Okay, that is what I thought. Last question and then I think I can point you in the right direction tomorrow -- as it is getting late for me. Why did you pick that particular hook? It does not make sense for the explanation you have just given, unless when editing a post you are trying to save information to the database from your page query parameter.

What am I missing? :)

You're likely not missing anything. :) I'm open to being completely wrong about the hook(s) I chose. If you recommend something different, I'm all ears.

I know I need to save this somehow, but I'm not sure where. I've already set up validfields for the new field. I just need to properly save it now without throwing database errors for the special characters.
