Hi
I do it using sessions with:
//Check for a reload
$hash = mhash(MHASH_SHA1,serialize($HTTP_POST_VARS));
$hash = bin2hex($hash);
if($hash == $Hash):
$reload = "Yes";
echo "reload <br>";
endif;
$Hash is registered in the session.

Does anyone know of a way to stop the user from refreshing a page several times. i.e if I add a value to a database using a form and PHP, I don't want the user to be able to simply press refresh and add the value to the database again.
