CakePHP Work Note 20110601_ controller access to the remaining controller methods

CakePHP Work Note access other controller methods in 20110601_ controller
Requestaction (string $url, array $options)

This function calls a controller's action from any location and returns data from the action. The $url passed is a cakephp-relative url (/controllername/actionname/params). To pass extra data to the receiving controller action add to the $options array.
You can use Requestaction () to retrieve a fully rendered view by passing ' return ' in the Options:requestaction ($url, Arra Y (' return ')); It is important to note this making a requestaction using ' return ' from a controller method can cause script and CSS tags to does work correctly.

If used without caching requestaction can leads to poor performance. It is the rarely appropriate to use in a controller or model.

Requestaction is the best used in conjunction with (cached) Elements–as A-to-fetch data for an element before rendering. Let's use the example of putting a "latest comments" element in the layout. First we need to create a controller function, that would return the data.
When a action is called through Requestaction $this->params[' requested ') is the set to 1 as an indicator. So checking this can either return the required data else set it a view variable like you normally would. This helps keep things DRY.
Example:
The method of calling Stores_houses in the Air_status controller Shlistdir
function Airscene ()
{
$this->layout = "iframe";
$rs = $this->requestaction ('/stores_houses/shlistdir ');
$this->set (' Test ', $rs);
}
