CakePHP open to new tab on click

I have a function in my app where user can upload files to web server. These uploaded files will then appear in another page where another type of user can click the link. After clicking the link, a new tab will open and the file will be displayed.

But I can't seem to do it. Using 'target' => '_blank' doesn't work, or maybe I put it in the wrong part of the code.

In my case, when you click the link, the file loads on the same tab.

Here is my code:

<?php
    echo $this->Html->link($staff_uploads['StaffUpload']['title'], array(
            'controller' => 'websites', 
            'action' => 'view', 
            'target' => '_blank', 
            $staff_uploads['StaffUpload']['iduploads']
            )
     );
 ?>

Thank you in advance!
