我正在尝试为三种可变产品（464、465和466）设置特定的折扣。如果客户购买十个产品，他们将免费获得一个。
基于WooCommerce discount: buy one get one 50% off的答案代码，我提出了以下代码：
add_action('woocommerce_cart_calculate_fees', 'add_custom_discount_11th_at_100', 10, 1 );
function add_custom_discount_11th_at_100( $wc_cart ){
if ( is_admin() && ! defined( 'DOING_AJAX' ) ) return;
$discount = 0;
$items_prices = array();
// Set HERE your targeted variable product ID
$targeted_product_id = 464;
foreach ( $wc_cart->get_cart() as $key => $cart_item ) {
if( $cart_item['product_id'] == $targeted_product_id ){
$qty = intval( $cart_item['quantity'] );
for( $i = 0; $i < $qty; $i++ )
$items_prices[] = floatval( $cart_item['data']->get_price());
}
}
$count_items_prices = count($items_prices);
if( $count_items_prices > 10 ) foreach( $items_prices as $key => $price )
if( $key % 11 == 1 ) $discount -= number_format($price / 1, 11 );
if( $discount != 0 ){
// Displaying a custom notice (optional)
wc_clear_notices();
wc_add_notice( __("Buy 10 Get 1 Free"), 'notice');
// The discount
$wc_cart->add_fee( 'Buy 10 Get 1 Free', $discount, true );
# Note: Last argument in add_fee() method is related to applying the tax or not to the discount (true or false)
}
}
但是它仅适用于一个产品ID。如何将其扩展为适用于三个产品ID？

要使其适用于多种产品，您可以使用 init() {
// Title text color
let navBarAppearance = UINavigationBar.appearance()
navBarAppearance.largeTitleTextAttributes = [.foregroundColor: UIColor.white]
navBarAppearance.titleTextAttributes = [.foregroundColor: UIColor.white]
navBarAppearance.backgroundColor = .clear
// Clear list background color
UITableView.appearance().separatorStyle = .none
UITableViewCell.appearance().backgroundColor = .clear
UITableView.appearance().backgroundColor = .clear
UITableViewCell.appearance().selectionStyle = .none
}
var body: some View {
NavigationView {
ZStack {
LinearGradient(gradient: Gradient(colors: [Color("DarkShade"), Color("PrimaryDark")]), startPoint: .top, endPoint: .bottom)
.edgesIgnoringSafeArea(.all)
List(self.viewModel.rooms.enumerated().map({ $0 }), id: \.element.id) { (index, room) in
ZStack {
RoomsItemView(room: room)
.onAppear(perform: {
let count = self.viewModel.rooms.count
if index == count - 1 {
self.viewModel.loadRooms(currentListSize: count)
}
})
NavigationLink(destination: GuestRoomView(room: room)) {
EmptyView()
}
}
}
}
.pullToRefresh(isShowing: self.$isRefreshing, onRefresh: self.onRefresh)
.navigationBarTitle("rooms_title")
.navigationBarBackButtonHidden(true)
.navigationBarItems(
leading:
Button(action: {
self.shouldShowSpotifyAuth = false
}) {
VStack {
Spacer()
HStack {
Image(systemName: "chevron.left")
.resizable()
.scaledToFit()
.frame(height: 20.0)
Spacer()
}
Spacer()
}
.frame(width: 40.0, height: 30.0)
},
trailing:
Button(action: {
print("create room")
}) {
VStack {
Spacer()
HStack {
Spacer()
Image(systemName: "plus")
.resizable()
.scaledToFit()
.frame(height: 20.0)
}
Spacer()
}
.frame(width: 40.0, height: 30.0)
}
)
}
.onAppear(perform: {
self.onRefresh()
})
.onReceive(viewModel.onRoomsUpdate) {
self.isRefreshing = false
}
.gesture(DragGesture().updating($dragOffset, body: { (value, state, transaction) in
if(value.startLocation.x < 20 && value.translation.width > 100) {
self.shouldShowSpotifyAuth = false
}
})
)
}
php函数，如下所示：
in_array()代码进入您的活动子主题（或活动主题）的function.php文件中，已经过测试并且可以正常工作。
