            $this->addError('code_meli', 'کد ملی باید 10 رقم باشد');
        }

        for ($i = 0; $i < 10; $i++) {
            if (preg_match('/^' . $i . '{10}$/', $code_melli)) {
                $this->addError('code_meli', 'کد ملی صحیح وارد نشده است');

        for ($i = 0, $sum = 0; $i < 9; $i++) {
            $sum += ((10 - $i) * intval(substr($code_melli, $i, 1)));
        }

        $ret = $sum % 11;
        $parity = intval(substr($code_melli, 9, 1));
        if (($ret < 2 && $ret == $parity) || ($ret >= 2 && $ret == 11 - $parity)) {
            return true;
        }
