Update entity file field - php

Question

I have some issues with the update of an entity with a file field on it. I don't know what it can be, because I did that a lot of time, but today it won't work.
So this is the entity:
<?php
namespace AppBundle\Entity;
use Doctrine\ORM\Mapping as ORM;
use Symfony\Component\Validator\Constraints as Assert;
/**
* Consigli
*
* #ORM\Table()
* #ORM\HasLifecycleCallbacks
* #ORM\Entity(repositoryClass="AppBundle\Entity\Repository\ConsigliRepository")
*/
class Consigli
{
/**
* #var integer
*
* #ORM\Column(name="id", type="integer")
* #ORM\Id
* #ORM\GeneratedValue(strategy="AUTO")
*/
private $id;
/**
* #var string
*
* #ORM\Column(name="titolo", type="string", length=255)
*/
private $titolo;
/**
* #var string
*
* #ORM\Column(name="testo", type="text")
*/
private $testo;
/**
* #var string $image
* #Assert\File( maxSize = "60000000", mimeTypesMessage = "Perfavore inserisci un'immagine valida!")
* #ORM\Column(name="image", type="string", length=255, nullable=true)
*/
private $image;
/**
* #ORM\ManyToOne(targetEntity="Categoria", inversedBy="categoria")
* #ORM\JoinColumn(name="categoria_id", referencedColumnName="id")
*/
protected $categoria;
/**
* #var date
*
* #ORM\Column(name="data", type="date")
*/
public $data;
/**
* Get id
*
* #return integer
*/
public function getId()
{
return $this->id;
}
/**
* Set titolo
*
* #param string $titolo
*
* #return Consigli
*/
public function setTitolo($titolo)
{
$this->titolo = $titolo;
return $this;
}
/**
* Get titolo
*
* #return string
*/
public function getTitolo()
{
return $this->titolo;
}
/**
* Set testo
*
* #param string $testo
*
* #return Consigli
*/
public function setTesto($testo)
{
$this->testo = $testo;
return $this;
}
/**
* Get testo
*
* #return string
*/
public function getTesto()
{
return $this->testo;
}
/**
* Set image
*
* #param string $image
*/
public function setImage($image)
{
$this->image = $image;
}
/**
* Get image
*
* #return string
*/
public function getImage()
{
return $this->image;
}
public function getFullImagePath() {
return null === $this->image ? null : $this->getUploadRootDir(). $this->image;
}
protected function getUploadRootDir() {
// the absolute directory path where uploaded documents should be saved
return $this->getTmpUploadRootDir().$this->getId()."/";
}
protected function getTmpUploadRootDir() {
// the absolute directory path where uploaded documents should be saved
return __DIR__ . '/../../../web/immaginiConsigli/';
}
/**
* #ORM\PrePersist()
* #ORM\PreUpdate()
*/
public function uploadImage() {
// the file property can be empty if the field is not required
if (null === $this->image) {
return;
}
if(!$this->id){
$this->image->move($this->getTmpUploadRootDir(), $this->image->getClientOriginalName());
}else{
return null;
}
$this->setImage($this->image->getClientOriginalName());
}
/**
* #ORM\PostPersist()
*/
public function moveImage()
{
if (null === $this->image)
{
return;
}
if (!is_dir($this->getUploadRootDir()))
{
mkdir($this->getUploadRootDir());
}
copy($this->getTmpUploadRootDir() . $this->image, $this->getFullImagePath());
unlink($this->getTmpUploadRootDir() . $this->image);
}
/**
* Set data
*
* #param \DateTime $data
*
* #return Consigli
*/
public function setData($data)
{
$this->data = $data;
return $this;
}
/**
* Get data
*
* #return \DateTime
*/
public function getData()
{
return $this->data;
}
/**
* Set categoria
*
* #param \AppBundle\Entity\Categoria $categoria
*
* #return Consigli
*/
public function setCategoria(\AppBundle\Entity\Categoria $categoria = null)
{
$this->categoria = $categoria;
return $this;
}
/**
* Get categoria
*
* #return \AppBundle\Entity\Categoria
*/
public function getCategoria()
{
return $this->categoria;
}
}
The file is stored in a folder, that is as you can see "immaginiConsigli", and in the table of the database I have the "image" field, that stores the name of the image.
The update action in the controller is:
public function modificaconsiglioAction(Request $request, $id)
{
$em = $this->getDoctrine()->getManager();
$consiglio = $em->getRepository('AppBundle:Consigli')->find($id);
$form = $this->createForm(new ConsiglioType($consiglio), $consiglio);
$form->handleRequest($request);
if ($form->isValid())
{
$em = $this->getDoctrine()->getManager();
try
{
$em->persist($consiglio);
$em->flush();
return $this->redirect($this->generateUrl('successconsigliomodificato'));
} catch (\Exception $e)
{
$form->addError(new FormError('errore nel database: ' . $e->getMessage()));
}
if ($form->isValid())
{
$var = $consiglio;
$em->persit($var);
$em->flush();
return $this->redirect($this->generateUrl('successconsigliomodificato'));
} else
{
}
}
return $this->render('adminarea/modificaconsiglio.html.twig', array(
'consiglio' => $consiglio,
'form' => $form->createView()));
}
So what happens is: I want to update an already existing record, that of course has already the file in it. The update seems to work, but when I render the new and updated record, the image doesn't show, and in the database I always get something like this:
/tmp/php1QyeYr
That is not the name of the image.
And also, the new file/image, it isn't inserted in the folder.
So, anyone knows what I'm doing wrong?

after looking again, I think I see the problem.
Your query will return an array of matched entities, not the match itself. You need to call findOneBy instead.
public function modificaconsiglioAction( Request $request, $id ) {
$em = $this->getDoctrine()
->getManager();
$consiglio = $em->getRepository( 'AppBundle:Consigli' )
->findOneBy( [ 'id' => $id ] );
if ( null !== $consiglio ) {
$form = $this->createForm( new ConsiglioType( $consiglio ), $consiglio );
$form->handleRequest( $request );
if ( $form->isSubmitted() && $form->isValid() ) {
$em->persist( $consiglio );
$em->flush();
return $this->redirect( $this->generateUrl( 'successconsigliomodificato' ) );
}
} else {
// do something about letting the user know the id matched nothing
}
return $this->render( 'adminarea/modificaconsiglio.html.twig', [
'consiglio' => $consiglio,
'form' => $form->createView(),
] );
}
Its also worth noting that you can get away without making your own query to the database. If you change your method signature to:
public function modificaconsiglioAction( Request $request, Consigli $consigli ) {
Symfony will automatically query the database for you based on the $id sent to the controller in the route.
