How to add an auxiliary or on-the-fly component using the controller action method

Question

I do not want to add it as below, because I needed them only once in a certain method of action

(so it's not useless to load memory)

class UsersController extends AppController {
    var $name = 'Users';
    var $helpers = array('Html', 'Session');
    var $components = array('Session', 'Email');

Answer 1

class UsersController extends AppController {
  public function method_name() {
    $this->helpers[] = 'MyHelper'
  }
}

Read more about this in the documentation .

Hope this helps.

Answer 2

You can download helpers using

$this->helpers[] = 'MyHelper';

as mentioned above in Rob, but this will not work for controllers, because they have their own initialization and startup methods that must be called for their operation.

:

$this->Common->addHelper('Tools.Datetime');
$this->Common->addHelper(array('Text', 'Number', ...));
$this->Common->addComponent('RequestHandler');
$this->Common->addLib(array('MarkupLib'=>array('type'=>'php'), ...));
