WooCommerce的最小定制运输成本需要进行小计和税务计算

Question

我在WooCommerce中设置了一些启用应税选项的运输方法。如果花费超过X金额，我使用此代码设置不同的运输成本：

// Extra discount on shipping for orders of values of above 150 or 100.
function custom_adjust_shipping_rate( $rates ) {
$cart_subtotal = WC()->cart->subtotal;
// Check if the subtotal is greater than value specified
if ( $cart_subtotal >= 29.99 ) {
// Loop through each shipping rate
foreach ( $rates as $rate ) {
// Store the previous cost in $cost
$cost = $rate->cost;
// Adjust the cost as needed
// original shipping greater than 6 discount by 5 
if ( $cost == 7.38 ) {
// discount rate by 5
$rate->cost = $cost - 2.54;
}
// Optional discount for other shipping rates 
if ( $cost == 4.10 ) {
$rate->cost = $cost - 5;
}
}
}
return $rates;
}
add_filter( 'woocommerce_package_rates', 'custom_adjust_shipping_rate', 10 );

但问题在于税收计算。我的代码不处理税收。

如何从海关运费中调整税款？

如何在成本计算中启用税款？

欢迎提出任何建议。

要在代码中启用运费税计算，请使用以下重新访问的代码：

add_filter( 'woocommerce_package_rates', 'adjust_shipping_rates_cost', 10, 2 );
function adjust_shipping_rates_cost( $rates, $package ) {
$min_subtotal  = 30; // Set min subtotal
$cart_subtotal = 0; // Initializing

// Loop through cart items to get items total for the current shipping package 
foreach( $package['contents'] as $item ) {
$cart_subtotal += $item['line_subtotal'] + $item['line_subtotal_tax'];
// $cart_subtotal += $item['line_subtotal']; // Or without taxes
}
// Check if the subtotal is greater than specified value
if ( $cart_subtotal < $min_subtotal ) {
return $rates; // Exit
}
// Loop through shipping rates
foreach ( $rates as $rate_key => $rate ) {
$has_taxes = false; // Initializing
$taxes     = array(); // Initializing
$new_cost = $initial_cost = $rate->cost; // grab initial cost
if ( $initial_cost == 7.38 ) {
$new_cost -= 2.54;
} elseif ( $initial_cost == 4.10 ) {
$new_cost -= 5;
}
$rates[$rate_key]->cost = $new_cost; // Set new rate cost
// Loop through taxes array (change taxes rate cost if enabled)
foreach ($rate->taxes as $key => $tax){
if( $tax > 0 ){
// Get the tax rate conversion
$tax_rate    = $tax / $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。它应该起作用。
