It seems like that what you need is some sort of session management, and since you doesn't use PHP4, you should take a look at http://phplib.netuse.de If you just need to generate a unique id, then take a look at http://www.php.net/manual/function.uniqid.php Regards, Lars Holm Nielse <lars@hankat.dk>
