Payment Module - How to pass shipping & tax totals

[JMega]

I'm trying to set up a payment module and I need to grab the total taxes and the total shipping costs and pass them along to this 3rd party payment processor.

 

I've got the total amount (including taxes and shipping) by doing the following:

 

number_format($params['cart']->getOrderTotal(true, 3), 2, '.', '')

 

Does anyone know what I should use to get the shipping cost and the amount of tax?

 

Thanks in advance

If it helps future searchers - the firsst argument of the call to getOrderTotal is whether to use taxes, and the second determines the value returned. Possible values for the second are:

Cart::ONLY_PRODUCTS
Cart::ONLY_DISCOUNTS
Cart::BOTH
Cart::BOTH_WITHOUT_SHIPPING
Cart::ONLY_SHIPPING
Cart::ONLY_WRAPPING
Cart::ONLY_PRODUCTS_WITHOUT_SHIPPING
Cart::ONLY_PHYSICAL_PRODUCTS_WITHOUT_SHIPPING

 

So to answer the original question,

$params['cart']->getOrderTotal(true, Cart::ONLY_SHIPPING)

 

should return the shipping cost (including taxes).

 

Depending on the tax you're after, something like

 

$params['cart']->getOrderTotal(true, Cart::BOTH) - $params['cart']->getOrderTotal(false, Cart::BOTH)

 

should so the trick.

 

Disclaimer - I haven't tested any of this code; I'm only answering because the question solved a problem for me.
