Drupal 7 Theming Cookbook

By: Karthik Kumar

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>

Getting ready

We will be using the mysite module created earlier in this book. We will be adding two image buttons one for Save and the other for the Preview button to the form for a node type named story. It is assumed that these images are available as save.png and preview.png, and stored in the mysite module's images folder.

It is also worthwhile familiarizing ourselves with the syntax and general vagaries of the button, image_button, and submit form element types via the Form API reference manual at http://api.drupal.org/api/drupal/developer--topics--forms_api_reference.html/7#image_button.

How to do it...

As we are altering forms, we will be performing the following steps in the mysite module as follows:
