💡 Hint

Common Mistakes

Using different strings for the query var and the comparison value.

Checking the wrong query var name.

get_query_var('profile') returns 'profile' when on that endpoint, so both blanks use 'profile'.

Wordpress

<?php
function add_dashboard_endpoint() {
    add_rewrite_endpoint('[1]', EP_ROOT);
}
add_action('init', 'add_dashboard_endpoint');

function add_dashboard_query_vars($vars) {
    $vars[] = '[2]';
    return $vars;
}
add_filter('query_vars', 'add_dashboard_query_vars');
