File upload via form manager /custom php?

[Catalyst-X]

Is there anyway to upload a file using the form manager or a custom php routine?
I am wanting a select group of authenticaqted users to be able to upload a pdf file.

Thanks

I would reccomend that you write a form that allows users to upload pdf's. Drop that form on a page, and add a security group to that page so that only the select users can access the form.
