创建一个临时文件夹以保持文件的结构，并通过压缩文件夹使其下载 [英] Create a temporary folder to keep the files in structure and make it downloadable by compressing the folder

问题描述

在我的项目中，我有一些与服务器上的项目有关的文件，如下所示：

  Item-1 => file1.txt，file2.pdf和file3.doc 
 Item-2 => file4.pdf，file5.ppt 
 Item-3 => file6.txt，file7.docx和file8.ppt 
 .... 
  

我可以通过 $ this-> getAllItems（）获取以上项目，然后循环遍历每个项目。

我是试图以结构化的方式压缩所有这些文件。所以，用户可以理解文件属于哪些项目。

我想要做的是将与他们尊重的项目相关的文件保存在文件夹中，并将其包装起来一个主文件夹（这应该发生在临时路径中）然后压缩它，让用户下载压缩文件夹。所以，这些文件的结构方式如下所示：

  main 
项目1 
 - > file1.txt 
  - > file2.pdf 
  - > file3.doc 
项目-2 
  - > file4.pdf 
  - > file5.ppt 
项目-3 
  - > file6.txt 
  - > file7.docx 
  - > file8.ppt 
  

在这里搜索时，我得到了一个链接，它将压缩临时路径中的文件（而不是文件夹），并使压缩文件夹可供下载。

PS：压缩应该由用户每次下载请求发生。

解决方案

我不知道这是否正确..但是这样做有效。

我修改了for循环部分代码， a href =https://stackoverflow.com/a/13930314/1577396>链接。

 ＃循环遍历每个文件
 foreach（$ files as $ file）{
 
＃下载文件
 $ download_file = file_get_contents（$ file）; 
 
＃创建一个空文件夹
 $ zip-> addEmptyDir（$ itemName）; 
 
＃添加到以上创建的新文件夹
 $ zip-> addFromString（$ itemName。'/'。basename（$ file），$ download_file）; 
 
} 
  

在上面的代码中， $ itemName 是在我的帖子中已经提到的 $ this-> getAllItems（）中循环动态获取的项目名称。 / p>

请让我知道这是否正确。

In my project, I have some files related to items on Server as shown below:

Item-1  => file1.txt, file2.pdf and file3.doc
Item-2  => file4.pdf, file5.ppt
Item-3  => file6.txt, file7.docx and file8.ppt
....

I can get the above items by $this->getAllItems() and then loop through each item.

I am trying to compress all these files in a structured way. So, that the user can understand files belong to which items.

What I am trying to do is keep the files related to their respected items in a folder and wrap them in a "main" folder (this should happen in a temporary path) then Compress it and let the user download the compress folder. So, that the files will be in structured way as shown below:

main
   Item-1
      --> file1.txt
      --> file2.pdf
      --> file3.doc
   Item-2
      --> file4.pdf
      --> file5.ppt
   Item-3  
      --> file6.txt
      --> file7.docx
      --> file8.ppt

While searching here, I got a link which does compress the files (but not folders) in a temporary path and make the compressed folder available to download.

PS: The compressing should happen for every download request by users.

解决方案

I am not sure whether this is correct or not.. but this worked.

I modified the for loop part of the code which is available on this link.

# loop through each file
foreach($files as $file){

    # download file
    $download_file = file_get_contents($file);

    # Create a empty folder
    $zip->addEmptyDir($itemName);

    #add to the above created new folder in zip
    $zip->addFromString($itemName . '/' . basename($file), $download_file);

}

In the above code, $itemName is the item name which is fetched dynamically while looping in $this->getAllItems() as I had already mentioned in my post.

Please let me know if this is correct or not.
