concat validation rules with form_validation

Hi.

Yes, like marksman has said, max_length[15] for email was an example.
Then, if it is normal behaviour, everything cleared up, OK.
Anyway, I will use js validation before validation in server with Form_validation, so if there are several errors, will show all.

Thank you very much for acclarations.

I use jQuery Form validation, but that also only shows one error per field.
I don't think it would make sence to show all requirements when a field fails
