Re: If Question!

Matt, Since I am using a plain text mail reader I do not see any section highlighted in red. I will however comment on the section I think you are referring to. :) This section: if (isset($_GET['try'])) May not work correctly. If the request was something like http://127.0.0.1/test.php?try= then the $_GET['try'] variable will be set to NULL and the isset() will return FALSE. If you instead check for the key existing and then the value that would be better. if(array_key_exists('try',$_GET) && $_GET['try'] == "blah") Would be a more precise check on the try variable. If I am not looking at the correct line please reply with the line that is having the problem.
