wordpress Get ID from Page Name
Add to functions.php file:
function get_ID_by_page_name($page_name) {
global $wpdb;
$page_name_id = $wpdb->get_var("SELECT ID FROM $wpdb->posts WHERE post_name = '".$page_name."' AND post_type = 'page'");
return $page_name_id;
}
Now you can use this function in templates when you need an ID of a specific post/page and all you have is the name.
