Let's combine our knowledge of implementing hooks and hook_form_alter() to customize a form built by another module, the user registration form. For the Anytown Farmer's Market site's user registration form, we want to introduce 2 new features: a mandatory "Accept terms of use" checkbox and custom validation to prevent registration with the username "anytown".
In this tutorial, we'll:
- Identify the form ID of the user registration form.
- Incorporate new elements into the user registration form.
- Implement additional validation logic.
By the end of this tutorial, you should be able to use hook_form_alter() to customize any existing Drupal form.
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?
