2. create a file app_controller.php in /app and write that (or copy
from /cake/app_controller.php):
<?php
class AppController extends Controller {
// callback example
function beforeFilter() {
// will be called for ALL controllers
}
// custom function example
function __myprivate() {
// available in every controller with $this->__myprivate()
}
}
?>
3. look at the content of $this
pr($this)
and you'll see:
$this->name // name of the controller (string)
$this->action // name of the action (string)
$this->params // parameters of the action (array)
$this->passedArgs // named parameters of the action (array)
