ed.windowManager.open({
file : url + '/shortcode_generator_popup.php',
I would like to move this file one folder above the current one that it's in. I'm wondering how I can rewrite this so that is points to the folder above. I've tried: file : url + '../shortcode_generator_popup.php' but of course it only turns into: /includes/js../shortcode_generator_popup.php
Thanks for any help!
