it would be good to know what your input variable $str contains... — dom, Feb 12 '18 at 06:43

use your own validation methods some thing like this

<?php

class Form extends CI_Controller {

        public function index()
        {
                $this->load->helper(array('form', 'url'));

                $this->load->library('form_validation');

                $this->form_validation->set_rules('password', 'Password', 'required|callback_password_check');


                if ($this->form_validation->run() == FALSE)
                {
                        $this->load->view('myform');
                }
                else
                {
                        $this->load->view('formsuccess');
                }
        }

        public function password_check($str)
        {
                if (preg_match('(?=.*[a-z])(?=.*[A-Z]).*', $str))
                {
                    return TRUE;
                }
                else
                {
                    $this->form_validation->set_message('password_check' , 'Please provide a stronger password');
                    return FALSE;
                }
        }

}
