CakePhp render a blank view

I have a CakePHP application where all the view works, but two. This is the controller:

 <?php
    App::uses('AppController', 'Controller');
    class CardsController extends AppController {
      public function index() {
      } 
    }
    ?>

And this is the view

<h2>Title</h2>
<?php
echo $this->Form->create('Card', array(
'url' => array(
    'controller' => 'cards',
    'action' => 'view'
)
));
echo $this->Form->input('codice');
echo $this->Form->end('Cerca');*/
?>

Checking with the firefox console I got this:

<html>
  <head></head>
  <body></body>
</html>

The "view" view, called by the form has the same problem. Normally if the view is missing Cake return an error, in this case if I delete the index.ctp the result is in any case a blank page. I can't find what the problem is.

UPDATE 1
My route code:

<?php
Router::connect('/', array('controller' => 'users', 'action' => 'login'));
Router::connect('/pages/*', array('controller' => 'pages', 'action' => 'display'));
CakePlugin::routes();
require CAKE . 'Config' . DS . 'routes.php';
?>

UPDATE 3
Card model

<?php
App::uses('AppModel', 'Model', 'AuthComponent', 'Controller/Component');
class Card extends AppModel {
    public $belongsTo = array('Packet' => array('foreignKey' => 'pacchetto'), 'Tdocumento' => array('foreignKey' => 'iddocument'));
    public $hasMany = array('Visit' => array('foreignKey' => 'codicecarta'));
    public $primaryKey = 'codicecarta';

    public function afterFind($results, $primary = true) {
        for ($i=0; $i < sizeof($results); $i++) { 
            if($results[$i]['Card']['minore'] == 1){
                $results[$i]['Card']['minore'] = 'Yes';
            }else{
                $results[$i]['Card']['minore'] = 'No';
            }
            if($results[$i]['Card']['gratuito'] == 1){
                $results[$i]['Card']['gratuito'] = 'Yes';
            }else{
                $results[$i]['Card']['gratuito'] = 'No';
            }
            $datavalidita = $this->formatodata($results[$i]['Card']['iniziovalidita']);
            $datavisita = $this->formatodata($results[$i]['Card']['dataprenotazione']);
            $results[$i]['Card']['datainizio'] = $datavalidita[0];
            $results[$i]['Card']['orainizio'] = $datavalidita[1];
            $results[$i]['Card']['datavisita'] = $datavisita[0];
            $results[$i]['Card']['oravisita'] = $datavisita[1];
        }
        return $results;
    }

    public $validate = array(
        'nominativo' => array(
            'required' => array(
                'rule' => array('notEmpty'),
                'message' => 'A username is required'
            )
        ),
        'codicecarta'=> array(
            'required' => array(
                'rule' => array('notEmpty'),
                'message' => 'Inserire il codice'
            )
        )
    );
    private function formatodata($dataora){
        $dataora = explode(' ', $dataora);
        $data = $dataora[0]; 
        $data = date('d-m-y', strtotime($data));
        $ora = $dataora[1]; 
        $ora = substr($ora, 0,5);
        return array($data, $ora);
    }
}

The error was sneaky, in the controller, before the php tag there was an empty line. That line broke the flow of the dispatcher of the controller.

Create Cards folder in your View folder and add there index.ctp. You may be missing Folder structure which is convention in cakephp.

Remove */ from your code.

I recommand you to create elements like header.ctp, footer.ctp

And use default.ctp for normal usage like this which will include your header , footer and view content.

<html>

<?php echo $this->element('head'); ?>
<body>


    <?php echo $this->Session->flash(); ?>
    <?php echo $this->fetch('content'); ?>
    <?php echo $this->element('sql_dump'); 
          echo $this->Html->script('additional-methods');           
    ?>

    <div class="footerVersion" style="float: left;
width: 100%;text-align: center;">
        Version : <?php echo VERSION_NUMBER;?>
    </div> 

</body>
</html>

Make sure you have routs.php like this.

<?php    
    //Goto login page if base url is called.
    Router::connect('/', array('controller' => 'Users', 'action' => 'login'));  
/**
 * ...and connect the rest of 'Pages' controller's urls.
 */
    Router::connect('/pages/*', array('controller' => 'pages', 'action' => 'display'));

/**
 * Load all plugin routes. See the CakePlugin documentation on
 * how to customize the loading of plugin routes.
 */
    CakePlugin::routes();

/**
 * Load the CakePHP default routes. Only remove this if you do not want to use
 * the built-in default routes.
 */
    require CAKE . 'Config' . DS . 'routes.php';

An ideal model should look like this :

<?php
App::uses('AppModel', 'Model');
class Card extends AppModel {
}
?>
