Just a thought, you could modify the file upload snippet to append user information, etc. to the file name, then a fairly simple snippet could read the directory, parse the filename, display the info, and give a link to the file (the link wouldn’t have to show the fill filename).
I’m updating the old FileCabinet snippet which is a file-to-document creation snippet originally designed for the MODx site repository; it should be in the extras in a day or two.
No real advantage, the file-to-doc setup just uses the site_content table as its own meta data store for the files. Might as well use documents as have a custom table with fields for meta data that for the most part (name, description, date, creator) the site_content table already has. If you don’t want that kind of meta data in the database, then a simple upload and listing snippet would do fine.
I’m glad you got it working.
