您的产品名为“可重复使用的湿”似乎是一种可变产品,根据某些产品属性具有多种变体。
因此,在您的情况下,可以通过 2 种不同方式应用折扣。
但首先您需要定义“可重复使用的湿”数量包装中涉及的相关产品属性 SLUG 以及“包装的”相关术语 NAME 值5" 在代码中。
如果设置不正确,代码将无法运行。
1) 更改相关商品价格 (最好的方法):
在这里,当购物车中有 2 件或更多相关商品时,我们将折扣单价设置为 9(18 / 2 = 9)。
add_action( 'woocommerce_before_calculate_totals', 'conditionally_set_discounted_price', 30, 1 );
function conditionally_set_discounted_price( $cart ) {
if ( is_admin() && ! defined( 'DOING_AJAX' ) )
return;
if ( did_action( 'woocommerce_before_calculate_totals' ) >= 2 )
return;
// HERE your product attribute slug for "Reusable wet" (without "pa_")
$product_attr = 'reusable-wet';
$product_attr = 'color';
// HERE set the corresponding (value) term NAME for "5 Reusable wet"
$term_slug = '5 reusable wet';
$term_slug = 'Black';
// HERE set the discounted price for each cart item with "5 Reusable wet" when they are 2 or more
$discounted_price = 9; // (18 / 2 = 9)
$five_rw_count = 0; // Initializing variable
// 1st Loop: count cart items with "5 Reusable wet"
foreach ( $cart->get_cart() as $cart_item ){
if( $cart_item['data']->get_attribute( $product_attr ) == $term_slug ){
$five_rw_count += $cart_item['quantity'];
}
}
// Continue if there is at least 2 units of "5 Reusable wet"
if( $five_rw_count < 2 ) return; // Exit
// 2nd Loop: set the discounted price for cart items with "5 Reusable wet"
foreach ( $cart->get_cart() as $cart_item ){
if( $cart_item['data']->get_attribute( $product_attr ) == $term_slug ){
$cart_item['data']->set_price($discounted_price); // Set the discounted price
}
}
}

2) 优惠券方式 (由于许多逻辑原因不是很方便):
您必须在此处设置优惠券代码。此优惠券设置应如下所示:
您将在“产品”字段中设置所有相关产品变体。
完成后,您将在以下代码中设置优惠券名称(小写):
add_action( 'woocommerce_before_calculate_totals', 'conditionally_auto_add_coupon', 30, 1 );
function conditionally_auto_add_coupon( $cart ) {
if ( is_admin() && !defined('DOING_AJAX') ) return; // Exit
// HERE your product attribute slug for "Reusable wet" (without "pa_")
$product_attr = 'reusable-wet';
// HERE set the corresponding (value) term NAME for "5 Reusable wet"
$term_slug = '5 reusable wet';
// HERE set the coupon code (in lowercase)
$coupon_code = 'multiplefive';
$five_rw_count = 0; // Initializing variable
// 1st Loop: count cart items with "5 Reusable wet"
foreach ( $cart->get_cart() as $cart_item ){
if( $cart_item['data']->get_attribute( $product_attr ) == $term_slug ){
$five_rw_count++; // Increasing count
}
}
// Apply the coupon if there is at least 2 units of "5 Reusable wet"
if ( ! $cart->has_discount( $coupon_code ) && $five_rw_count >= 2 ) {
$cart->add_discount( $coupon_code );
}
// Remove the coupon if there is at less than 2 units of "5 Reusable wet"
elseif ( $cart->has_discount( $coupon_code ) && $five_rw_count < 2 ) {
$cart->remove_coupon( $coupon_code );
}
}
