Provides moderation filters for Views.

Class

workbench_moderation_handler_filter_moderated_type

Filter by whether a node type has moderation enabled or not.

Code

function query() {
  if (!isset($this->value) || $this->value === NULL) {
    return;
  }
  $node_types = workbench_moderation_moderate_node_types();

  // If there are no node types using moderation set this variable to an array with a blank value.
  // This will force the query to return no values.
  if (empty($node_types)) {
    $node_types = array(
      '',
    );

    // Tell users to configure content types for moderation
    // It's conceivable that a hook_menu_alter has changed the permission needed to get to admin/structure/types
    // and as such, perhaps a better check should be used here.
