Woocommerce中特定产品的购物车批量折扣 [英] Cart bulk quantity discount for specific products in Woocommerce
问题描述
在woocommerce中,我尝试仅针对特定产品ID进行自定义购物车商品数量折扣.这是我正在尝试做的事情:
如果客户将特定产品添加到购物车中,我想保留第一件商品的原始价格,并为每增加一个商品设置折扣的自定义价格.
In woocommerce I am trying to make a custom cart item quantity discount for a specific product ID only. This is what I am trying to do:
If a customer add to cart a specific product, I would like to keep the original price for the first item and set a discounted custom price for each additional item quantity.
例如:
- 产品有效价格为40(我们为第一个数量项目保留此价格)
- 对于不超过2个(附加项目数量)的数量,价格为12.
因此,如果客户添加了数量为5的产品,那么价格将为:
40 + 12 + 12 + 12 + 12 = 88
So if customer add the product with a quantity 5 items, then the price will be:
40 + 12 + 12 + 12 + 12 = 88
所以我尝试稍微更改此答案代码:
Woocommerce 3中的购物车数量渐进百分比折扣
So I tried changing this answer code a bit:
Cart item quantity progressive percentage discount in Woocommerce 3
但是无法使其正常工作.
But couldn't make it work correctly.
感谢您的帮助.
推荐答案
对于您的情况,请使用以下内容:
For your case use the following instead:
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 ){
## Your settings her below ##
$product_ids = array(37); // <=== Your specific product(s) ID(s) in the array
$discounted_price = 12; // <=== The specific product discounted price
// The WC_Product Object
$product = wc_get_product($variation_id > 0 ? $variation_id : $product_id);
if( array_intersect( $product_ids, array($product_id, $variation_id) ) && ! $product->is_on_sale() ){
// We set the Product discounted price
$cart_item_data['pricing']['discounted'] = $discounted_price;
// Set the Product default base price as custom cart item data
$cart_item_data['pricing']['active'] = $product->get_price();
}
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['pricing']['active']) && $cart_item['quantity'] > 1 ) {
$product_price = wc_price( wc_get_price_to_display( $cart_item['data'], array( 'price' => $cart_item['pricing']['active'] ) ) );
}
return $product_price;
}
// Display the product name with the a custom "discount" label
add_filter( 'woocommerce_cart_item_name', 'append_custom_label_to_item_name', 20, 3 );
function append_custom_label_to_item_name( $product_name, $cart_item, $cart_item_key ){
if( isset($cart_item['pricing']['discounted']) && $cart_item['data']->get_price() != $cart_item['pricing']['discounted'] ) {
$discounted_price = (float) $cart_item['pricing']['discounted'];
$default_price = (float) $cart_item['pricing']['active'];
$quantity = (int) $cart_item['quantity'];
// Calculate new product price
$new_price = ($default_price + ($discounted_price * ($quantity - 1))) / $quantity;
// Get the discount percentage (if needed)
$percent = 100 - ($new_price / $default_price * 100);
$product_name .= ' <em>(' . __('quantity discounted', 'woocommerce') . ')</em>';
}
return $product_name;
}
// Set the new discounted 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;
foreach( $cart->get_cart() as $cart_item ){
// For items non on sale set a discount based on quantity
if( isset($cart_item['pricing']['discounted']) && $cart_item['quantity'] > 1 ) {
$discounted_price = (float) $cart_item['pricing']['discounted'];
$default_price = (float) $cart_item['pricing']['active'];
$quantity = (int) $cart_item['quantity'];
// Calculate new product price
$new_price = ($default_price + ($discounted_price * ($quantity - 1))) / $quantity;
// Set cart item calculated price
$cart_item['data']->set_price($new_price);
}
}
}
代码进入您的活动子主题(或活动主题)的function.php文件中.经过测试,可以正常工作.
Code goes in function.php file of your active child theme (or active theme). Tested and works.
