Question

I need to add .svg file extension to my configuration.

At the moment in my project I have other extensions as (pdf, images)

I made the following changes

Added a new svg_file to the context
Added the file provider (In the end of configuration file)
Added the svg in allowed_extensions
Added the image/svg+xml in allowed_mime_types

Now, I can upload the svg file but the problem is that the user can upload other file extensions for example pdf etc..

How can avoid it? Or find a proper way for the form validation?

The Sonata documentations:

帮助了我，但不是表单验证。

我缺少什么？

我更改了以下文件：

#app/config/sonata_config.yml

sonata_media:
default_context: images_file
db_driver: doctrine_orm # or doctrine_mongodb, doctrine_phpcr
contexts:
    pdf_file:
        providers:
            - sonata.media.provider.file
        formats: ~
    images_file:
        providers:
            - sonata.media.provider.image
        formats:
            1x: { width: 870 , height: 412 , quality: 80 }
            2x: { width: 1740 , height: 824 , quality: 50 }
    svg_file:
        providers:
            - sonata.media.provider.file
        formats: ~
    cdn:
        server:
          path: /uploads/media # http://media.sonata-project.org/

    filesystem:
        local:
           directory:  %kernel.root_dir%/../web/uploads/media
           create:     false

    providers:
        file:
           service:    sonata.media.provider.file
           resizer:    false
           filesystem: sonata.media.filesystem.local
           cdn:        sonata.media.cdn.server
           generator:  sonata.media.generator.default
           thumbnail:  sonata.media.thumbnail.format
           allowed_extensions: ['pdf', 'txt', 'rtf', 'doc', 'docx', 'xls', 'xlsx', 'ppt', 'pttx', 'odt', 'odg', 'odp', 'ods', 'odc', 'odf', 'odb', 'csv', 'xml','svg']
           allowed_mime_types: ['application/pdf', 'application/x-pdf', 'application/rtf', 'text/html', 'text/rtf', 'text/plain', 'image/svg+xml']

表格档案：

use Sonata\AdminBundle\Admin\Admin;
class CustomAdmin extends Admin
{
/**
 * @param FormMapper $formMapper
 */
protected function configureFormFields(FormMapper $formMapper)
{
    $formMapper
        ->add(
            'NormalLogo',
            'sonata_type_model_list',
            array('required' => false),
            array(
                'link_parameters' => array('context' => 'images_file', 'provider' => 'sonata.media.provider.image'),
            )
        )
        ->add(
            'SvgLogo',
            'sonata_type_model_list',
            array('required' => false),
            array(
                'link_parameters' => array('context' => 'svg_file', 'provider' => 'sonata.media.provider.file'),
            )
        )
        ->add('overriddenBy', 'sonata_type_model',
            array(
                'empty_value' => 'Not overridden',
                'btn_add' => false,
                'btn_list' => false,
                'btn_delete' => false,
                'btn_catalogue' => false,
            )
        );
}
}

您只能为SVG文件创建自己的提供程序，您需要先为SVG提供程序定义服务

parameters:
    application_sonata_media.svg_class: Application\Sonata\MediaBundle\Provider\SVGProvider
services:
    sonata.media.provider.svg:
          class: %application_sonata_media.svg_class%
          tags:
              - { name: sonata.media.provider }
          arguments:
              - sonata.media.provider.svg
              - @sonata.media.filesystem.local
              - @sonata.media.cdn.server
              - @sonata.media.generator.default
              - @sonata.media.thumbnail.format
              - allowed_extensions: ['svg']
              - allowed_mime_types: ['image/svg+xml']

使用奏鸣曲你可以使用EASYEXTENDS BUNDLE生成扩展束，默认情况下它会在src/Application/Sonata/MediaBundle中生成扩展束，但你也可以指定其他目的地。现在在扩展媒体包中创建以上服务＆＃39; s { {1}}并在主services.yml中导入。如果您想添加更多mime类型或扩展程序，可以在上面的服务config.yml中定义

allowed_mime_types: ['image/svg+xml','application/pdf']

现在在扩展媒体包中创建您的提供者类imports: - { resource: @ApplicationSonataMediaBundle/Resources/config/services.yml }并使用奏鸣曲媒体扩展您的提供者类SVGProvider

FileProvider

在这里你可以覆盖基类函数并根据需要定义自己的功能，例如你想为文件输入添加一些验证，你可以自定义<?php namespace Application\Sonata\MediaBundle\Provider; use Sonata\MediaBundle\Provider\FileProvider as BaseFileProvider; use Gaufrette\Filesystem; use Sonata\AdminBundle\Form\FormMapper; use Sonata\AdminBundle\Validator\ErrorElement; use Sonata\MediaBundle\CDN\CDNInterface; use Sonata\MediaBundle\Generator\GeneratorInterface; use Sonata\MediaBundle\Metadata\MetadataBuilderInterface; use Sonata\MediaBundle\Model\MediaInterface; use Sonata\MediaBundle\Thumbnail\ThumbnailInterface; use Symfony\Component\HttpFoundation\File\File; use Symfony\Component\HttpFoundation\File\UploadedFile; use Symfony\Component\Validator\Constraints\NotBlank; use Symfony\Component\Validator\Constraints\NotNull; class SVGProvider extends BaseFileProvider { protected $allowedMimeTypes; protected $allowedExtensions; protected $metadata; public function __construct( $name, Filesystem $filesystem, CDNInterface $cdn, GeneratorInterface $pathGenerator, ThumbnailInterface $thumbnail, array $allowedExtensions = array(), array $allowedMimeTypes = array(), MetadataBuilderInterface $metadata = null ) { parent::__construct( $name, $filesystem, $cdn, $pathGenerator, $thumbnail ); $this->allowedExtensions = $allowedExtensions; $this->allowedMimeTypes = $allowedMimeTypes; $this->metadata = $metadata; } public function buildCreateForm( FormMapper $formMapper ) { $formMapper->add( 'binaryContent', 'file', array( 'label' => 'Upload SVG file only', 'constraints' => array( new NotBlank(), new NotNull(), ), ) ); } /** * {@inheritdoc} */ public function validate( ErrorElement $errorElement, MediaInterface $media ) { if ( ! $media->getBinaryContent() instanceof \SplFileInfo ) { return; } if ( $media->getBinaryContent() instanceof UploadedFile ) { $fileName = $media->getBinaryContent()->getClientOriginalName(); } elseif ( $media->getBinaryContent() instanceof File ) { $fileName = $media->getBinaryContent()->getFilename(); } else { throw new \RuntimeException( sprintf( 'Invalid binary content type: %s', get_class( $media->getBinaryContent() ) ) ); } if ( ! in_array( strtolower( pathinfo( $fileName, PATHINFO_EXTENSION ) ), $this->allowedExtensions ) ) { $errorElement ->with( 'binaryContent' ) ->addViolation( 'Invalid extensions' ) ->end(); } if ( ! in_array( $media->getBinaryContent()->getMimeType(), $this->allowedMimeTypes ) ) { $errorElement ->with( 'binaryContent' ) ->addViolation( 'Invalid mime type : ' . $media->getBinaryContent()->getMimeType() ) ->end(); } } }函数来改变文件输入字段的属性，你可以在其中定义它validate()方法

现在在您的管理员中如果您只想允许SVG上传，您可以定义自己的提供商，只允许SVG文件
