订单自定义字段不显示在WooCommerce的电子邮件通知中。

问题描述 投票：1回答：2

我写了一个小插件，可以在结账页面添加几个自定义字段。这些字段与B2B买家有关，所以他们可以输入公司名称、许可证号和地址。

一切都很正常，除了这些值没有显示在订单邮件中，最重要的是，订单完成邮件。

以下是我遇到问题的部分代码

add_filter('woocommerce_email_order_meta_fields', 'mx_woocommerce_email_order_meta_fields');

function mx_woocommerce_email_order_meta_fields( $fields ) {

    if (isset($_POST['r1_checkbox']) && !empty($_POST['r1_checkbox'])) {
        echo '<h2>R1 račun za kupca</h2>';

        $fields[] = 'Ime tvrtke';
        $fields[] = 'Adresa tvrtke';
        $fields[] = 'OIB tvrtke';

        return $fields;
    }
}

想不通是哪里出了问题。我也试过用 $keys 而不是 $fields 但这并没有帮助。

更新 (全码):

function mx_custom_checkout_field( $checkout ) {

你的代码这里和那里有一些小错误，我已经修改了。

我还改了一个废弃的钩子。

  • woocommerce_email_order_meta_keys 通过 woocommerce_checkout_create_order

取而代之的是一个大大挪用的钩子。

  • woocommerce_checkout_update_order_meta 由 woocommerce_email_order_meta_fields

你的函数代码中存在一些错误。为了使它工作，使用以下方法。

add_filter( 'woocommerce_email_order_meta_fields', 'filter_email_order_meta_fields_callback', 10, 3 );
function filter_email_order_meta_fields_callback( $fields, $send_to_admin, $order ) {
    if ( $order->get_meta('R1 račun') ) {
        echo '<h2>R1 račun za kupca</h2>';

        // Defined array of meta keys (labels)
        $meta_keys = ['Ime tvrtke', 'Adresa tvrtke', 'OIB tvrtke'];

        // Loop though meta keys array to set the fields
        foreach( $meta_keys as $meta_key ){
            if( $meta_value = $order->get_meta($meta_key) ){
                $fields[] = array(
                    'label' => $meta_key,
                    'value' => $meta_value,
                );
            }
        }
    }
    return $fields;
}

代码在你的活动的子主题（或活动主题）的function.php文件中。经过测试，工作。

注意：你需要删除下面的内容，因为它是在你的活动主题（或活动主题）的function.php文件中。 你需要删除以下内容，因为它是... 弃用 和 不用 不再。

add_filter('woocommerce_email_order_meta_keys', 'mx_woocommerce_email_order_meta_keys');

    if ( $_POST['r1_checkbox'] ) {
        echo '<h2>R1 račun za kupca</h2>';

        $keys[] = 'Ime tvrtke';
        $keys[] = 'Adresa tvrtke';
