When developing VisitorChat, a CakePHP-based live-chat application, I needed to add a plain and simple JSONP-renderer.
At the time, CakePHP did not yet have the JSONP serialiser included, so I went ahead and added JSONP support with a few simple lines of code.
If you are using an older version of CakePHP this may be useful to you. So here we go – just add it to your AppController:
1
2
3
4
5
6
7
8
9
10
11
| /**
* Handles the rendering all jsonp responses
* @param array $data Array of data to be rendered
*/
public function __renderJsonp($data = array())
{
$this->autoRender = false;
$this->response->type('js');
$return = sprintf('%s(%s)', h($this->request->query('callback')), json_encode($data));
$this->response->body($return);
} |
/**
* Handles the rendering all jsonp responses
* @param array $data Array of data to be rendered
*/
public function __renderJsonp($data = array())
{
$this->autoRender = false;
$this->response->type('js');
$return = sprintf('%s(%s)', h($this->request->query('callback')), json_encode($data));
$this->response->body($return);
}
That’s all! Now, you can simply call $this->__renderJsonp(array(‘your’ => ‘data’)); to return your JSONP from within any CakePHP controller action.
