[Changing Form Action Field]

Hi there,

 

I was wondering if it was possible to change a forms action field with PHP.

 

Basically, if there are several checkboxes for the user to select and a specific checkbox was selected, how would I redirect users to an alternative webpage on submit?

 

I've been playing around with several methods, and one of them was:

 

<?php

if(isset($_POST['Example']) &&
   $_POST['Example'] == 'FormValueGoesHere')
{
    echo ('./page1.php');
}
else
{
    echo ('./page2.php');
}   

?>

 

But the form action would only display page1.php even with nothing selected.

 

Maybe I'm just being stupid because it's getting late, but I'd appreciate any assistance.

 

Thanks
