可捕獲的致命錯誤：傳遞給Doctrine \ Common \ Collections \ ArrayCollection :: __ construct（）的參數1必須是類型數組，對象給定

Question

我在學習Symfony 2，並且在提交表單時出現以下錯誤：

Catchable Fatal Error: Argument 1 passed to Doctrine\Common\Collections\ArrayCollection::__construct() must be of the type array, object given, called in C:\xampp\htdocs\ppe2\vendor\doctrine\orm\lib\Doctrine\ORM\UnitOfWork.php on line 555 and defined

這裏是我的代碼：

控制器：

public function ajouterAction(Request $request){ 

     $sponsor = new Sponsor(); 
     $formulaire = $this->createForm(new SponsorType(), $sponsor)->add('Ajouter', 'submit'); 

     if ($formulaire->handleRequest($request)->isValid()) { 
      $em = $this->getDoctrine()->getManager(); 
      $em->persist($sponsor); 
      $em->flush(); 

      $request->getSession()->getFlashBag()->add('notice', 'Le sponsor a bien été modfié !'); 

      return $this->redirect($this->generateUrl('ffe_sponsor_voir', array('id' => $sponsor->getId()))); 
     } 

     return $this->render('FFESponsorBundle:Sponsor:ajouter.html.twig', array(
      'formulaire' => $formulaire->createView(), 
     )); 
    } 

我的表單類型SponsorType：

public function buildForm(FormBuilderInterface $builder, array $options) 
{ 
    $builder 
     ->add('nom', 'text') 
     ->add('rue', 'text') 
     ->add('codePostal', 'text') 
     ->add('ville', 'text') 
     ->add('telephone', 'text') 
     ->add('mail', 'text') 
     ->add('nomRepresentant', 'text') 
     ->add('typeSponsor', 'entity', array(
       'class'  => 'FFESponsorBundle:TypeSponsor', 
       'property' => 'nom', 
       'multiple' => true 
     )) 
    ; 
} 

我的typeSponsor和Sponsor實體通過ManyToMany關係鏈接。

任何想法有什麼不對？

UPDATE：

這是我的實體：

Answer 1

的問題是，你的$ typeSponsor屬性是ManyToMany關係，但你使用它，如果它是一個ManyToOne或OneToOne關係：

/** 
    * @ORM\ManyToMany(targetEntity="FFE\SponsorBundle\Entity\TypeSponsor", cascade={"persist"}) 
    */ 
private $typeSponsor; 

/** 
* Set typeSponsor 
* 
* @param \FFE\SponsorBundle\Entity\TypeSponsor $typeSponsor 
* @return Sponsor 
*/ 
public function setTypeSponsor(\FFE\SponsorBundle\Entity\TypeSponsor $typeSponsor = null) 
{ 
    $this->typeSponsor = $typeSponsor; 

    return $this; 
} 

/** 
* Get typeSponsor 
* 
* @return \FFE\SponsorBundle\Entity\TypeSponsor 
*/ 
public function getTypeSponsor() 
{ 
    return $this->typeSponsor; 
} 

您應該在屬性註釋中使用它ManyToOne。

編輯：

如果你想使用一個多對多關係，你有你的實體可以改變：

public function __construct() 
{ 
    $this->sponsorType = new \Doctrine\Common\Collection\ArrayCollection(); 
} 

/** 
* Set typeSponsor 
* 
* @param \Doctrine\Common\Collection\ArrayCollection $typeSponsor 
* @return Sponsor 
*/ 
public function setTypeSponsor($typeSponsor) 
{ 
    $this->typeSponsor = $typeSponsor; 

    return $this; 
} 

/** 
* Get typeSponsor 
* 
* @return \Doctrine\Common\Collection\ArrayCollection 
*/ 
public function getTypeSponsor() 
{ 
    return $this->typeSponsor; 
} 

因爲你的領域是TypeSponsor的集合，而不是一個單一的對象。
