强制在 Woocommerce 订单和电子邮件通知中显示零费用

Question

在 Woocommerce 中，我试图显示自定义费用，当费用金额为零时，使其显示在订单详细信息中table .

基于“Update fee dynamically based on radio buttons in Woocommerce checkout”答案代码，我已设法添加适用于购物车的动态费用并更改客户交付选择。

这是我根据需要改编的工作代码：

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>';
}

现在的问题是，当客户选择 Local Pickup delivery method custom radio button 时，申请的费用等于零 并且根本不显示 在收到订单页面、我的帐户查看订单页面和所有电子邮件通知上。

那么如何像正常费用一样显示（订单总计 table）：

因此显示的总项目行将类似于：

Delivery Fee: N0.00

Answer 1

修改订单详情上方或下方内容有两个钩子table。

woocommerce_email_before_order_table

woocommerce_email_after_order_table

如果您想修改 table 本身 - 将以下文件复制到您的主题 woocommerce/templates/emails/email-order-details.php 。还有一行

            <?php  $deliverfee = get_post_meta($order->get_id(), 'chosen_delivery_option');
            <tr>
                <th class="td" scope="row" colspan="2" style="text-align:<?php echo esc_attr( $text_align ); ?>;"><?php esc_html_e( 'Delivery Fee:', 'woocommerce' ); ?></th>
                <td class="td" style="text-align:<?php echo esc_attr( $text_align ); ?>;"><?php echo  $deliverfee ; ?></td>
            </tr>

Answer 2

零费用案例： 如您所知，当费用为零时，它不会出现在 woocommerce 订单和电子邮件通知中。

但是你可以使用这行简单的代码，让它在任何地方都显示为大于零的费用：

add_filter( 'woocommerce_get_order_item_totals_excl_free_fees', '__return_false' );

代码进入您的活动子主题（或活动主题）的 function.php 文件。已测试并有效。
