guy_schneerson's sandbox: commerce compact cart

A compact block for Cart / Shopping Basket

When all you need is a simple one liner:

Your cart contains 3 items. Total:£32.50 [ View Cart ] - [ Checkout ]

Featuring

• Total and quantity
• No use of views
• Both cart and empty cart use a template file
• Translatable messages

Other notes:
The module counts and totals 'product' line items, so shipping cost are excluded.
Simple templates are provided to enable theming.
Variables are provided for:

$quantity

the number of products in the cart

$cart_total

this contains the total + currency (formatted)

$order

The full order object for the shopping cart.

$currency_code

the currency of the current order

$order_total

the total of the order (unformatted)

The most commonly used are: $quantity and $cart_total
Note that the cart_total is formatted for the order currency.
The templates provided also create two variables for messages:

$cart_quantity_msg

e.g. your cart contains 3 items

$cart_total_msg

e.g. Total: £34.50

Message 'templates' are provided to sanitise and translate the cart messages:

$cart_quantity_msg = t('Your Shopping Bag contains %quantity item(s)', array('%quantity' => $quantity)) ;  
    $cart_total_msg = t('Total %cart_total', array('%cart_total' => $cart_total)) ;
