How to Modify PHP Session Variables Using Javascript

Utilizing Javascript to Modify PHP Session Variables

In some instances, you may encounter the need to manipulate PHP session variables from within Javascript. To achieve this, a combination of Javascript, HTML, and a PHP script can be employed.

Javascript Implementation

To initiate the process in Javascript, use the code:

jQuery('#div_session_write').load('session_write.php?session_name=new_value');

HTML Element

An HTML element is then added to serve as the trigger for activating the Javascript function:

<div id='div_session_write'> </div>

PHP Script ('session_write.php')

Finally, you'll need a PHP script to handle the session modification:

<code class="php"><?php
session_start();

if (isset($_GET['session_name'])) {$_SESSION['session_name'] = $_GET['session_name'];}
?></code>
