Duplicate form submission

[Aureole]

How can I stop a form submitting twice if the submit button is pressed more than once WITHOUT Javascript. I tried this:

 

<?php
if($queried == 0) {
    // Query goes here...
    $queried = 1;
    updatePostCount($_SESSION['mem_id']);
    header('Location: viewtopic.swr3?id='.$_GET['id'].'');
}
?>

 

I figured that would work but it doesn't...

No, it wont, on resubmission, $queried is not set. You're looking at either Javascript, or not allowing a duplicate field in the database, i.e. if you're taking someones name, don't allow consecutive id's with exactly the same name.
