How can I replicate "Send Tracking Information" behaviour in Magento using PHP

Question

I have a cronJob written in PHP which reads Tracking numbers from a CSV and updates in Magento.

My code looks like this

  if ($order->getShipmentsCollection()->getData()) {
            foreach ($order->getShipmentsCollection() as $shipment) {
                $shipmentid = $shipment->getId();
                $shipment = Mage::getModel('sales/order_shipment')->load($shipmentid);
                $trackdata = array();
                $trackdata['carrier_code'] = $data[22];  //get CARRIER_NAME from csv
                $trackdata['title'] = $data[22];    //get title from csv
                $trackdata['number'] = $data[20];       //get CONSIGNMENT_NO from csv

                $track = Mage::getModel('sales/order_shipment_track')->addData($trackdata);
                $shipment->addTrack($track);
                $transactionSave = Mage::getModel('core/resource_transaction')
                        ->addObject($shipment)
                        ->addObject($shipment->getOrder())
                        ->save();

                $shipment->sendEmail($email, ($includeComment ? $comment : ''));
            }
        } else {

            $convertor = Mage::getModel('sales/convert_order');
            $shipment = $convertor->toShipment($order);

            foreach ($order->getAllItems() as $orderItem) {
                if (!$orderItem->getQtyToShip()) {
                    continue;
                }
                if ($orderItem->getIsVirtual()) {
                    continue;
                }
                $item = $convertor->itemToShipmentItem($orderItem);
                $qty = $orderItem->getQtyToShip();
                $item->setQty($qty);
                $shipment->addItem($item);
            }

            $trackdata = array();
            $trackdata['carrier_code'] = $data[22];  //get carrier_code from csv
            $trackdata['title'] = $data[22];    //get title from csv
            $trackdata['number'] = $data[20];       //get track number from csv     
            $track = Mage::getModel('sales/order_shipment_track')->addData($trackdata);
            $shipment->addTrack($track);

            $shipment->register();
            $shipment->addComment($comment, $email && $includeComment);
            $shipment->setEmailSent(true);
            $shipment->getOrder()->setIsInProcess(true);

            $transactionSave = Mage::getModel('core/resource_transaction')
                    ->addObject($shipment)
                    ->addObject($shipment->getOrder())
                    ->save();

            $shipment->sendEmail($email, ($includeComment ? $comment : ''));
        }

It works well but only thing is that does not do what "Send Tracking Information" button, this button

I want to replicate its behaviour.

Actually when "Send Tracking Information" button is clicked email is sent via PackPin API to customer.

But with my code it doesn't send.

Answer 1

I don't know much about PackPin or the PackPin magento module (which I'm assuming is something you're using), but a few ideas that might be worth looking at:

1) You set $shipment->setEmailSent(true); prior to calling $shipment->sendEmail($email, ($includeComment ? $comment : ''));. If the PackPin module overrides the shipment model behavior, it's possible it checks for the value of emailSent prior to sending, and only sends if $emailSent is false.

2) (Again, assuming there's a PackPin module) - It's possible the module overrides the "Send Tracking Information" button with it's own method that doesn't use $shipment->sendEmail() and makes an API call within a controller method instead. I would dig in the module more to see how it's being sent when clicking that button.

Hope this helps.
