通过优惠券为非折扣商品添加自定义捆绑购物车折扣

Question

我有 Woocommerce 购物车，我成功添加了 "bundle" 折扣，如果购物车数量为 5 件或更多，购物车中的每件商品可享受 7 美元的折扣。

我还想为某些产品启用优惠券。但我不想将捆绑折扣和优惠券折扣叠加在一起。

这是我目前添加捆绑折扣的方式：

add_action( 'woocommerce_cart_calculate_fees','wc_cart_quantity_discount', 10, 1 );
function wc_cart_quantity_discount( $cart_object ) {
if ( is_admin() && ! defined( 'DOING_AJAX' ) )
    return;

$discount = 0;
$cart_item_count = $cart_object->get_cart_contents_count();

if( $cart_item_count > 4 )
    $percent = 25;


$discount -= $cart_object->get_cart_contents_count() * 7;

if( $percent > 0 )
    $cart_object->add_fee( __( "Bundle discount", "woocommerce" ), $discount, true);
}   

例如：
我的购物车中有 5 件商品，其中 1 件商品已使用优惠券打折，可享受 35% 的折扣。
有没有办法通过应用的优惠券仅在 4 件非折扣商品上保留我的捆绑折扣？

I don't want to stack off plus 35% off. I only want the coupon to have precedence if it is applied without losing the discount on my other 4 items.

这里是钩子函数代码，它将添加每个非折扣购物车商品折扣</code></strong>当有购物车中至少有 5 件商品：</p> <pre><code>add_action( 'woocommerce_cart_calculate_fees','wc_cart_quantity_discount', 10, 1 ); function wc_cart_quantity_discount( $cart_object ) { if ( is_admin() && ! defined( 'DOING_AJAX' ) ) return; $cart_total_count = $cart_object->get_cart_contents_count(); $cart_items_count = 0; // Counting non discounted cart items (by a coupon discount) foreach( $cart_object->get_cart() as $cart_item_key => $cart_item ) if( $cart_item['line_subtotal'] == $cart_item['line_total'] ) $cart_items_count += $cart_item['quantity']; if( $cart_total_count > 4 ){ $discount = $cart_items_count * 7; $cart_object->add_fee( __( "Bundle discount", "woocommerce" ), -$discount, true); } }

代码进入您的活动子主题（或主题）的 function.php 文件或任何插件文件。

此代码已经过测试并且有效。
