Access to module config in Zend Framework 2

Question

How I can get access to my module config from the controller?

Answer 1

What exactly do you want to do in your controller with the module configuration? Is it something that can't be done by having the DI container inject a fully configured object into your controller instead?

For example, Rob Allen's Getting Started with Zend Framework 2 gives this example of injecting a configured Zend\Db\Table instance into a controller:

return array(
'di' => array(
    'instance' => array(
        'alias' => array(
            'album' => 'Album\Controller\AlbumController',
        ),
        'Album\Controller\AlbumController' => array(
            'parameters' => array(
                'albumTable' => 'Album\Model\AlbumTable',
            ),
        ),
        'Album\Model\AlbumTable' => array(
            'parameters' => array(
                'config' => 'Zend\Db\Adapter\Mysqli',
        )),
        'Zend\Db\Adapter\Mysqli' => array(
            'parameters' => array(
                'config' => array(
                    'host' => 'localhost',
                    'username' => 'rob',
                    'password' => '123456',
                    'dbname' => 'zf2tutorial',
                ),
            ),
        ),
        ...

If you need to do additional initialization after the application has been fully bootstrapped, you could attach an init method to the bootstrap event, in your Module class. A blog post by Matthew Weier O'Phinney gives this example:

use Zend\EventManager\StaticEventManager,
Zend\Module\Manager as ModuleManager

class Module
{
    public function init(ModuleManager $manager)
    {
        $events = StaticEventManager::getInstance();
        $events->attach('bootstrap', 'bootstrap', array($this, 'doMoarInit'));
    }

    public function doMoarInit($e)
    {
        $application = $e->getParam('application');
        $modules     = $e->getParam('modules');

        $locator = $application->getLocator();
        $router  = $application->getRouter();
        $config  = $modules->getMergedConfig();

        // do something with the above!
    }
}

Would either of these approaches do the trick?
