我是Symfony2的noobie.该handleRequest()函数不适用于"GET"方法,而相同的代码适用于"POST".

public function addAction(Request $request){
    $std = new Student();

    $form = $this->createForm(new StudentForm, $std, 
        array( 'method'=>'GET'));

    $form->handleRequest($request);

    if($form->isSubmitted()){
        $std= $form->getData();
        $em= $this->getDoctrine()->getManager();
        $em->persist($std);
        $em->flush();
        return $this->render('target.twig');
    }

    return $this->render('target twig', 
        array('newStdForm'=> $form->createView(),));
}

上面的代码不起作用,但如果我'method':'GET'改为'method':'POST',那么它工作正常.

如何在控制器中捕获异常并在Symfony 2中显示flash消息？

try{
  $em = $this->getDoctrine()->getManager();
  $em->persist($entity);
  $em->flush();

  return $this->redirect($this->generateUrl('target page'));
} catch(\Exception $e){
  // What to do in this part???
}

return $this->render('MyTestBundle:Article:new.html.twig', array(
  'entity' => $entity,
  'form'   => $form->createView(),
));

该怎么办catch？

你好，我是 php、html、css 和 smarty 的新手。如何在smarty中将css文件插入/包含到html文件中？
