How to upload files without changing original filenames

[homma]

How can I upload files without changing the original filenames?

I use processwire in English and Japanese.
When I upload a file, the filename is sanitized and changed to an alphanumeric name.

I need some files to be uploaded with original filenames with Japanese characters (2-byte characters).

Is there a good way to do this?

Thanks in advance,

Yu

Hi,

ProcessWire doesn't support non alpha numberic file name. I have made a feature request in within and waiting Ryan implement it but seems that he has no plan to do it in the near future.

Hello Gideon,

Thanks for your message. It's a pity that non-alphanumeric filenames are not supported.
I need to integrate another file management system just because of this. Wordpress has a option to keep the original filenames, but I really want to use Processwire for my project.

@ryan, do you have any plan to implement this feature, in the core or plugin (or anything)?

Have you tried serving file with PHP instead of just linking it? You can change the filename using HTTP headers this way

may i ask WHY? if we know the reason we may can suggest some other way of achieving almost the same need

Hello all,

Thank you for your advice!

@bernhard, the reason is that I need to let users download files with Japanese filenames.
So, as @abdus suggested, if I can change the filename to, for example the value in 'Description' field of the file, it is OK.
I don't need to keep original filenames on the webserver.

Would you advice me how I can do this?

Thank you!

you could just take the code example from abdus, activate url segments for your site and do something like this:

// list your files to download
foreach($page->files as $i=>$file) {
  echo '<a href="' . $page->url . $i . '" target="_blank">Download File ' . ($i+1) . '</a>';
}

and in your template file:

if($num = $input->urlSegment1) {
  $file = $page->files->eq($num);
  // continue with abdus script
}

maybe not without bugs but should show one possible solution

Although browser support is not perfect, you can also use anchor links with download attribute to force download with a certain filename.

<a href="link/to/my/file/with/a/name/i/dont/like.jpg" download="MyFile.jpg">Download</a>

Thank you @bernhard and @abdus !
The download attribute is very simple and easy, but I'm not sure I can ignore IE.

I'll work on this and come back with (hopefully good) results

Hi @homma,

Someone posted a solution in github. I tested it and it works fine. The downside is that you have to modify the core of ProcessWire which mean you have to do it again every time you upgrade your core.

Hello @Gideon So and @adrian,

Thank you for sharing the github link. I quickly read the threads and noticed some people have the same concern.
I wanted to test the modified core file, but the Dropbox link seems to expire now. Do you happen to have a copy?

I currently try the solution bernhard and abdus suggested, but it turns out simply use Content-Disposition doesn't work on some browsers.
I'm looking at this code now, which partially solve my problem.

Hi @homma,

Yes. I do keep a copy here. It is for 3.0.42. I am not sure whether it works with the latest version.

Thank you @Gideon So!

I tested it and it worked quite well. I really hope this feature is realised in the core...
