Module developers can add new elements to a form by adding their definition to the $form array in the buildForm() method of their controller or via an implementation of hook_form_alter(). Doing so requires knowing the element #type, and details about any element-type-specific properties.
In this tutorial we'll:
- Determine the element type to use for the HTML input element we want to use
- Consult the documentation for the two form element types we're using
- Add a checkbox and a select list to our form via the
buildForm()method of our form controller
By the end of this tutorial you'll know how to add new elements to an existing $form array in order to collect additional data from users.
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?
