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.

Code

function attachLoad(&$queried_users, $revision_id = FALSE) {

    }
    else {

    }
  }

  // Add any additional roles from the database.
  $result = db_query('SELECT r.rid, r.name, ur.uid FROM {role} r INNER JOIN {users_roles} ur ON ur.rid = r.rid WHERE ur.uid IN (:uids)', array(':uids' => array_keys($queried_users)));
  foreach ($result as $record) {
    $queried_users[$record->uid]->roles[$record->rid] = $record->name;
  }
