I think the problem is ELSE section on last of the code snippet. so you have write something like this. Short definition. $ this- > form_ validation- > set_ message( ). Only work when the validation rules may failed. So i assume that. I writing a member registration form script that and I use that rule to validate the email address as well as the username. $ this- > form_ validation- > set_ message( ' rule', ' Error Message' ) ;. The above code won' t work for what I am. So this means CI checks if you have not set rule message to the field then check if there is a line that corresponds to the fired.
