在 Symfony2 中使用 VlabsMediaBundle 上传多个文件

Question

我正在尝试使用 vlabsmediaBundle 在一个实体上制作多个上传文件。所以我有一则广告可以有很多图片，但每张图片只能与一个广告链接。我遵循了捆绑包的教程（tuto），但出现错误。

此处：

Entity Image.php

namespace MDB\PlatformBundle\Entity;

use Doctrine\ORM\Mapping as ORM;
use Vlabs\MediaBundle\Entity\BaseFile as VlabsFile;
use Symfony\Component\Validator\Constraints as Assert;

/**
 * Image
 *
 * @ORM\Table()
 * @ORM\Entity
 */
class Image extends VlabsFile {



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

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

    /**
     * @ORM\ManyToOne(targetEntity="MDB\AnnonceBundle\Entity\Annonce", inversedBy="images")
     * @ORM\JoinColumn(nullable=true)
     */
    private $annonce;

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

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

        return $this;
    }

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

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

        return $this;
    }

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

    public function getAnnonce() {
        return $this->annonce;
    }

    public function setAnnonce($annonce) {
        $this->annonce = $annonce;
    }

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

    /**
     * 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;
    }

}

}

我有以下错误：Catchable Fatal Error: Argument 1 passed to Vlabs\MediaBundle\EventListener\BaseFileListener::preSetData() must be an instance of Symfony\Component\Form\Event\DataEvent, instance of Symfony\Component\Form\FormEvent given in C:\wamp\www\Mdb\vendor\vlabs\media-bundle\Vlabs\MediaBundle\EventListener\BaseFileListener.php line 59

我试图改变这一行：

->add('image', 'vlabs_file', array(
                'required' => false
            ))

与：

->add('images', 'collection', array('type' => 'vlabs_file'))

但我只有在这种情况下出现的图像标签

如果有人有想法？

Answer 1

我对您的问题进行了一些调查，Vlabs Media Bundle 似乎无人维护。 PRE_SET_DATA 事件 (Vlabs\MediaBundle\EventListener\BaseFileListener::preSetData()) 上的表单侦听器与新版本的 Symfony 不兼容（它期望 DataEvent 作为参数而不是 FormEvent）。他们 fixed it but after 1.1.1 release（您可以比较链接中的日期）。如果真的想尝试一下，请更改 composer.json 和运行作曲家更新。我不能保证不会有其他可能的问题。

composer.json

"vlabs/media-bundle": "dev-master"

库更新

composer update vlabs/media-bundle
