Get Tracking ID from Magento Dispatch Tracking Event

Question

I am trying to get the tracking number from an event sales_order_shipment_track_save_afterin Magento 1.9.0.1. For some reason, the event does not seem to include sending because it $observer->getEvent()->getShipment()returns NULL. Am I using the wrong event?

These are the relevant parts of my code:

config.xml (module)

<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 (model)

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
}

As you might have guessed, the operator ifmatches. get_class()shows that the observer Varien_Event_Observer.

Am I observing the wrong event or is there some other method that I have to call to get the tracking id?

Answer 1

, Mage_Sales_Model_Order_Shipment_Track track. , $event->getData('track'), $event['track'] $event->getTrack(). , :

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();
}
