I see you got it! :)
And I like the different page technique better, too!

Anyway, if you want to trust your users ( *NEVER DO THAT* ), maybe this
little change would work:


<?php
session_start();
if (isset($_POST['theSubmitButton'])) {
if ($_SESSION[$_POST['tid']]['submitted']) {

// OOPS!

} else {

$_SESSION[$_POST['tid']]['submitted'] = true;
// rest of script;

}
}
// ...

echo '<input type="submit" name="theSubmitButton">';
$tid = md5(time());
$_SESSION[$tid]['submitted'] = false;
echo '<input type="hidden" name="tid" value="', %tid, '">';

// ...
?>
