以下代码将为每3件商品(3、6、9…) 增加统一费用运送方式的费用.
The following code will add an additional cost to flat rate shipping method each 3 items (3, 6, 9 …).
您需要用简单的初始费用代替您的公式来更改运输费用.
You will need to change your shipping cost with a simple initial cost instead of your formula.
您可能需要启用调试模式"，在送货选项"下的常规送货设置下，标签，以禁用临时运送缓存.
You may have to "Enable debug mode" in general shipping settings under "Shipping options" tab, to disable temporarily shipping caches.
代码(您将在其中设置额外的运费):
add_filter('woocommerce_package_rates', 'shipping_additional_cost_each_three_items', 10, 2);
function shipping_additional_cost_each_three_items( $rates, $package ){
if ( is_admin() && ! defined( 'DOING_AJAX' ) )
return $rates;
// HERE set your additional shipping cost
$additional_cost = 1.25;
$items_count = 0; // Initializing
$each_items = 3; // Number of items (for additional cost)
// Loop through cart items for the current shipping package
foreach( $package['contents'] as $cart_item ) {
$items_count = += $cart_item['quantity']; // Count cart items for current shipping package
}
if ( $items_count >= $each_items ) {
// Loop through the shipping taxes array
foreach ( $rates as $rate_key => $rate ){
// Targetting "flat rate"
if( 'flat_rate' === $rate->method_id ){
$initial_cost = $new_cost = $rate->cost;
$has_taxes = false; // Initializing
$taxes = array(); // Initializing
// Adding to cost the additional cost each 3 items (3, 6, 9 …)
for($i = 0; $i <= $items_count; $i+ = $each_items){
$new_cost += $additional_cost;
}
$rates[$rate_key]->cost = $new_cost; // Set the new cost
// Taxes rate cost (if any) - Loop through taxes array (as they can be many)
foreach ($rate->taxes as $key => $tax){
if( $tax > 0 ){
// Get the initial tax cost
$initial_tax_cost = $new_tax_cost = $tax;
// Get the tax rate conversion
$tax_rate = $initial_tax_cost / $initial_cost;
// Set the new tax cost
$taxes[$key] = $new_cost * $tax_rate;
$has_taxes = true; // Enabling tax changes
}
}
// set array of shipping tax cost
if( $has_taxes ) {
$rates[$rate_key]->taxes = $taxes;
}
}
}
}
return $rates;
}
代码进入您的活动子主题(或活动主题)的function.php文件中.经过测试，可以正常工作.
Code goes in function.php file of your active child theme (or active theme). Tested and works.
不要忘记禁用启用调试模式".运输设置中的选项.
Don't forget to disable "Enable debug mode" option in shipping settings.
基于您的第二条评论的答案:
您将替换此块:
// Adding to cost the additional cost each 3 items (3, 6, 9 …)
for($i = 0; $i <= $items_count; $i += $each_items){
$new_cost += $additional_cost;
}
通过以下方式:
// Adding to cost an additional fixed cost for the 2nd item
if($items_count >= 2){
$new_cost += 6.21;
}
// Adding to cost the additional cost each 3 items (3, 6, 9 …)
for($i = 0; $i <= $items_count; $i += $each_items){
$new_cost += $additional_cost;
}
