Following inline documentation on example shipping module api, I have an implementation of hook_commerce_shipping_services_info(), in which I set callback function for 'rate', 'details_form' etc.
I'm trying to calculate the rate based on the zip code entered by the customer, but the callback for 'rate' only takes two arguments, which are $shipping_services and $order. I dpm both objects, but didn't see any shipping information, entered on the previous page (checkout). The field [commerce_customer_shipping] has
Array
(
[und] => Array
(
[0] => Array
(
[profile_id] => 2
)
)
)
How do I get the values for the individual fields, such as address, city, and zip code?
