This tutorial covers a topic in Drupal 7 which may or may not be the version you're using. We're keeping this tutorial online as a courtesy to users of Drupal 7, but we consider it archived.
The first step to defining a custom field is telling Drupal that our module provides a field. This is done by implementing hook_field_info(), hook_field_formatter_info(), and hook_field_widget_info(). The combination of which provides some basic information about our field including a label, description, default settings, and basic information about how the field will be formatted and what widgets can be used for data collection.
In this lesson we'll implement the basics for the following hooks:
Doing so will allow us to enable our module and see our new field type appear in the list of available fields to add to a content type. The field won't do much beyond that yet, but it's a good start towards telling Drupal about our custom RGB field type.
If you want to just follow along and look at the already written code you can grab a copy in the companion files section of this page and use that to follow along.
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?
