Vichuploaderbundle: fileNameProperty with slug

Created on 17 Aug 2017 · 14Comments · Source: dustin10/VichUploaderBundle

Hi everybody,

I am trying to upload a video from a simple form. My aim is to make the video file be named with the slug of the Entity that I am persisting.

So the entity looks like this:

use Symfony\Component\HttpFoundation\File\File;
use Symfony\Component\HttpFoundation\File\UploadedFile;

/**
 * @var File
 * 
 * @Vich\UploadableField(mapping="participant_video",
 *                       fileNameProperty="videoName")
 */
private $videoFile;


public function setUpdatedAt($updatedAt)
{
    $this->updatedAt = $updatedAt;

    return $this;
}

public function getUpdatedAt()
{
    return $this->updatedAt;
}

public function setVideoFile(UploadedFile $video = null)
{
    $this->videoFile = $video;

    if ($video) {
        // It is required that at least one field changes if you are using doctrine
        // otherwise the event listeners won't be called and the file is lost
        $this->updatedAt = new \DateTime();
    }

    return $this;
}

public function getVideoFile()
{
    return $this->videoFile;
}

public function setVideoName($videoName)
{
    $this->videoName = $videoName;

    return $this;
}

public function getVideoName()
{
    return $this->videoName;
}

and my form is like this:

use Vich\UploaderBundle\Form\Type\VichFileType;

$builder->add('firstName')
        ->add('videoFile', VichFileType::class, array(
            'required' => true,
            'allow_delete' => false));

My config.yml looks like this:

vich_uploader:
    db_driver: orm # or mongodb or propel or phpcr
    mappings:
        participant_video:
            uri_prefix: /participant/video
            upload_destination: '%kernel.root_dir%/../web/video'
            directory_namer: vich.video.namer
            # namer: vich.video.namer
            namer: vich_uploader.namer_uniqid

And to finish my controller:

/**
 * @Route("/{slug}/participant/register", name="register_participant")
 * @Security("has_role('ROLE_USER')")
 */
public function addAction(Request $request, Event $event)
{
    $participant = new Participant();
    $participant->setEvent($event);

    $form = $this->createForm(ParticipantType::class, $participant);
    $form->handleRequest($request);

    if ($form->isValid()) {
        $em = $this->getDoctrine()->getManager();
        $em->persist($participant); // the exception is set here
        $em->flush();

        return $this->redirectToRoute('participant_view', array(
            'slug' => $participant->getSlug()));
    }
    $title = 'Register a new user for "' . $event->getName() . '".';
    return $this->render('participant/form.html.twig', array(
        'title' => $title,
        'event' => $event,
        'form' => $form->createView()));
}

The problems is that when I submit the form, this error happens: The file "" does not exist.

So I am guessing that the slug is not generated yet and so the variable is empty. Am I right?

The stacktrace when I submit the form:

Symfony\Component\HttpFoundation\File\Exception\FileNotFoundException:
The file "" does not exist

That was my error, the problems came from the PHP variables in php.ini: post_max_size and upload_max_filesize which were to low. Sorry for the time taken :/

Is the sluggable working, without file upload?

garak on 17 Aug 2017

Yes it is working well.

paul-mesnilgrente on 17 Aug 2017

is this happening only for a new entity (e.g. create), or also for an old one (e.g. update)?

garak on 18 Aug 2017

It's the same for the update, I have added some code in the issue.
