string $bundle: The bundle name.
string $context: The context for which the maximum weight is requested. Either 'form' or 'display'.
string $context_mode: The view or form mode name.
int The maximum weight of the entity's components, or NULL if no components were found.
function hook_field_info_max_weight($entity_type, $bundle, $context, $context_mode) { $weights = array(); foreach (my_module_entity_additions($entity_type, $bundle, $context, $context_mode) as $addition) { $weights[] = $addition['weight']; } return $weights ? max($weights) : NULL; }
