Thread:Project:Support desk/Allow zip uloads for trusted users?

Versions: MediaWiki - 1.22.1, PHP - 5.4.27, MySQL - 5.5.37

Wiki: http://www.vgmpf.com

I'd like to allow zip file uploads for trusted users only. I understand that allowing zip uploads in a security risk, but I have several users who have been working on my Wiki for years and have been added to a custom trusted user group, and they are competent enough not to upload malicious files. Does anyone know if Media Wiki is capable of this, and how I would go about doing it?

So far, I've looked into the $wgFileBlacklist array and the $wgVerifyMimeType flag, but I can only seem to get zip uploading for everyone, not just a particular user group.

Thanks in advance!
