What I prefer (for a component but I think its the same for a helper).


class AppController extends Controller {
	var $components = array('Session', 'MySession');
	function constructClasses() {
		parent::constructClasses();
		$this->Session = $this->MySession;
	}
class MySessionComponent extends SessionComponent {
	function setFlash($message, $layout = 'default', $params = array(), $key = 'flash') {
		// my override;
	}
}
?>

@cakebaker – re migration – cheers all went smoothly and we don’t switch off the old server till the end of the month anyway. It’s just the sheer bloody tedium of it… It is really boring and you have to concentrate really hard too… luckily most of the domains emails are managed elsewhere which makes it a lot easier…

But anyway, finally got the chance to do a bit of speculative baking and try this out – very easy and very straight forward. I’m going to play around with all the various solutions people have suggested.

Anyway one of these will be a good fit with my original idea. ( which was to see if there was a way of testing the permissions on internal links (i.e. in the admin side of site) so you only see the links to actions / views you are actually allowed to… easy to do with a custom helper but modifying $html->link means you could retro fit it to any site with very little fuss.)

@ADmad: Thanks for your comment and for sharing your approach! It is a bit more cleaner than what I described in the article.

How about this


// app/app_controller.php
class AppController extends Controller {
    public $view = 'Example';
    public $helpers = array('Example');
}


// app/views/example.php
class ExampleView extends View {
    public function &_loadHelpers(&$loaded, $helpers, $parent = null) {
        $loaded = parent::_loadHelpers($loaded, $helpers, $parent);

		if(isset($loaded['Example'])) {
			$loaded['Html'] = $loaded['Example'];
			unset($loaded['Example']);
		}
		
        return $loaded;
    }
}

I would prefer specifying my helper in the $helpers array instead of all that extra code in overridden _loadHelpers function.

@John: Good luck with your migration!

@grigri: I don’t know what happened with this feature, it probably got forgotten :|

This has actually been discussed on the google groups, with no definitive solution.

(there are others too)

Nate said that he had implemented it (the alias thing), but not yet put in in the core because it wasn’t test-covered. This was in February ‘08. I wonder what happened?

@grigri – I really like your idea from the previous post – to create base helpers that can then be extended would be a nice way to go – it feels like quite an elegant solution if you know what I mean – and I would think be relatively straight forward to implement – plus it wouldn’t need break backward compatability.

Matt’s suggestion (array(’Html’ => ‘MyHtmlHelper’)) is very similar in a way (although the other way around) , I suppose MyHtmlHelper could either extend or just override – giving the developer the responsibility / flexibility

@cakebaker – Unfortunately I haven’t had a chance to try this out yet, I’ve got an exciting week of server migration ahead of me…

It’s a shame none of the core devs have commented on this – I (and I doubt I’m alone) would like to hear if this issue is ever to be resolved within the core; if the idea of renaming core helpers is anathema to cake’s design principles; what methods the core devs use to customize helpers themselves, etc…

Maybe the post wasn’t inflammatory enough? :)
