function hook_uc_coupon_apply in Ubercart Discount Coupons 7.2

Same name and namespace in other branches

1. 7.3 uc_coupon.api.php \hook_uc_coupon_apply()

hook_uc_coupon_apply().

Invoked whenever a valid coupon is applied to an order. May be invoked than once for the same coupon if it becomes invalid due to change in cart contents.

Note that you should not do anything in your hoook implementation which causes the current cart contents to be rebuilt. This includes calls to uc_cart_add_item() without explicitly setting the $rebuild argument to false. And, since coupons may be submitted on the checkout page after the cart contents are frozen, updates to the cart contents may fail under some circumstances anyway.

Parameters

$coupon: The fully validated coupon which was applied.
