[英]WooCommerce specific coupon discount based on product category
I've a problem with this code to apply different percentage of discount to product in different category我对此代码有问题,无法对不同类别的产品应用不同百分比的折扣
The function work but is execute n times where n depends on the number of products in cart function 工作但执行 n 次,其中 n 取决于购物车中的产品数量
add_filter( 'woocommerce_coupon_get_discount_amount', 'alter_shop_coupon_data', 1, 5 );
function alter_shop_coupon_data( $discount, $discounting_amount, $cart_item, $single, $instance ){
$coupons = WC()->cart->get_coupons();
$cart_items = WC()->cart->get_cart();
foreach ( $coupons as $code => $coupon ) {
if ( $coupon->discount_type == 'percent' && $coupon->code == 'newsite' ) {
foreach ($cart_items as $cart_item){
$product_id = $cart_item['data']->id;
if( has_term( 'cat1', 'product_cat', $product_id ) ){
$quantity = $cart_item['quantity'];
$price = $cart_item['data']->price;
$discount_20 = 0.2 * ($quantity * $price); // 20%
}else{
$quantity = $cart_item['quantity'];
$price = $cart_item['data']->price;
$discount_10 = 0.1 * ($quantity * $price); //10%
}
}
}
}
$discounting_amount = ($discount_20 + $discount_10);
return $discounting_amount;
}
Since WooCommerce 3, there are many mistakes in your code… Also the $cart_item
argument is included in the function, so you don't need to loop through cart items.由于 WooCommerce 3,您的代码中存在许多错误......此外, $cart_item
参数包含在 function 中,因此您无需遍历购物车项目。
Also note that $coupon->is_type('percent')
(coupon type) is not needed as you target a specific coupon in your code: $coupon->get_code() == 'newsite
.另请注意,当您在代码中定位特定优惠券时,不需要$coupon->is_type('percent')
(优惠券类型) : $coupon->get_code() == 'newsite
。
Try the following:尝试以下操作:
add_filter( 'woocommerce_coupon_get_discount_amount', 'alter_shop_coupon_data', 100, 5 );
function alter_shop_coupon_data( $discount, $discounting_amount, $cart_item, $single, $instance ){
// Loop through applied WC_Coupon objects
foreach ( WC()->cart->get_coupons() as $code => $coupon ) {
if ( $coupon->is_type('percent') && $coupon->get_code() == 'newsite' ) {
$discount = $cart_item['data']->get_price() * $cart_item['quantity'];
if( has_term( 'cat1', 'product_cat', $cart_item['product_id'] ) ){
$discount *= 0.2; // 20%
}else{
$discount *= 0.1; // 10%
}
}
}
return $discount;
}
Code goes in functions.php file of the active child theme (or active theme).代码进入活动子主题(或活动主题)的functions.php文件。 It should better work.它应该更好地工作。
