How to show continued numbered of data with pagination - codeigniter

Question

I am trying to display data in an ordered list with pagination in codeigniter. The numbered works fine in first page number 1 until limit, but in the next page it counts down start to 1, not continuing from previous page.
here is the controller code :
public function index()
{
// init params
$params = array();
$limit_per_page = 2;
$start_index = ($this->uri->segment(3)) ? $this->uri->segment(3) : 0;
$total_records = $this->model_pesan->get_total();
$data['setting'] = $this->setting_model->get_file();
if ($total_records > 0)
{
// get current page records
$params["results"] = $this->model_pesan->get_current_page_records($limit_per_page, $start_index);
$params["ruangan"] = $this->ruangan_model->get_file();
$config['base_url'] = base_url() . 'home/index';
$config['total_rows'] = $total_records;
$config['per_page'] = $limit_per_page;
$config["uri_segment"] = 3;
$config['full_tag_open'] = '<nav><ul class="pagination justify-content-center">';
$config['full_tag_close'] = '</ul></nav>';
$config['num_tag_open'] = '<li class="page-item"><span class="page-link">';
$config['num_tag_close'] = '</span></li>';
$config['cur_tag_open'] = '<li class="page-item active"><span class="page-link">';
$config['cur_tag_close'] = '<span class="sr-only">(current)</span></span></li>';
$config['next_tag_open'] = '<li class="page-item"><span class="page-link">';
$config['next_tagl_close'] = '<span aria-hidden="true">»</span></span></li>';
$config['prev_tag_open'] = '<li class="page-item"><span class="page-link">';
$config['prev_tagl_close'] = '</span></li>';
$config['first_tag_open'] = '<li class="page-item"><span class="page-link">';
$config['first_tagl_close'] = '</span></li>';
$config['last_tag_open'] = '<li class="page-item"><span class="page-link">';
$config['last_tagl_close'] = '</span></li>';
$this->pagination->initialize($config);
// build paging links
$params["links"] = $this->pagination->create_links();
}
$this->load->view('template/header_user', $data);
$this->load->view('user/home', $params);
$this->load->view('template/footer_user', $data);
}
and this is the model code :
public function get_current_page_records($limit, $start)
{
$query = $this->db->query('set #row_number = 0');
$this->db->select('(#row_number:=#row_number + 1) as num ,reservasi.id_reservasi,DATE_FORMAT(reservasi.tanggal, "%d-%m-%Y") as tanggal, reservasi.acara, reservasi.waktu_mulai, reservasi.waktu_selesai, reservasi.keterangan, ruangan.nama_ruangan, user.nama, reservasi.organisasi, reservasi.notelp');
$this->db->from('reservasi');
$this->db->join('user', 'reservasi.id_user = user.id');
$this->db->join('ruangan', 'reservasi.id_ruangan = ruangan.id_ruangan');
$this->db->limit($limit, $start);
$query = $this->db->get();
if ($query->num_rows() > 0)
{
foreach ($query->result() as $row)
{
$data[] = $row;
}
return $data;
}
return false;
}
public function get_total()
{
return $this->db->count_all_results('reservasi');
}
the ouput should be =
first page :
1
2
3
4
then in the next page :
5
6
7
8

Answer 1

Try to set the row_number to $start+1 instead of 0 on the model, so it will not start from 0 again on every page requested :
$query = $this->db->query('set #row_number = '.$start+1);
