If, for example, a user is making a contribution, is there a way to easily apply preg_match to fields like postal code and phone number, and return error messages? Contributions will only be from US addresses, so postal codes will be limited to ZIP and ZIP+4, and phone numbers will be limited to 10 digits plus various separators.

Improper ZIP codes can lead to a fair amount of failed transaction requests. I'd rather catch these problems prior to sending it to the credit card processor.

If you're ok about having the validation be "server-side" (i.e. not Javascript client side error trapping) - then you might be able to use the validation hook described here:
