value)

{

    $objResponse = new xajaxResponse();

    $objResponse->assign(”update”,”innerHTML”,strtoupper($value));

    return $objResponse;

}

and you can call from your button’s onclick function:

 onclick=”xajax_Capitalize(document.getElementById(’cap’).value)” 

Here the same functionality we moved from client to server. Thus the point is you can simply call all the functions you written in php (Server Side) from javascript code via onClick, onMouseOver or window.onLoad etc.

You can get the full source code of Capitalize example here:

Start jquery for manipulating html file and execute javascript just like sql queries.

Simply pointer the dom object with a $  and manipulate with different built in function.

For example 

$(”p.neat”).addClass(”ohmy”).show(”slow”);

Don’t need to write javascript inside each node. It is like prototyping. Insted of adding an onClick=”function()” inside the node, jquery define the onclick function from the top level. Your html code will be clean and tidy. If CSS removes all the styling bits, Jquery removes all the javascript bits from html.

You can remap every default action from an html object.

For example normally when you click a link  (<a> tag) it navigate you through the href value. But if you add the jquery code as below:

$(document).ready(function(){
   $("a").click(function(event){
     alert("Thanks for clicking!");
   });
 })

It adds a thanks alert for every click in links.

and if you add :

event.preventDefault();
It prevents the default action also.
You can go to JQuery homepage: http://jquery.com/
and can learn more about JQuery.
The intention of this post was not an explaination about jquery, but some addition website which develops addons based on jquery.
Those are:

I have developed more than 7 web projects using Symfony framework. Mobshare.in, Amvizone.com, Campaignmanger.in , Movieonline.in etc are some of the websites. But for the past 5 months my developement is in Codeigniter. It is very very lighter than Symfony and has almost all the features of Symfony. Both are MVC framework. But symfony has 4 layer while the latter has only two. Symfony uses modules (extra layer) for Controllers. But Codeigniter eleminates  that layer. It is similer to Ruby on Rails. 

Symfony uses naming convention to map controller and view. For example controller index need indexSuccess.php file as view or indexError.php as error. But in Codeigniter, we have to specify the view manually from the controller

$this->load->view(’myview.php’); 

Symfony has command line tool to develop all the model classes. One thing you have to do is specify the scheme.yml file. But in Codeigniter, you have to make model classes from the scratch. However a lot of database operation libraries are available with it to make the coding life easier. Since we have to load each libraries manually, Codeigniter gaurantee the speed of execution. (Autoloading option is there, but in most of the case we can eliminate unwanted libraries from autoloading – just like execute on the fly)

There is no built in ajax and javascript function in codeigniter. But you can add it as plugin. Like Symfony it also has cache management, logs, testing, helpers, url rules, documentator, scaffolding etc

Codeigniter has a simple folder hierachy that everybody can understand and very less learning curve than Symfony. 

Go through this link if you wanna know about all the features of codeigniter : http://codeigniter.com/user_guide/toc.html

I found another interesting comparison of these two in : http://www.devtrench.com/codeigniter-vs-symfony/
