在 Woocommerce 订单总计表上显示自定义交付选项

Question

基于“Update fee dynamically based on radio buttons in Woocommerce checkout”回答代码，我已经能够添加应用于客户交付选项的自定义动态费用（带有自定义交付选项选项）。

这是我根据需要调整的工作代码：

add_action( 'woocommerce_cart_calculate_fees', 'add_delivery_fee', 20, 1 );
function add_delivery_fee( $cart ) {
    $domain = 'woocommerce';
    $NipostFST = '2000';
    $NIPOSTSUB = '250';

    if ( is_admin() && ! defined( 'DOING_AJAX' ) )
        return;

    $packing_fee = WC()->session->get( 'chosen_delivery_option' ); // Dynamic delivery fee
    $Dlabel = $packing_fee == 'home_delivery' ? __('To Your Doorstep', $domain) : __('Local Pickup', $domain);
    $weight_of_item = WC()->cart->cart_contents_weight;

    if ( $weight_of_item > 1 ) {
        $nipostFee = $NipostFST + ( ($weight_of_item - 1)*$NIPOSTSUB );
    }elseif ( $weight_of_item == 1 ) {
        $nipostFee = $NipostFST;
    }

    $fee = (isset($weight_of_item)) ? $packing_fee == 'home_delivery' ? $nipostFee : 0.00 : 'Not Available';
    $cart->add_fee( !is_cart() ? __( 'Delivery Fee [ '.$Dlabel.' ]', $domain ) : __( 'Delivery Fee', $domain ), $fee );
}

// Add a custom radio fields for Delivery Option selection
add_action( 'woocommerce_checkout_before_order_review', 'checkout_delivery_fee_addition', 20 );
function checkout_delivery_fee_addition(){
    $domain       = 'woocommerce';
    $weight_of_item = WC()->cart->cart_contents_weight;

    $NipostFST = '2000';
    $NIPOSTSUB = '250';


    if ( $weight_of_item > 1 ) {
        $nipostFee = $NipostFST + ( ($weight_of_item - 1)*$NIPOSTSUB );
    }elseif ( $weight_of_item == 1 ) {
        $nipostFee = $NipostFST;
    }

    echo '<div id="izzycart_checkout_addons"><tr class="deliveryOption-select"><th>' . __('Delivery Method', $domain) . '</th><td>';

    $chosen   = WC()->session->get('chosen_delivery_option');
    $chosen   = empty($chosen) ? WC()->checkout->get_value('radio_delivery_option') : $chosen;
    $chosen   = empty($chosen) ? 'local_pickup' : $chosen;

    // Add a custom checkbox field
    woocommerce_form_field( 'radio_delivery_option', array(
        'type' => 'radio',
        'class' => array( 'form-row-wide delivery_option' ),
        'options' => array(
            'local_pickup' => __('Local Pickup '.wc_price(0.00), $domain),
            'home_delivery' => (!isset($weight_of_item)) ? __('To Your Doorstep <br><span style="color:red">Not Available</span>', $domain) : __('To Your Doorstep '.wc_price($nipostFee), $domain),
        ),
        'default' => $chosen,
    ), $chosen );

    echo '</td></tr></div>';
}

// Display fees with zero amount
add_filter( 'woocommerce_get_order_item_totals_excl_free_fees', '__return_false' );

我的问题：在 Woocommerce 中，我如何在订单详细信息表中的订单接收页面、我的帐户查看订单页面和所有电子邮件通知中显示所选的交付方式。

所以我希望结果看起来像这样：

更新：我添加了 2 个功能，它们将获取订单中选定的交付选项并将其显示在订单详细信息表中的订单接收页面、我的帐户查看订单页面和所有电子邮件通知中：

// Save chosen delivery as order custom meta data
add_action('woocommerce_checkout_create_order', 'save_order_delivery_option', 10, 2 );
function save_order_delivery_option(  $order, $data ) {
    if ( isset($_POST['radio_delivery_option']) ) {
        $order->update_meta_data( '_chosen_delivery_method', esc_attr($_POST['radio_delivery_option']) );
    }
}

// Display the chosen delivery information
add_filter( 'woocommerce_get_order_item_totals', 'chosen_delivery_item_order_totals', 10, 3 );
function chosen_delivery_item_order_totals( $total_rows, $order, $tax_display ) {;
    $new_total_rows = [];

    // Loop through Order total lines
    foreach($total_rows as $key => $total ){
        // Get the chosen delivery
        $chosen_delivery = $order->get_meta('_chosen_delivery_method');

        if( ! empty($chosen_delivery) && 'payment_method' === $key ){
            $domain = 'woocommerce';
            $label  = __('Delivery method:', 'woocommerce');
            $value  = 'local_pickup' === $chosen_delivery ? __('Local Pickup', $domain) : __('To Your Doorstep', $domain);
            // Display 'Delivery method' line
            $new_total_rows['chosen_delivery'] = array( 'label' => $label,'value' => $value );
        }
        $new_total_rows[$key] = $total;
    }

    return $new_total_rows;
}

代码进入您的活动子主题（或活动主题）的 function.php 文件中。经过测试并且可以工作。
