在 WooCommerce 管理员新订单自定义字段上加载用户自定义数据

Question

受答案代码的启发，我已经能够使用以下代码添加 2 个新的账单和送货字段：

// Checkout and my account (add) unit number and floor number
add_filter( 'woocommerce_billing_fields' , 'custom_field_billing_extra' );
function custom_field_billing_extra( $fields ) {
    $fields['billing_house_number'] = array(
        'type' => 'text', // chose the field type
        //'label' =>  __('Custom label (billing)',  'woocommerce' ),
        'class' => array('form-row-first my-custom-class'), // can be also 'form-row-first' or 'form-row-last'
        'required' => false, // Optional
        'clear' => true, // Optional
        'priority' => 61, // To change the field location increase or decrease this value
        'placeholder' => __('Unit number', 'custom-domain'),
    );
    /////////////////////////////
    
        $fields['billing_floor_number'] = array(
        'type' => 'text', // chose the field type
        //'label' =>  __('Custom label (billing)',  'woocommerce' ),
        'class' => array('form-row-last my-custom-class'), // can be also 'form-row-first' or 'form-row-last'
        'required' => false, // Optional
        'clear' => true, // Optional
        'priority' => 61, // To change the field location increase or decrease this value
        'placeholder' => __('Floor number', 'custom-domain'),
    );
    return $fields;
}


add_filter( 'woocommerce_shipping_fields' , 'custom_field_shipping_extra' );
function custom_field_shipping_extra( $fields ) {
    $fields['shipping_house_number'] = array(
        'type' => 'text', // chose the field type
        //'label' =>  __('Custom label (billing)',  'woocommerce' ),
        'class' => array('form-row-first my-custom-class'), // can be also 'form-row-first' or 'form-row-last'
        'required' => false, // Optional
        'clear' => true, // Optional
        'priority' => 61, // To change the field location increase or decrease this value
        'placeholder' => __('Unit number', 'custom-domain'),
    );
    /////////////////////////////
        $fields['shipping_floor_number'] = array(
        'type' => 'text', // chose the field type
        //'label' =>  __('Custom label (billing)',  'woocommerce' ),
        'class' => array('form-row-last my-custom-class'), // can be also 'form-row-first' or 'form-row-last'
        'required' => false, // Optional
        'clear' => true, // Optional
        'priority' => 61, // To change the field location increase or decrease this value
        'placeholder' => __('Floor number', 'custom-domain'),
    );
    return $fields;
}

// Admin editable single orders shipping and billing new fields
add_filter( 'woocommerce_admin_billing_fields' , 'admin_order_page_new_fields' );
add_filter( 'woocommerce_admin_shipping_fields' , 'admin_order_page_new_fields' );
function admin_order_page_new_fields( $fields ) {
    // Include shipping phone as editable field
    $fields['house_number'] = array( 'label' => __('House Number', 'custom-domain'), 'show' => '0' );
    
    $fields['floor_number'] = array( 'label' => __('floor Number', 'custom-domain'), 'show' => '0' );

    return $fields;
}


// Admin editable User shipping new fields
add_filter( 'woocommerce_customer_meta_fields', 'user_new_field_account' );
function user_new_field_account( $fields ) {
    $fields['billing']['fields']['house_number'][type]  = $fields['shipping']['fields']['house_number'][type]  ='text';
    $fields['billing']['fields']['house_number'][label]  = $fields['shipping']['fields']['house_number'][label]  = __('House Number', 'custom-domain');
    $fields['billing']['fields']['house_number'][description]  = $fields['shipping']['fields']['house_number'][description]  = 'House Number';
    
        $fields['billing']['fields']['floor_number'][type]  = $fields['shipping']['fields']['floor_number'][type]  ='text';
    $fields['billing']['fields']['floor_number'][label]  = $fields['shipping']['fields']['floor_number'][label]  = __('Floor Number', 'custom-domain');
    $fields['billing']['fields']['floor_number'][description]  = $fields['shipping']['fields']['floor_number'][description]  = 'Floor Number';

    return $fields;
}

// add the custom fields to email
add_action('woocommerce_email_customer_details','add_house_number_field_to_emails_notifications', 19, 4 );
function add_house_number_field_to_emails_notifications( $order, $sent_to_admin, $plain_text, $email ) {

    $output = '';
    $shipping_house_number = get_post_meta( $order->id, '_shipping_house_number', true );

    if ( !empty($shipping_house_number) )
        $output .= '<div><strong>' . __('House Number:', 'custom-domain') . '</strong> <span class="text">' . $shipping_house_number . '</span></div>';

    echo $output;
}

add_action('woocommerce_email_customer_details','add_floor_number_checkout_field_to_emails_notifications', 20, 4 );
function add_floor_number_checkout_field_to_emails_notifications( $order, $sent_to_admin, $plain_text, $email ) {

    $output = '';
    $shipping_floor_number = get_post_meta( $order->id, '_shipping_floor_number', true );

    if ( !empty($shipping_floor_number) )
        $output .= '<div><strong>' . __('Floor Number:', 'custom-domain') . '</strong> <span class="text">' . $shipping_floor_number . '</span></div>';

    echo $output;
}

这很好用，但是当我从后端创建手动订单时，值不会从用户数据中提取，它们始终为空。
我错过了什么？

Answer 1

您的代码中有一些错误：现在可以在管理用户页面上正确显示和更改用户数据。

还有一些缺失的代码能够在创建手动新订单时Ajax加载额外的自定义地址字段。

我还在管理员订单可编辑地址和管理员用户仪表板上的正确位置对自定义字段进行了排序（重新排序）。

所以我已经完全重新访问了您的代码。第一个函数处理加载到所有其他函数的自定义字段设置。

代码：

// Custom function that handle the Custom field settings
function custom_checkout_fields_settings() {
    $text_domain = 'custom-domain';

    return array(
        'house_number' => __('House number', $text_domain),
        'floor_number' => __('Floor number', $text_domain),
    );
}

// Add custom billing fields to Checkout and My account edit addresses
add_filter( 'woocommerce_billing_fields' , 'custom_billing_fields' );
function custom_billing_fields( $fields ) {
    $settings = custom_checkout_fields_settings(); // Load settings

    // Loop through setting fields
    foreach ( $settings as $field_key => $field_label ) {
        $fields['billing_'.$field_key] = array(
            'type'        => 'text',
            'placeholder' => $field_label,
            'class'       => $field_key === 'house_number' ? array('form-row-first') : array('form-row-last'),
            'required'    => false,
            'clear'       => true,
            'priority'    => $field_key === 'house_number' ? 61 : 62,
        );
    }
    return $fields;
}

// Add custom shipping fields to Checkout and My account edit addresses
add_filter( 'woocommerce_shipping_fields' , 'custom_shipping_fields' );
function custom_shipping_fields( $fields ) {
    $settings = custom_checkout_fields_settings(); // Load settings

    // Loop through setting fields
    foreach ( $settings as $field_key => $field_label ) {
        $fields['shipping_'.$field_key] = array(
            'type'        => 'text',
            'placeholder' => $field_label,
            'class'       => $field_key === 'house_number' ? array('form-row-first') : array('form-row-last'),
            'required'    => false,
            'clear'       => true,
            'priority'    => $field_key === 'house_number' ? 61 : 62,
        );
    }
    return $fields;
}

// Display editable custom fields on admin single order pages
add_filter( 'woocommerce_admin_billing_fields' , 'admin_single_order_custom_addresses_fields' );
add_filter( 'woocommerce_admin_shipping_fields' , 'admin_single_order_custom_addresses_fields' );
function admin_single_order_custom_addresses_fields( $fields ) {
    $settings = custom_checkout_fields_settings(); // Load settings
    $fields_2 = array(); // Initializing

    // Reorder admin editable fields (Loop through setting fields)
    foreach( $fields as $key => $field_data ) {
        $fields_2[$key] = $field_data;

        // Insert new fields after 'address_2'
        if( 'address_2' === $key )
        {
            // Loop through setting fields
            foreach ( $settings as $field_key => $field_label ) {
                $fields_2[$field_key] = array(

                    'show'          => '0',
                    'wrapper_class' => $field_key === 'floor_number' ? '_billing_phone_field' : '',
                );
            }
        }
    }
    return $fields_2; // return sorted fields
}

// Load Ajax custom field data as customer billing/shipping address fields
add_filter( 'woocommerce_ajax_get_customer_details' , 'add_custom_fields_to_ajax_customer_details', 10, 3 );
function add_custom_fields_to_ajax_customer_details( $data, $customer, $user_id ) {
    $settings = custom_checkout_fields_settings(); // Load settings

    // Loop through setting fields
    foreach( $settings as $field_key => $field_label ) {
        $data['billing'][$field_key] = $customer->get_meta('billing_'.$field_key);
        $data['shipping'][$field_key] = $customer->get_meta('shipping_'.$field_key);
    }

    return $data;
}

// Display reordered editable custom fields on admin single User pages
add_filter( 'woocommerce_customer_meta_fields', 'admin_user_custom_field' );
function admin_user_custom_field( $fields ) {
    $settings = custom_checkout_fields_settings(); // Load settings
    $fields_2 = array(); // Initializing

    // Reorder admin editable fields (loop theough exiting fields)
    foreach( $fields as $fieldset_key => $fieldset_data ) {
        foreach( $fieldset_data as $fieldset_data_key => $data ) {
            if( $fieldset_data_key === 'title' ) {
                $fields_2[$fieldset_key][$fieldset_data_key] = $data;
            } else {
                foreach ( $data as $key => $field ) {
                    $fields_2[$fieldset_key][$fieldset_data_key][$key] = $field;

                    // Insert new fields after "address_2"
                    if( $fieldset_key . '_address_2' === $key )
                    {
                        // Loop through setting fields
                        foreach ( $settings as $field_key => $field_label ) {
                            $fields_2[$fieldset_key][$fieldset_data_key][$fieldset_key.'_'.$field_key] = array(
                                'label'         => $field_label,
                                'description' => '',
                            );
                        }
                    }
                }
            }
        }
    }
    return $fields_2;
}

// Display shipping custom fields values on email notifications
add_action('woocommerce_email_customer_details','display_custom_fields_on_emails_notifications', 30, 4 );
function display_custom_fields_on_emails_notifications( $order, $sent_to_admin, $plain_text, $email ) {
    $settings = custom_checkout_fields_settings(); // Load settings

    // Loop through setting fields
    foreach ( $settings as $field_key => $field_label ) {
        $meta_value = $order->get_meta('_shipping_'.$field_key);
        if ( ! empty($meta_value) ) {
            echo '<div><strong>' . $field_label . ':' . '</strong> <span class="text">' . $meta_value . '</span></div>';
        }
    }
}

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。

现在，当您设置客户时，甚至当您在现有管理订单上加载客户数据（编辑）时，您的自定义字段值会加载到手动管理新订单上。
