store a variable in session and echo that variable on a page wordpress
Sure! Here is a response:
To store a variable in session and echo that variable on a WordPress page, you can follow these steps:
Step 1: Start by adding the following code to your theme's functions.php file to start a session:
add_action('init', 'start_session');
function start_session() {
if( !session_id() ) {
session_start();
}
}
Step 2: Then store the variable in the session:
$_SESSION['my_variable'] = 'Your variable value';
Step 3: Finally, you can echo the variable on a page by adding this code where you want the variable to be displayed:
<?php echo $_SESSION['my_variable']; ?>
Make sure to use these steps in a child theme or a custom plugin to keep your changes separate from the theme's core files.
