Zend Framework 2: Getting current controller name inside a module - php

Question

I'm creating a module X that will be instantiated inside a controller module. How can I get the name of that controller in a method of module X?
This module is not a controller, nor a view or layout.
An example. This is an action in the controller:
public function indexAction {
$parser = new Parser();
}
And this my new module Parser, where I need to know the controller's name.
public function __construct() {
$controller_name = ???
}

Answer 1

For such dependencies you should use a factory to create your service instance. Then you can inject whatever you want in there, also a controller name. Your ParserFactory could for example look like this:
<?php
namespace Application\Factory;
use Zend\ServiceManager\FactoryInterface;
use Zend\ServiceManager\ServiceLocatorInterface;
use Application\Service\Parser
class ParserFactory implements FactoryInterface
{
/**
* #param ServiceLocatorInterface $serviceLocator
* #return Parser
*/
public function createService(ServiceLocatorInterface $serviceLocator)
{
$routeMatch = $serviceLocator->get('Application')->getMvcEvent()->getRouteMatch();
$controllerName = $routeMatch->getParam('controller');
$parser = new Parser($controllerName);
return $parser;
}
}
Your Parser class:
<?php
namespace Application\Service;
class Parser
{
/**
* #param string $controllerName
*/
public function __construct($controllerName)
{
//... use your controller name ...
}
}
Register your factory in module.config.php like this:
'service_manager' => array(
'factories' => array(
'Parser' => 'Application\Factory\ParserFactory',
)
)
Get your service where you need it from the ServiceManager like this:
$parser = $serviceManager->get('Parser');

I think this has been asked before but I think you do:
$this->getEvent()->getRouteMatch()->getParam('controller', 'index');
You should just be able to grab it all from the router.
