我正在尝试对购物车中的所有商品应用TOTAL CART折扣,具体取决于添加的商品数量.我已经从answer here中获取并修改了代码示例,并使大部分逻辑工作.
但是我不能让它适用于下面描述的两种情况.它还仅将规则应用于购物车中的单个项目.不是整个购物车.
场景：
>如果购物车中没有商品在9-12之间,则对所有商品应用5％折扣.
>如果购物车中没有商品在13-16之间,则对所有商品应用10％折扣.
>折扣不应该叠加.例如购物车中有12件商品,可享5％折扣……添加13件商品,可享受5％优惠并享受10％优惠.
码：
add_filter('woocommerce_add_cart_item_data', 'add_items_default_price_as_custom_data', 20, 3 );
function add_items_default_price_as_custom_data( $cart_item_data, $product_id, $variation_id ){
$product_id = $variation_id > 0 ? $variation_id : $product_id;
## ----- YOUR SETTING ----- ##
$discount_percentage = 5; // Discount (5%)
// The WC_Product Object
$product = wc_get_product($product_id);
// Only for non on sale products
if( ! $product->is_on_sale() ){
$price = (float) $product->get_price();
// Set the Product default base price as custom cart item data
$cart_item_data['base_price'] = $price;
// Set the Product discounted price as custom cart item data
$cart_item_data['new_price'] = $price * (100 - $discount_percentage) / 100;
// Set the percentage as custom cart item data
$cart_item_data['percentage'] = $discount_percentage;
}
return $cart_item_data;
}
// Display the product original price
add_filter('woocommerce_cart_item_price', 'display_cart_items_default_price', 20, 3 );
function display_cart_items_default_price( $product_price, $cart_item, $cart_item_key ){

}
// Display the product name with the discount percentage
add_filter( 'woocommerce_cart_item_name', 'append_percetage_to_item_name', 20, 3 );
function append_percetage_to_item_name( $product_name, $cart_item, $cart_item_key ){

## ----- YOUR SETTING ----- ##
$balanced_qty = 9; // Targeted quantity
$upper_balanced_qty = 12; // Max quantity limit
// Loop through cart items
foreach ( $cart->get_cart() as $cart_item ) {
// For item quantity between 9 and 12
if( ($cart_item['quantity'] >= $balanced_qty && isset($cart_item['new_price']) && ($cart_item['quantity'] <= $upper_balanced_qty) ) ){
// Set cart item discounted price
$cart_item['data']->set_price($cart_item['new_price']);
}
}
}
解决方法:
您可以按购物车商品数量或全球购物车商品数量来执行此操作：
1)按购物车数量：
// Utility function that give the discount percentage based on quantity argument
function get_discount_percent( $quantity ){
if( $quantity < 9 )
$percent = 0; // 0 % ( quantity from 1 to 8 )
elseif( $quantity >= 9 && $quantity < 13 )
$percent = 5; // 5 % ( quantity from 9 to 12 )
else
$percent = 10; // 10 % ( quantity up to 13 )
return $percent;
}
add_filter('woocommerce_add_cart_item_data', 'add_items_default_price_as_custom_data', 20, 3 );
function add_items_default_price_as_custom_data( $cart_item_data, $product_id, $variation_id ){
$product_id = $variation_id > 0 ? $variation_id : $product_id;
## ----- YOUR SETTING ----- ##
$percent_1 = 5; // Discount (5%)
$percent_2 = 10; // Discount (10%)
// The WC_Product Object
$product = wc_get_product($product_id);
$price = (float) $product->get_price();
// Set the Product default base price as custom cart item data
$cart_item_data['discount'][0] = $price;
// Set the Product discounted price of 5% as custom cart item data
$cart_item_data['discount'][$percent_1] = $price * (100 - $percent_1) / 100;
// Set the Product discounted price of 10% as custom cart item data
$cart_item_data['discount'][$percent_2] = $price * (100 - $percent_2) / 100;
return $cart_item_data;
}
// Display the product original price
add_filter('woocommerce_cart_item_price', 'display_cart_items_default_price', 20, 3 );
function display_cart_items_default_price( $product_price, $cart_item, $cart_item_key ){
if( isset($cart_item['discount'][0]) ) {
$product = $cart_item['data'];
$product_price = wc_price( wc_get_price_to_display( $product, array( 'price' => $cart_item['discount'][0] ) ) );
}
return $product_price;
}
// Display the product name with the discount percentage
add_filter( 'woocommerce_cart_item_name', 'append_percetage_to_item_name', 20, 3 );
function append_percetage_to_item_name( $product_name, $cart_item, $cart_item_key ){
// get the percent based on quantity
$percent = get_discount_percent($cart_item['quantity']);
if( isset($cart_item['discount'][$percent]) && isset($cart_item['discount'][0]) ) {
if( $cart_item['data']->get_price() != $cart_item['discount'][0] )
$product_name .= ' <em>(' . $percent . '% discounted)</em>';
}
return $product_name;
}
add_action( 'woocommerce_before_calculate_totals', 'set_custom_discount_cart_item_price', 25, 1 );
function set_custom_discount_cart_item_price( $cart ) {
if ( is_admin() && ! defined( 'DOING_AJAX' ) )
return;
if ( did_action( 'woocommerce_before_calculate_totals' ) >= 2 )
return;
foreach( $cart->get_cart() as $cart_item ){
// get the percent based on quantity
$percentage = get_discount_percent($cart_item['quantity']);
// For items non on sale set a discount based on quantity as defined in
if( $percentage != 0 && isset($cart_item['discount'][$percentage]) && ! $cart_item['data']->is_on_sale() ) {
$cart_item['data']->set_price($cart_item['discount'][$percentage]);
}
}
}

Here below, in this example, the third item is on sale, so the real count is
10 + 1 = 11items and then the discount for11items is5%:07001
