Form validation method - how to

[landed]

I have a form and require to validate it. It seems this has been documented very little and there are some 1x solutions here which I cant fully grasp. As it stands I see that I need to attach a model to each field I want validated and have a validation in those models. I think a demo would be most welcome for us all on this important matter. Thanks

If you use a model to populate the form then you could add validations to that model and validate against it after setting data to the model. If you don't use a model to populate the form then you still need to use a model with validations, set the data to that model and validate.
