Basically, I don't know how else to handle inserting and updating random
number of authors. Each book in the db may have up to 5 authors. I
imagine there is a simpler way to do it; I just don't have the knowledge
or experience or the time to learn another way. I'd be happy to have you
look at the code and hear some feedback. It's probably a miracle that
the site is working... ;-)
Oh, it's www.ptahhotep.com - my daughter's egyptology site; I just
migrated from pure (almost) html to php/mysql/css and am just doing the
finishing touches now - the edit page.
