Multiple file uploads

I have been looking for a way for a user to select multiple files to upload. I was hoping to use a normal file upload input field and allow the selection of multiple files, but after searching the internet it seems this isn’t possible. All the alternatives I found include java applets or AJAX uploading with photo resizing and all that.
The files to be uploaded are all small text files that are being imported into a database and therefore don’t need resizing and i would love to keep it simple without having to rely on javascript.
Up to 50 files may be selected at one time so having separate file input fields isn’t really an option.

How can I go about this?
