code igniter pagination for displaying specific data from database? - codeigniter

Question

I want to display some specific data from database through pagination using CI.but pagination by default passess parameter in function which creates problem for me.
Here is my Controller
function page($catagoryid){
$this->load->library('pagination');
$config['base_url'] = base_url().'index.php/pagination/page/';
$count = $this->db->query("select * from tbl_products where category_id='$categoryid'");
$total=$count->num_rows();
$per_page = 4;
$config['total_rows'] = $total;
$config['per_page'] = $per_page;
$this->pagination->initialize($config);
$data['pagination'] = $this->pagination->create_links();
$this->load->model("mpagination");
$data['list'] = $this->mpagination->get_s(,$categoryid,$config['per_page'],$this->uri->segment(3));
if ($data['list']!== null){
$this->load->view('pagination_view', $data);
}
else {
$this->load->view('noresult');
}
}
Here is my Model
function get_s($categoryid,$num, $offset) {
$this->db->select ('*');
->where('category_id',$categoryid); // field name
$sql = $this->db->get('tbl_products',$num, $offset); // table name
if ($sql->num_rows () >0) {
return $sql->result();
}
else {
return null;
}
}
Here is my view
<?php
foreach($list as $row):?>
<?php echo $row->_prduct_id." ".$row->name." ".$row->description;?>
<br/>
<?php endforeach;?>
<br/>
<?php echo $pagination; ?>
This code work at first but when i clicked on second link of pagination it will not work because by default pagination sends its value to url as parameter and doesnot show data.
what can i do?

Answer 1

I didn't understand your code properly but this is the way you need to do pagination.
public function page($category_id)
{
$result = $this->model_file->model_function($category_id);
$start_index = 0;
$total_rows = count($result);
$items_per_page = 10;
$filtered = array_splice($result,$start_index,$items_per_page);
$model['data'] = $filtered;
$model['page_link'] = create_page_links (base_url()."/controller_file_name/page", $items_per_page, $total_rows);
$this->load->view('view_file_name_path',$model);
}
function create_page_links($base_url, $per_page, $total_rows) {
$CI = & get_instance();
$CI->load->library('pagination');
$config['base_url'] = $base_url;
$config['total_rows'] = $total_rows;
$config['per_page'] = $per_page;
$CI->pagination->initialize($config);
return $CI->pagination->create_links();
}

Try like this
public function index($offset = 0)
{
$language_id = 1;
$this->load->library('pagination');
$limit = 10;
$total = $this->legend_model->get_legend_count($language_id);
$config['base_url'] = base_url().'legend/index/';
$config['total_rows'] = $total;
$config['per_page'] = $limit;
$config['uri_segment'] = 3;
$config['first_link'] = '<< First';
$config['last_link'] = 'Last >>';
$config['next_link'] = 'Next ' . '>';
$config['prev_link'] = '<' . ' Previous';
$config['num_tag_open'] = '<span class="number">';
$config['num_tag_close'] = '</span>';
$config['cur_tag_open'] = '<span class="current"><a href="#">';
$config['cur_tag_close'] = '</a></span>';
$this->pagination->initialize($config);
$data['offset'] = $offset;
$data['legends'] = $this->legend_model->get_legend($language_id, $limit, $offset);
$this->template->write('title', 'Legend : Manage Legend');
$this->template->write_view('content', 'legend/index', $data);
$this->template->render();
}
