What's the way to have a global variable inside a controller?
I have tried to do it using beforeFilter but it is not accessible from the others functions.
Can it only be done using Configure::read
and Configure::write
回答1:
you can set variable accessible in any controller in your AppController
class AppController extends Controller {
public $myGlobalVar;
public function beforeFilter()
{
//this can be anything array, object, string, etc .....
$this->myGlobalVar = "test2";
}
}
then in your other controller you can access variable anywhere like this
class TestController extends AppController {
public function index() {
debug($this->myGlobalVar);
}
}
