In this post, we’ll be discussing how to use PHP sessions in WordPress using a simple code snippet. This can be useful for those who want to store user-specific data, such as cart information or form data, for use on multiple pages of their website.
The code snippet uses the init
action hook and a custom function named php_session
to start a PHP session on the frontend of your website.
<?php | |
add_action( 'init', 'php_session' ); | |
/** | |
* Start php session. | |
*/ | |
function php_session() { | |
if ( session_status() !== PHP_SESSION_ACTIVE ) { | |
session_start(); | |
} | |
} |
The init
action hook is used to execute the php_session
function at the beginning of the page load process, ensuring that the session is active before any other code is executed. The php_session
function uses the session_status()
function to check the current session status and the session_start()
function to start a new session if one is not already active.
It’s worth noting that starting a PHP session on the frontend of your website can have security implications, so it’s important to be careful when storing and handling user-specific data in a session. Additionally, it is important to make sure that the session is closed properly when it is no longer needed.
Summary:
By adding this code snippet to your functions.php file, you can easily start a PHP session on the frontend of your WordPress website. This can be useful for those who want to store user-specific data, such as cart information or form data, for use on multiple pages of their website.
