我在stackoverflow上发现了这段代码，它满足了我的需要，只不过我在购物车中添加了2种产品后需要为每种产品应用-5€折扣。
示例：
依此类推...
add_action('woocommerce_cart_calculate_fees' , 'custom_discount', 10, 1);
function custom_discount( $cart ){
if ( is_admin() && ! defined( 'DOING_AJAX' ) && ! is_user_logged_in() )
// if ( is_admin() && ! defined( 'DOING_AJAX' ) )
return;
// Only when there is 2 or more items in cart
if( $cart->get_cart_contents_count() >= 2):
// Initialising variable
$is_on_sale = false;
// Iterating through each item in cart
foreach( $cart->get_cart() as $cart_item ){
// Getting an instance of the product object
$product = $cart_item['data'];
// If a cart item is on sale, $is_on_sale is true and we stop the loop
if($product->is_on_sale()){
$is_on_sale = true;
break;
}
}
## Discount calculation ##
// fixed reduction price
$reduction = 5;
## Applied discount (no products on sale) ##
if(!$is_on_sale )
$cart->add_fee( '-5€ à partir du 2ème article commandé', -$reduction);
endif;
}
感谢您的任何帮助。
你是如此亲密。您知道购物车$cart->get_cart_contents_count()中的项目数量，并且希望从第一个产品开始就开始折扣。
替换$reduction = 5;
带有此$reduction = 5*($cart->get_cart_contents_count() - 1);
您的完整代码应如下所示：
add_action('woocommerce_cart_calculate_fees' , 'custom_discount', 10, 1);
function custom_discount( $cart ){
if ( is_admin() && ! defined( 'DOING_AJAX' ) && ! is_user_logged_in() )
// if ( is_admin() && ! defined( 'DOING_AJAX' ) )
return;
// Only when there is 2 or more items in cart
if( $cart->get_cart_contents_count() >= 2):
// Initialising variable
$is_on_sale = false;
// Iterating through each item in cart
foreach( $cart->get_cart() as $cart_item ){
// Getting an instance of the product object
$product = $cart_item['data'];
// If a cart item is on sale, $is_on_sale is true and we stop the loop
if($product->is_on_sale()){
$is_on_sale = true;
break;
}
}
## Discount calculation ##
// fixed reduction price
$reduction = 5*($cart->get_cart_contents_count() - 1);
## Applied discount (no products on sale) ##
if(!$is_on_sale )
$cart->add_fee( '-5€ à partir du 2ème article commandé', -$reduction);
endif;
}
您最好使用以下内容，该内容将仅计算常规商品（不包括“正在销售”的商品），并将根据从第二项开始的特定数量应用折扣：
add_action('woocommerce_cart_calculate_fees' , 'progressive_fixed_discount', 10, 1);
function progressive_fixed_discount( $cart ){
if ( is_admin() && ! defined( 'DOING_AJAX' ) && ! is_user_logged_in() )
// if ( is_admin() && ! defined( 'DOING_AJAX' ) )
return;
// Initialising variable
$regular_items_count = -1;
// Iterating through each item in cart
foreach( $cart->get_cart() as $cart_item ){
// Count only on regular items (not "on sale" items)
if( ! $cart_item['data']->is_on_sale() ){
$regular_items_count += $cart_item['quantity'];
}
}
// Only for regular items starting on the 2nd item (not "on sale" items)
if ( $regular_items_count > 0 ) {
// Progressive fixed discount calculation on regular items only
$discount = 5 * $regular_items_count;
// Apply a discount for "on sale" items only
$cart->add_fee( __("-5€ à partir du 2ème article commandé", "woocommerce"), -$discount );
}
}
