Add the filtering to the query.

Potentially redundant if the parent class could be replaced with an IN handler.

Overrides views_handler_argument_string::query

Views Argument Handler class implementation.

Class

views_menu_reference_handler_argument_current_path

Argument handler to compare a views_menu_reference field against a given path.

Code

public function query($group_by = FALSE) {
  $this
    ->ensure_my_table();

  // The given path.
  $value = $this->argument;

  // !!!!!!! IMPORTANT !!!!!! FROM HERE ON THIS IS COMPLETELY IDENTICALLY
  // TO THE ARGUMENT IMPLEMENTATION IN "views_menu_reference_handler_argument_current_path.inc".
  // IF YOU CHANGE SOMETHING HERE, ALSO CHANGE IT THERE! ;)
  // Get the parents hierarchy of the given path, which is a simple array,
  // keyed by the depth and a + Separator for elements including children.
  // These keys are the depth value the field has to match together with the MLID:
  // The values are the MLIDs the field has to match together with the depth.
  $path_parents_hierarchy = views_menu_reference_get_link_path_parents_hierarchy($value);
  $field_mlid = $this
    ->get_field();
  $field_depth = str_replace('mlid', 'depth', $this
    ->get_field());
  if (!empty($path_parents_hierarchy)) {

    // Each level is compared by an OR, because if just one level matches,
    // the related entity is linked to the menu item.
    $level_conditions = db_or();

    // Add the Only-Level-Condition (No below menu items included)
    foreach ($path_parents_hierarchy as $level => $mlids) {

      // DEPTH AND MLID have to match in one field. If both match, the related
      // entity is linked to the menu item.
      $condition = db_and()
        ->condition($field_mlid, $mlids, 'IN')
        ->condition($field_depth, $level);
      $level_conditions
        ->condition($condition);
    }

    // Add the conditions to the query.
    $this->query
      ->add_where(0, $level_conditions);
  }
  else {

    // There is no hierarchy for the path that might match, so there can
    // not be a matching related node. We represnt this knowledge by setting
    // the condition totally false (1=0).
    $this->query
      ->add_where_expression(0, '1=0');
