Good Drupal 7 Coding tutorials
I would like to learn how to code custom modules for Drupal 7. Are there any good advanced online courses available which teach me to get an expert in Drupal 7 coding?
Lynda advance Drupal tutorial
You can try the Lynda online course - Advance Drupal. The course was authored by Tom Geller, who is a teacher and also works as a consultant on Drupal. I am not sure that this course will help you to create custom module directly. But it will help you to get some deep insight which may later prove to be helpful for customizing modules.
