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.
This chapter shows how to cluster different form elements into fieldsets as well as how to expand the Forms API renderable array a tree that preserves the structure and hierarchy of the form. We'll expand the Form Fun example module and talk about the #tree property. This video uses krumo() and dsm() functions. You will need to download, install, and enable the devel module to use these functions. These functions allow you to see what variables are available to you. To accomplish the same task without using the devel module, you can add the following snippet to your module:
drupal_set_message('' . print_r($vars, true) .'');
Note: There is a typo in the code used in this video. The function
form_fun_tree() is missing a parameter, and should be as follows
function form_fun_tree($form, &$form_state).
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?
