Definition of views_handler_field_field.

Class

views_handler_field_field

A field that displays fieldapi fields.

Code

function field_language($entity_type, $entity) {
  global $language_content;

  if (field_is_translatable($entity_type, $this->field_info)) {
    $default_language = language_default('language');
    $language = str_replace(array('***CURRENT_LANGUAGE***', '***DEFAULT_LANGUAGE***'), 
    array($language_content->language, $default_language), 
    $this->view->display_handler->options['field_language']);

    // Give the Field Language API a chance to fallback to a different language
    // (or LANGUAGE_NONE), in case the field has no data for the selected language.
    // field_view_field() does this as well, but since the returned language code
    // is used before calling it, the fallback needs to happen explicitly.
    $language = field_language($entity_type, $entity, $this->field_info['field_name'], $language);

    return $language;
  }
  else {
    return LANGUAGE_NONE;
  }
}
