你好，我发现了一个自定义的形式WordPress的，我想通过一些输入（街道，邮政编码，ustid，国家，电话号码）扩展。默认情况下，wp_insert_user（）只能有特定的键（如user_login、user_pass.）。因此，需要使用update_user_Meta（）来更新像地址和USt-iD这样的账单/shippindadress输入（如果有更简单的方法，我希望得到答案）：

function red_registration_form($atts) {
     $atts = shortcode_atts( array(
        'role' => 'subscriber',         
    ), $atts, 'register' );
    
$role_number = $atts["role"];
 if ($role_number == "shop_manager" ) { $reg_form_role = (int) filter_var(AUTH_KEY, FILTER_SANITIZE_NUMBER_INT); }  elseif ($role_number == "customer" ) { $reg_form_role = (int) filter_var(SECURE_AUTH_KEY, FILTER_SANITIZE_NUMBER_INT); } elseif ($role_number == "contributor" ) { $reg_form_role = (int) filter_var(NONCE_KEY, FILTER_SANITIZE_NUMBER_INT); } elseif ($role_number == "author" ) { $reg_form_role = (int) filter_var(AUTH_SALT, FILTER_SANITIZE_NUMBER_INT); } elseif ($role_number == "editor" ) { $reg_form_role = (int) filter_var(SECURE_AUTH_SALT, FILTER_SANITIZE_NUMBER_INT); }   elseif ($role_number == "administrator" ) { $reg_form_role = (int) filter_var(LOGGED_IN_SALT, FILTER_SANITIZE_NUMBER_INT); } else { $reg_form_role = 1001; } 
    
    if(!is_user_logged_in()) { 
        $registration_enabled = get_option('users_can_register');
        if($registration_enabled) {
            $output = red_registration_fields($reg_form_role);
        } else {
            $output = __('<p>User registration is not enabled</p>');
        }
        return $output;
    }  $output = __('<p>You already have an account on this site, so there is no need to register again.</p>');
    return $output;

我的目标是，每次创建一个用户时，账单/送货地址也会更新。wp_isert_user（）可以正常工作，但是一旦创建了用户，带有update_user_Meta（）的发货/账单地址字段就不会出现在用户信息中。我做错了什么？谢谢你的帮助提前。
