Class

views_plugin_display

The default display plugin handler. Display plugins handle options and basic mechanisms for different output methods.

Code

public function unpack_handler(&$translatable, $storage, $option, $definition, $parents) {
  $output = '';

  // Cut the 's' off because the data is stored as the plural form but we need
  // the singular form.
  if ($option != 'header' && $option != 'footer' && $option != 'empty') {
    $type = substr($option, 0, -1);
  }
  else {
    $type = $option;
  }
  $types = views_object_types();
  foreach ($storage[$option] as $id => $info) {
    if (!empty($types[$type]['type'])) {
      $handler_type = $types[$type]['type'];
    }
    else {
      $handler_type = $type;
    }
    $handler = views_get_handler($info['table'], $info['field'], $handler_type);
    if ($handler) {
      $handler
        ->init($this->view, $info);
      $items = array_merge($parents, array(
        $type,
        $info['table'],
        $info['id'],
      ));
      $handler
        ->unpack_translatables($translatable, $items);
    }

    // Prevent reference problems.
    unset($handler);
  }
  return $output;
