Wordpress 将签出字段添加到右列，而不是左列

我正在将woocommerce与自定义主题集成。添加自定义签出字段时，它会显示在左列所有其他字段的底部。我希望它出现在右边一栏的文本区域“订单注释”下面

functions.php中的代码：

// Change Checkout Fields
add_filter( 'woocommerce_checkout_fields' , 'custom_override_checkout_fields' );
function custom_override_checkout_fields( $fields ) {
    // Add new fields to checkout
     $fields['billing']['card_requests'] = array(
        'type'      => 'textarea',
        'label'     => __('Card Requests', 'woocommerce'),
        'placeholder'   => _x('Please enter messages for your handwritten cards here.', 'placeholder', 'woocommerce'),
        'required'  => false
     );
    return $fields;
}

// Change Checkout Fields
add_filter( 'woocommerce_checkout_fields' , 'custom_override_checkout_fields' );
function custom_override_checkout_fields( $fields ) {
  // Add new fields below order notes section
  $fields['order']['card_requests'] = array(
    'type'      => 'textarea',
    'label'     => __('Card Requests', 'woocommerce'),
    'placeholder'   => _x('Please enter messages for your handwritten cards here.', 'placeholder', 'woocommerce'),
    'required'  => false
  );
  return $fields;
}

在输出的HTML中，有一个col-1 div和一个col-2 div。我认为这是来自

templates/formcheckout.php

：

        <div class="col-1">
            <?php do_action( 'woocommerce_checkout_billing' ); ?>
        </div>
        <div class="col-2">
            <?php do_action( 'woocommerce_checkout_shipping' ); ?>
        </div>

在functions.php中添加以下内容：

// Change Checkout Fields
add_filter( 'woocommerce_checkout_fields' , 'custom_override_checkout_fields' );
function custom_override_checkout_fields( $fields ) {
    // Add new fields to checkout
     $fields['billing']['card_requests'] = array(
        'type'      => 'textarea',
        'label'     => __('Card Requests', 'woocommerce'),
        'placeholder'   => _x('Please enter messages for your handwritten cards here.', 'placeholder', 'woocommerce'),
        'required'  => false
     );
    return $fields;
}

// Change Checkout Fields
add_filter( 'woocommerce_checkout_fields' , 'custom_override_checkout_fields' );
function custom_override_checkout_fields( $fields ) {
  // Add new fields below order notes section
  $fields['order']['card_requests'] = array(
    'type'      => 'textarea',
    'label'     => __('Card Requests', 'woocommerce'),
    'placeholder'   => _x('Please enter messages for your handwritten cards here.', 'placeholder', 'woocommerce'),
    'required'  => false
  );
  return $fields;
}

杰出的非常感谢。（更改为$fields['billing']到$fields['order']）
