How to get form values in Symfony2 controller

Question

I am using a login form on Symfony2 with the following controller code

public function loginAction(Request $request)
{
    $user = new SiteUser();
    $form          


        

Answer 1

None of the above worked for me. This works for me:

$username = $form["username"]->getData();
$password = $form["password"]->getData();

I hope it helps.
