Answer 1

finally i got a solution for the redirect with validation_errors

This is using to pass the validation_errors in the session data, i do it like this

if ($this->form_validation->run()) {
        $data = array(
            'email' => $this->input->post('email'),
            'is_login' => true
        );
        $this->session->set_userdata($data);
        redirect($this->input->post('redirect'));
    }
    else
    {
        $data = array (
            'errors' => validation_errors(),
            'is_login' => false
        );
        $this->session->set_userdata($data);
        redirect($this->input->post('redirect'));
    }

and in the page i used

        $this->session->set_flashdata('redirectToCurrent', current_url());

    if ($this->session->userdata('is_login'))
    {
        echo "You are using this as : 
" . $this->session->userdata('email');
        echo "
Logout";
    }
    else
    {
        echo form_open('login');
        echo "" . $this->session->userdata('errors');
        echo "email : " . form_input('email');
        echo "Password : " . form_password('password');
        echo form_submit('submit', 'Login');
        echo form_hidden('redirect',$this->uri->uri_string());
        echo form_close();
    }
