从 Magento 中的货件跟踪事件获取跟踪 ID

Question

sales_order_shipment_track_save_after我正在尝试从Magento 1.9.0.1 中的事件中获取跟踪号码。由于某种原因，该活动似乎不包括发货，因为$observer->getEvent()->getShipment()退货NULL。我使用了错误的事件吗？

这些是我的代码的相关部分：

配置.xml（模块）

<events>
  <sales_order_shipment_track_save_after>
    <observers>
      <pixelstore_sms>
        <type>model</type>
        <class>pixelstore_sms/observer</class>
        <method>shipments</method>
      </pixelstore_sms>
    </observers>
  </sales_order_shipment_track_save_after>
</events>

Observer.php（模型）

public function shipments($observer) {
    $event = $observer->getEvent();
    $shipment = $event->getShipment();
    if (!$shipment) {
        Mage::log('shipments event did not contain shipment', null, 'track.log');
        return false;
    }
    // We never reach this far
    $trackings = $shipment->getAllTracks();
    $tracking = end($trackings);
    $trackingId = $tracking->getNumber();
    // Here I would prefer to have the tracking ID in $trackingId
}

正如您可能已经猜到的，该if声明是匹配的。get_class()表明观察者是Varien_Event_Observer.

我是否观察到了错误的事件，或者是否应该调用其他方法来获取跟踪 ID？

Answer 1

我发现该事件包含Mage_Sales_Model_Order_Shipment_Trackkey 下的对象track。$event->getData('track')这意味着我可以通过或$event['track']直接从活动中获取它$event->getTrack()。所以这最终解决了我的问题：

public function shipments(Varien_Event_Observer $observer) {
  $event = $observer->getEvent();
  $track = $event->getTrack();
  $trackingId = $track->getNumber();

  // The shipment itself can be found in the track object,
  // and the order inside the shipment object:
  $shipment = $track->getShipment();
  $order = $shipment->getOrder();
}

这完全是对实际事件的误解。
