I'm building a kind of e-commerce site and I need to develop a shopping cart. My problem is this:
the client is browsing trough the products catalog and he/she want's to add products to the cart. When he/she clicks the "add to cart" link I need process that request (adding the product in the cart) without leaving the products catalog page. So the script that handles the products display on page must handle the add to cart option also.
How do I do that?
