</div>

Answer 1

You can validate a field which is not in the database.
e.g. In a register form you can validate “I accept user terms” field and don’t save this value on the database.

In your code you’re validating “accept” instead “agree”. In fact, you have two inputs with the same name ("data[Season][agree]"), it could be a problem.
