$_GET and Form Validation

[eluser]WanWizard[/eluser]
The short answer: You can't. The Form validation library has $_POST hardcoded.

The long answer: If you still want this, your best bet is to copy the form validation library to get_validation.php, and replace all occurences of $_POST with $_GET. Imho that's a better bet than extending and messing with the code.
