Yes, your right, it's working
I see what the error is now.
My external database connection file had extra include files that were modifying the $_POST data. I rewrote a very simple database connection and everything is working just fine now.
So that solves it...
Sample php connection I used, instead of the complicated external database connection.
$dbhost = 'localhost';
$dbuser = 'xxxxxxx';
$dbpass = 'xxxxxxxxxxx';
$conn = mysql_connect($dbhost, $dbuser, $dbpass) or die ('Error connecting to mysql');
$dbname = 'wordpress';
Thanks to aamonkey, guido2004, Ethan-27, r937 and Mittineague and everyone else who took the time to look into this. I really appreciate it!
