i wanna add a file field in my [symfony2.5] form.
I want to open the file explorer to select a file , and display his path in the view like :
"C://path/to/file.docx"
I dont want to upload a image or whatever, just the path string.
i just added that attribute in my Advert Entity :
/**
* @var string
*
* @ORM\Column(type="text", length=255, nullable=false)
* @Assert\NotBlank(message="Please, upload the product brochure as a PDF file.")
*/
private $attachment;
/**
* Set attachment
*
* @param string $attachment
* @return Advert
*/
public function setAttachment($attachment)
{
$this->title = $attachment;
return $this;
}
/**
* Get attachment
*
* @return string
*/
public function getAttachment()
{
return $this->title;
}
in my Form/AdvertType.php i've added :
->add('attachment', 'file')
Here is my addAction :
public function addAction(Request $request)
{
$advert = new Advert();
$form = $this->createForm(new AdvertType(), $advert);
$usr = $this->get('security.context')->getToken()->getUser();
if ($form->handleRequest($request)->isValid()) {
$em = $this->getDoctrine()->getManager();
$advert->setAuthor($usr->getUsername());
$advert->setDate(new \DateTime);
$em->persist($advert);
$em->flush();
$request->getSession()->getFlashBag()->add('info', 'Annonce bien enregistrée.');
// On redirige vers la page de visualisation de l'annonce nouvellement créée/
return $this->redirect($this->generateUrl('info_view', array('id' => $advert->getId())));
}
return $this->render('SocietyPerfclientBundle:Default:add.html.twig', array(
'form' => $form->createView(),
));
}
My @Assert\NotBlank(message="Please, upload the product brochure as a PDF file.") is always here..
Got this error : 
I dont understand whats wrong please help me..
