Validation of Data / AJAX

Greetings,

Uhm ... That's a good question. I'm not sure how you pass in the extra parameter on functions like exact_length. As for error messages, I believe you would be looking for:

Code:

$this->form_validation->set_message('rule', 'Error Message');

See the section on "Setting Error Messages".
