Question

我使用优秀的doctrine扩展程序上传。我可以为每个实体上传一个文件，但是如何在同一个实体上传两个不同的文件？

* @Gedmo\Uploadable(path="uploads/articles", appendNumber=true, filenameGenerator="SHA1")
class Article
{
    * @ORM\Column(name="photo", type="string", length=255)
    * @Gedmo\UploadableFilePath
    private $photo

    * @ORM\Column(name="pdf", type="string", length=255)
    * @Gedmo\UploadableFilePath
    private $pdf

在我的控制器上我有：

$uploadableManager->markEntityToUpload($article, $article->getPhoto());
$uploadableManager->markEntityToUpload($article, $article->getPdf());

仅上传最后一个文件并将其保存到数据库中。我怎么能这样做？

Answer 1

你可能会感到困惑。

您的文章实体包含两个字段：照片和pdf，但没有$ materia实体。您可能应该将$ materia更改为$ article。但这不起作用，因为@Uploadable无法为同一个实体上传多个文件。

提示：使用VichUploaderBundle进行Doctrine文件上传处理

UPD：以下是示例类。

<?php

namespace Acme\DemoBundle\Entity;

use Doctrine\ORM\Mapping as ORM;
use Symfony\Component\HttpFoundation\File\File;
use Vich\UploaderBundle\Mapping\Annotation as Vich;

/**
 * @ORM\Entity
 * @ORM\Table(name="article")
 * @Vich\Uploadable
 */
class Article
{
    /**
     * @ORM\Id
     * @ORM\Column(type="integer")
     * @ORM\GeneratedValue(strategy="AUTO")
     */
    private $id;

    // ..... other fields

    /**
     * NOTE: This is not a mapped field of entity metadata, just a simple property.
     *
     * @Vich\UploadableField(mapping="article_photo", fileNameProperty="photoName")
     *
     * @var File
     */
    private $photoFile;

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


    /**
     * NOTE: This is not a mapped field of entity metadata, just a simple property.
     *
     * @Vich\UploadableField(mapping="article_pdf", fileNameProperty="pdfName")
     *
     * @var File
     */
    private $pdfFile;

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

    /**
     * @ORM\Column(type="datetime")
     *
     * @var \DateTime
     */
    private $updatedAt;

    /**
     * @return mixed
     */
    public function getId()
    {

    /**

     */
    public function setPhotoFile(File $photo = null)
    {
        $this->photoFile = $photo;

        if ($photo) {
            // It is required that at least one field changes if you are using doctrine
            // otherwise the event listeners won't be called and the file is lost
            $this->updatedAt = new \DateTime('now');
        }

        return $this;
    }

    public function setPhotoName($photoName)
    {
        $this->photoName = $photoName;

        return $this;
    }

    /**

    public function getPdfFile()

    }

    /**
     * @param string $pdfName

    public function setPdfName($pdfName)

        return $this;

     */
    public function getPdfName()
    {
        return $this->pdfName;
    }
}

你需要以这种方式配置VichUploader：

# app/config/config.yml
vich_uploader:
    db_driver: orm

    mappings:
        article_photo:
            uri_prefix:         /images/articles/photos
            upload_destination: %kernel.root_dir%/../web/images/articles/photos
        article_pdf:
            uri_prefix:         /images/articles/pdfs
            upload_destination: %kernel.root_dir%/../web/images/articles/pdfs

要注意。您可能会对配置，映射，方法感到困惑......只需仔细阅读手册即可。 https://github.com/dustin10/VichUploaderBundle/blob/master/Resources/doc/usage.md
