Question

由于我们可以在订单中对每种产品应用不同的优惠券，有什么方法可以知道哪种优惠券适用于哪种产品？我使用了$order->get_used_coupons()功能，但它只返回使用过的优惠券代码。

请帮助解决方案。感谢。

2016年6月为Woocommerce 2.5.x制作的示例（在Woocommerce 3 +中不起作用）

此示例基于已编译的搜索：

function wc_my_order_coupons( $order_id ) {
    $order = new WC_Order( $order_id );

    // checking if order has some used coupons
    if( sizeof($order->get_used_coupons()) > 0 ) {
        foreach( $order->get_used_coupons() as $coupon_code ) {

            // Retrieving the coupon ID
            $post_obj = get_page_by_title($coupon_code, OBJECT, 'shop_coupon');
            $coupon_id = $post_obj->ID;

            // here is a list of most all data that you can use for a coupon
            $cp_discount_type = get_post_meta( $coupon_id, 'discount_type', true );
            $cp_amount = get_post_meta( $coupon_id, 'coupon_amount', true );
            $cp_indiv_use = get_post_meta( $coupon_id, 'individual_use', true );
            $cp_products = get_post_meta( $coupon_id, 'product_ids' ); 
            $cp_excl_products = get_post_meta( $coupon_id, 'exclude_product_ids' );
            $cp_usage_limit = get_post_meta( $coupon_id, 'usage_limit', true );
            $cp_expiry_date = get_post_meta( $coupon_id, 'expiry_date', true );
            $cp_apply_before_tax = get_post_meta( $coupon_id, 'apply_before_tax', true );
            $cp_free_shipping = get_post_meta( $coupon_id, 'free_shipping', true ); 

            // Getting the products in this order_id
            $items = $order->get_items();
            foreach ($items as $key => $item) {
                $product_name = $item['name'];
                $product_id = $item['product_id'];

                // Example: we use product_ids authorized in the coupon $cp_products
                if (in_array($product_id, $cp_products)) {
                    echo $product_name . 'uses the coupon: ' . $coupon->code . '<br>';
                }
            }
        }
    }
}
