解决方案
您可以按购物车商品数量或根据购物车商品数量全局进行:
1) 按购物车商品数量:
//根据数量参数给出折扣百分比的实用函数函数 get_discount_percent( $quantity ){如果( $数量 <9 )$% = 0;//0 % (数量从 1 到 8 )elseif( $quantity >= 9 && $quantity <13 )$% = 5;//5 % (数量从 9 到 12 )别的$% = 10;//10 % ( 数量最多 13 )返回 $percent;}add_filter('woocommerce_add_cart_item_data', 'add_items_default_price_as_custom_data', 20, 3);函数 add_items_default_price_as_custom_data( $cart_item_data, $product_id, $variation_id ){$product_id = $variation_id >0 ?$variation_id : $product_id;## ----- 您的设置 ----- ##$percent_1 = 5;//折扣 (5%)$percent_2 = 10;//折扣 (10%)//WC_Product 对象$product = wc_get_product($product_id);$price = (float) $product->get_price();//将产品默认基本价格设置为自定义购物车项目数据$cart_item_data['discount'][0] = $price;//将产品折扣价设置为 5% 作为自定义购物车项目数据$cart_item_data['discount'][$percent_1] = $price * (100 - $percent_1)/100;//将产品折扣价设置为 10% 作为自定义购物车项目数据$cart_item_data['discount'][$percent_2] = $price * (100 - $percent_2)/100;返回 $cart_item_data;}//显示产品原价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] ) );}返回 $product_price;}//显示带有折扣百分比的产品名称add_filter('woocommerce_cart_item_name', 'append_percetage_to_item_name', 20, 3);函数 append_percetage_to_item_name( $product_name, $cart_item, $cart_item_key ){//获取基于数量的百分比$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 .= ' (' . $percent .

2) 全球范围内的购物车商品数量 (对于非特价商品):
//根据数量参数给出折扣百分比的实用函数函数 get_discount_percent( $quantity ){如果( $数量 <9 )$% = 0;//0 % (数量从 1 到 8 )elseif( $quantity >= 9 && $quantity <13 )$% = 5;//5 % (数量从 9 到 12 )别的$% = 10;//10 % ( 数量最多 13 )返回 $percent;}//计算未销售的购物车商品的实用函数函数 get_non_on_sale_cart_items_count(){$items_count = 0;foreach(WC()->cart->get_cart() 作为 $cart_item ){if(!$cart_item['data']->is_on_sale()){$items_count += $cart_item['数量'];}}返回 $items_count;}add_filter('woocommerce_add_cart_item_data', 'add_items_default_price_as_custom_data', 20, 3);函数 add_items_default_price_as_custom_data( $cart_item_data, $product_id, $variation_id ){$product_id = $variation_id >0 ?$variation_id : $product_id;## ----- 您的设置 ----- ##$percent_1 = 5;//折扣 (5%)$percent_2 = 10;//折扣 (10%)//WC_Product 对象$product = wc_get_product($product_id);$price = (float) $product->get_price();//将产品默认基本价格设置为自定义购物车项目数据$cart_item_data['discount'][0] = $price;//将产品折扣价设置为 5% 作为自定义购物车项目数据$cart_item_data['discount'][$percent_1] = $price * (100 - $percent_1)/100;//将产品折扣价设置为 10% 作为自定义购物车项目数据$cart_item_data['discount'][$percent_2] = $price * (100 - $percent_2)/100;返回 $cart_item_data;}//显示产品原价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] ) );}返回 $product_price;}//显示带有折扣百分比的产品名称add_filter('woocommerce_cart_item_name', 'append_percetage_to_item_name', 20, 3);函数 append_percetage_to_item_name( $product_name, $cart_item, $cart_item_key ){//获取购物车商品数量$items_count = get_non_on_sale_cart_items_count();//获取基于数量的百分比$percent = get_discount_percent($items_count);if( isset($cart_item['discount'][$percent]) && isset($cart_item['discount'][0]) ) {if( $cart_item['data']->get_price() != $cart_item['discount'][0] )$product_name .= ' (' . $percent .

I am trying to apply a TOTAL CART discount to all the items in the cart, depending on the quantity of items added. I have taken and modified the code example from answer here and got most of the logic working.
I cannot however get it working for two scenarios described below. It also only applies the rule to a single item in the cart. Not the entire cart.
Scenario:
- If no of items in the cart are between 9-12, Apply 5% Discount to all items.
- If no of items in the cart are between 13-16, Apply 10% Discount to all items.
- The discount's should not stack. e.g. when 12 items in cart, apply 5% discount...when 13 items added, remove 5% discount and apply 10% discount.
Code:
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, $cart_item_key ){
if( isset($cart_item['base_price']) ) {
$product = $cart_item['data'];
$product_price = wc_price( wc_get_price_to_display( $product, array( 'price' => $cart_item['base_price'] ) ) );
}
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, $cart_item_key ){
if( isset($cart_item['percentage']) && isset($cart_item['base_price']) ) {
if( $cart_item['data']->get_price() != $cart_item['base_price'] )
$product_name .= ' <em>(' . $cart_item['percentage'] . '% discounted)</em>';
}
return $product_name;
}
add_action( 'woocommerce_before_calculate_totals', 'custom_discounted_cart_item_price', 20, 1 );
function custom_discounted_cart_item_price( $cart ) {
## ----- 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']);
}
}
}
解决方案
You can do it by cart item quantity or globally based on cart items count:
1) By cart item quantity:
// 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]);
}
}
}
Code goes in function.php file of your active child theme (or active theme). Tested and works.
2) Globally on cart item count (for non on sale products):
// 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;
}
// Utility function that count cart items that are not on sale
function get_non_on_sale_cart_items_count(){
$items_count = 0;
foreach( WC()->cart->get_cart() as $cart_item ){
if( ! $cart_item['data']->is_on_sale() ){
$items_count += $cart_item['quantity'];
}
}
return $items_count;
}
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 cart items count
$items_count = get_non_on_sale_cart_items_count();
// get the percent based on quantity
$percent = get_discount_percent($items_count);
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>';
elseif ( $cart_item['data']->is_on_sale() && $percent != 0 ){
$product_name .= ' <em>(Item on sale)</em>';
}
}
return $product_name;
}
// Change cart item price
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;
// Get cart items count
$items_count = get_non_on_sale_cart_items_count();
// get the percent based on quantity
$percentage = get_discount_percent($items_count);
foreach( $cart->get_cart() as $cart_item ){
// 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]);
}
}
}
Code goes in function.php file of your active child theme (or active theme). Tested and works.
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%:
