Act on field_attach_load().
This hook is invoked after the field module has performed the operation.
Unlike other field_attach hooks, this hook accounts for 'multiple loads'. Instead of the usual $entity parameter, it accepts an array of entities, indexed by entity ID. For performance reasons, information for all available entities should be loaded in a single query where possible.
The changes made to the entities' field values get cached by the field cache for subsequent loads.
See field_attach_load() for details and arguments.
function hook_field_attach_load($entity_type, $entities, $age, $options) {
// @todo Needs function body.
}
