I can't show validation error message when direct page

Question

I have this function for login checker, when $email and $password wrong I want add redirect to another page, like login on a facebook page, when $email and $password incorect they direct to different page but still login page(but not the same page) and sent the message it was incorect $email or $password to the page

function basisdata_cek($password){
    $email = $this->input->post('email');
    $result = $this->login->login($email,$password);
    if($result){
        $sess_array = array();
        foreach($result as $row){
            $sess_array = $arrayName = array('kode_daftar'=>$row->kode_daftar, 'email'=>$row->email, 'password'=>$row->password);
            $this->session->set_userdata('logged_in',$sess_array);
        }
        return true;
    }else{
        $this->form_validation->set_message('basisdata_cek','invalid email or password');
        return false;
    }
}

But the problem is when I add redirect page like this

}else{
    redirect(base_url('index.php/login'),'refresh');
    $this->form_validation->set_message('basisdata_cek','invalid email or password');
    return false;
}

It's still direct page when it's incorrect email & password but the message of form_validation won't show up.

The information is lost on the redirect because the whole process starts over. The next page call knows nothing about the last page unless you use sessions to pass info. — DFriend

It is not possible to get form_validation message if you redirect. But you can use flashdata for this.

Add this $autoload['libraries'] = array('session'); in application/config/autoload.php and Put this code in your login page

if ($this->session->flashdata('basisdata_cek')) {
    echo '<div class="alert alert-warning">';
    echo '<p>' . $this->session->flashdata('basisdata_cek') . '</p>';
    echo '</div>';
  }

And put flash $this->session->set_flashdata instead $this->form_validation->set_message before redirect :

 }else{
    $this->session->set_flashdata('basisdata_cek', 'Invalid email or password');
    redirect(base_url('index.php/login'),'refresh');        
    return false;
  }
