Try var $helper = array('CssMenu') as cakephp conventions

Re: adding helper

 in AppController I've got two default helpers:

 var $helpers = array('html','javascript');

 in EmployeesController I want to use another helper, the Child helper.
 It is possible by typing:

 var $helpers = array('Html', 'Javascript', 'Child');

 Question is:
 when I add 'scriptaculous' helper into AppController, do I have to
 update all my controllers and add 'scriptaculous' to all helpers or
 there is some way to just extend default helper array?
 
 Thanks in advance,
 a.

Re: adding helper

[Andrej]

As I've got solution I post it to community.
According to http://www.php.net/manual/en/keyword.parent.php it's
impossible to access parent variables using parent::
The only way to access parent variable is _not_ to use same variable
name in derived class.

So I put a new variable into my custom Controller and wrote constructor
to merge helper definition arrays.

app_controller.php:
?php
class AppController extends Controller {
var $helpers = array('html','javascript');
}
?

controllers/investors_controller.php:
?php
class InvestorsController extends AppController {
var $extendHelpers = array('Child', 'Contact');
function __construct(){
parent::__construct();
$this-helpers = array_merge($this-helpers, 
$this-extendHelpers);
}
}
?

Re: adding helper

[meek]

Hi,
Your solution shouldn't be necessary.
Cake merges $helper, $component and even $uses arrays automatically.
So if you have ...
var $helpers = array('Html','Javascript');
... in your AppController, and ...
var $helpers = array('MyHelper');
... in your child controller, then all three Helpers will be available
in your child controller's views. You should watch out with case
though, the names of the helpers in these arrays should always be
capitalized.

Meek,
you are right.
At least I get familiar with inheritance model in cakephp.
Thanks,
