安装

composer req 2lenet/attachment-bundle

将以下内容添加到您的 config/routes.yaml 文件中（目前没有 flex 食谱）。

lle_attachment:
    resource: "@LleAttachmentBundle/Resources/config/routing/routes.yaml"

在模板中嵌入控制器

{{ render(controller('lle.attachment', {'item': item})) }}

或者使用字段，如果您只想显示一组附件

{{ render(controller('lle.attachment', {'item': item, options: {'field': 'pdf'}})) }}

这样您就可以使用 "lle.attachment" 动作与 EasyAdminPlusBundle 一起使用

show:
    title: title.examen.show
    fields:
        - { type: 'tab', id: 'documents', label: 'tab.documents', action: 'lle.attachment'}

或者使用字段，如果您只想显示一组附件

show:
    title: title.examen.show
    fields:
        - { type: 'tab', id: 'documents', label: 'tab.documents', action: 'lle.attachment', options: {'field': 'pdf'}}

信息：lle.attachment 是 lle.attachment.show.action 的别名

易于使用

渲染上传小部件

{{ render_attachment(entity) }}

渲染下载列表（ul）

{{ list_attachment(entity) }}

您可以在同一模板中使用多个附件

{{ render_attachment(item) }}

{%  for examen in item.examens  %}
    <h3>{{ examen }}</h3>
    {{ render_attachment(examen) }}
{%  endfor %}

配置

使用默认值

framework:
    translator:
        fallbacks: ['fr']
  
lle_attachment:
    directory: data/attachment #directory of files is registred
    show_list: false #show or not show the list of files (table) with uploader widget
    need_confirm_remove: true #modal for confirm delete or no

感谢使用

预先加载实体列表

如果您使用 20 次调用 {{ list_attachment(entity) }} 列出 20 个实体，您希望只进行 1 次请求，而不是 20 次

调用

<?php
$this->attachmentManager->load(MyEntityClass::class, $ids);

以下是与 EasyAdmin 的示例

<?php

namespace App\EventListener;

use App\Entity\Rapport;
use Lle\AttachmentBundle\Service\AttachmentManager;
use Symfony\Component\EventDispatcher\EventSubscriberInterface;
use EasyCorp\Bundle\EasyAdminBundle\Event\EasyAdminEvents;
use Symfony\Component\EventDispatcher\GenericEvent;

class RapportSubscriber implements EventSubscriberInterface
{
    private $attachmentManager;

    public function __construct(AttachmentManager $attachmentManager)
    {
        $this->attachmentManager = $attachmentManager;
    }


    public static function getSubscribedEvents()
    {
        return [
            EasyAdminEvents::POST_LIST => 'onPostList',
        ];
    }


    public function onPostList(GenericEvent $event)
    {
        if($event->getArgument('entity')['class'] === Rapport::class){
            $ids = [];
            foreach($event->getSubject()->getCurrentPageResults() as $item){
                $ids[] = $item->getId();
            }
            $this->attachmentManager->load(Rapport::class, $ids);
        }
    }



}

在表单中添加上传的文件

• 在实体中添加 UploadedFileAttachmentInterface 和 UploadedFileAttachmentTrait

use Lle\AttachmentBundle\UploadedFileAttachmentInterface;
use Lle\AttachmentBundle\UploadedFileAttachmentTrait;

• 在您的实体表单中添加

$builder->add('uploadedFilesAttachment', FileType::class, ['multiple'=> true]);
// or (and) $builder->add('uploadedFileAttachment', FileType::class, ['multiple'=> false]);
$builder->add('uploadedFilesAttachmentField'); //optional (default is null)

• 现在您需要在持久化后调用 addFileByEntity（实体标识必须创建）

$this->attachmentManager->addFileByEntity($entity);

• 这里是一个简单的 EasyAdmin 示例

<?php

namespace App\EventListener;


use Doctrine\ORM\EntityManagerInterface;
use EasyCorp\Bundle\EasyAdminBundle\Event\EasyAdminEvents;
use Lle\AttachmentBundle\Service\AttachmentManager;
use Lle\AttachmentBundle\UploadedFileAttachmentInterface;
use Symfony\Component\EventDispatcher\EventSubscriberInterface;
use Symfony\Component\EventDispatcher\GenericEvent;

class AttachmentSubscriber implements EventSubscriberInterface
{

    private $attachmentManager;

    public function __construct(AttachmentManager $attachmentManager){
        $this->attachmentManager = $attachmentManager;
    }

    public function addFile(GenericEvent $event){
        if($event->getSubject() instanceof UploadedFileAttachmentInterface){
            $this->attachmentManager->addFileByEntity($event->getSubject());
        }
    }


    public static function getSubscribedEvents()
    {
        return [
            EasyAdminEvents::POST_PERSIST => 'addFile',
            EasyAdminEvents::POST_UPDATE => 'addFile'
        ];
    }
}

• 如果您想，可以在实体中定义默认字段

public function getUploadedFilesAtachmentField(): ?string{
    return 'uploaded';
}

• 对于验证，请使用 Symfony 验证器注解或表单中的验证器（建议：如果您使用验证器注解，请创建自己的 Trait）
