Question

如何在使用Doctrine2时访问Symfony2中的ChoiceType（Radiobutton）提交值我正在尝试更新事件实体的eT1和eT2属性的值。来自两个不同ChoiceType（Radiobutton）的输入值在用户提交后存储在eT1和eT2变量中。当我尝试使用$ events-＆gt; setET1（$ eT1）方法时，它会出错 - 注意：未定义的变量：eT1 500内部服务器错误 - ContextErrorException 这是我的控制器代码

以下是用户实体

<?php

namespace AppBundle\Controller;

use AppBundle\Entity\events;
//use AppBundle\Entity\eventtype;
use AppBundle\Entity\users;
use Sensio\Bundle\FrameworkExtraBundle\Configuration\Route;
use Symfony\Bundle\FrameworkBundle\Controller\Controller;
use Symfony\Component\HttpFoundation\Request;
use Symfony\Component\HttpFoundation\Response;
use Symfony\Component\Form\Extension\Core\Type\SubmitType;
use Symfony\Component\Form\Extension\Core\Type\ChoiceType;

class DefaultController extends Controller {

    /**
     * @Route("/home", name="homepage")
     */
    public function indexAction(Request $request) {
        $events = new events();

        $form = $this->createFormBuilder($events)
                ->add('eT1', ChoiceType::class, array(
                    'choices' => array(
                        'Poker' => 1,
                        'Chess' => 2,
                        'Cricket' => 3,
                        'Marbles' => 4,
                        'Football' => 5,
                    ),
                    'choices_as_values' => true,
                    'expanded' => true,
                    'multiple' => false,
                    'label' => 'Choose After Breakfast Event',
                ))
                ->add('eT2', ChoiceType::class, array(
                    'choices' => array(
                        'Poker' => 1,
                        'Chess' => 2,
                        'Cricket' => 3,
                        'Marbles' => 4,
                        'Football' => 5,
                    ),
                    'choices_as_values' => true,
                    'expanded' => true,
                    'multiple' => false,
                    'label' => 'Choose After Snacks Event',
                ))
                ->add('save', SubmitType::class, array('label' => 'Submit'))
                ->getForm();

        if ($request->isMethod('POST')) {
            $form->submit($request);

            $user = $this->container->get('security.context')->getToken()->getUser();
            $events->setUser($user);

            $x = $events->getUser()->getID();

            if ($form->isValid()) {
                //$em = $this->getDoctrine()->getManager();

                $events = $this->getDoctrine()->getRepository('AppBundle:events')->findOneBy(array('user' => $x));
//                var_dump($events);
//                exit;
                if (!$events) {
                    echo 'insert';
                    // tells Doctrine you want to (eventually) save the Product (no queries yet)
                    $em->persist($events);

                    // actually executes the queries (i.e. the INSERT query)
                    $em->flush();
                    return $this->redirectToRoute('homepage');
                } else {
                    echo 'update';
//                    var_dump($form);
//                    exit;
                    $events->setET1($eT1);
                    $events->setET2($eT2);
//                  $em->persist($events);
                    $em->flush();
                    return $this->redirectToRoute('homepage');
                }
            }
        }

        return $this->render('default/index.html.twig', array(
                    'form' => $form->createView(),
        ));
    }

}

下面是定义了setET1（$ eT1）的事件实体

<?php

namespace AppBundle\Entity;

use FOS\UserBundle\Model\User as BaseUser;
use Doctrine\ORM\Mapping as ORM;
use Symfony\Component\Validator\Constraints as Assert;
use Doctrine\Common\Collections\ArrayCollection;

/**
 * users
 *
 * @ORM\Table(name="users")
 * @ORM\Entity(repositoryClass="AppBundle\Repository\usersRepository")
 */
class users extends BaseUser
{
    /**
     * @ORM\Column(name="id", type="integer")
     * @ORM\Id
     * @ORM\GeneratedValue(strategy="AUTO")
     */
    protected $id;

    /**
     * Get id
     * @return integer 
     */
    public function getId()
    {
        return $this->id;
    }

    /**
     * @ORM\OneToOne(targetEntity="events", mappedBy="user")
     */
    protected $event;


//    public function __construct()
//    {
//        parent::__construct(); 
//         }

    }

<强>更新

您的表单将返回已填充的实体，因此您可以执行此操作：

$eventFromForm = $form->getData(); // This is an instance of events()

$events->setET1($eventFromForm->getET1());
$events->setET2($eventFromForm->getET2());

$em->persist($events);
$em->flush();

$ eT1未定义（显然）我猜你正在尝试从表单中获取eT1值，在这种情况下你需要这样做：

$formData = $form->getData();
$events->setET1($formData['eT1']);

注意：未定义的变量：eT1 500内部服务器错误 - ContextErrorException
