Edit an entity contains an file field - php

Question

I have created an entity Article, with a field image. Eveything is working fine, but when I try to update and edit an article, I got the oldest fields like titre but not the image field. I got an empty image and I have to upload a new image. I want to get the oldest picture, btw, I have the path of the picture stored on the db.
This is my form ArticleType.php
<?php
namespace RoubBundle\Form;
use Symfony\Component\Form\AbstractType;
use Symfony\Component\Form\FormBuilderInterface;
use Symfony\Component\OptionsResolver\OptionsResolver;
use Symfony\Component\Form\Extension\Core\Type\FileType;
class ArticleType extends AbstractType
{
/**
* #param FormBuilderInterface $builder
* #param array $options
*/
public function buildForm(FormBuilderInterface $builder, array $options)
{
$builder
->add('titre')
->add('image', 'file')
;
}
/**
* #param OptionsResolver $resolver
*/
public function configureOptions(OptionsResolver $resolver)
{
$resolver->setDefaults(array(
'data_class' => 'RoubBundle\Entity\Article'
));
}
}
This is my entity article.php:
<?php
namespace RoubBundle\Entity;
use Doctrine\ORM\Mapping as ORM;
use Symfony\Component\Validator\Constraints as Assert;
/**
* Article
*
* #ORM\Table(name="article")
* #ORM\Entity(repositoryClass="RoubBundle\Repository\ArticleRepository")
*/
class Article
{
/**
* #var int
*
* #ORM\Column(name="id", type="integer")
* #ORM\Id
* #ORM\GeneratedValue(strategy="AUTO")
*/
private $id;
/**
* #ORM\Column(type="string")
*
* #Assert\NotBlank(message="Veuillez mettre vos images.")
* #Assert\File(
* maxSize="5242880",
* mimeTypes = {
* "image/png",
* "image/jpeg",
* "image/jpg",
* "image/gif"
* }
* )
*/
private $image;
/**
* #ORM\Column(type="string")
* #var string
*/
private $titre;
public function getTitre()
{
return $this->titre;
}
public function setTitre($titre)
{
$this->titre = $titre;
return $this;
}
public function getImage()
{
return $this->image;
}
public function setImage($image)
{
$this->image = $image;
return $this;
}
/**
* Get id
*
* #return integer
*/
public function getId()
{
return $this->id;
}
}
And this is in my ArticleController.php:
public function editAction(Request $request, Article $article)
{
$article->setImage(
new File($this->getParameter('images_directory').'/'.$article->getImage()));
$deleteForm = $this->createDeleteForm($article);
$editForm = $this->createForm('RoubBundle\Form\ArticleType', $article);
$editForm->handleRequest($request);
if ($editForm->isSubmitted() && $editForm->isValid()) {
$em = $this->getDoctrine()->getManager();
$em->persist($article);
$em->flush();
return $this->redirectToRoute('article_edit', array('id' => $article->getId()));
}
return $this->render('RoubBundle:article:edit.html.twig', array(
'article' => $article,
'edit_form' => $editForm->createView(),
'delete_form' => $deleteForm->createView(),
));
}
If someone can help me, and thank you a lot for being here, and read my problem until here <3

Answer 1

Keep a clone of your image somewhere at the start of your function, before handling the request :
public function editAction(Request $request, Article $article)
{
$originalImage = clone $article->getImage();
// .. rest of your function here
And when your form is valid, check if you have a new image, if not, set the old one back:
if ($editForm->isSubmitted() && $editForm->isValid()) {
if ($article->getImage()) {
$article->setImage($originalImage);
}
$em = $this->getDoctrine()->getManager();
$em->persist($article);
$em->flush();
return $this->redirectToRoute('article_edit', array('id' => $article->getId()));
}
It's pseudo code, but you get the idea. I'm using clone here in case you have a reference to an object, but if it's just a path you can simply assign the value.
EDIT : Clarify where stuff should go
