Is it possible to upload file without known extension?

CyberGene

enricodx there’s a list of extensions you can provide that won’t get changed. Add rar to it.

enricodx

CyberGene can you help me with the right expression to use? I’m not a programmer...

Also there is a way to accept file without extension at all?

CyberGene

enricodx that's not an expression. There's a separate setting called "User-provided file extensions" where you provide a comma separated list of file extensions which you would like to preserve as is. If it's empty put "rar" there. If not, just add a comma (no spaces) and then add "rar". (no quotes, I put them for clarity)

enricodx

CyberGene Cool! It works, thanks a lot!!

And what about files without extension?

CyberGene

enricodx Cool! It works, thanks a lot!!

And what about files without extension?

Glad it worked for you. Regarding files without extension, I believe the MIME type of the content will be detected and then an extension will be chosen that matches the content. Not sure though. @luceos should confirm.

clarkwinkelmann

enricodx And what about files without extension?

I don't think that's supported. Is there any reason the file should be kept without extension on the hosting?

If the downloaded file name is important a feature we could add is the ability to provide a download filename in the bbcode, this is a lot easier than adapting all the storage logic that renames file for security.

clarkwinkelmann I’m building a forum for storing modded levels of a game, which have no extension. For now each user have to zip the file, it would be nice to be able to upload the file directly 🤔

clarkwinkelmann

enricodx I think you can upload files without extensions just fine, they will probably be renamed with a .bin extension on the server.

I don't remember if we have client-side MIME suggestions in this extension. If you can't select the file in the browser file selector, maybe it has something to do with that part. But if I remember correctly all validation is server-side. You can use the MIME inspector button to check what comes out for one of your extension-less file.

enricodx

clarkwinkelmann I made a test with the tag ^application\/.* in the settings, and now any file get uploaded and renamed .bin if without extension.
But how can I prevent .exe files from being loaded as well?

Wlork

I use this extension and I upload with IMGUR to avoid overloading the server. It works well.

The images are automatically resized on forum but when we want to see the image in normal size, nothing happens when we click on it.... Is this normal?

clarkwinkelmann

Wlork I believe image resizing is applied on the upload before being saved on the server. It's not a thumbnail, it's the actual file that ends up being attached to the post. I don't think this extension can generate lower size thumbnails of full images.

Hi, and thank you for taking your time to write this extension.

There seems to be a few bugs with this extension and I believe the issue's maybe down to PHP 8+ (I cannot default back to PHP 7.4+ unfortunately).

The issue seems to be with 'Configure your mime type, upload adapter mapping'. If add another 'local' option after the default image template, the settings will not save and my options will not be there after I refresh. Which means I cannot upload any files which are not images.

If I add another option in the 'Configure your mine type' field, the save button stays 'greyed out' and I am unable to save the new settings. I have to remove any previous settings and readd them before I am able to save.

Also, asking your users to use regex for settings in not user-friendly. I'm sure if you have years of experience in programming or regex, then this would be fine. Could you not change the options/settings to use extension only and match this up with the mime type?

Sorry to be a pain in the ass, and again, thank you for your extension.

Debugging gives the following error:

422 Unprocessable Entity: The 422 Unprocessable entity indicates that the action could not be processed properly due to invalid data provided.

Hello,

How do I increase the maximum size of post and image?

Lumeinshin

Wlork
Its been a while since I had to, but you can change the file size in the extensions config page, just search upload in the search bar on your admin panel.
You may also have to change the max upload size in your nginx.conf server side as well, I had to for my forum, as well as in the php.ini found in your server application (docker usually)
You can change the raw size of the image via custom css, something like the max-height one might be a good one to change

I hope this helps!

clarkwinkelmann

bachmx check Flarum log file and browser development console for error message, enable debug mode to get more verbose errors if needed. See https://docs.flarum.org/troubleshoot

Hi!
Please Help!
FOF Upload always rename my files from RUS to ENG:
МебельЖурнальный столКруглый_2.rfa --> mebel-zurnalnyi-stol-kruglyi-2.rfa

Its critical for me because after it i cant use that files, after download i need to rename it from ENG to RUS(
Any solutions?

clarkwinkelmann

georgenovak97 it does not seem to be customizable at the moment.

The filename is always converted to ASCII only, probably to maximize compatibility with all disk adapters https://github.com/FriendsOfFlarum/upload/blob/b582f96b5c0354d6433b1ed4f9886f41166b4e34/src/Repositories/FileRepository.php#L243

If you decide to fork/edit the extension make sure you prevent file system transversal attacks when filtering your alternate filename (I think restricting just ., / and \ should be enough but I'm not 100% sure).
