WC_Abstract_Order::remove_coupon │ public │ WC 3.2.0

Remove a coupon from the order and recalculate totals.

Coupons affect line item totals, but there is no relationship between coupon and line total, so to remove a coupon we need to work from the line subtotal (price before discount) and re-apply all coupons in this order.

Manual discounts are not affected; those are separate and do not affect stored line totals.

Method of the class: WC_Abstract_Order{}

No Hooks.

Returns

true|false. TRUE if coupon was removed, FALSE otherwise.

Usage

$WC_Abstract_Order = new WC_Abstract_Order();
$WC_Abstract_Order->remove_coupon( $code );

$code(string) (required)

Coupon code.
