$data['title'] = "User Article";
$config = array();
$config["base_url"] = base_url() . 'article/user_article/?rc='. $rc ;
$config["total_rows"] = $this->article_m->record_count_uarticles($_GET);
$config["per_page"] = 1;
$config["uri_segment"] = 3;
$this->pagination->initialize($config);
$page = ($this->uri->segment(3)) ? $this->uri->segment(3) : 0;
$data["results"] = $this->article_m->fetch_result_uarticles($_GET, $config["per_page"], $page);
$data["links"] = $this->pagination->create_links();
if ($this->session->userdata ('is_logged_in')){
$data['profile']=$this->model_users->profilefetch();
$this->load->view('header',$data);
$this->load->view('user_article', $data);
$this->load->view('sfooter', $data);
} else {
redirect('signin');
}
}

public function record_count_uarticles($rc) {
$query=$this->db->select('email,writer')->where('rc',$rc['rc'])->get('users');
$result=$query->result_array();
if ($query->num_rows() > 0) {
$row = $query->row_array();
$array = array ('email' => $row['email'], 'status' => '1');
return $this->db->where($array)->count_all_results("articles");
}
}
public function fetch_result_uarticles($rc, $limit, $start) {
$query=$this->db->select('email,writer')->where('rc',$rc['rc'])->get('users');
$result=$query->result_array();
if ($query->num_rows() > 0) {
$row = $query->row_array();
$this->db->limit($limit, $start);
$array = array ('u.email' => $row['email'], 'a.status' => '1', 'u.writer' => '1');
$query1=$this->db->select('a.id,title,a.status,description,image,a.email,tags,postdate,firstname,lastname,rc')->join('users u','u.email = a.email','left')->where($array)->order_by('a.id', 'DESC')->get('articles a');
if ($query1->num_rows() > 0) {
foreach ($query1->result() as $row) {
$data[] = $row;
}
return $data;
}
return false;
}
}
Check this code, pagination show properly, first page article print correctly but after click on pagination link then no article print in scnd page
This Link work but default link is not work , is there any query to change the url
../project/article/user_article/?rc=4715422/1 -- Default Link Not Work
../project/article/user_article/1/?rc=4715422 -- Custom Edited Link work
