Custom validation error messages per rule

[eluser]xwero[/eluser]
You don't have to overwrite the rules to do what i propose. You only need to change the run method. Where the parameters are fetched you need to check if a custom message is added or not. If a custom message is added you need to check if the line exists and if it does display it.

I would advise against setting the custom message as second parameter because then you have to do things like

Code:

$rules['field4'] = 'required[,custom_msg]';
$rules['field4'] = 'required[param1,custom_msg,param2]';

As far as updating CI is concerned if you put your code in the MY_Validation.php file you can wait as long as you want to use your solution.
