Symfony2 How to get the Web or MyBundle directory from inside a controller?

Question

Symfony2. In a controller, I would like to define a path to the Resources/public/pdf directory of a bundle of mine.

If I use __DIR__, I get the path to the Controller directory of my bundle; if $this->get('kernel')->getRootDir(), the path to the App directory. Either way I am not able to move back to the upper directory.

How do I do?

ps. something like $this->get('kernel')->getRootDir().'/../src/ renders .../app/../src/.

EDIT I got what i need by a very simple minded and ugly fix:

$path001 = $this->get('kernel')->getRootDir().'/';
$path002 = explode('/', $path001);
$path003 = array_pop($path002);
$path003bis = array_pop($path002);
$path004 = implode("/", $path002);
$path_pdf  = $path004.'/src/Mario/<MyBundle>/Bundle/Resources/public/pdf';

Is there a better way?

Answer 1

The realpath function (http://php.net/manual/en/function.realpath.php) can clean up all the dot dot stuff if it bothers you.

// From a controller
$resourceDir = realpath(__DIR__ . '/../Resources');

Of course this only works if the controller is in a fixed directory and never moves.

I like to set a parameter using the dependency injection extension.

class CeradProjectExtension extends Extension
{
  public function load(array $configs, ContainerBuilder $container)
  {
    $configuration = new Configuration();
    $config = $this->processConfiguration($configuration, $configs);

    $container->setParameter(
      'sportacus_project_resources_dir',
      realpath(__DIR__ . '/../Resources')
    );

The path can be injected or retrieved from the container.

Answer 2

yes, there is:

$kernel = $this->container->getService('kernel');
$path = $kernel->locateResource('@MarioMyBundle/Resources/public/pdf/file.pdf');
