Drupal 5 Views Recipes

Overview of this book

The Drupal View modules give you flexibility and freedom to customize the display of your web site's content. Although there are more than 100 views-enabled modules, few site administrators use Drupal Views to its full potential. This book will enable you to realize the fullest potential of this powerful resource by providing a wide variety of powerful recipes for creating and displaying a wide variety of views ñ essential classics you will use again and again to innovative display methods that will make your Drupal site stand out. Pick and choose the ones you would like to prepare for your web site. In this book you will find ninety-four recipes to create a wide selection of views. The list includes event listings, interactive calendars and timelines, maps, proximity search, podcasting, carousels, Views Fusion, and many more. You will also explore default views, views with CCK, and master a variety of ways to associate views with related content. Most people think of Views for site visitors. But Views can also be handy for site administrators. You will get to know the Views Bulk Operations module, along with Editable Fields, and Views Custom Fields. (You'll probably wonder why you never used them before!) If you want to take Views to the next level, the book contains a code-rich chapter on theming. However, you will find most of the recipes detailed by the author do not require any original coding at all. As you progress through the recipes, you will be immersed in such Drupal Views topics as fields, arguments, filters, exposed filters, sorting, style plug-ins, formatters, cloning and copying views. Because Drupal is a worldwide and ever adapting system, the author also includes great tips and resources for navigating the online Drupal community and expanding your knowledge of the recipes. Finally, there is an extensive Appendix, which includes listings of all default views, formatters and style plug-ins for Drupal 5, along with a categorized list of patches.

Recipe 76: Understanding how Theme functions are called


As our theme_pager function demonstrates, it is not unusual to find themeable functions calling other themeable functions. Being able to detect these building blocks is a good step toward deeper Drupal understanding.

Themeable functions are called by modules and themes using the theme() function. Some examples will be helpful:

General Example

theme_function_name is called using the following syntax:

theme('function_name', parameter, parameter…)

Specific Example #1

  1. Visit http://api.freestylesystems.co.uk/api/function/theme_views_view/5

    This is an excerpt of the views.module, containing the theme_views_view function. Each time a view is built this function is run.

  2. Locate the spot in the code where the theme_view_more function is called.

    theme('views_more', $view->real_url);

    (In the full code, the function result is assigned to the $output variable.)

    Make note of the surrounding "if statement" controlling the theme_views_more output.

        if ...
