在如何将自定义字段添加到 WooCommerce 注册表单的帮助下，我能够添加自定义注册字段。

• 计费名字
• 计费姓氏
• 计费电话
• 计费 cedula（护照）

通过这两个片段，我可以在结帐页面和我帐户的地址页面中显示自定义字段 CEDULA。

// Hook in
add_filter( 'woocommerce_checkout_fields' , 'custom_override_checkout_fields' );

// Our hooked in function – $fields is passed via the filter!
function custom_override_checkout_fields( $fields ) {
     $fields['billing']['billing_cedula'] = array(
        'label'     => __('Cedula/RUC/Pasaporte', 'woocommerce'),
    'placeholder'   => _x('Numero de identificacion', 'placeholder', 'woocommerce'),
    'required'  => true,
    'class'     => array('form-row-first'),
    'clear'     => true
     );

     return $fields;
}

add_filter('woocommerce_billing_fields', 'custom_woocommerce_billing_fields');

function custom_woocommerce_billing_fields($fields)
{

    $fields['billing_cedula'] = array(
        'label' => __('Cedula/RUC/Pasaporte', 'woocommerce'), // Add custom field label
        'placeholder' => _x('Cedula/RUC/Pasaporte', 'placeholder', 'woocommerce'), // Add custom field placeholder
        'required' => true, // if field is required or not
        'clear' => false, // add clear or not
        'type' => 'text', // add field type
        'class' => array('my-css')    // add class name
    );

    return $fields;
}

但我无法在管理区域显示该字段。有什么帮助吗？
