How do I Get the Current Route in Symfony 2?

Determining the Current Route in Symfony 2

In Symfony 2, obtaining the active route is a common task, particularly when developing web applications. This route information provides context for understanding the application's current state.

Fetching the Route Name

To retrieve the current route, follow these steps:

1. Ensure that your controller or service is implementing the ContainerAware interface.
2. Obtain the Request object from the container:

<code class="php">$request = $this->container->get('request');</code>

3. Extract the route name using the _route parameter from the request:

<code class="php">$routeName = $request->get('_route');</code>

This will return the name of the currently active route, such as "somePage" in the example provided.

Example:

Consider the following routing configuration in routing.yml:

<code class="yaml">somePage:
    pattern: /page/
    defaults: { _controller: "AcmeBundle:Test:index" }</code>

To retrieve the "somePage" route name in a controller, you would use the following code:

<code class="php">use Symfony\Component\HttpFoundation\Request;

class TestController extends Controller
{
    public function indexAction(Request $request)
    {
        // Get the current route name
        $routeName = $request->get('_route');
    }
}</code>

This allows you to access the current route's name within your application logic, enabling more flexible and context-aware development.
