Drupal 7 Theming Cookbook

Overview of this book

<p>The greatest strength of Drupal lies in its design which, when employed correctly, allows developers to literally handcraft every aspect of a site, so that it looks and performs exactly how they want it to. While it is reasonably straightforward to download a Drupal theme and install it, doing anything beyond that is not. Using custom themes requires familiarity and experience with Drupal's theming system, especially if you want to easily administer and maintain your themes.</p> <p>Drupal 7 Theming Cookbook provides a plethora of recipes that enable Drupal template designers to make full use of its extensibility and style their site just the way they want it. It is a well-rounded guide which will allow users to take full advantage of Drupal's theming system.</p> <p>This cookbook starts with recipes which address the basics of Drupal's theme system, including regions and blocks. It then moves on to advanced topics such as creating a custom theme and using it to modify the layout and style of content. With the introduction of the Field API and the growing importance of Views and Panels in Drupal 7, chapters have been dedicated to each feature. You will also learn many techniques for dealing with Drupal&rsquo;s templating system, which will allow you create themes which surpass even the existing Drupal and contributed modules.</p>

Preface

Theming form elements from a module


Drupal form elements such as checkboxes and radio buttons are all rendered using the theme system and consequently, can be overridden just like any other theme function. In this recipe, we will be adding a new feature to the FIELDSET element by overriding theme_fieldset(). We will be demonstrating its use by adding a postscript to the Revision information fieldset present in every node form.

Getting ready

This recipe requires the use of the mysite module created earlier in this book. The Devel and Theme developer modules will also be used to identify the theme function to override.

How to do it...

Firstly, we need to identify how Drupal is going about theming a fieldset. The recommended method of doing so is to use the Theme developer module as follows:

  1. 1. Browse to a node form at, for example, node/add/story.

  2. 2. Locate the Revision information fieldset which, if collapsed, should be expanded.

  3. 3. Enable Themer info and click on an empty area in this fieldset...
