Woocommerce -按订单总额计算的计算器运输成本，但没有优惠券。

Question

首先，我不是一个专业的开发人员，对于一个客户，我们有以下要求。目前，在Woocommerce，运输成本是根据订单总额(费用percent="8") -订单金额的8%以上计算的。

客户现在想要的是，如果使用优惠券，运输成本应根据原始金额计算，而不是按新的优惠券金额计算。

有办法顺利解决吗？

谢谢！朱利安

Answer 1

您需要使用woocommerce_package_rates过滤器钩子，其中得到的总购物车数量，除了优惠券金额和改变每一个运费循环的shiiping成本。如果你有什么问题告诉我。

add_filter( 'woocommerce_package_rates', 'custom_shipping_costs', 10, 2 );
function custom_shipping_costs( $rates, $package ) {
    $carttotal = WC()->cart->get_cart_subtotal();
    
    $taxes = array();
    foreach ($rates[$rate_key]->taxes as $key => $tax){
        if( $rates[$rate_key]->taxes[$key] > 0 ){
            $taxes[$key] = $carttotal * 0.08;
        }
    }
    $rates[$rate_key]->taxes = $taxes;
}

以下是我的解决方案：

1.

add_filter( 'woocommerce_package_rates', 'custom_shipping_costs', 20, 2 );
function custom_shipping_costs( $rates, $package ) {
global $woocommerce;
    
    if (!empty(WC()->cart->applied_coupons)){
    
    $totalfees = WC()->cart->get_fees();  //$order->get_total_fees();
    $producttotal = WC()->cart->subtotal; // $order->get_subtotal();
    $total = (float)$totalfees + (float)$producttotal;
    
   // New shipping cost (can be calculated)
    $new_cost = $total * .08;
    $tax_rate = array();

    foreach( $rates as $rate_key => $rate ){
        // Excluding free shipping methods
        if( $rate->method_id != 'free_shipping'){

            // Set rate cost
            $rates[$rate_key]->cost = $new_cost;

            // Set taxes rate cost (if enabled)
            $taxes = array();
            foreach ($rates[$rate_key]->taxes as $key => $tax){
                if( $rates[$rate_key]->taxes[$key] > 0 )
                    $taxes[$key] = $new_cost * $tax_rate;
            }
            $rates[$rate_key]->taxes = $taxes;

        }
    }
    
    return $rates;
}
}

1. ​

if(!empty( $order->get_used_coupons() )) {

    $totalfees = $order->get_total_fees();
    $producttotal = $order->get_subtotal();
    $total = (float)$totalfees + (float)$producttotal;
    

// Get the customer country code
$country_code = $order->get_shipping_country();

// Set the array for tax calculations
$calculate_tax_for = array(
    'country' => $country_code,
    'state' => '', // Can be set (optional)
    'postcode' => '', // Can be set (optional)
    'city' => '', // Can be set (optional)
);

// Optionally, set a total shipping amount
$new_ship_price =  $total * .08;

// Get a new instance of the WC_Order_Item_Shipping Object
$item = new WC_Order_Item_Shipping();

$item->set_method_title( "Flat rate" );
$item->set_method_id( "flat_rate:14" ); // set an existing Shipping method rate ID
$item->set_total( $new_ship_price ); // (optional)
$item->calculate_taxes($calculate_tax_for);

$order->add_item( $item );

$order->calculate_totals();

$order->update_status('on-hold');

// $order->save(); // If you don't update the order status
}
