CakePHP - How to return string (like JSON) from controller action to Ajax request

Question

So I have my JavaScript making an Ajax call to /my_controller/ajax_action but then in the controller I don\'t know what to do to output something back to the Ja

Answer 1

do this, have your variables you want to output in an array let's say $data, then pass that array to the view using the $this->set('data', $data); method, then create a view /General/SerializeJson.ctp. In that view file, put after that you can use $this->render('/General/SerializeJson'); and it should output the json.

General code...

/Controllers/MyController.php

public class MyController extends AppController
{
    public function ajaxAction()
    {
        $data = Array(
            "name" => "Saad Imran",
            "age" => 19
        );
        $this->set('data', $data);
        $this->render('/General/SerializeJson/');
    }
}

/Views/General/SerializeJson.ctp
