使用OneUpUploaderBundle

简介

我将Symfony v4.1.*与OneUpUploaderBundle一起使用。 我需要为每个上传的文件设置唯一的名称-可以。

我有tree structure，其中包含上传的文件。 为了管理树中的文件，我有多个属性。 其中一些是：

  1. itemName （音译文件名+计数器+ unique_sting）
  2. itemOriginalName （音译文件名+计数器）
  3. itemExtension （文件扩展名-例如.txt或.a（如果是目录）
  4. itemSortValue （文件扩展名+音译文件名+计数器+ unique_sting）

ItemSortValue确保树枝（字段）按字母顺序排序。

问题

  

我还需要将有关上传文件的信息保留在数据库中。   为此，我需要在complete file name事件的UploadNamer中获得UploadListener管理的每个onPostUpload。

path/to/file/my_file_name(counter)_{time}_{uniqueString}.extension

我需要将相同的唯一文件名保存到数据库。 然而，我面临的问题是-我不知道，也找不到如何将信息从UploadNamer传递到uploadListener。

我尝试使用$this->originalName，但没有得到积极的结果。

问题

如何使用UploadNamer将UploadListener中的值从Symfony v4.1传递到OneUpUploaderBundle中的{em>（onPostUpload事件）？

代码：

  

自定义名称

public function name(FileInterface $file)
{
    $upload_file_path = $this->ultraHelpers->getUploadableFilePath();

    $unique_string = $this->ultraHelpers->getUniqueString(true);

    $file_name = $file->getClientOriginalName();
    $file_info = $this->ultraHelpers->filterFileInfoFromFilename($file_name);

    return sprintf('%s/%s_%s.%s',
        $upload_file_path,
        $this->ultraText->transliterateText($file_info['name']),
        $unique_string,
        $file_info['extension']
    );
}
  

UploadNamer示例输出

dir1/dir2/dir3/my_file_name_1539617029_23bf16f962c658103f10ece7d3ba7a88.txt

that corresponds to
path/to/file/my_file_name(counter)_{time}_{uniqueString}.extension
  

我的UploadListener 

<?php

    protected $ultraText;

    /**

    protected $ultraFileTree;

    protected $originalName;

    public function __construct(EntityManagerInterface $entityManager, SessionInterface $session, ContainerInterface $container, UltraHelpers $ultraHelpers, UltraText $ultraText, UltraFileTree $ultraFileTree)
    {
        $this->entityManager = $entityManager;
        $this->session = $session;
        $this->container = $container;
        $this->ultraHelpers = $ultraHelpers;
        $this->ultraText = $ultraText;

        $this->originalName = [];
    }

    public function onUpload(PreUploadEvent $event)
    {
        $file = $event->getFile();

        $file_info = $this->ultraHelpers->filterFileInfoFromPath($file->getClientOriginalName());
        $this->originalName = $this->ultraText->transliterateText($file_info['name']);

        $response = $event->getResponse();
        $message = [
            'error' => 'none'
        ];
        $response->addToOffset($message, array('files'));
    }

    public function onPostUpload(PostUploadEvent $event)
    {

        $repo_file_tree = $this->entityManager->getRepository('App:FileTree');
        $repo_project = $this->entityManager->getRepository('App:Project');
        $repo_whereabouts = $this->entityManager->getRepository('App:Whereabouts');

        $whereabouts = $this->session->get('whereabouts');
        $my_whereabouts = $repo_whereabouts->getWhereabouts($whereabouts);

        // get project object
        $project_obj = $repo_project->findOneBy(array('id' => $my_whereabouts['project_id']));
        // get current directory object
        $node_selected_obj = $repo_file_tree->findOneBy(array('id' => $my_whereabouts['node_selected_id']));

        $file = $event->getFile();
        $file_size = $file->getSize();

        $current_file_name_parts = $this->ultraHelpers->getFileNameParts($this->originalName);
        $postfix_txt = $this->ultraHelpers->getFileNamePostfixTxt($current_file_name_parts['name'], $my_whereabouts['node_selected_id']);

        $file_tree = new FileTree();
        $file_tree->setItemOriginalName($current_file_name_parts['name'] . $postfix_txt);
        $file_tree->setItemName($current_file_name_parts['name'] . $postfix_txt);
        $file_tree->setItemExtension('.'. $current_file_name_parts['extension']);
        $file_tree->setItemSortValue('.'. $current_file_name_parts['extension'] .'.'. $current_file_name_parts['name'] . $postfix_txt);
        $file_tree->setItemSize($file_size);
        $file_tree->setUpdatedAt(new DateTime($now_date_time));
        $file_tree->setIsFile(true);
        $file_tree->setParent($node_selected_obj);
        $file_tree->setProject($project_obj);

        $this->entityManager->persist($file_tree);
        $this->entityManager->flush();
        $this->entityManager->clear();

        // pārkārto FileTree koka zaru ievērojot jaunpievienoto failu
        $file_tree_branch_node_id = $repo_file_tree->getOneFileTreeNode($my_whereabouts['node_selected_id']);
        $this->ultraFileTree->reorderFileTreeBranch($file_tree_branch_node_id);

        $event->getResponse();

一个人可以在eventListener中用wrap_content从命名者那里获取文件名。

随后的代码块中出现了偷偷摸摸的错误，因此使我相信文件名存在问题...
