Multiple Upload Symfony2

Question

I'm beginning with Symfony and I'm stuck with multiple upload.

I can upload just one file and I try to modify this code for multiple upload.

Here's my error :

Expected argument of type "Symfony\Component\HttpFoundation\File\UploadedFile", "array" given

Here's my code :

ImageArticleType:

$builder
        ->add('file', 'file', array('label' => 'Choisir mes images', 'multiple'=> true))
    ;

And my Entity ImageArticle.php

<?php

namespace AD\PlatformBundle\Entity;

use Doctrine\ORM\Mapping as ORM;
use Symfony\Component\HttpFoundation\File\UploadedFile;
use Symfony\Component\Validator\Constraints as Assert;

/**
 * ImageArticle
 *
 * @ORM\Table()
 * @ORM\Entity()
 * @ORM\HasLifecycleCallbacks
 */
class ImageArticle
{
    /**

     *
     * @ORM\Column(name="id", type="integer")
     * @ORM\Id

     */
    private $id;

    /**

    private $alt;

    /**

I was thinking about a simple foreach loop but it doesn't work...

Your error is telling you that you try to pass an array instead of an item of class UploadedFile. Try to remove the multiple options from your field, this may render an array instead. — Jérôme

Thx for your response ! If I remove the multiple option I can't select more than one file. — Wako
– Wako, Commented Aug 8, 2016 at 15:56
Yes I know, but try if you still get the error with only one file. If not your code is correct and i think you should try to make a foreach loop in you controller, to save each file alone. — Jérôme
– Jérôme, Commented Aug 8, 2016 at 15:58
Oh ok. Yes with only one file it work fine. In my controller I persist/flush my Article. I try to have more than one picture with my article so in ArticleType I call ImageArticleType like this ->add('imagearticle', new ImageArticleType(), array('required' => true)). Can't I make a foreach into my ImageArticle Entity ? — Wako

Uploading files with multiple option can be a little bit tricky. With multiple = false option your $file property in your entity class will return single UploadedFile instance, with multiple = true it returns array of UploadedFile instances when you call $entity->getFile(). That's why you have to implement the upload process manually, on form submission, in your action, without lifecycle callbacks. Like this:

Action:

....
$image = new ImageArticle();

$form = $this->createForm('YOUR_FORM', $image);
$form->handleRequest($request);

if ($form->isValid()) {
    ...

    foreach ($image->getFile() as $uploadedFile) {
        $image = new ImageArticle();
        $image
            // setters go here
        ;

        // Upload process go here

        $image->setFile(null);
    }

    $this->get('doctrine.orm.entity_manager')->flush();

    ....
}

Here is a screenshot from my project:

I've got this error

Type error: Argument 3 passed to Symfony\Component\Form\FormFactory::create() must be of the type array, object given, called in /var/www/html/QrCar/src/AD/PlatformBundle/Controller/CarsController.php on line 296

Jérôme Over a year ago

This error is telling you that the $image param of your $this->get('form.factory')->create() in an object instead of an array. Is your images are save in the article entity or another ?

xurshid29 Over a year ago

@Wako createForm() method receives ('String formTypeName', Object dataObject, Array options), I think you're passing an object as a third parameter. Read this

Something like that ?

public function newArticleAction(Request $request)
{
   $article = new Article();
   $article->setUser($this->getUser());

   $imageArticle = new ImageArticle();

   $form = $this->get('form.factory')->create(new \AD\PlatformBundle\Form\ArticleType(), $article, $image); 
    if($form->handleRequest($request)->isValid())
    {
        foreach($imageArticle->getFile() as $imageArticle)
        {
            $imageArticle = new ImageArticle();

            $imageArticle->setAlt($imageArticle->getAlt());
            $imageArticle->setUrl($imageArticle->getUrl());
            $imageArticle->setFile($imageArticle->getFile());

            $imageArticle->preRemoveUpload();
            $imageArticle->preUpload();
            $imageArticle->upload();

        }
        $em = $this->getDoctrine()->getManager();
        $em->persist($article);
        $em->flush();

        $request->getSession()->getFlashBag()->add('notice', 'Article publié ! :)');
        return $this->redirect($this->generateUrl('va_platform_blog'));
    }
    return $this->render('ADPlatformBundle:Cars:newarticle.html.twig', array(
        'form' =>$form->createView(),
    ));
}

Is your images are save in the article entity or another (I'll make changes when I get your answer) ?

I have made some little changes to your code. I'm not sure about all the code but I think this should work

public function newArticleAction(Request $request)
{
   $article = new Article();
   $images = new ImageArticle();

   $form = $this->get('form.factory')->create(ArticleType::class, $article, $images);
   $form->handleRequest($request);

   if($form->isValid())
   {
       $article->setUser($this->getUser());
       // other article fields, if needed

       foreach($images->getFile() as $image)
       {
           $images->setAlt($image->getAlt());
           $images->setUrl($image->getUrl());
           $images->setFile($image->getFile());

           $images->preRemoveUpload();
           $images->preUpload();
           $images->upload();
       }

       $em = $this->getDoctrine()->getManager();
       $em->persist($article);
       $em->flush();

       $request->getSession()->getFlashBag()->add('notice', 'Article publié ! :)');

       return $this->redirect($this->generateUrl('va_platform_blog'));
    }

    return $this->render('ADPlatformBundle:Cars:newarticle.html.twig', [
        'form' => $form->createView(),
    ]);
}

I've got two entity : Article.php and ImageArticle.php

Wako Over a year ago

Same error. Type error: Argument 3 passed to Symfony\Component\Form\FormFactory::create() must be of the type array, object given

Jérôme Over a year ago

During the submit or at the page loading ?

During the page loading

Can you dump the $images in the $form->isValid() ? If this do not work comment the foreach
