use Doctrine\ORM\Mapping as ORM;
use Symfony\Component\Validator\Constraint as Assert;
use Doctrine\Common\Collections\ArrayCollection;
/**
* Imagem
*
* #ORM\Table()
* #ORM\Entity(repositoryClass="NoticiaBundle\Repository\ImagemRepository")
* #ORM\HasLifecycleCallbacks
*/
class Imagem
{
/**
* #var integer
*
* #ORM\Column(name="id", type="integer")
* #ORM\Id
* #ORM\GeneratedValue(strategy="AUTO")
*/
private $id;
/**
* #ORM\Column(type="string", length=255, nullable=true)
*/
public $path;
/**
* #ORM\OneToMany(targetEntity="Noticia", mappedBy="imagem")
*/
private $noticias = array();
public function __construct()
{
$this->noticias = new ArrayCollection();
}
public $file;
public function getUploadRootDir()
{
return __dir__.'/../../../../web/uploads';
}
public function getAbsolutePath()
{
return null === $this->path ? null : $this->getUploadRootDir().'/'.$this->path;
}
/**

*/
public function preUpload()
{
$this->tempFile = $this->getAbsolutePath();
$this->oldFile = $this->getPath();
if(null !== $this->file) $this->path = sha1(uniqid(mt_rand(),true)).'.'.$this->file->guessExtension();
}
/**

Noticia FormType
<?php

*/
public function novoAction(Request $request)

return $this->redirect($this->generateUrl('noticias_index'));
} catch (\Exception $e) {
$this->get('session')->getFlashBag()->add(
'danger', $e->getMessage()
);
}
}
return $this->render("NoticiaBundle:Noticia:formulario.html.twig",
array('form' => $form->createView()));
}
I change my entity upload file and now he is saving the right path, but the file is bot saving into the project directory

Answer 1

There is no easy way to test your code but just looking at it, the most obvious issue I see is that you don't call the function preUpload before saving the file.
You may need the following annotation for the preUpload function.
/**
* #ORM\PrePersist()
* #ORM\PreUpdate()
*/
