In Detail

With great power comes... tremendous flexibility. Drupal is an award-winning open-source Content Management System, and the feature-packed sixth release is right around the corner. It's a modular system, with an elegant hook-based architecture, and great code. These are a few of the perks that make Drupal a choice platform for developers who want the power of an established CMS, but the freedom to make it work for them. From social networking to AJAX to e-commerce, the hundreds of existing modules attest to Drupal's flexibility. When you create a new module for Drupal, it fits seamlessly into the look and feel of your overall site. If you can think it in PHP, you can code it as a Drupal module.

Dive into Drupal module development as we create the Philosopher Biographies website, developing new modules and themes to meet practical goals. Create custom content types. Add AJAX functionality with the jQuery library. Use external XML APIs to add content to your site. Email newsletters to site members. Use themes. Empower administrators with extra features. And bundle it all up in a custom installation profile. You won't find a "hello world" here!
