Why use strings when doing rules for Form Validation instead of flags

I suppose you pay a tiny bit of processing overhead splitting the strings. However, the strings aren't really that large. If this were something iterative/recursive, I'd be concerned I suppose. I'd probably be looking for performance tweaks in other areas first though if it were me (database, etc.)

You can always extend the Form_validation class to pass in rules to your liking.

On a final note, this post may (or may not) get more mileage under the Ignited Code forum.
