Question

我正在尝试从Magento 1.9.0.1中的sales_order_shipment_track_save_after事件中获取跟踪号。出于某种原因，该事件似乎不包括货件，因为$observer->getEvent()->getShipment()返回NULL。我使用了错误的事件吗？

这些是我的代码的相关部分：

config.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那样，if语句匹配。 get_class()表明观察者是Varien_Event_Observer。

我是否观察到错误的事件，或者是否有其他方法我应该致电以获取跟踪ID？

Answer 1

我发现该事件包含密钥Mage_Sales_Model_Order_Shipment_Track下的track对象。这意味着我可以通过$event->getData('track')，$event['track']或$event->getTrack()从事件中获取。所以这就是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();
}

对于实际事件中包含的内容，这完全是一种误解。

Answer 2

它应该能够检索订单对象，即使是作为基础观察者。

public function shipments(Varien_Event_Observer $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
$trackingId = $observer->getOrder()->getTrackingNumbers();
// Here I would prefer to have the tracking ID in $trackingId
}

从Magento的货运跟踪活动中获取跟踪ID
