2Yes - I always do both (when I do it at all). Server-side is 100% the most important though. – Reinstate Monica Cellio Nov 21 '16 at 11:44

1yes it's always better approach to put validation both side. So that not even a single % chance will be there for errors – Alive to die - Anant Nov 21 '16 at 11:44

to put it simple: *server*-side validation is neccessary, *client*-side validation is user-convenience. – Franz Gleichmann Nov 21 '16 at 11:48

Yes. You should use both.
Client side - most validations are for the user inputs (e.g. invalid characters, regular expressions, etc.)
Server side - most validations are related to business logic (e.g. user authority, use privileges, etc.)

Server-side validation is enough to have a successful and secure form validation. For better user experience, however, you might consider using client-side validation.
