NodeController::attachLoad

protected function NodeController::attachLoad

protected NodeController::attachLoad(&$nodes, $revision_id = FALSE)

Attaches data to entities upon loading.

This will attach fields, if the entity is fieldable. It calls hook_entity_load() for modules which need to add data to all entities. It also calls hook_TYPE_load() on the loaded entities. For example hook_node_load() or hook_user_load(). If your hook_TYPE_load() expects special parameters apart from the queried entities, you can set $this->hookLoadArguments prior to calling the method. See NodeController::attachLoad() for an example.

Parameters

$queried_entities: Associative array of query results, keyed on the entity ID.

$revision_id: ID of the revision that was loaded, or FALSE if the most current revision was loaded.

  $typed_nodes = array();
  foreach ($nodes as $id => $entity) {
    $typed_nodes[$entity->type][$id] = $entity;
  }

  // Call object type specific callbacks on each typed array of nodes.
  foreach ($typed_nodes as $node_type => $nodes_of_type) {
    if (node_hook($node_type, 'load')) {
      $function = node_type_get_base($node_type) . '_load';
      $function($nodes_of_type);
    }
  }
  // Besides the list of nodes, pass one additional argument to
  // hook_node_load(), containing a list of node types that were loaded.
  $argument = array_keys($typed_nodes);
  $this->hookLoadArguments = array($argument);
