在 Woocommerce 编辑订单页面中显示可编辑的自定义字段值

我不是开发人员，但以某种方式设法将 Woocommerce 自定义字段添加到结账和订单编辑页面。有类似的问题，但我找不到正确的解决方案。

自定义字段在管理订单编辑页面中可见但他们不显示值并且不会添加到订单电子邮件中。

我缺少什么？

请看最后的截图。

这是所有代码的组合：

我测试了你的代码，只有一些小错误。您已经非常接近让它按您的预期工作了。所以你应该需要对以下代码进行一些更改：

1）删除了“值”，因为这个挂钩函数适用于结账并且不需要值（当您尝试从不存在的订单中获取它们时更不需要值）。

这将避免隐藏的错误，并在客户已经填写了先前购买中的字段时显示正确的值......

// Add custom Checkout billing fields
add_filter('woocommerce_billing_fields', 'add_woocommerce_billing_fields', 20, 1);
function add_woocommerce_billing_fields( $billing_fields ) {

    $billing_fields['billing_birthday'] = array(
        'type' => 'tel',
        'label' => __('Datum rojstva'),
        'placeholder' => __('dd/mm/yyyy', 'placeholder'),
        'pattern' => __('\d{1,2}/\d{1,2}/\d{4}', 'pattern' ),
        'class' => array('form-row-first'),
        'required' => true,
        'clear' => true
    );

    $billing_fields['billing_socialno'] = array(
        'type' => 'tel',
        'label' => __('Davčna številka'),
        'placeholder' => _x('8-mestna številka', 'placeholder'),
        'class' => array('form-row-last'),
        'required' => false,
        'clear' => true
    );

    return $billing_fields;
}

// Change field type to tel for woocommerce checkout
add_action( 'woocommerce_after_checkout_form', 'change_checkout_field_input_type');
function change_checkout_field_input_type() {
    echo "<script>document.getElementById('billing_postcode').type = 'tel';</script>";
    echo "<script>document.getElementById('billing_birthday').type = 'tel';</script>";
}

2）这里的按键错了，所以这就是字段值不显示的原因在管理订单编辑页面中。

It was 'birthday' and 'socialno'代替'billing_birthday' and 'billing_socialno'.

// Setting custom fields Keys/Labels pairs in admin edit order pages and allow edit this fields correctly.
add_filter('woocommerce_admin_billing_fields', 'add_woocommerce_admin_billing_fields');
function add_woocommerce_admin_billing_fields($billing_fields) {
    $billing_fields['birthday'] = array( 'label' => __('Datum rojstva', 'woocommerce') );
    $billing_fields['socialno'] = array( 'label' => __('Davčna številka', 'woocommerce') );

    return $billing_fields;
}

3）正确获取缺失的字段值显示在订单编辑页面。

// Get the field values to be displayed in admin Order edit pages
add_filter('woocommerce_order_formatted_billing_address', 'add_woocommerce_order_fields', 10, 2);
function add_woocommerce_order_fields($address, $order ) {
    $address['billing_birthday'] = get_post_meta( $order->get_id(), '_billing_birthday', true );
    $address['billing_socialno'] = get_post_meta( $order->get_id(), '_billing_socialno', true );
    return $address;
}

4）其他未更改的挂钩函数：

//Doda user meta v backend profil
add_filter('woocommerce_customer_meta_fields', 'add_woocommerce_customer_meta_fields');
function add_woocommerce_customer_meta_fields($fields) {
    if (isset($fields['billing']['fields'])) {
        $fields['billing']['billing_birthday'] = array(
            'label' => __('Datum rojstva', 'woocommerce'),
            'description' => 'Pa kaj bo končno ratalo memo milo?'
        );
        $fields['billing']['billing_socialno'] = array(
            'label' => __('Davčna številka', 'woocommerce'),
            'description' => ''
        );
    }
    return $fields;
}

add_filter( 'woocommerce_found_customer_details', 'add_woocommerce_found_customer_details', 10, 3);
function add_woocommerce_found_customer_details($customer_data, $user_id, $type_to_load) {
    if ($type_to_load == 'billing') {
        $customer_data[$type_to_load . 'billing_birthday'] = get_user_meta($user_id, $type_to_load . 'billing_birthday', true);
        $customer_data[$type_to_load . 'billing_socialno'] = get_user_meta($user_id, $type_to_load . 'billing_socialno', true);

    }
    return $customer_data;
}

//add_filter('woocommerce_formatted_address_replacements', 'add_woocommerce_formatted_address_replacements', 10, 2);
function add_woocommerce_formatted_address_replacements($replace, $args) {
    $replace['{billing_birthday}'] = !empty($args['billing_birthday']) ? 'Datum rojstva' . $args['billing_birthday'] : '';
    $replace['{billing_socialno}'] = !empty($args['billing_socialno']) ? 'Davčna številka' . $args['billing_socialno'] : '';
    return $replace;
}

add_filter('woocommerce_localisation_address_formats', 'add_woocommerce_localisation_address_formats', 10, 1);
function add_woocommerce_localisation_address_formats($formats) {
    $formats['default'] = $formats['default'] . "\n{billing_birthday}\n{billing_socialno}";
    return $formats;
}

代码位于活动子主题（或活动主题）的 function.php 文件中。

电子邮件通知- 显示自定义字段（及其标签）。

覆盖 Woocommerce 模板emails/email-addresses.php通过您活跃的子主题：

该模板可以通过复制来覆盖：
plugin/woocommerce/templates/emails/email-addresses.php
To yourtheme/woocommerce/emails/email-addresses.php…
官方文档：模板结构和通过主题覆盖模板 https://docs.woocommerce.com/document/template-structure/

您将插入第 34 行之后 （就在计费电话之后）下列：

<?php
    // Billing birthday
    $billing_birthday = get_post_meta($order->get_id(), '_billing_birthday', true );
    echo $billing_birthday ? '<br/>'.__('Datum rojstva', 'woocommerce').': '.$billing_birthday : '';

    // Billing socialno
    $billing_socialno = get_post_meta($order->get_id(), '_billing_socialno', true );
    echo $billing_socialno ? '<br/>'.__('Davčna številka', 'woocommerce').': '.$billing_socialno : '';
?>

经过测试并有效。
