Hi I'm trying to use a session variable to pass a page ID from one page to another - so I know where I've come from.
I'm using the shortcode exec php plugin to insert the php
At the start of wp_config.php I've put session_start();
In the page I want to pass the page ID from I have:
$_SESSION['pageID'] = get_the_ID();
In the page I want to pass the page ID to I have:
echo "page id =" . $_SESSION['pageID'] . PHP_EOL;
but nothing is passed.
Please can you explain what I'm doing wrong or how best to pass the page ID between pages.
Thanks for any help
