Access Route Parameters in twig Template

How can I access route parameters in a twig template without knowing the name of the parameter/s ?

You can get all route parameters with:

{{ app.request.attributes.get('_route_params') }}

if you want just one parameter:

{{ app.request.attributes.get('_route_params')['YOUR_PARAMETER_KEY'] }}

if you want to use the current route with its parameter as a url:
>{{ path(app.request.get('_route'),app.request.get('_route_params')) }}

This can be helpful when you want to eliminate any concatenated strings from the url.

app.request.get('_route') gives you the route name from request bag.
app.request.get('_route_params') gives you the route parameters
{{ path(route_name, array of parameters) }} create the path

Route parameters can be accessed in the following way in Twig:

{{ app.request.attributes }}

You can also use the [`dump()`](

) function to see what methods are available:

<pre>
{{ dump(app.request.attributes) }}
</pre>

Here's a dump of all the parameters:

Route = test
Slug = {param1} = 3

**Twig Code**

{{ dump(app.request.attributes) }}

**Returns**

object(Symfony\Component\HttpFoundation\ParameterBag)[10]
protected 'parameters' =>
array (size=3)
'_controller' => string 'MyTest\Bundle\Controller\TestController::indexAction' (length=61)
'param1' => string '3' (length=1)
'_route' => string 'test' (length=7)
