我正在努力完成一项杀死我的任务！ 我只能在没有成功的情况下收到一条丑陋的信息！ 请看下面我的两个简单的类......他们假装通过我的应用程序中的表单发送电子邮件，根据通过提到的表格（产品和城市）插入的两个标准选择我的数据库中的人员。
出现此错误的可能原因是什么：
An exception occurred while executing 'SELECT u0_.email AS email0 FROM userInfo u0_ WHERE u0_.city = ? AND u0_.products = ? LIMIT 1' with params [{}, {}]:
Catchable Fatal Error: Object of class Quotera\EmailBundle\Entity\Email could not be converted to string
public function EmailAction(Request $request){
$email = new Email();
$form = $this->createForm(new EmailType());
if ($request->isMethod('POST')) {
$form->submit($request);
if ($form->isValid()) {
$city = $email->setCity($form->get('city')->getData());
$product =$email->setProduct($form->get('product')->getData());
$user = $this->getUser();
$email->setOwner($user);
$email->setName($user);
$email->setCity($form->get('city')->getData());
$email->setProduct($form->get('product')->getData());
$email->setMessage($form->get('message')->getData());
$email->setEmail("exellent@sometoon.com");
$email->setEmailTo($this->sendEmailsToProviders($city, $product));
$email->setTime($form->get('time')->getData());
$em = $this->getDoctrine()->getManager();
$em->persist($email);
$em->flush();
$message = \Swift_Message::newInstance()

->setTo($this->sendEmailsToProviders($city,$product))
->setCharset('utf-8')
->setContentType('text/html')
->setBody('Thank you', 'text/html');
$this->get('mailer')->send($message);
$request->getSession()->getFlashBag()->add('success', 'Your quotation has been sent' );
}
}
return array(
'form' => $form->createView()
);
}
public function sendEmailsToProviders($city, $product)
{
$em = $this->getDoctrine ()->getManager();
$qb = $em->createQueryBuilder();
$emails = $qb->select('u')->from('UserBundle:userInfo', 'u')
->select('u.email')
->andWhere('u.city = :city')
->setParameter('city', $city)
->andWhere('u.product = :product')
->setParameter('product', $product )
->setMaxResults(5)
->getQuery()
->execute();
if(!$emails){
throw new NotFoundHttpException('Sorry, no Providers with that criteria!');
}
return $emails; }
If I var_dump($this->sendEmailsToProviders('Berlin','Butter' )) ; I get this result

使用dump（）检查$ city和$ product是不是类或数组的字符串。
$city = $email->setCity($form->get('city')->getData());
$product =$email->setProduct($form->get('product')->getData());
也许需要这样
$city = $form->get('city')->getData();
$product =$form->get('product')->getData();
$email->setCity($city);
$email->setProduct($product);
