JsonP with CakePHP

Question

I am working on a CakePHP 2.x app and trying to implement JSONP. It's my first time, so I don't know how can I do this:

$(function(){
 $.getJSON("https://www.example.com/myweb/api/getjsonp&jsoncallback=?",
 function(data){
    console.log(data);
    }
     );

        });

Controller:

public function getjsonp(){

$id = $this->Auth->user('idUser');
$messages = $this->Contact->getMessages($id);


$totalmessages = json_encode($messages);
echo $_GET['jsoncallback'] . '(' . $totalmessages . ')';

}

The code isn't working. Am I missing something?

You are probably not rendering the correct layout/view. See this page on using Json and Xml views.

Steps:

Add Router::parseExtensions('json'); to your router.php file.
Load RequestHandlerComponent in your (App)Controller.
Create a View (named app/View/Api/json/getjsonp.ctp).

Fill View with:

<?php
$totalmessages = json_encode($messages);
echo $_GET['jsoncallback'] . '(' . $totalmessages . ')';

Pass $messages from controller like this:

public function getjsonp() {
  $id = $this->Auth->user('idUser');
  $messages = $this->Contact->getMessages($id);

  $this->set(compact('messages'));
}

Change url from:

https://www.site.com/myweb/api/getjsonp&jsoncallback=?

to

https://www.site.com/myweb/api/getjsonp.json&jsoncallback=?.

Note the .json.
