Hello

Is there a simple way of doing the following :

Creating a menu item from the site tree that would download a file from the assests folders
Would trying to change the redirector page behaviour a good idea ?

Thank you

I'd use a redirector page and then add this code within it...

or you could just take the URL from the asset itself and specify the entire url (I think it's say link to another site) but it should work.

ok, create a new page type "file download page" in db add has_one file to it, update cmsfields to pick the file
also add the controller function as described in the link (http://www.silverstripe.org/general-questions/show/15832)
that page can then be placed directly into the sitetree

maybe this will help then...

<?php

class FilePage extends Page {

   static $has_one = array(
      'MyFile' => 'File'
   );

   function getCMSFields(){
      $fields = parent::getCMSFields();

      $fields->addFieldsToTab('Root.Content', array(
         new FileIFrameField('MyFile', 'My File')
      ));

      return $fields;
   }
}

class FilePage_Controller extends Page_Controller {
   //do send_file stuff here
}

Hello Swaiba

I could not try your code before but I did today and I get an error
so here is my code now (I have added the file download part)

<?php

class FilePage extends Page {

static $has_one = array(
'MyFile' => 'File'
);

function getCMSFields(){
$fields = parent::getCMSFields();

$fields->addFieldsToTab('Root.Content', array(
new FileIFrameField('MyFile', 'My File')
));

return $fields;
}
}

class FilePage_Controller extends Page_Controller {
public function download(){

$assetID = $this->request->param('ID');

$do = DataObject::get_by_id('File', $assetID);

if($do && file_exists($do->URL)){
return SS_HTTPRequest::send_file(file_get_contents($do->URL), $do->Name);
}else{
echo 'error with ' . $do->URL . ' (' . file_exists($do->URL) . ')';
return false;
}

}
}

and this is the error I get

ERROR [User Error]: Uncaught Exception: Object->__call(): the method 'settabset' does not exist on 'FileIFrameField'

try ImageField instead of FileIFrameField

that code wasn't tested - there should be something in the basic tutorial about adding a picture (of an author to an article page)
