dynamic form validation

Hi guys,

I was just wondering what is the best way to have a dynamic form validation. Let's say you don't know what the _POST values are, well they could be anything, but you set a rule in the database as to what validation rule it needs.

Is it possible to generate a dynamic form validation on the fly and then repopulate the view if said input fails using set_value().

And what would be best to store the validation rules. Maybe a json array?

Regards,

Iamthwee.
