Handling Redirection from an Event in Shopware
When using Shopware, we needed to redirect users from an event to a specific URL. We achieved this by creating a new custom exception and throwing it when necessary at an event. An event listener then handled this exception and generated a redirection response. This approach ensured seamless user redirection and provided clear feedback for invalid data or processes.
Issue Faced- Redirection from an Event
This project required redirecting users from an order-placed event to a specific URL. This redirection needed to be handled gracefully through custom exception handling in Shopware.
Solution
To address this, we can create a custom exception in Shopware and handle the redirection within an event. Below are the steps to achieve this:
Step 1: Create a Custom Exception
First, create a custom exception class by extending an existing Shopware exception.
php
| 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 | #[Package('checkout')] class InvalidErpOrderException extends InvalidOrderException { public function __construct(string $orderId, ?\Throwable $e = null) { parent::__construct($orderId); } public function getErrorCode(): string { return 'CHECKOUT__INVALID_ERP_ORDER_ID'; } public function getStatusCode(): int { return Response::HTTP_NOT_FOUND; } } |
Step 2: Throw the Custom Exception
Throw the custom exception when a specific condition is met in your event handling code.
php
| 1 2 3 | if ($exception) { throw new InvalidErpOrderException($order->getId()); } |
Step 3: Create and Handle the exception in ExceptionEvent
Next, create an event listener that listens for exceptions and handles the redirection.
php
| 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 | class ExceptionSubscriber implements EventSubscriberInterface { public static function getSubscribedEvents(): array { return [ KernelEvents::EXCEPTION => 'onException', ]; } public function onException(ExceptionEvent $event) { if ($event->getThrowable() instanceof InvalidErpOrderException) { $request = $event->getRequest(); $orderId = $event->getThrowable()->getParameters('orderId'); $redirectResponse = new RedirectResponse($this->container->get('router')->generate('frontend.account.edit-order.page', ['orderId' => $orderId]) . '?error-code=INVALID_ERP_RESPONSE'); $event->setResponse($redirectResponse); } } } |
Step 4: Register the Event Subscriber
Ensure that your event subscriber is registered in your plugin’s services configuration.
XML
| 1 2 3 4 5 | <service id="Example\Plugin\EventSubscriber\ExceptionSubscriber"> <tag name="kernel.event_subscriber"/> </service> |
Conclusion
Following these steps, you can handle redirection from an event in Shopware using a custom exception. This approach ensures that the redirection is handled smoothly and that users are properly informed when an exception is encountered. This solution improves the user experience by providing clear feedback and navigation. Consider hiring a Shopware developer or consulting a Shopware development agency for expert assistance.
