If you're a web programmer, your experiences have taught you certain lessons--and only some of them apply well to Drupal. Drupal has its own set of programming principles that require a different approach, and many programmers make mistakes when relying on skills they've used for other projects. This book will show you which programming techniques you can use--and which you should avoid--when building web applications with this popular content management framework.
Updated to cover both Drupal 7 and Drupal 8, the guidelines in this book demonstrate which programming practices conform to the Drupal way and which don't. The book also serves as an excellent guide for Drupal 7 programmers looking to make the transition to Drupal 8.
