Can I show a file upload field on an update form if no file already exists?

Ah, I see. So, if I pass a new value to that field, it will simply replace what's in the db. And just display a new upload field via a link or button with an onClick and some CSS. The "delete" part is not as clear. I think I can wrap my head around using js to pass a value to a hidden form field, but I don't know enough php/SQL to know how to empty from the db. Any pointers?
