The Situation is like this:
I want to give the user the possibility to upload an audio-file OR to just paste a Link to an audio-file that is hosted somewhere on the internet.
So all in all it is a question of how to have a Custom Field Value manipulated before beeing stored into the database.
My Idea was, to add a snippet of Code somewhere to parse the Uploaded Audio-File Element from the Upload-Option to store only the Element->URL Value so that i can store that into the second field (Link-Option).
But how to do that kind of thing, or does someone have another good idea for that?
The Point is, that I need the Website User to have it as simple as possible.
So how to have two options (Fileupload and Link-URL) but only one stored Data Field, that consists of only a Link-URL.
