CMS/Intranet file upload system

Question

In my attempts to write a CMS or intranet system, I need the ability to upload files to a "workspace", which is permissions based.

Now I can sort the permissions out, however, I am struggling a bit with the file upload itself.

Basically, such as a VLE, let's say I am a manager. I want to upload a file for those in my department to see. How do I do this?

Now, I could easily upload the files to the server via FTP, however, this isn't practical from a remote location, hence the need to upload.

The file should be stored in the /upload/ folder, and have a random string, such as vBulletin does with it's user's images.

Thanks

The actual file upload is relatively simple. There are tons of tutorials like this one to help. You will need to use a database to manage the permissions though.

For instance, when you upload a file, note its name and location along with an owner or a set of permissions in the database. When someone requests a file you can always check the database for the permissions.

For example

file =(id, filename, location, ...)
user = (id, username, password, ...)
filegroup = (id, groupname, ...)
file_filegroup(fileid, groupid, ...)
uer_groups = (groupid, userid, ....)

this structure would allow you to store files as groups such as a department group and allow a user to have access to one or more groups.
