我正在研究Symfony2.8，我想在我的产品控制器的createAction中上传图像但我无法获取FileUpload对象来移动文件服务器。我只能将fileName作为字符串访问。

的appbundle /实体/图像

<?php
namespace AppBundle\Entity;

use Doctrine\ORM\Mapping as ORM;

/**
 * Image
 *
 * @ORM\Table(name="app_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="imageName", type="string", length=255, unique=true, nullable=true)
     * 
     */
    private $imageName;

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

/**
 * Set imageName
 * @param string $imageName
 * @return Image
 */
public function setImageName($imageName)
{
    $this->imageName = $imageName;
    return $this;
}

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

/**
 * Set isLocked
 * @param boolean $isLocked
 * @return Image
 */
public function setIsLocked($isLocked)
{
    $this->isLocked = $isLocked;
    return $this;
}

/**
 * Get isLocked
 * @return bool
 */
public function getIsLocked()
{
    return $this->isLocked;
}

public function getUrl(){
    if($this->imageName == null || $this->imageName == "" || $this->imageName == self::DEFAULT_NAME){
        $imgName = self::DEFAULT_NAME;
    }else{
        $imgName = $this->imageName;
    }
    return getcwd().'/uploads/images/'.$imgName;
}
}

的appbundle /实体/ ShopProduct 

<?php

在我的控制器中，我根据产品的自定义表单创建了Form。产品

的appbundle /控制器/ ProductController.php 

public function createAction(Request $request){
    $user = $this->get('security.context')->getToken()->getUser();

    $em         = $this->getDoctrine()->getManager();
    $shop       = $em->getRepository('AppBundle:Shop')->findOneBy(array("owner"=>$user->getId()));

    $shopProduct = new ShopProduct($shop);

    $form = $this->createForm(ShopProductType::class, $shopProduct);
    $form->handleRequest($request);

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

            $shopProduct    = $form->getData();

            $image = $shopProduct->getImage()->getImageName();
            if($image != null){
                $fileName = 'sprod_'.$shop->getId().'_'.md5(uniqid()).$image->guessExtension();
                $image->move($this->getParameter('produits_directory'), $fileName);
                $shopProduct->getImage()->setImageName($fileName);
            }

            $em->persist($shopProduct);
            $em->flush();           
            return $this->redirectToRoute('pro_product');
        }
    }

    return $this->render('BoBundle:Products:new-product.html.twig', array(
            "form" => $form->createView()
    ));
}

问题是，当我按照Symfony2 documentation for the file uploads中的说明尝试使用我的文件时，我收到错误消息：

  

在字符串

上调用成员函数guessExtension（）

imageName属性是表单发送的图像的名称，在我的例子中，它应该是FileUpload对象。

的appbundle /形式/ ShopProductType.php 

<?php
namespace AppBundle\Form;
use AppBundle\Form\ImageType;

class ShopProductType extends AbstractType
{
    public function buildForm(FormBuilderInterface $builder, array $options)
    {
        $builder
            ->add('image', ImageType::class, array('required' => false))
            //etc
    }
}

//的appbundle /形式/ ImageType.php 

use Symfony\Component\Form\Extension\Core\Type\FileType;

class ImageType extends AbstractType
{
    public function buildForm(FormBuilderInterface $builder, array $options)
    {
        $builder
            ->add('imageName', FileType::class, array('label' => 'Logo' , 'attr' => array('accept' , 'image/x-png,image/gif,image/jpeg,image/jpg')));
    }

编辑：

这是我的表单视图：

<form id="login-form" action="{{ path("pro_product_create") }}" method="post">
    {{ form_errors(form) }}
    {{ form_widget(form._token) }}
    <div class="row">
        <div class="form-group">
        <label for="appbundle_shopproduct_image_imageName" class="form-label">Image produit</label><br>
        <div class="modal-astuce">
            <i>Si vous ne choisissez pas d’image, par défaut nous en sélectionnerons une dans notre banque d’images en fonction du nom du produit.</i>
        </div>
        <div class="row row-image-product">
            <a class="greybtn abtn upload-img-btn" onClick="$('#appbundle_shopproduct_image_imageName').trigger('click');selectimg('1');">
            <i class="fa fa-upload" aria-hidden="true" style="margin-right: 15px;"></i>Uploader une image
            </a>
            <i id="check1" class="fa fa-check" aria-hidden="true"></i><br/>
        </div>
            <span id="filename"></span>
            <input  type="file" id="appbundle_shopproduct_image_imageName" name="appbundle_shopproduct[image][imageName]" accept="image/x-png,image/gif,image/jpeg,image/jpg" style="display:none">
        </div>
    </div>        
    <div class="row">
        {{ form_row(form.name) }}
    </div>        
    <div class="row center row-submit">
        <input class="btn-yellow" id="" name="_submit" type="submit" value="Valider">
    </div>
</form>

问题出在表单属性中。要上传文件，我们必须在表单中添加enctype="multipart/form-data"。

我只需更正添加enctype的表单：

<form id="login-form" action="{{ path("pro_product_create") }}" method="post" {{ form_enctype(form) }}>

更好的方法是使用{{ form_start(form) }}打印表单，因为生成了关于表单中包含的输入类型的enctype：

{{ form_start(form) }}
     <!-- Form content -->
{{ form_end(form) }}
