How can I get the action name in a Symfony2 controller? - php

Question

Is there a way to get the name of the action in a Symfony2 controller?
public function createAction(Request $request, $title) {
// Expected result: create
$name = $this->getActionName();
}

Answer 1

use：
$request->attributes->get('_controller');
// will get yourBundle\Controller\yourController::CreateAction
$params = explode('::',$request->attributes->get('_controller'));
// $params[1] = 'createAction';
$actionName = substr($params[1],0,-6);
// $actionName = 'create';

I found this snippet (here):
$matches = array();
$controller = $this->getRequest()->attributes->get('_controller');
preg_match('/(.*)\\\(.*)Bundle\\\Controller\\\(.*)Controller::(.*)Action/', $controller, $matches);
which seems to be a promising approach. This regexp actually doesn't work. But it won't be hard to fetch the action name by using strstr(). Works!
And returns (see example)
Array
(
[0] => Acme\MyBundle\Controller\MyController::myAction
[1] => Acme
[2] => My
[3] => My
[4] => my
)
If input was Acme\MyBundle\Controller\MyController::myAction.

Now, I am using this with Symfony 2.8, (and Symfony3):
<?php
namespace Company\Bundle\AppBundle\Component\HttpFoundation;
use Symfony\Component\HttpFoundation\Request as BaseRequest;
/**
* Request shortcuts.
*/
class Request extends BaseRequest
{
/**
* Extract the action name.
*
* #return string
*/
public function getActionName()
{
$action = $this->get('_controller');
$action = explode('::', $action);
// use this line if you want to remove the trailing "Action" string
//return isset($action[1]) ? preg_replace('/Action$/', '', $action[1]) : false;
return $action[1];
}
/**
* Extract the controller name (only for the master request).
*
* #return string
*/
public function getControllerName()
{
$controller = $this->get('_controller');
$controller = explode('::', $controller);
$controller = explode('\\', $controller[0]);
// use this line if you want to remove the trailing "Controller" string
//return isset($controller[4]) ? preg_replace('/Controller$/', '', $controller[4]) : false;
return isset($controller[4]) ? $controller[4] : false;
}
}
To use this custom request class, you must "use" it in your web/app*.php controllers:
use Company\Bundle\AppBundle\Component\HttpFoundation\Request;
// ...
$request = Request::createFromGlobals();
// ...
Then in your controller:
class AppController extends Controller
{
/**
* #Route("/", name="home_page")
* #Template("")
*
* #return array
*/
public function homePageAction(Request $request)
{
$controllerName = $request->getControllerName();
$actionName = $request->getActionName();
dump($controllerName, $actionName); die();
// ...
}
Will output:
AppController.php on line 27:
"AppController"
AppController.php on line 27:
"homePageAction"
You can also access these functions through the RequestStack service:
class MyService
{
/**
* #param RequestStack $requestStack
*/
public function __construct(RequestStack $requestStack)
{
$this->requestStack = $requestStack;
}
public function myService()
{
$this->controllerName = $this->requestStack->getMasterRequest()->getControllerName();
$this->actionName = $this->requestStack->getMasterRequest()->getActionName();
// ...
}

If you use Controller as a Service than the schema is different:
$request->attributes->get('_controller'); will return "service_id:createAction"
A possible solution for both schemas:
$controller = $request->attributes->get('_controller');
$controller = str_replace('::', ':', $controller);
list($controller, $action) = explode(':', $controller);

In all version of symfony and without $request or container, service or nothing else... , directly in your method
public function myMethod(){
$methodName = __METHOD__;
return $methodName;
}
// return App\Controller\DefaultController::myMethod
public function mySecondMethod(){
$methodName = explode('::', __METHOD__);
return $methodName[1];
}
// return mySecondMethod
