Review: Pro Drupal Development by John VanDyk

,

If you’ve torn you hair out and still don’t really feel totally comfortable with the Drupal forms API, or with getting your module to affect the menu system or have lingering questions about anything in Drupal core, this book is a godsend. It is so much clearer and more accessible than the online documentation and the index is great. Within the first day I had it, it saved me a couple of hours of effort. Highly recommended.
