Over on NETTUTS.com today there's a new tutorial about combining the CodeIgniter framework with the jQuery javascript library to make a simple, dynamic shopping cart application.

CodeIgniter is an open source PHP web application framework with a lot of features. Recently, thanks to the latest update, a new feature was added to this framework, called the Cart Class. In this tutorial, we're going to take advantage of this new class, and write a shopping cart system, with a touch of jQuery added in.

You'll probably want to be a bit familiar with CodeIgniter and how it works before getting started, but it wouldn't take much. Configuration file changes and code snippets for the model, view and controller of the cart are all provided. You can also download the source if you want to get started right away.
