Draft:Developer's FAQ

Is there an easy way to grab domestic shipping rates other than using the "func_get_shipping_methods_list" function?

I'm attempting to use the "func_get_shipping_methods_list" function, but I can't figure out how to override the destination address, even though I'm passing it to the function. We need to override the destination so that we calculate the shipping from the company address to our warehouse, rather than from the company address to the user's address.

To achieve your objective, you will have to use the func_get_shipping_methods_list function anyway. The function returns a PHP array.

In your case, the key setting is $config['General']['apply_default_country']. The 'Override destination address before shipping calculated' task is implemented here:

[~/www/xcart_4_4_x]$ grep -r --include='*.php' "apply_default_country.*Y" *|grep -v '=='|grep -v '!='
modules/Amazon_Checkout/func.php: $config['General']['apply_default_country'] = 'Y';
modules/Google_Checkout/gcheckout_callback.php: $config['General']['apply_default_country'] = 'Y';

Here is the code from modules/Amazon_Checkout/func.php

function func_amazon_get_shipping_methods12($cart)
{
...
  // Option adjustment to avoid empty($userinfo) checking
  // $userinfo will be provided by Amazon in callback
  $config['Shipping']['enable_all_shippings'] = 'Y';
  $userinfo = $cart['userinfo'];
  $products = func_products_in_cart($cart, (!empty($user_account['membershipid']) ? $user_account['membershipid'] : ''));

  $_need_shipping = func_cart_is_need_shipping($cart, $products, $userinfo, 'dont_check_free_ship_coupons');

  if (empty($_need_shipping)) {
    $result_cache[$md5_args] = false;
  return false;
}

// Some options require adjustment
$config['Shipping']['enable_all_shippings'] = 'N';

// Emulate the 'apply_default_country' option enabled
$config['General']['apply_default_country'] = 'Y';
$config['General']['default_country'] = $userinfo['b_country'];
$config['General']['default_zipcode'] = $userinfo['b_zipcode'];
$config['General']['default_state'] = $userinfo['b_state'];
$config['General']['default_city'] = $userinfo['b_city'];

$intershipper_recalc = 'Y';

x_load('shipping');
// Get list of all shipping methods that are potentially available for customers
$shipping_methods = func_get_shipping_methods_list($cart, $products, $userinfo);
...
}

Adjust $userinfo['b_*'] according to your warehouse address

Or use the code from modules/Google_Checkout/gcheckout_callback.php

If I wanted to grab the coupon codes being used on a specific order, where should I be looking? Is this included in the $cart data?

This variable stores the coupon code applied to the cart after cart recalculation:

$cart['coupon']

The same field is available in the sql xcart_orders table.
