Theming Formsten steps to beautiful Drupal forms

About this talk● Matt Haughey (MetaFilter) once said, “Forms are tedious, confusing, often

poorly designed, and most people equate their use with things like paying taxes.” Forms are often overlooked by themers because the code seems complicated and the forms are good enough that the hassle of learning the code does not seem to be worth the trouble. But in Drupal 6 theming forms has gotten a WHOLE LOT EASIER!

● In this session you will learn how to make your forms look the way you want. We'll start by looking at some great helper modules you can install to make forms a little sleeker. And then we'll move on to the basics of using the developer module to identify, and theme, form components. We'll specifically look at altering CCK forms although the techniques will apply to other Drupal forms too!

● If you've had tears of joy or tears of frustration from theming forms in Drupal 6, please bring your experiences to share with others.

● This talk is based on content from Front End Drupal—a Drupal theming book published by Pearson Education. You can read it in draft format at http://safari.informit.com/9780137007752. The print publication should be available Spring 2009 ish.

5Three golden rules to theming forms:1. http://api.drupal.org/api/group/themeable/6

2. Drupal stores form information in an array that can be manipulated with functions in #1.

3. Register unique forms to make unique changes.

7Identify the unique ID for the form.

8In template.php create:

function THEMENAME_form_id ($form) {// stuff goes in here

}

Alternate(register your own form)

function THEMENAME_theme() {return array('your_specific_form_id' => array (

'arguments' => array ('form') => NULL),),

);}

9Reset (or unset) form valuesfunction THEMENAME_form_id ($form) {

// set your new form data/values/text/etc$form['buttons']['submit']['#value'] = “YARR”;$form['title']['#title'] = t('New label text');// put the values back into the Drupal formreturn (drupal_render($form));

}
