问题描述
根据 Add an additional cost to flat rate shipping each 3 items in Woocommerce 答案代码,我进行了一些更改,为每 2 件商品(而不是每 3 件商品)且仅当有仅来自特定类别的商品(此处为“T 恤”类别)。
这是我的代码尝试:
// add X amount to shipping for every 2 items added to the cart (flat rate only)
add_filter('woocommerce_package_rates','shipping_additional_cost_each_three_items',100,2);
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 = 8.40;
$items_count = WC()->cart->get_cart_contents_count();
// Define/replace here your correct category slug (!)
$product_category = 't-shirts';
$prod_cat = false;
// Going through each item in cart to see if there is anyone of your category
foreach ( WC()->cart->get_cart() as $cart_item ) {
$product_id = $cart_item['product_id'];
if ( has_term( $product_category,'product_cat',$product_id ) ){
$prod_cat = true;
}
}
// Loop through the shipping taxes array
foreach ( $rates as $rate_key => $rate ){
$has_taxes = false;
// Targetting "flat rate"
if( 'flat_rate' === $rate->method_id ){
// Get the initial cost
$initial_cost = $new_cost = $rates[$rate_key]->cost;
// Adding the additional cost if product in T-Shirt category after every 2 items (3,6,9 …)
if ( $prod_cat ) {
for($i = 0; $i <= $items_count; $i+=3){
$new_cost += $additional_cost;
}
}
// Set the new cost
$rates[$rate_key]->cost = $new_cost;
// Taxes rate cost (if enabled)
$taxes = [];
// Loop through the shipping taxes array (as they can be many)
foreach ($rates[$rate_key]->taxes as $key => $tax){
if( $rates[$rate_key]->taxes[$key] > 0 ){
// Get the initial tax cost
$initial_tax_cost = $new_tax_cost = $rates[$rate_key]->taxes[$key];
// 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
}
}
}
if( $has_taxes )
$rates[$rate_key]->taxes = $taxes;
return $rates;
}
}
对于“统一费率”选择的运输方式,当“T 恤”类别的商品在购物车中时,代码就可以正常工作。但如果有不属于“t-shirt”类别的物品,则费率就会消失,并显示没有金额的标题。
有人可以告诉我必须将条件“if category is X”放在哪里才能使该代码起作用?
解决方法
您的代码中有一些错误(例如 return $rates;
应该放在最后一个右括号之前)。请尝试使用以下重新访问的代码:
add_filter('woocommerce_package_rates','shipping_additional_cost_each_three_items',100,2);
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 = 8.40;
$each_items = 2; // Number of items (for additional cost)
// Her set your category(ies) (can be term Ids slugs or names)
$product_categories = array('t-shirts');
$items_cat_count = 0; // Initializing
// Loop through cart items for the current shipping package
foreach( $package['contents'] as $cart_item ) {
if ( ! has_term( $product_categories,'product_cat',$cart_item['product_id'] ) ){
$items_cat_count += $cart_item['quantity']; // Count items from defined category
}
}
if ( $items_cat_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; // Get the initial cost
$has_taxes = false; // Initializing
$taxes = array(); // Initializing
// Adding to cost the additional cost each 2 items (2,4,6 …)
for($i = 0; $i <= $items_cat_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 in the array
$taxes[$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;
}
代码位于活动子主题(或活动主题)的functions.php 文件中。它应该有效。
