在Symfony 2.8上傳多張圖片

Question

我正在使用Symfony 2.8，我做了一個表單上傳1張圖片，並且工作正常。但我現在的問題是，我想讓這種形式讓我們有多張照片。 這是我試過的，這是沒有結果！

圖片實體：

<?php 

namespace AppBundle\Entity; 

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

/** 
* Image 
* 
* @ORM\Table(name="image") 
* @ORM\Entity(repositoryClass="AppBundle\Repository\ImageRepository") 
*/ 
class Image 
{ 
    /** 
    * @var int 
    * 
    * @ORM\Column(name="id", type="integer") 
    * @ORM\Id 
    * @ORM\GeneratedValue(strategy="AUTO") 
    */ 
    private $id; 

    /** 
    * @var string 
    * 
    * @ORM\Column(name="path", type="string", length=255) 
    */ 
    private $path; 

    /** 
    * @ORM\Column(type="string") 
    * 
    * @Assert\NotBlank(message="Please, upload the product name as a image file.") 
    * @Assert\File(mimeTypes={ "image/jpg", "image/jpeg" ,"image/png"}) 
    */ 
    private $name; 


    /** 
    * @var \DateTime 
    * 
    * @ORM\Column(name="create_time", type="datetime", nullable=false) 
    */ 
    private $createTime; 

    /** 
    * @var \DateTime 
    * 
    * @ORM\Column(name="change_time", type="datetime", nullable=true) 
    */ 
    private $changeTime; 

    /** 
    * @ORM\ManyToOne(targetEntity="UserBundle\Entity\User", cascade={"persist"}) 
    * @ORM\JoinColumn(referencedColumnName="id", nullable=false) 
    */ 
    private $createUser; 

    /** 
    * @ORM\ManyToOne(targetEntity="UserBundle\Entity\User", cascade={"persist"}) 
    * @ORM\JoinColumn(referencedColumnName="id", nullable=true) 
    */ 
    private $changeUser; 


    /** 
    * Get id 
    * 
    * @return int 
    */ 
    public function getId() 
    { 
     return $this->id; 
    } 


    /** 
    * Set path 
    * 
    * @param string $path 
    * 
    * @return Image 
    */ 
    public function setPath($path) 
    { 
     $this->path = $path; 

     return $this; 
    } 

    /** 
    * Get path 
    * 
    * @return string 
    */ 
    public function getPath() 
    { 
     return $this->path; 
    } 


    /** 
    * @return mixed 
    */ 
    public function getName() 
    { 
     return $this->name; 
    } 

    /** 
    * @param mixed $name 
    */ 
    public function setName($name) 
    { 
     $this->name = $name; 
    } 

    /** 
    * @return \DateTime 
    */ 
    public function getCreateTime() 
    { 
     return $this->createTime; 
    } 

    /** 
    * @param \DateTime $createTime 
    */ 
    public function setCreateTime($createTime) 
    { 
     $this->createTime = $createTime; 
    } 

    /** 
    * @return \DateTime 
    */ 
    public function getChangeTime() 
    { 
     return $this->changeTime; 
    } 

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

    /** 
    * @return mixed 
    */ 
    public function getChangeUser() 
    { 
     return $this->changeUser; 
    } 

    /** 
    * @param mixed $changeUser 
    */ 
    public function setChangeUser($changeUser) 
    { 
     $this->changeUser = $changeUser; 
    } 

    /** 
    * @return mixed 
    */ 
    public function getCreateUser() 
    { 
     return $this->createUser; 
    } 

    /** 
    * @param mixed $createUser 
    */ 
    public function setCreateUser($createUser) 
    { 
     $this->createUser = $createUser; 
    } 



} 

將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) 
     ; 
    } 

    /** 
    * @param OptionsResolver $resolver 
    */ 
    public function configureOptions(OptionsResolver $resolver) 
    { 
     $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

創建倍數上傳您需要在表格類型來創建一個集合類型，讓JavaScript來在前端添加多個上傳。更詳細的你可以檢查文檔。 http://symfony.com/doc/current/reference/forms/types/collection.html

Answer 2

您需要更改這個"multiple" => "multiple"到

'multiple' => true 

你應該有一些像這樣的Symfony2

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