根据 WooCommerce 中的购物车小计将特定的应税运费成本设置为 0

Question

使用以下代码，当购物车小计达到特定金额（此处为 150波兰兹罗提）：

function override_inpost_cost( $rates, $package ) {
    // Make sure paczkomaty is available
    if ( isset( $rates['easypack_parcel_machines'] ) ) {
        // Current value of the shopping cart
        $cart_subtotal = WC()->cart->subtotal;
        // Check if the subtotal is greater than 150pln
        if ( $cart_subtotal >= 150 )    {
            // Set the cost to 0pln
            $rates['easypack_parcel_machines']->cost = 0;

        }
    }
    
    return $rates;
}

add_filter( 'woocommerce_package_rates', 'override_inpost_cost', 10, 2 );

但问题是运费税原始成本仍然存在，即使“easypack_parcel_machines”运输方式费率成本设置为零其原始成本（因为它是应税的）。

如何更改代码，如果“easypack_parcel_machines”运输方式费率设置为 0，税收也将设置为零？

注意：由于购物车可以通过一些插件或一些自定义代码拆分为多个运输包，正确的方法是获取当前运输包中包含的相关购物车项目的小计。 p>

您的代码中缺少的是将税收设置为零，如下所示：

add_filter( 'woocommerce_package_rates', 'override_inpost_shipping_method_cost', 10, 2 );
function override_inpost_shipping_method_cost( $rates, $package ) {
    $targeted_shipping_rate_id = 'easypack_parcel_machines'; // <== Define shipping method rate Id
    
    // Make sure that our shipping rate is available
    if ( isset( $rates[$targeted_shipping_rate_id] ) ) {
        $cart_subtotal_incl_tax = 0; // Initializing

        // Get cart items subtotal for the current shipping package
        foreach( $package['contents'] as $cart_item ) {
            $cart_subtotal_incl_tax += $cart_item['line_subtotal'] + $cart_item['line_subtotal_tax'];
        }
        
        // Check if the subtotal is greater than 150pln
        if ( $cart_subtotal_incl_tax >= 150 )    {
            // Set the cost to 0pln
            $rates[$targeted_shipping_rate_id]->cost = 0;

            $taxes = array(); // Initializing

            // Loop through the shipping method rate taxes array
            foreach( $rates[$targeted_shipping_rate_id]->taxes as $key => $tax_cost ) {
                $taxes[$key] = 0; // Set each tax to Zero
            }

            if ( ! empty($taxes) ) {
                $rates[$targeted_shipping_rate_id]->taxes = $taxes; // Set back "zero" taxes array
            }
        }
    }

    return $rates;
}

代码位于活动子主题（或活动主题）的functions.php 文件中。它应该可以工作。

注意：不要忘记清空您的购物车以刷新运输缓存数据。
