Hello.  I have a problem with this script, I want to make URL field to be a subject line or a Title field, but I don't know how to.  What happens is the script always checks if url is entered, and when it sees the url has spaces or does not contain .com it gives an error.  I know this is a simple fix, I'm not a PHP guy.  I tried removing variable from the scrip, but it ends up giving me page errors when I do.

 

Script is below.

 

<?php

if(preg_match('#' . basename(__FILE__) . '#', $_SERVER['PHP_SELF'])) { die('You are not allowed to call this page directly.'); }
