Danny Englander: software engineer with a passion for learning something new every day
In my last post, I discussed my new photography site I'm building and theming with Drupal. The site is responsive and I've been searching for an ideal responsive touch friendly multi-level menu. I looked at and tried several jQuery plugins, CSS3 styles and a few Drupal Modules but nothing was quite right.
Lately, I've been devoting much of my free time to developing better methods of Drupal theming to achieve streamlined processes, simplicity and minimalistic code.
A few months ago, I became a full Drupal contributor on drupal.org with my theme Bamboo. I have to say that contributing to Drupal has been an eye opening experience and extremely rewarding.
In my last article I demonstrated how to extract basic data from field array elements which is ideal for custom node theming. The key to this is using *field_get_items*. I'll expand upon that by adding in additional Drupal API functions to enhance and format these Field array elements.
In this article, I'll show how to really dig into data associated with a field and for that I'll use a preprocess function in your theme's template.php for the logic and then a variable for presentation in a custom node template.
