Question

我尝试构建一个用于创建实体Campaign的表单，我可以在其中链接用户。问题是当我坚持竞选实体时，连接表中没有任何事情发生。

以下是广告系列实体的摘录：

/**
 * Campaign
 *
 * @ORM\Table(name="campaign")
 * @ORM\Entity(repositoryClass="AppBundle\Repository\CampaignRepository")
 * @ORM\HasLifecycleCallbacks
 */
class Campaign
{
/**
 * @ORM\ManyToMany(targetEntity="User", mappedBy="campaigns", cascade={"all"})
 */
private $players;

/**
 * Add players
 *
 * @param \AppBundle\Entity\User $players
 * @return Campaign
 */
public function addPlayer(\AppBundle\Entity\User $players)
{
    $players->addCampaign($this);
    $this->players[] = $players;

    return $this;
}

/**
 * Remove players
 *
 * @param \AppBundle\Entity\User $players
 */
public function removePlayer(\AppBundle\Entity\User $players)
{
    $this->players->removeElement($players);
}

/**
 * Get players
 *
 * @return \Doctrine\Common\Collections\Collection 
 */
public function getPlayers()
{
    return $this->players;
}
}

以下是用户实体的摘录：

/**
 * @ORM\Entity
 * @ORM\Table(name="fos_user")
 * @ORM\HasLifecycleCallbacks
 */
class User extends \FOS\UserBundle\Model\User
{
/**
 * @ORM\ManyToMany(targetEntity="Campaign", inversedBy="players", cascade={"all"})
 * @ORM\JoinTable(name="users_campaigns")
 */
protected $campaigns;

/**
 * Add campaign
 *
 * @param \AppBundle\Entity\Campaign $campaign
 * @return User
 */
public function addCampaign(\AppBundle\Entity\Campaign $campaign)
{
    $campaign->addPlayer($this);
    $this->campaigns[] = $campaign;

    return $this;
}

/**
 * Remove campaign
 *
 * @param \AppBundle\Entity\Campaign $campaign
 */
public function removeCampaign(\AppBundle\Entity\Campaign $campaign)
{
    $this->campaigns->removeElement($campaign);
}

/**
 * Get campaign
 *
 * @return \Doctrine\Common\Collections\Collection 
 */
public function getCampaign()
{
    return $this->campaigns;
}
}

这是我的表单类型：

class NewCampaignFormType extends AbstractType
{
public function buildForm(FormBuilderInterface $builder, array $options)
{
    $builder
        ->add('name', 'text', array(
        "label" => 'form.name',
        'required' => true,
        ))
        ->add('description','ckeditor',array(
            "label" => 'form.description',
            "required" => true,
        ))
        ->add('players','entity',array(
            'label'=>'form.campaign.players',
            'class'=> 'AppBundle\Entity\User',
            'multiple' => true,
        ));
}

public function getName()
{
    return 'campaign';
}

public function configureOptions(OptionsResolver $resolver)
{
    $resolver->setDefaults(array(
        'data_class' => 'AppBundle\Entity\Campaign',
    ));
}
}

最后，这是我的控制器：

 public function createAction(Request $request){
    $em = $this->getDoctrine()->getManager();
    $campaign = new Campaign();

    $form = $this->createForm(new NewCampaignFormType(),$campaign);
    $form->handleRequest($request);

    if ($form->isSubmitted() && $form->isValid())
    {
        $user = $this->getUser();
        $campaign->setMJ($user->getId());
        $players = $form->get('players');
        var_dump($players);
        $em->persist($campaign);
        $em->flush();
        return $this->redirectToRoute('show_campaign', array('id'=>$campaign->getId()));
    }

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

我现在已经坚持了很长一段时间，所以任何有想法的人都试试吧。

您处理的Campain对象不属于该关系的一方，因此默认情况下它不会被Doctrine检查和保留。

像这里改变关系的一面：

运动

/**
 * @ORM\ManyToMany(targetEntity="User", inversedBy="campaigns" , cascade={"all"})
 * @ORM\JoinTable(name="users_campaigns")
 */
private $players;

用户

/**
 * @ORM\ManyToMany(targetEntity="Campaign", mappedBy="players", cascade={"all"})
 */
protected $campaigns;
