Question

I don’t get why the variables are not changed in the AppController. I have a subclass of AppController and in the action method, I am changing a variable of AppController. However this does not get reflected in the afterFilter.

This is CakePHP’s AppController

<?php

class AppController extends Controller {

    var $xxxx;

    function beforeFilter()
    {
        $this->xxxx = 'this should be changed';
    }

    function afterFilter()
    {
        var_dump($this->xxxx);
        exit;
    }


}
?>

And this is my UsersController

<?php

class UsersController extends AppController {


    function view( $id )
    {
        echo "From the AppController: {$this->xxxx} \n";
        $this->xxxx = 'with this';
    }

}
?>

This is the output when I run it:

From the AppController: this should be changed
string 'this should be changed' (length=22)

I am expecting this:

From the AppController: this should be changed
string 'with this' (length=9)

Do you know why it behaves this way? Any pointers how to do this correctly?

Answer 1

You should use beforeRender() instead of afterFilter().

Request Life-cycle callbacks will surely help you to achieve the same.

Kindly ask if it not worked for you.
