Class

SearchApiEtDatasourceController: Provides multilingual versions of all entity types.

Code

public function getMetadataWrapper($item = NULL, array $info = array()) {

  // Since this is usually called with a "property info alter" callback
  // already in place (and only one value is allowed), we have to call
  // the existing callback from within our own callback to make it work.
  $property_info_alter = isset($info['property info alter']) ? $info['property info alter'] : NULL;
  $callback = new SearchApiEtPropertyInfoAlter($property_info_alter);
  $info['property info alter'] = array(
    $callback,
    'propertyInfoAlter',
  );

  // If the item isn't the object and a multilingual id is provided
  // extract the entity id to load and wrap the entity.
  if (SearchApiEtHelper::isValidItemId($item)) {
    $item = SearchApiEtHelper::splitItemId($item, SearchApiEtHelper::ITEM_ID_ENTITY_ID);
  }
  $wrapper = entity_metadata_wrapper($this->entityType, $item, $info);

  // If the item's language is set, let's set it on all wrapper fields,
  // so that their translated values get indexed.
  if (!empty($item->search_api_language)) {

    // Set language on the wrapper as a whole.
    $wrapper
      ->language($item->search_api_language);

    // Also try to set language on all wrapper fields, recursively.
    if (!empty($item->search_api_index)) {
      $this
        ->setLanguage($wrapper, $item->search_api_index->options['fields'], $item->search_api_language);
    }
  }
  return $wrapper;
}
