My form exploit needs to be patched!

[GGLeague]

I have a form that includes global.php and uses $vbulletin->GPC data to create a post. I have no way of checking if they array is empty. !isset, empty, and if($vbulletin->GPC['field']) == "") aren't working. So, if I go to the page (not with form submission), it will post a thread with blank fields and if repeated, it will post again. An HTML script could be setup to screw that over :/ (spam posts) How can I check if the field is empty?

What is the code you are currently using?

PHP Code:

if($vbulletin->GPC['field'] == '')
{
//error message;
} 

Should work fine.
