Add data to return of all actions in a Symfony controller

Question

I have a controller in a Symfony 2.1 application, let\'s just call it FooController in the BarBundle. This controller has a lot of actions fooAct

Answer 1

One option is to create your own base controller, and have all other controller extend it. Your base controller would override the render function of the Controller class from symfony framework

use Symfony\Bundle\FrameworkBundle\Controller\Controller;
class BaseController extends Controller
{
    // override render method
    protected function render($template, $data)
    {
        $commonData = [];// get data from wherever you need
        parent::render($template, $data + $commonData);
    }
}

Then in your other controllers

class MyAnotherController extends BaseController
{
    public function fooAction() {
    // ...
    return $this->render('BarBundle:Foo:foo.html.twig', array('foo' => 'Foo Data'));
    }
}

Answer 2

One of options

public function commonAction($type) {
     // ...
     return $this->render('BarBundle:Foo:'.$type.'.html.twig', array('data' => $this->getTheDataThatIsNeededInEveryAction()));
}

where $type would be bar, foo or baz
