I suggest that you use the event system to accomplish this, as it does
exactly what you're describing:

http://book.cakephp.org/2.0/en/core-libraries/events.html

So, let's say you have a Navigation plugin and you want to gather
navigation items from every plugin in your app. When you want to
gather the items, you'd broadcast an event. You'd have listeners in
each plugin that would listen for the broadcast and return the items
you want.

Sure, I know I'm able to use Interfaces where I want to. I just want to

know if there is a easier way to do this using the CakePHP Plugins. And if

isn't, if there is a pattern to use Interfaces and let the CakePHP

autoinclude them, like it did with the MVC classes.

Thanks,

CakePHP is just PHP, so there's no reason you couldn't use interfaces

where you wanted to. The users of the plugins would just need to understand

that they need to implement them.

Hello all,

Did everyone tried to use PHP's Interface as Extension Point in CakePHP?

My idea is to create a fully modular app. To build a menu, for example, I

would be able to do something like this:

The method 'getExtensionPoint' will get all the classes that implements

the given interface, at run time.

// The core of extension point

class MenuController {

  function _buildMenu() {

    $menu = array();

    $menuProviders = $this->getExtensionPoint('IMenu');

    foreach($menuProviders as $menuProvider) {

      $menu += $menuProvider->getMenu();

    }

  }

}

// Some class ( could be a Controller or a Model ) which uses this

extension point

class User implements IMenu {

  function getMenu() {

    return array('Users' => '/user/list');

  }

}

// The Interface, to bind the extended classes

public interface IMenu {

  function getMenu();

}

Sorry for write all this code here.

Someone already did something like this? This can be done using the

plugins in CakePHP ?

Thanks in advance !
