[SOLVED] Submit once...

[Aureole]

Is there any way using PHP to make sure that once someone clicks Submit if they click it again it won't send the data twice? If not is there any alternative using Javascript or something?

I use this method, don't see any issue with it

form.php

<?php
//Add this to form
$rand = rand(0,10000);
echo "<input type=\"hidden\" name=\"FormID\" Value=\"".$rand."\" />";
?>

processer.php

<?php
//At top
if($_SESSION['submitted'] == "yes" && $_POST['FormID'] == $_SESSION['FormID']){
exit($_POST['FormID']."Has Been Submitted");
}
//in processing part
if(processed){
$_SESSION['submitted'] = "yes";
$_SESSION['FormID'] = $_POST['FormID'];
?>

Hmm...that looks like an interesting way to do it, thanks a lot.
