I’ve recently finished updating all shopping carts to integrate with e-Junkie and Paypal on Glee Gum. I built this website last year using Drupal, PHP, and jQuery. The individual carts were built to integrate with Paypal, but there was no persistent shopping cart throughout the site. By adding e-Junkie functionality, the sitewide shopping cart is persisted throughout the user’s session and can be added to and update throughout their visit before proceeding to PayPal checkout.
