Make pagination with CodeIgniter Framework

Pagination on the page improves the user experience when there is a large number of records are available.

CodeIgniter has provided a library for effectively handle the pagination functionality.

In this tutorial, I am using the pagination library to create the paginated list of fetched result from MySQL database.

1. Table structure

I am using users table.

CREATE TABLE `users` (
  `id` int(11) NOT NULL PRIMARY KEY AUTO_INCREMENT,
  `username` varchar(80) NOT NULL,
  `name` varchar(80) NOT NULL,
  `email` varchar(80) NOT NULL
) ENGINE=InnoDB DEFAULT CHARSET=latin1;

 

2. Configuration

Navigate to application/config/database.php and define Database connection.

$db['default'] = array(
 'dsn' => '',
 'hostname' => 'localhost',
 'username' => 'root', // Username
 'password' => '', // Password
 'database' => 'tutorial', // Database name
 'dbdriver' => 'mysqli',
 'dbprefix' => '',
 'pconnect' => FALSE,
 'db_debug' => (ENVIRONMENT !== 'production'),
 'cache_on' => FALSE,
 'cachedir' => '',
 'char_set' => 'utf8',
 'dbcollat' => 'utf8_general_ci',
 'swap_pre' => '',
 'encrypt' => FALSE,
 'compress' => FALSE,
 'stricton' => FALSE,
 'failover' => array(),
 'save_queries' => TRUE
);

Default controller

Open application/config/routes.php and edit default_controller value to User.

$route['default_controller'] = 'User';

Load Database

To access the MySQL database require loading database library.

Open application/config/autoload.php and add the database in libraries array().

$autoload['libraries'] = array("database");

Remove index.php from URL

Navigate to application/config/config.php and replace $config['index'] = "index.php"; with $config["index"] = "";.

  • Create .htaccess file in your project root directory.
  • Write following code in it –
RewriteEngine On
RewriteCond $1 !^(index\.php|resources|robots\.txt)
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^(.*)$ index.php?/$1 [L,QSA]

 

3. Model

Create application/models/User_model.php.

Create two function getData() and getrecordCount().

getData() – Fetch and return records from users table according to the $rowno and $rowperpage value.

getrecordCount() – Return total records in users table.

Completed Code

<?php 

if ( ! defined('BASEPATH')) exit('No direct script access allowed');
Class User_Model extends CI_Model {

 public function __construct() { 
   parent::__construct();  
 }

 // Fetch records 
 public function getData($rowno,$rowperpage) { 
   $this->db->select('*'); 
   $this->db->from('users');        
   $this->db->limit($rowperpage, $rowno);    
   $query = $this->db->get();        
   return $query->result_array(); 
 }

 // Select total records    
 public function getrecordCount() {
   $this->db->select('count(*) as allcount');      
   $this->db->from('users');      
   $query = $this->db->get();      
   $result = $query->result_array();            
   return $result[0]['allcount'];    
 }
}

 

4. Controller

Create a application/controllers/User.php.

Define a constructor, index(), and loadRecord() methods.

__construct() – Load pagination library using $this->load->library() and User_model.

index() – Redirect to loadRecord() method.

loadRecord() – Set $rowperpage to 5 and if $rowno value is not equal to 0 then $rowno = ($rowno-1) * $rowperpage.

Get the total records by calling getrecordCount() method and user records by calling getData() method where pass $rowno and $rowperpage value.

Set the pagination configuration.

Pass the $config to $this->pagination->initialize($config) and get the links with $this->pagination->create_links() and initialize $data['pagination'].

Pass the $user_record in $data['result'] and $rowno in $data['row'].

Load the user_view and pass the $data variable.

Completed Code

<?php
defined('BASEPATH') OR exit('No direct script access allowed');
class User extends CI_Controller {
 public function __construct(){         
   parent::__construct();        
   $this->load->helper('url');
   
   // Load Pagination library 
   $this->load->library('pagination');
   
   // Load model 
   $this->load->model('User_model'); 
 } 

 public function index() { 
   redirect('User/loadRecord'); 
 }

 public function loadRecord($rowno=0){
   // Row per page 
   $rowperpage = 5;
   
   // Row position 
   if($rowno != 0){ 
     $rowno = ($rowno-1) * $rowperpage; 
   }            

   // All records count      
   $allcount = $this->User_model->getrecordCount();

   // Get  records      
   $users_record = $this->User_model->getData($rowno,$rowperpage);   
         
   // Pagination Configuration      
   $config['base_url'] = base_url().'User/loadRecord';      
   $config['use_page_numbers'] = TRUE;      
   $config['total_rows'] = $allcount; 
   $config['per_page'] = $rowperpage;

   // Initialize 
   $this->pagination->initialize($config);

   $data['pagination'] = $this->pagination->create_links(); 
   $data['result'] = $users_record; 
   $data['row'] = $rowno;

   // Load view 
   $this->load->view('user_view',$data); 
  }
}

 

5. View

Create a new application/views/user_view.php file.

Display users record by looping on the $result variable and for display pagination with $pagination.

Completed Code

<?php
defined('BASEPATH') OR exit('No direct script access allowed');
?>
<!DOCTYPE html>
<html lang="en">
 <head> 
  <meta charset="utf-8"> <title>CodeIgniter</title>
  <style type="text/css"> 
  a { 
   padding-left: 5px; 
   padding-right: 5px; 
   margin-left: 5px; 
   margin-right: 5px; 
  } 
  </style>
 </head>
 <body>
  <table border='1' style='border-collapse: collapse;'> 
   <tr> 
    <th>S.no</th> 
    <th>Username</th> 
    <th>Name</th> 
    <th>Email</th> 
   </tr> 
   <?php  
    $sno = $row+1; 
    foreach($result as $data){ 
      echo "<tr>"; 
      echo "<td>".$sno."</td>"; 
      echo "<td>".$data['username']."</td>"; 
      echo "<td>".$data['name']."</td>"; 
      echo "<td>".$data['email']."</td>"; 
      echo "</tr>"; 
      $sno++; 
    } 
    ?> 
  </table>
  <!-- Paginate --> 
  <div style='margin-top: 10px;'> 
  <?= $pagination; ?> 
  </div>
 </body>
</html>

 

6. Conclusion

You need to load the pagination library and set the required configuration for initializing. Then create the paginate numeric links and use it in the view.

I have only used some of the configuration for pagination library you can learn more about it from here.
