在 WooCommerce 中插入一个自定义总计，不包括购物车上的产品成本行和结帐总计 [英] Insert a custom total excluding products cost row on cart and checkout totals in WooCommerce

问题描述

我可以使用 在 Woocommerce 中的购物车和结帐总额中插入自定义总行 应答代码.(虽然我需要在底部添加我的)但我找不到或弄清楚如何计算我需要的总数.

I can add an extra row to the checkout totals table with Insert a custom total row on cart and checkout totals in Woocommerce answer code. (albeit I need to add mine at the bottom) but I can't find or figure out how to calculate the total that I need.

我需要添加的总数应包括除产品成本之外的所有内容(因此应包括运费、增值税、费用等).

The total I need to add should include everything apart from the product cost (so should include shipping, VAT, fees etc.).

我无法将产品价格更改为零，因为它们用于计算费用.

I can't change the product prices to zero as they're used for fee calculations.

我的代码尝试:

add_action( 'woocommerce_cart_totals_before_shipping', 'display_custom_total', 20 );
add_action( 'woocommerce_review_order_before_shipping', 'display_custom_total', 20 );
function display_custom_total() {
$total_to_pay = 0;
    // Do something here
 
        // The Output
        echo ' <tr class="cart-total-to-pay">
            <th>' . __( "Total to pay", "woocommerce" ) . '</th>
            <td data-title="total-to-pay">' . number_format($total_to_pay, 2) . '</td>
        </tr>';
}

我将如何将其添加到结帐中&购物车页面?

How would I go about adding this to the checkout & cart page?

推荐答案

要在底部显示，使用 woocommerce_cart_totals_after_order_total &woocommerce_review_order_after_order_total 动作挂钩.

To display it at the bottom, use woocommerce_cart_totals_after_order_total & woocommerce_review_order_after_order_total action hook instead.

所以你得到:

function display_custom_total() {
    // Get (sub)total
    $subtotal = WC()->cart->subtotal;
    $total = WC()->cart->total;
    
    // Calculate
    $total_to_pay = $total - $subtotal;
    
    // The Output
    echo ' <tr class="cart-total-to-pay">
        <th>' . __( 'Total to pay', 'woocommerce' ) . '</th>
        <td data-title="total-to-pay">' . wc_price( $total_to_pay ) . '</td>
    </tr>';
}
add_action( 'woocommerce_cart_totals_after_order_total', 'display_custom_total', 20 );
add_action( 'woocommerce_review_order_after_order_total', 'display_custom_total', 20 );
