Psycho Posted July 16, 2014 Share Posted July 16, 2014 The above is PHP code. But, that condition is invalid - you are missing the dollar sign at the beginning of the variable name: $title Plus, to do something "onclick" requires that you either submit the page and process the POST/GET data or you need to implement JavaScript to perform an AJAX request. I assume you want the latter. But, there's too much to try and tell you how to do this in a forum post. I would suggest you look up on how to implement JQuery's AJAX functionality.
