Get zipcode inside track.phtml to track shipment of a order

Question

How can I get the zipcode of the order inside the track.html file?

I tried this, but that does not work:

<?php echo $this->escapeHtml($this->getShippingAddress()->getPostcode()) ?>

Answer 1

The block type of the track.phtml template is core/template so it's default without a method like $this->getShippingMethod().

If you check the shipment_new.html email template somewhere around the bottom the tracking block is included with the following statement

{{block type='core/template' area='frontend' template='email/order/shipment/track.phtml' shipment=$shipment order=$order}}

This means both the order and shipment are available in the data of the block class. Which means you can do this

<?php echo $this->escapeHtml($this->getOrder()->getShippingAddress()->getPostcode()) ?>
