Symfony媒体包。该包允许以简单的方式上传文件。该包需要配合dropzone.js脚本工作。

配置

使用composer安装包

$ composer require app-verk/media-bundle

在kernel中启用包

<?php
// app/AppKernel.php

public function registerBundles()
{
    $bundles = array(
        // ...
        new AppVerk\MediaBundle\MediaBundle(),
        // ...
    );
}

创建你的媒体类

<?php

namespace AppBundle\Entity;

use AppVerk\MediaBundle\Entity\Media as BaseMedia;
use Doctrine\ORM\Mapping as ORM;

/**
 * @ORM\Entity()
 */
class Media extends BaseMedia
{

}

添加到config.yml

twig:
    form:
        resources:
            - 'MediaBundle:form:fields.html.twig'
            
media:
    entities:
        media_class: AppBundle\Entity\Media
    allowed_mime_types: ["image/jpeg", "image/jpg", "image/png", "image/gif", "application/pdf"]

添加到routing.yml

media:
    resource: '@MediaBundle/Controller/'
    type: annotation

将这些库添加到你的管理面板

<!--css -->
<link rel="stylesheet" href="{{ asset('bundles/media/css/dropzone.min.css') }}" />

<!-- js -->
<script src="{{ asset('bundles/media/js/dropzone.min.js') }}"></script>

更新数据库模式

$ php app/console doctrine:schema:update --force

媒体表单类型

<?php

use Symfony\Component\Form\AbstractType;
use AppVerk\MediaBundle\Form\Type\MediaType;
use Symfony\Component\Form\FormBuilderInterface;

class Post extends AbstractType
{
    public function buildForm(FormBuilderInterface $builder, array $options)
    {
        $formMapper
            ->add('image', MediaType::class)
        ;
    }
}

Twig辅助函数

渲染媒体

<img src="{{ post.media|media }}" />

验证组

包允许以不同方式验证每个使用的MediaType。例如，你想只允许PDF文件

你需要将组添加到config.yml中

media:
    entities:
        media_class: AppBundle\Entity\Media
    allowed_mime_types: ["image/png", "image/gif"]
    max_file_size: 15000000
    groups:
        lorem:
            allowed_mime_types: ["application/pdf"]
            max_file_size: 560000

在MediaType中设置组

$formMapper->add('image', MediaType::class, [
    'group' => 'lorem'
]);
