The Super Expensive Solution The solution here is this function: $post_id = url_to_postid( $url ); The problem is that this is a very slow function that’s expensive to call. If you call this when displaying … Read more

In the iframe function myTab_save_frame() { global $redir_tab; $redir_tab = ‘mytab’; media_upload_header(); ?> <button>Test Trigger</button> <script> var switchAndReload = function() { // get wp outside iframe var wp = … Read more
