如以下代码所示，在config / routes.php文件中进行更改。

config / routes.php

setRouteClass(DashedRoute::class);
$routes->scope('/', function (RouteBuilder $builder) {
   $builder->registerMiddleware('csrf', new CsrfProtectionMiddleware([
      'httpOnly' => true,
   ]));
   $builder->applyMiddleware('csrf');

在以下位置创建RegistrationsController.php文件

src / Controller / RegistrationsController.php。将以下代码复制到控制器文件中。

src / Controller / RegistrationsController.php

set('country',$country);
         $gender = array('Male','Female');
         $this->set('gender',$gender);
      }
   }
?>

在src / Template上创建目录Registrations ，然后在该目录下创建一个名为index.php的View文件。将以下代码复制到该文件中。

src / Template / Registrations / index.php

Form->create(NULL,array('url'=>'/register'));
   echo 'Country';
   echo $this->Form->select('country',$country);
   echo 'Gender';
   echo $this->Form->radio('gender ',$gender);
   echo 'Address';
   echo $this->Form->textarea('address');
   echo $this->Form->file('profilepic');
   echo ''.$this->Form->checkbox('terms').
      'Terms ∓ Conditions';
   echo $this->Form->button('Submit');

?>
