SonataMediaBundle:如何添加svg文件扩展名

[英]SonataMediaBundle: How to add svg file extension

我需要在配置中添加.svg文件扩展名。

在我的项目中,我有其他扩展名(pdf,图像)

我做了以下更改

  1. 上下文中添加了新的svg_file
  2. 添加了文件提供程序(在配置文件的末尾)
  3. allowed_extensions中添加了svg
  4. allowed_mime_types中添加了image / svg + xml

现在,我可以上传svg文件,但问题是用户可以上传其他文件扩展名 ,例如pdf等。

怎么能避免呢? 或者找到适合表单验证的方法?

索纳塔文件:

帮帮我,但不是表格验证。

我错过了什么?


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,您需要首先为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。现在在扩展媒体包的services.yml创建以上服务并在main config.yml导入config.yml 。如果你想添加更多mime类型或扩展,你可以在上面的服务中定义allowed_mime_types: ['image/svg+xml','application/pdf']

imports:
    - { resource: @ApplicationSonataMediaBundle/Resources/config/services.yml }

现在在扩展媒体包中创建您的提供者类作为SVGProvider并使用sonata媒体的FileProvider扩展您的提供者类

<?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();
        }
    }
}

在这里,您可以覆盖基类函数并根据需要定义自己的功能,例如,您想要为文件输入添加一些验证,您可以自定义validate()函数来更改文件输入字段的属性,您可以在buildCreateForm()方法中定义它

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程序,只允许SVG文件

protected function configureFormFields(FormMapper $formMapper)
{
    $formMapper
        ->add(
            'SvgLogo',
            'sonata_type_model_list',
            array('required' => false),
            array(
                'link_parameters' => array('context' => 'svg_file', 'provider' => 'sonata.media.provider.svg'),
            )
        )
}
