I have make a custom validation for date formate check but when I use in in validation rule as callback function it show the error that the function is not define. May be it will called with module. Please help me to find the solution.

When using form validation with MX you will need to extend the CI_Form_validation class as shown below,

/** application/libraries/MY_Form_validation **/ 
class MY_Form_validation extends CI_Form_validation 
{
    public $CI;
}

before assigning the current controller as the $CI variable to the form_validation library. This will allow your callback methods to function properly.

class Xyz extends MX_Controller 
{
    function __construct()
    {
        parent::__construct();

        $this->load->library('form_validation');
        $this->form_validation->CI =& $this;
    }
}

This will remove HMVC related callback problem without any changes to your code. source: https://stackoverflow.com/a/38357164
