Question

I am new to codeigniter, I am trying to create pagination on the records i am fetching from database. I have written the following code, its showing me pagination but its no

Answer 1

For a better use of pagination create a function in your helper. That will very useful for you for future use. you don't ever need to load library and other values. fix this function in your helper.

if( ! function_exists('createPaginationForm')) {
    function createPaginationForm($url, $totalRows, $perPage, $segment, $queryString = '', $config = array()) {
        $CI =& get_instance();
        $CI->load->library('pagination');
        $config['base_url'] = base_url().$url;
        $config['total_rows'] = $totalRows;
        $config['per_page'] = $perPage;
        $config['uri_segment'] = $segment;
        $CI->pagination->initialize($config);
        return $CI->pagination->create_links($queryString);
    }
}

and use in your controller .

var $perPage = '10';
var $segment = '4';
$total_result = "50";
$pagination = createPaginationForm('admin/news/index/',$total_result ,$this->perPage, $this->segment);
$this->data['pagination'] = $pagination;

and print this in your view.

echo $pagination

you need to some data to displat in pagination use query for this and $config['total_rows'] so it will display total result pagination with 5 records

in my case i am using $this->Account->search_users($where,false, false,false,true,false); is a model function will return array of result

return $query->result_array();

controller :-

      $this->load->library('pagination');   
    $config['total_rows'] = $this->Account->search_users($where,false, false,false,true,false);
    $config['per_page']= 5;
    $config['uri_segment'] = 3;
    $config['base_url']= base_url().'/app/index'; 
    $config['suffix'] = '?'.http_build_query($_GET, '', "&"); 
    $this->pagination->initialize($config);
    $this->data['paginglinks'] = $this->pagination->create_links();     
    $this->data['per_page'] = $this->uri->segment(3);       
    $this->data['offset'] = $offset ;

view:-

<div class="pagination" style="float:right;"> <?php echo $paginglinks; ?></div>

For more info :- http://ellislab.com/codeigniter/user-guide/libraries/pagination.html

my model function is :-

public function search_users($where = false, $num = false, $offset = false, $order_by = false, $count = false, $select = false , $table=false){

    if(!$select){$select = 'U.*';}

        if(isset($where['where']) && !empty($where['where'])) {
            $this->db->where($where['where']);
        }

        if($order_by){
            $this->db->order_by($order_by[0], $order_by[1]);
        }else{
            $this->db->order_by('U.u_id', 'DESC');
        }

        $query = $this->db->get($table . ' AS U');
        //print_r($this->db->last_query()).'<hr>';
        $recount = $query->num_rows;    
        if($count) {
            return $recount;    
        }

        if($recount > 0){
            return $query->result_array();
        }
        else{ 
            return false;
        }
    }

First Of All i suggest to create a helper function to configure your pagination like this. You gotta find out from codeigniter documention for the option purpose in config

if (!function_exists('getPaginationConfig')) {
    function getPaginationConfig($url,$total_row,$per_page,$num_links=3){
            $config = array();
            $config['use_page_numbers'] = TRUE;
            $config['uri_segment'] = 3;// depends on how you passing your page number
            $config['base_url'] = $url;
            $config['total_rows'] = $total_row;
            $config['per_page'] = $per_page; 
            $config['full_tag_open'] = '<ul>';
            $config['full_tag_close'] = '</ul>';
            $config['cur_tag_open'] = '<li class="active"><a href="">';
            $config['cur_tag_close'] = '</a></li>';
            $config['num_tag_open'] = '<li>';
            $config['num_tag_close'] = '</li>';
            $config['next_tag_open'] = '<li>';
            $config['next_tag_close'] = '</li>';
            $config['prev_tag_open'] = '<li>';
            $config['prev_tag_close'] = '</li>';
            $config['first_link'] = '&lt;&lt;';
            $config['first_tag_open'] = '<li>';
            $config['first_tag_close'] = '</li>';
            $config['last_link'] = '&gt;&gt;';
            $config['last_tag_open'] = '<li>';
            $config['last_tag_close'] = '</li>';
            $config['num_links'] = $num_links;

     return $config;        
   }
}

Now On Controller .. you need to get total rows from database and set the perpage in pagination and call with the config here is an example of controller function

 function getMyList($page){
        $limit = YOUR_PAGE_LIMIT;//may be some global variable or input from frontend
        $starting = ($page-1)*$limit;

        $data['results']  = $this->your_model->getListOfTable($where,$limit,$starting);
        $total_rows = $this->your_model->getTotalRowsOfTable($where);// where is filter condition

        $this -> load -> helper('your_helper');// where yours getPaginationConfig is defined
        $this -> load -> library('pagination');
        $this -> pagination -> initialize(getPaginationConfig(site_url('controller/function'), $total_rows,$limit));
        $data['pagination'] = $this -> pagination -> create_links();
        $this->load->view('yourview',$data);

Your model may look like this

function getListOfTable($where = array(), $limit, $starting = 0) {
        $this -> db -> select('*');
        // <-- There is never any reason to write this line!
        $this -> db -> from('your_tables');
        if (!empty($where))
           $this -> db -> where($where);
        $this -> db -> limit($limit, $starting);
        $query = $this -> db -> get();

        if ($query -> num_rows() > 0) {
            return $query -> result();
        } else {
            return FALSE;
        }
    }

function getTotalRowsOfTable($where = array()){
    if (!empty($data))
         $this -> db -> where($where);
    $this -> db -> from('your_table');
    return $this -> db -> count_all_results();

}

Now On View you just need to echo the pagination where you like

  <div id="pagination"><?php echo $pagination;?></div>

Controller:

public function all_students() 
 {      $this->load->model('loginmodel');
        $config['anchor_class'] = '';
        $config['show_count'] = true;
        $config['base_url'] = site_url('controllername/all_students');
        $config['total_rows'] = sizeof($this->loginmodel->students_list());

        $data['students_data']= $this->loginmodel->students_list();
        $data['dropdown']=      $this->loginmodel->get_degree_names();
        $config['per_page'] = 10;
        $this->jquery_pagination->initialize($config);
        $data['links'] = $this->jquery_pagination->create_links();
        $data['page'] = ($this->uri->segment(3)) ? $this->uri->segment(3) : 0;
        $data['details'] = $this->loginmodel->students_list($config['per_page'], $data['page']);
        $this->load->view('all_students', $data);
    }

Model

public function students_list($limit=NULL,$start=NULL)
{


    $this->db->select('*');
    $this->db->from('student'); 

    $this->db->limit($limit,$start);                

    $query= $this->db->get();

    return $query->result();

 }
