One way of doing this is to store the shopping cart as session data and using a class to read the session rather than the DB. Doing it this way means that the DB is only accessed before the shopper puts the item in their cart. Once it's there, the sesion holds the data and the DB load is reduced. We use this system in many of our sites. Regards Andrew -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
