Display Type - List

Hi All,

Can we please add a new display type to the cvs branch so that taxonomy terms are displayed as unordered lists instead of just plain text?

I have altered the latest beta3 version using additions to hook_theme, hook_field_formatter_info and providing a new theme formatter function.

Hook_Theme:

function content_taxonomy_theme() {
  return array(
    'content_taxonomy_formatter_default' => array(
      'arguments' => array('element' => NULL),
    ),
    'content_taxonomy_formatter_list' => array(
      'arguments' => array('element' => NULL),
    ),
    'content_taxonomy_formatter_link' => array(
      'arguments' => array('element' => NULL),
    ),
  );
}

Hook_Field_Formatter_Info:

function content_taxonomy_field_formatter_info() {
  return array(
    'default' => array(
      'label' => t('As Text'),
      'field types' => array('content_taxonomy'),
      'multiple values' => CONTENT_HANDLE_CORE,
    ),
    'list' => array(
      'label' => t('As List'),
      'field types' => array('content_taxonomy'),
      'multiple values' => CONTENT_HANDLE_CORE,
    ),
    'link' => array(
      'label' => t('As Link'),
      'field types' => array('content_taxonomy'),
      'multiple values' => CONTENT_HANDLE_CORE,
    ),
  );
}

theme_content_taxonomy_formatter_list:

function theme_content_taxonomy_formatter_list($element) {
drupal_add_css(drupal_get_path('module', 'content_taxonomy') .'/content_taxonomy.css');
$term = taxonomy_get_term($element['#item']['value']);
return (check_plain($term->name)) ? '<ul class="content_taxonomy"><li>'.check_plain($term->name).'</li></ul>' : check_plain($term->name);
}

The way I have included the new display type requires extra css so I have included that too:

/* $Id: nodereference.css,v 1.1.2.1 2008/07/09 14:46:01 yched Exp $  */

/* CSS overrides for Views-based autocomplete results.
  - #autocomplete uses "white-space:pre", which is no good with
    Views' template-based rendering
  - Field titles are rendered with <label> in default templates,
    but we don't want the 'form' styling it gets under .form-item
*/

div.field-item ul.content_taxonomy {
  clear:both;
  margin-top:0px;
  margin-bottom:0px;
}
