function phone_process_field in Phone 7.2

Implements MODULE_process_HOOK().

We make use of this function to add RDF resource properties for foaf:phone.

We use process instead of preprocess, as we want to run after any other modules have done their thing so we have all the information.

File

./phone.module, line 1162

The phone module lets administrators use a phone number field type.

Code

function phone_process_field(&$variables) {
  if ($variables['element']['#field_type'] == 'phone' && module_exists('rdf')) {
    $element = $variables['element'];
    $field_name = $element['#field_name'];

    // Go over the attributes array if it exists and manuipulate it as required.
    if (isset($variables['item_attributes_array'])) {
      foreach ($variables['item_attributes_array'] as $delta => $attributes) {

        // If rel="foaf:phone" isset, then add the resource property.
        if (isset($attributes['rel']) && in_array('foaf:phone', $attributes['rel'])) {
          $variables['item_attributes_array'][$delta]['resource'] = $variables['items'][$delta]['phone']['number']['#href'];

          // We need to re-flatted our modified item_attributes_array.
          $variables['item_attributes'][$delta] = drupal_attributes($variables['item_attributes_array'][$delta]);
        }
      }
    }
  }
}
