Always get AlreadySubmittedException after form is submitted in Symfony -


i'm new symfony need little help.

i have code

    $form->handlerequest($request);      if ($request->ismethod('post')) {         $form->submit($request);         if ($form->isvalid()) {             //todo         }          return $this->redirect($this->generateurl('news'));     }

when form submitted, obtain 500 internal server error - alreadysubmittedexception.

you should use $form->handlerequest or $form->submit, not both.
