如何计算 WooCommerce 购物车中添加的产品 ID 的额外费用
How to sum the additional fees of added product ID's in WooCommerce cart
我正在使用 答案代码(第 2 部分)。此代码用于向使用其 ID 描述的产品添加额外费用。
我已替换的现有答案中:
// Settings
$settings = array(
array(
'product_id' => 30,
'amount' => 5,
'name' => __( 'Additional service fee', 'woocommerce' ),
),
array(
'product_id' => 813,
'amount' => 10,
'name' => __( 'Packing fee', 'woocommerce' ),
),
array(
'product_id' => 815,
'amount' => 15,
'name' => __( 'Another fee', 'woocommerce' ),
),
);
有
// Settings
$settings = array(
array(
'product_id' => __(123, 456, 789),
'amount' => 10,
'name' => __( 'Additional service fee', 'woocommerce' ),
),
array(
'product_id' => __(987, 654, 321),
'amount' => 20,
'name' => __( 'Additiona packing fee', 'woocommerce' ),
),
array(
'product_id' => __(445, 556, 555),
'amount' => 30,
'name' => __( 'Additinal specific fee', 'woocommerce' ),
),
);
目前,如果我添加两个属于同一“附加费”类别的产品,例如,“'Additional service fee'”只显示一次金额,不计算在内。
我的问题是如何更改代码,以便通过添加属于同一“附加费用”类别的多个产品来考虑该类别的费用总和。
__() WordPress 函数检索翻译,因此与添加多个产品 ID 无关。相反,您可以将多个产品 ID 添加为一个数组。
注意: total_amount
设置用作跟踪总量的计数器,因此不应更改!
注意:我添加了额外的代码,该代码也考虑了产品数量。如果不适用。只需删除 $quantity = $cart_item['quantity'];
并将 $setting['amount'] * $quantity;
更改为 $setting['amount'];
所以你得到:
function action_woocommerce_cart_calculate_fees( $cart ) {
if ( is_admin() && ! defined( 'DOING_AJAX' ) )
return;
// Settings (multiple settings arrays can be added/removed if desired)
$settings = array(
array(
'product_id' => array( 30, 813, 815 ),
'amount' => 5,
'name' => __( 'Additional service fee', 'woocommerce' ),
'total_amount' => 0,
),
array(
'product_id' => array( 817, 819, 820 ),
'amount' => 25,
'name' => __( 'Packing fee', 'woocommerce' ),
'total_amount' => 0,
),
array(
'product_id' => array( 825 ),
'amount' => 100,
'name' => __( 'Another fee', 'woocommerce' ),
'total_amount' => 0,
),
);
// Loop through cart contents
foreach ( $cart->get_cart_contents() as $cart_item ) {
// Get product id
$product_id = $cart_item['product_id'];
// Get quantity
$quantity = $cart_item['quantity'];
// Loop trough settings array (determine total amount)
foreach ( $settings as $key => $setting ) {
// Search for the product ID
if ( in_array( $product_id, $settings[$key]['product_id'] ) ) {
// Addition
$settings[$key]['total_amount'] += $setting['amount'] * $quantity;
}
}
}
// Loop trough settings array (output)
foreach ( $settings as $setting ) {
// Greater than 0
if ( $setting['total_amount'] > 0 ) {
// Add fee
$cart->add_fee( $setting['name'], $setting['total_amount'], false );
}
}
}
add_action( 'woocommerce_cart_calculate_fees', 'action_woocommerce_cart_calculate_fees', 10, 1 );
