如何为创建的每个新订单、产品等订阅 DrupalCommerce 2X 事件

How to Subscribe to DrupalCommerce 2X Events for every new Order, Product etc is created(如何为创建的每个新订单、产品等订阅 DrupalCommerce 2X 事件)

问题描述

我需要能够编写一个插件来获取订单、产品等，每当在 DrupalCommerce 2X 中创建新订单、产品时.但我似乎无法弄清楚商务部希望我怎么做.我没有看到任何可以为我提供数据的 *events 文件.

I need to be able to write a Plugin that gets the orders, product, etc., whenever a new Order, Product is created in DrupalCommerce 2X. but I can't seem to figure out how Commerce wants me to do it. I don't see any *events files that would give me the data.

看起来 Commerce 希望我创建一个单独的事件流插件来添加我想要的步骤，但我似乎找不到关于实现我自己的事件流的文档.

It looks like Commerce wants me to create a separate Event Flow plugin that would add the step I want, but I can't seem to find documentation about implementing my own Event Flow.

您能否在创建订单或产品时指导我运行我的代码的正确路径?我在正确的道路上吗?你能指出事件/事件订阅者流的开发文档吗?

Can you guide me to the right path of running my code when the order or product is created? Am I on the right path? Can you point to Events/EventSubscriber Flow development docs?

推荐答案

订单完成后，系统调用 commerce_order.place.post_transition.所以您需要在结帐完成时创建一个事件.

On order complete, system call the commerce_order.place.post_transition. so You need to create an Event on Checkout complete.

对转型做出反应

示例 - 对订单放置"转换做出反应.

Example - reacting to the order 'place' transition.

// mymodule/src/EventSubscriber/MyModuleEventSubscriber.php
namespace Drupalmy_moduleEventSubscriber;

use SymfonyComponentEventDispatcherEventSubscriberInterface;
use Drupalstate_machineEventWorkflowTransitionEvent;

class MyModuleEventSubscriber implements EventSubscriberInterface {

  public static function getSubscribedEvents() {
    // The format for adding a state machine event to subscribe to is:
    // {group}.{transition key}.pre_transition or {group}.{transition key}.post_transition
    // depending on when you want to react.
    $events = ['commerce_order.place.post_transition' => 'onOrderPlace'];
    return $events;
  }

  public function onOrderPlace(WorkflowTransitionEvent $event) {
    // @todo Write code that will run when the subscribed event fires.
  }
}

告诉 Drupal 关于你的事件订阅者

Telling Drupal About Your Event Subscriber

您的事件订阅者应添加到模块基本目录中的 {module}.services.yml.

Your event subscriber should be added to {module}.services.yml in the base directory of your module.

以下将注册上一节中的事件订阅者:

The following would register the event subscriber in the previous section:

# mymodule.services.yml
services:
  my_module_event_subscriber:
    class: 'Drupalmy_moduleEventSubscriberMyModuleEventSubscriber'
    tags:
      - { name: 'event_subscriber' }
