MY Validation

Category:Libraries::Extended

Instead of using callbacks to add rules you can add rules by extending the validation library.

All additions are welcome

[code] <?php class MY_Validation extends CI_Validation {

var $_display_fieldname = array();

function MY_Validation()

    parent::CI_Validation();
}

* use with required rule
