Create Zip Archive from files in File set

Permalink
Hello folks,

I have a problem creating ZipArchive from files in File set. My goals is making a zip or folder that can be downloaded from link (same as with getDownloadURL()). What I have are files from set but then I don't know how to procced. At this point I really don't care if it is a regular folder or zip archive as long as files are in there and it can ve downloaded. If anyone can provide a code example or point me where to find the answear it will be awesome.

So far no solution I have found worked, like I wanted it to work.

Thanks for all of your help!

Are you trying to create a custom block which would let you select a File Set and then display a "Download Archive" link which would download a zip of the Files in the File Set?

If not, what exactly are you trying to build?

Here's a project that creates a zip file and produces a download link for it:
https://github.com/gondwanasoft/simple-backup...

However, it doesn't know anything about file sets; nor does it produce a secure download link.

First of all I figure it out, I just needed to switch folder where I wanted ZIP file to be created and now the code works.
But yeah my goal was something like that (Download Archive). I would link you the website but it's not in english so it wouldn't be of much use. The thing I wanted is on page there are files from File set listed in table and at the bottom I wanted to have a button/link which triggers some kind of zip+download event of the files displayed, so something similar to what download archive I guess. So nevertheless I fixed my bug could you show me your solution for how can I make Downloadable arhive of file set?

I'm posting my code below. I know it's not the best so I'm open to critics :) I want to make new folder to store zip in seperate folder but so far I'm still have permission trubles.
<?php 
         $dirName = "application/files/thumbnails/file_manager_detail/" . $c->getCollectionName();
         if (!file_exists($dirName)) {
            mkdir($dirName, 0777);
         }
         $zip = new ZipArchive;
         $fileName = "application/files/thumbnails/file_manager_detail/" . $c->getCollectionName() . $c->getCollectionDateAdded() . ".zip";
         $res = $zip->open($fileName, ZipArchive::CREATE);
         foreach($files as $f) {
            $zip->addFromString($f->getFilename(), $f->getFileContents());
         } 
         $zip->close();
         $link = View::url("") . $fileName;
         ?>
         <td><a class="download-all" href="<?php echo $link; ?>"><?php echo t('Prenesi vse'); ?></a></td>
