I would like to upload multiple pictures in my form.
In fact, is working, but only with the small size of the picture ( like less than 1Mo). When I try to upload a picture with 4/5Mo, I have this error: The file "" does not exist

I noticed that it was due to the size because for small images it works very well.

So, my code :
Entity Picture who is related to Activity :

 /**

     * @ORMColumn(type="string")

     * @AssertNotBlank(message="Please, upload the product brochure as a PNG, GIF, JPEG or JPG file.")

     * @AssertFile(mimeTypes = {"image/png","image/jpeg","image/jpg","image/gif"})

     * @AssertFile(maxSize="50M")

     */

    private $url;



    /**

     * @ORMColumn(type="text", nullable=true)

     */

    private $legende;



    /**

     * @ORMColumn(type="datetime")

     */

    private $createdAt;



    /**

     * @ORMManyToOne(targetEntity="AppEntityActivity", inversedBy="pictures")

     */

    private $activity;

The form pictureType :

->add('url', FileType::class, array('label' => 'Image (JPG, JPEG, PNG, GIF)'))

and the controller, in the create activity ( the picture form is here, when you add an activity, you can choose to add one or many pictures )

 /**

     * @Route("/create_activity", name="create_activity")

     */

    public function create_activity(Request $request, ObjectManager $manager){



        $activity = new Activity();

        $form = $this->createForm(ActivityType::class, $activity);

        $form->handleRequest($request);



        if ($form->isSubmitted() && $form->isValid()) {



            $pictures = $activity->getPictures(); // On récupère toutes les photos ajoutées



            if($pictures){ // S'il y a des photos

                foreach ($pictures as $picture ) { // Pour chaque photo

                   $file = $picture->getUrl(); // On récupère l'url uploadé

          // ERROR COMING HERE at $file->guessExtension();

                   $fileName = $this->generateUniqueFileName().'.'.$file->guessExtension(); // On génère un nom de fichier

                   // Move the file to the directory where brochures are stored

                        try {

                            $file->move( // On l'ajoute dans le répertoire

                                $this->getParameter('pictures_directory'),

                                $fileName

                            );

                        } catch (FileException $e) {

                            // ... handle exception if something happens during file upload

                        }

                        $picture->setUrl($fileName);

                }

            }





           $activity->setCreatedAt(new DateTime());

           $activity->setDeleted(0);

           $manager->persist($activity);

           $manager->flush();



        return $this->redirectToRoute('show_activity', ['id' => $activity->getId()]);

        }



        return $this->render('activity/create_activity.html.twig', [

            'formActivity' => $form->createView(),

            'activity' => $activity

        ]);

    }

I made many 'echo; exit;' for know where the error is coming, and she comes from "$file->guessExtension();"

Thanks a lot for your help!

If your $file is an instance of UploadedFile (which it should be in your case), you can use the method $file->getError() to know if there was a problem during the upload of your file.

This method will return an integer corresponding to this documentation : http://php.net/manual/en/features.file-upload.errors.php

In your case, i bet you will have a UPLOAD_ERR_INI_SIZE error.
To solve this, you can see the solution here : Change the maximum upload file size

EDIT

Here's an example for you :

/** @var UploadedFile $file */

$file = $picture->getUrl();



if (UPLOAD_ERR_OK !== $file->getError()) {

    throw new UploadException($file->getErrorMessage());

}
