OneupUploaderBundle relation between 2 entities - php

Question

I'm new on stackoverflow and I hope you can help me.
I use OneupUploaderBundle on symfony2 and it's working I can upload multiple images and I can persist them in my database.
But now I would like to upload multiple images for one 'Annonce' for exemple so, I have 2 entities
Annonce
namespace TestBundle\Entity;
use Doctrine\ORM\Mapping as ORM;
/**
* Annonce
*
* #ORM\Table(name="annonce")
* #ORM\Entity(repositoryClass="TestBundle\Repository\AnnonceRepository")
*/
class Annonce
{
/**
* #var int
*
* #ORM\Column(name="id", type="integer")
* #ORM\Id
* #ORM\GeneratedValue(strategy="AUTO")
*/
private $id;
/**
* #var string
*
* #ORM\Column(name="titre", type="string", length=255)
*/
private $titre;
/**
* Get id
*
* #return integer
*/
public function getId()
{
return $this->id;
}
/**
* Set titre
*
* #param string $titre
* #return Annonce
*/
public function setTitre($titre)
{
$this->titre = $titre;
return $this;
}
/**
* Get titre
*
* #return string
*/
public function getTitre()
{
return $this->titre;
}
}
And my Entity Image
namespace TestBundle\Entity;
use Doctrine\ORM\Mapping as ORM;
/**
* Image
*
* #ORM\Table(name="image")
* #ORM\Entity(repositoryClass="TestBundle\Repository\ImageRepository")
*/
class Image
{
/**
* #var int
*
* #ORM\Column(name="id", type="integer")
* #ORM\Id
* #ORM\GeneratedValue(strategy="AUTO")
*/
private $id;
/**
* #var string
*
* #ORM\Column(name="name", type="string", length=255)
*/
private $name;
/**
* Get id
*
* #return integer
*/
public function getId()
{
return $this->id;
}
/**
* Set name
*
* #param string $name
* #return Image
*/
public function setName($name)
{
$this->name = $name;
return $this;
}
/**
* Get name
*
* #return string
*/
public function getName()
{
return $this->name;
}
/**
* #ORM\ManyToOne(targetEntity="TestBundle\Entity\Annonce")
* #ORM\JoinColumn(nullable=false)
*/
private $annonce;
/**
* Set annonce
*
* #param \TestBundle\Entity\Annonce $annonce
* #return Image
*/
public function setAnnonce(\TestBundle\Entity\Annonce $annonce)
{
$this->annonce = $annonce;
return $this;
}
/**
* Get annonce
*
* #return \TestBundle\Entity\Annonce
*/
public function getAnnonce()
{
return $this->annonce;
}
}
My EventListener
namespace TestBundle\EventListener;
use Doctrine\Common\Persistence\ObjectManager;
use Oneup\UploaderBundle\Event\PostPersistEvent;
use TestBundle\Entity\Annonce;
use TestBundle\Entity\Image;
class UploadListener
{
/**
* #var ObjectManager
*/
private $em;
public function __construct(ObjectManager $em)
{
$this->em = $em;
}
public function onUpload(PostPersistEvent $event)
{
$file = $event->getFile();
$annonce = new Annonce();
$image = new Image();
/* TEST */
$annonce->setTitre("I'am a title");
$this->em->persist($annonce);
$image->setName($file->getFilename());
$image->setAnnonce($annonce);
$this->em->persist($image);
$this->em->flush();
$response = $event->getResponse();
$response['files'] = [
'name' => $file->getFilename(),
'size' => $file->getSize()
];
}
The problem is, when I upload many images, I have the same number of row in Annonce as in Image.
Someone can help me please :)
