Question

I want to use Shipping address zip code in this file

app/code/core/Mage/Shipping/Model/Carrier/Tablerate.php

I want to use it in this function
public function collectRates(Mage_Shipping_Model_Rate_Request $request){}

Is there any way to access the zip code there?

Answer 1

You can get the postcode like this:

var_dump($request->getDestPostcode());

To see all the important data of the $request object:

var_dump($request->getData());
