Either ajax based or the traditional full form post.  Validation such
as credit card numbers, phone numbers, states, zip codes, email
addresses, etc.

> My office generally designs forms so that fields either don't need validation (a list of state abbreviations instead of a text box; a Javascript date picker) or are validated by Javascript (checking email address formatting or credit card number formatting). That way the user gets immediate feedback and doesn't have to send the form to the server for validation. For things like full text search fields, we just throw the query at the full text search server and let it figure it out.

Javascript validation is good, but won't validate submissions through
mechanized interfaces (which includes spammers).  Getting full browser
compatibility is something you don't have to worry about also when you
have the server side handling the form validation.
