FoxyCart is a very adaptable eCommerce system. Products are built on-the-fly as part of add to cart buttons that are just simple HTML. This means that you can integrate it with just about any CMS. In this screencast, we integrate it with WordPress. We make a special page template just for products. This page template loads the necessary FoxyCart files and automatically has an add to cart button that is controlled with custom fields in WordPress.
