当我尝试将多个图像上传到数据库时出现问题。我已经阅读了 symfony 文档，每次可以上传一张图片。我还阅读了
http://symfony.com/doc/current/cookbook/form/form_collections.html
到现在为止，我完全理解了上传一张图片的过程，但是当你需要上传多张图片时会发生什么？这是我的情况，我有一个 Store 实体和一个 StorePhoto 实体，一个 Store 包含与 StorePhoto(variable commerce_photos) 的 OneToMany 关系，（我正在为商店开发某种图片库。）这个想法是上传多个一次图片，我的意思是选择多个文件并上传它们。这是我所做的
我的商店实体
<?php

protected $commerce_photos;
public function __construct(){
$this->commerce_photos = new ArrayCollection();
}

public function getId()

我的 StorePhoto 实体

}
public function upload()

//the file property can be empty if the field is not required
if(null === $this->getImageFile())
{
return;
}
//use the original file name here but you should
//sanitaze it at least to avoid any security issues
//move takes the target directory and then the target filename to move to.
$this->getImageFile()->move(
$this->getUploadRootDir(), $this->getImageFile()->getClientOriginalName()

$this->path = $this->getImageFile()->getClientOriginalName();

我的控制器
<?php
namespace AppBundle\Controller;
use Sensio\Bundle\FrameworkExtraBundle\Configuration\Route;
use Symfony\Bundle\FrameworkBundle\Controller\Controller;
use AppBundle\Forms\Type\FileUploadType;
use Symfony\Component\HttpFoundation\Request;
use AppBundle\Entity\StorePhoto;
use AppBundle\Entity\Store;
use Symfony\Component\HttpFoundation\Response;
use AppBundle\Forms\Type\MultipleFileUploadType;
class DefaultController extends Controller
{
public function multipleFileUploadAction(Request $request)
{
$store = new Store();
$store->setName('Test01');
$store->addCommercePhotos(new StorePhoto());
$form = $this->createForm(new MultipleFileUploadType(),$store);
$form->handleRequest($request);
if($form->isValid())
{
$em = $this->getDoctrine()->getManager();
$em->persist($store);
$em->flush();
return new Response('200 OK...');
}
return $this->render('Forms/FileUpload.html.twig',array('form'=>$form->createView()));
}
}
我现在的表单，FileUploadType 和 MultipleFileUploadType
<?php
namespace AppBundle\Forms\Type;
use Symfony\Component\Form\AbstractType;
use Symfony\Component\Form\FormBuilderInterface;
use Symfony\Component\OptionsResolver\OptionsResolverInterface;
class FileUploadType extends AbstractType
{
public function buildForm(FormBuilderInterface $builder, array $options)
{
$builder->add('imageName', 'text');
$builder->add('imageFile', 'file',
array('multiple'=>'multiple'));
// $builder->add('Save', 'submit');
}
public function getName()
{
return "storePhoto";
}
public function setDefaultOptions(OptionsResolverInterface $resolver)
{
$resolver->setDefaults(array(
'data_class' => 'AppBundle\Entity\StorePhoto',
));
}
}
?>
<?php
namespace AppBundle\Forms\Type;
use Symfony\Component\Form\AbstractType;
use Symfony\Component\Form\FormBuilderInterface;
use Symfony\Component\OptionsResolver\OptionsResolverInterface;
use AppBundle\Forms\Type\FileUploadType;
class MultipleFileUploadType extends AbstractType
{
public function buildForm(FormBuilderInterface $builder, array $options)
{
$builder->add('name','text');
$builder->add('commerce_photos', 'collection',array(
'type' => new FileUploadType()));
$builder->add('Save', 'submit');
}
public function getName()
{
return "MultipleFileUpload";
}
public function setDefaultOptions(OptionsResolverInterface $resolver)
{
$resolver->setDefaults(array(
'data_class' => 'AppBundle\Entity\Store',
));
}
}
?>
这就是所有的代码，我不知道我是否在这里遗漏了什么。我需要做的是显示对话框，选择几张图像然后保存它们。在这种情况下，在控制器中我写了这一行
$store = new Store();
$store->setName('Test01');
$store->addCommercePhotos(new StorePhoto());
在这种情况下，当我呈现表单时，它会显示一个对话框，并且只允许我选择一个文件。如果我删除第三行， addCommerce... 它只显示标签 commercePhotos。
提前致谢！
