Custom validation error messages per rule

the line is related to the method. If there is no method the line is fat for the language file.

You can go without the line but then the easiest way is to put the string in the set_message method. This is less flexible as you hard code the string then. You can create another language file to put your custom lines in en load it when you need to use the set_message method.

I wonder why you find it so strange that you need a function and a language line because that is how the CI default rules work as well.
