public function OrderEventSubscriber::onOrderUpdate in Commerce Stock 8

Acts on the order update event to create transactions for new items.

The reason this isn't handled by OrderEvents::ORDER_ITEM_INSERT is because that event never has the correct values.

Parameters

\Drupal\commerce_order\Event\OrderEvent $event: The order event.

File

src/EventSubscriber/OrderEventSubscriber.php, line 124

Class
