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.

Class

NodeController

Controller class for nodes.

Code

protected function attachLoad(&$nodes, $revision_id = FALSE) {
 // Create an array of nodes for each content type and pass this to the
 // object type specific callback.
 $typed_nodes = array();
 foreach ($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(
 $argument,
 );
 parent ::attachLoad ($nodes, $revision_id);
}
