Actually, it's easily solvable. You have two scripts - let's call them
additem.php and showcart.php
when you add an item to the cart, it calls additem.php, which does the
actual work of putting the item in the cart. But it doesn't output anything.
When it's done processing the added item, additem.php uses header() to call
showcart.php, which displays the cart. If you hit refresh at this point,
you're only refreshing showcart.php, and not processing the added item
again.
