I have code that runs after user submits form, to rewrite fields before sending them to the database. I could probably just check during this 'post process phase' to make sure everything rewrites effectively before attempting to write to the database, but I saw the callback feature and am trying to see if that would allow me to use more of the CI functionality.
I have two problems: I have one large controller divided into several libraries. The callbacks all have to go into the controller from what I can tell, this makes my chosen organization not work very well.
Second problem, is when I return a value from the callback besides TRUE (rewritten value), it does not change the form data it appears.
