Drupal 7 Module Development
In this course, you'll learn how to leverage Drupal's API by creating custom modules. You'll develop a module step by step and learn how to navigate the extensive documentation available and determine where you can hook into the system and add your new functionality. This course was designed for those who have experience with site building and knowledge of PHP.
Drupal is a modular, open source web content management framework that ships with basic functionality in the form of core modules. For the most part, you add new functionality with third party modules (known as contributed modules) that can be downloaded from Drupal.org. At some point you may find limitations. You may want to modify functionality in a contributed module or core. You may want to move your configuration to code, or access an external data source.
Custom code is expensive to maintain, risky to a project and creates a dependency on the people who wrote it. So while it is necessary to write some code on the vast majority of large Drupal sites, we strive to practice configuration before coding. You can accomplish a lot just by picking the right modules and configuring them to suit your needs.
