从 WooCommerce 3.7 开始,您现在应该在 WC_Order 实例对象上使用 WC_Abstract 方法 get_coupon_codes() 从订单中获取已使用的优惠券,因为 get_used_coupons() 方法已弃用。
所以你将在代码中替换:
foreach( $order->get_used_coupons() as $coupon_code ){
作者:
foreach( $order->get_coupon_codes() as $coupon_code ){
然后您可以获得优惠券详细信息,例如:
foreach( $order->get_coupon_codes() as $coupon_code ) {
// Get the WC_Coupon object
$coupon = new WC_Coupon($coupon_code);
$discount_type = $coupon->get_discount_type(); // Get coupon discount type
$coupon_amount = $coupon->get_amount(); // Get coupon amount
}

首先,自 WooCommerce 3 以来,您无法再访问 WC 对象属性。
您现在应该使用 WC_Coupon getter methods 从 WC_Coupon 对象实例中获取优惠券详细信息...
在您的情况下,您必须使用get_discount_type() 方法或is_type( 'cash_back_fixed' ) 方法......
方法如下:
// Get an instance of WC_Order object
$order = wc_get_order( $order_id );
// Coupons used in the order LOOP (as they can be multiple)
foreach( $order->get_used_coupons() as $coupon_code ){
// Retrieving the coupon ID
$coupon_post_obj = get_page_by_title($coupon_code, OBJECT, 'shop_coupon');
$coupon_id = $coupon_post_obj->ID;
// Get an instance of WC_Coupon object in an array(necessary to use WC_Coupon methods)
$coupon = new WC_Coupon($coupon_id);
// Now you can get type in your condition
if ( $coupon->get_discount_type() == 'cash_back_percentage' ){
// Get the coupon object amount
$coupon_amount1 = $coupon->get_amount();
}
// Or use this other conditional method for coupon type
if( $coupon->is_type( 'cash_back_fixed' ) ){
// Get the coupon object amount
$coupon_amount2 = $coupon->get_amount();
}
}
要获得优惠券折扣金额(也可以使用优惠券类型方法),方法如下:
$order = wc_get_order( $order_id );
// GET THE ORDER COUPON ITEMS
$order_items = $order->get_items('coupon');
// print_r($order_items); // For testing
// LOOP THROUGH ORDER COUPON ITEMS
foreach( $order_items as $item_id => $item ){
// Retrieving the coupon ID reference
$coupon_post_obj = get_page_by_title( $item->get_name(), OBJECT, 'shop_coupon' );
$coupon_id = $coupon_post_obj->ID;
// Get an instance of WC_Coupon object (necessary to use WC_Coupon methods)
$coupon = new WC_Coupon($coupon_id);
## Filtering with your coupon custom types
if( $coupon->is_type( 'cash_back_fixed' ) || $coupon->is_type( 'cash_back_percentage' ) ){
// Get the Coupon discount amounts in the order
$order_discount_amount = wc_get_order_item_meta( $item_id, 'discount_amount', true );
$order_discount_tax_amount = wc_get_order_item_meta( $item_id, 'discount_amount_tax', true );
## Or get the coupon amount object
$coupons_amount = $coupons->get_amount();
}
}
所以要获得优惠券价格,我们使用WC_Coupon get_amount()方法
