Stacked in Pagination in Codeigniter - codeigniter

Question

i'm new with CI and i tried a lot posibilities to make this run, but still it ain't working. Could you please tell me what i'm doing wrong?
So, Controller:
<?php if ( ! defined('BASEPATH')) exit('No direct script access allowed');
class News extends CI_Controller {
public function __construct()
{
parent::__construct();
$this->load->model('model_add','',TRUE);
}
public function _remap($a){
if (isset($a) && !empty($a)):
switch ($a) {
case 'index':
$this->index();
break;
default:
$this->one_news($a);
break;
}
endif;
}
public function index()
{
$this->load->library('pagination');
$home=$this->uri->segment(2);
$limit=2;
$offset=0;
$query=$this->model_add->count_news($limit,$offset);
$config['base_url'] = base_url().'/news/';
$config['total_rows'] = $this->db->count_all('tdt_news');
$config['per_page'] = 2;
$config['uri_segment'] = 2;
$this->pagination->initialize($config);
$data = array('query' => $query,'page'=>$home);
$data['news'] = $query;
$this->load->view('main/header');
$this->load->view('main/news', $data);
$this->load->view('main/footer');
}
}
And the Model:
function count_news()
{
$query=$this->db->query("SELECT * FROM `tdt_news` ORDER BY `id` DESC LIMIT $limit, $offset;");
return $query->result();
}
I'll be very thankful for your help, thank you!

You have a series of errors
your count function in your model is missing parameters
you should reformat the SQL string
alternate and standard syntax in your view
renamed model class to empty string
heres a fixed version,
Controller:
<?php if ( ! defined('BASEPATH')) exit('No direct script access allowed');
class News extends CI_Controller {
public function __construct()
{
parent::__construct();
$this->load->model('model_add');
}
public function _remap($a){
if (isset($a) && !empty($a)) {
switch ($a) {
case 'index':
$this->index();
break;
default:
$this->one_news($a);
break;
}
}
}
public function index()
{
$this->load->library('pagination');
$home = $this->uri->segment(2);
$limit = 2;
$offset = 0;
$query=$this->model_add->count_news($limit,$offset);
$config['base_url'] = base_url().'/news/';
$config['total_rows'] = $this->db->count_all('tdt_news');
$config['per_page'] = 2;
$config['uri_segment'] = 2;
$this->pagination->initialize($config);
$data = array( 'query' => $query,
'page'=>$home,
'news' => $query);
$this->load->view('main/header');
$this->load->view('main/news', $data);
$this->load->view('main/footer');
}
}
Model:
// with default parameters just in case
function count_news($limit = 50, $offset = 0)
{
// and there is a nicer way to write your query
// it works with multiple dbs thanks to active record
$this->db->order_by('id','desc');
$query = $this->db->get('tdt_news', $limit, $offset);
return $query->result();
}
