Custom validation error messages per rule

[eluser]xwero[/eluser]
The rule aliases go in the extended Validation class. This makes it possible to use them where ever you want.

That is why i added in a later response the possibility to do it as a callback of one time custom messages.

I the form only contains one required rule you can use the validation->set_message method because then you don't have to look at what the other required rules output.

The Validation class, and CI in general, gives you a lot of freedom and you should search first for solutions within the reach of CI before you start overwriting methods. It's a mistake i made, and still make now and then, too.
