Error in generating page number links using Codeigniter - php

Question

I am creating a pagination using Codeigniter and my problem is I have an error in displaying the page number links in my URL.
example I go to page 2 my URL would be like this:
http://localhost/my_project/inbound/listing/1
if page 3
http://localhost/my_project/inbound/listing/2
Here's my controller
$config = array();
$config['base_url'] = base_url('inbound/listing');
$config['total_rows'] = $this->mod->countList();
$config['per_page'] = 1;
$config['uri_segment'] = 3;
//fd($config);
$this->pagination->initialize($config);
$page = ($this->uri->segment(3)) ? $this->uri->segment(3) : 0;
fp($page, 'pink'); //print out result
$order = ($this->input->get('order'))? $this->input->get('order'): '';
$sort = ($this->input->get('sort'))? $this->input->get('sort'): '';
// Query data
$data['data_list'] = $this->mod->listing($config['per_page'], $page); //where, limit, page, field, sort
fP($data['data_list']); //print out result
$data['pagination'] = $this->pagination->create_links();
Then my model for generating links:
function listing($limit, $start)
{
//DATE_FORMAT(`post_date_added`, "%m/%d/%Y %H:%i") as `proper_post_date_added`,
$this->db->select('*');
$this->db->from('inventory');
$this->db->limit($limit, $start);
$query = $this->db->get();
//$rows = $query->result_array();
if($query->num_rows() > 0) {
foreach($query->result() as $row) {
$data[] = $row;
}
return $data;
}
return false;
}
Can you help me with this?

If you want to go to page number based on your url, modify your listing function to be like this:
function listing($limit, $start)
{
$offset_1 = $start - $limit;
$offset_2 = $offset_1 < 0 ? 0 : $offset_1;
//DATE_FORMAT(`post_date_added`, "%m/%d/%Y %H:%i") as `proper_post_date_added`,
$this->db->select('*');
$this->db->from('inventory');
$this->db->limit($limit, $offset_2);
$query = $this->db->get();
//$rows = $query->result_array();
if($query->num_rows() > 0) {
foreach($query->result() as $row) {
$data[] = $row;
}
return $data;
}
return false;
}
