Question

I tried storing the REQUEST_URI in a session with the code below. I need to store the very first REQUEST_URI when a visitor lands on a page on our site and not have it overwritten when they begin browsing pages. This isn’t working as I browse the site i’m seeing a new URI displayed by the echo.

session_start();
if ( !isset( $_SESSION['theuri'] ) ) {
    if ( !empty( $_SERVER['REQUEST_URI'] ) ) {
        $_SESSION['theuri'] = $_SERVER['REQUEST_URI'];
    }
}

echo $_SESSION['theuri'];

I found this article which said to add this code to my functions.php and now the code in my footer is working fine.

add_action('init', 'myStartSession', 1);
add_action('wp_logout', 'myEndSession');
add_action('wp_login', 'myEndSession');

function myStartSession() {
    if(!session_id()) {
        session_start();
    }
}

function myEndSession() {
    session_destroy ();
}
