Hochladen mehrerer Bilder in Symfony 2.8

Question

Ich arbeite an Symfony 2.8, ich habe ein Formular zum Hochladen von 1 Bild gemacht, und es funktioniert gut. Aber das Problem, das ich jetzt habe, ist, dass ich möchte, dass diese Form uns mehrere Bilder erlaubt. Hier ist was ich versucht habe, das war noch ohne Ergebnis!

Bild Einheit:

<?php 

namespace AppBundle\Entity; 

use Doctrine\ORM\Mapping as ORM;

{ 
    /** 
    * @var int 
    * 
    * @ORM\Column(name="id", type="integer") 
    * @ORM\Id

    */ 
    private $id; 

    /**

    private $path;

    private $name;

    } 


    /**

     $this->createTime = $createTime; 
    } 

    /**

    public function getChangeTime() 
    { 
     return $this->changeTime; 
    } 

    /**

    */ 
    public function setChangeTime($changeTime) 
    { 
     $this->changeTime = $changeTime; 
    } 

    /**

Imagetype:

<?php 

namespace AppBundle\Form; 

use Symfony\Component\Form\AbstractType; 
use Symfony\Component\Form\Extension\Core\Type\FileType; 
use Symfony\Component\Form\Extension\Core\Type\SubmitType; 
use Symfony\Component\Form\FormBuilderInterface; 
use Symfony\Component\Form\SubmitButton; 
use Symfony\Component\OptionsResolver\OptionsResolver; 

class ImageType extends AbstractType 
{ 
    /** 
    * @param FormBuilderInterface $builder 
    * @param array $options 
    */ 
    public function buildForm(FormBuilderInterface $builder, array $options) 
    { 
     $builder 
      ->add('name', FileType::class, array("label" => "Files", 
       "required" => FALSE, 
       "attr" => array(
       "multiple" => "multiple"))) 
      ->add('path') 
      ->add('Upload', SubmitType::class) 
     ; 
    }

    { 
     $resolver->setDefaults(array(
      'data_class' => 'AppBundle\Entity\Image' 
     )); 
    } 
} 

ImageController:

public function UploadAction(Request $request) 
{ 

    $product = new Image(); 
    $form = $this->createForm(ImageType::class, $product); 
    $form->handleRequest($request); 


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

     /** @var UploadedFile $file */ 
     $file = $product->getName(); 

     $fileName = md5(uniqid()).'.'.$file->guessExtension(); 


     $file->move(
      '/var/www/html/master_c/web/images/', 
      $fileName 
     ); 

     $product->setName($fileName); 
     $em = $this->getDoctrine()->getManager(); 
     $em->persist($product); 
     $em->flush(); 

    } 

    return $this->render('AppBundle:Image:upload.html.twig', array(
     'form' => $form->createView(), 
    )); 
} 

upload.html.twig:

{{ form_start(form) }} 
    {# ... #} 

    {{ form_row(form.name, { 'attr': {'multiple': 'multiple' }}) }} 
{{ form_end(form) }} 

Answer 1

Erstellen von Multiples laden Sie benötigen eine Sammlung geben Sie in Ihrem Formulartyp erstellen und machen Sie JavaScript mehrere Upload vor Ende hinzuzufügen. Mehr Details können Sie das Dokument überprüfen. http://symfony.com/doc/current/reference/forms/types/collection.html

Answer 2

Sie brauchen diese "multiple" => "multiple" zu

'multiple' => true 

Sie sollten wie diese

->add('name', FileType::class, array("label" => "Files", 'required' => false, 'multiple' => true))
