Validation should be done BOTH on the client and on the server. This even includes validation that has already been done on the client, due to the risk of spoofing.

The only reason validation is first done on the client is to reduce the number of round trips between the client and the server.

RE: User Input Data Validation

User input validation is Client side only because there is no need to Validate Serverside.
If get the values from DB then you need to validate Serverside
