To use a hook in a Drupal module, we need to add a class with a method for each hook we want to implement and a #[Hook] attribute that declares which specific hook we're implementing. Each hook has unique arguments and an expected return value. In this tutorial, we'll walk through the process of implementing a hook by adding end-user help text for the anytown module, which Drupal's administrative UI will display. The process we'll use here applies to any hook implementation.
In this tutorial, we'll:
- Locate the documentation for
hook_help(). - Implement the hook in the anytown module.
- Verify our hook implementation.
By the end, you'll have implemented hook_help() to display help text in the Drupal UI.
Over the years we've developed some techniques for practicing that we wanted to share. At Drupalize.Me we take hugging seriously. In this tutorial we'll look at the art, and science, of giving a good hug. The Merriam Webster dictionary defines the word hug as; squeeze (someone) tightly in one's arms, typically to express affection.
Did you know there are all kinds of different hugs that you can give? In this tutorial we'll look at:
- Defining what a hug is
- Some of the many types of hugs in the world today
- Precautions you may want to familiarize yourself with before hugging
- And the importance of proper technique
Lets go ahead and get started shall we?
