For this, you can use server side datatable in codeigniter 4 app. So it will take you only condsse to display thousands of data with sorting, searching, filtering and pagination.

Note that, DataTables is a jQuery (Javascript library) based table advancement plug-in, It brings coherence in the data analysis process, ideally offers adding, sorting, pagination and filtering abilities to plain HTML tables with minimal effort.

Codeigniter 4 datatables server side tutorial; In this example, I will first install jquery datatable and then show a list on the web page using server side data with dataTable.

Codeigniter 4 Datatables Server Side Example

Use the below given steps to implement dataTable server side in Codeigniter 4 apps:

  • Install Codeigniter 4 Application
  • Basic App Configurations
  • Create Database and Table
  • Setup Database Credentials
  • Installing CodeIgniter4-DataTables Library
  • Create Model Class
  • Create Controller Class
  • Create Views
  • Setup Routes
  • Start Development server

Step 1 – Install Codeigniter 4 Application

First of all, you need to ownload the latest version of Codeigniter 4. So, visit this link https://codeigniter.com/download Download Codeigniter 4 app and unzip the setup in your local system xampp/htdocs/ .

Note that, please change the download folder name “demo”.

Step 2 – Basic App Configurations

Now, you need to some basic configuration on the app/config/app.php file, so let’s go to application/config/config.php and open this file on text editor.

Set Base URL like this

public $baseURL = 'http://localhost:8080';
To
public $baseURL = 'http://localhost/demo/';

Step 3 – Create Database and Table

Create a database and table by executing the following SQL query:

CREATE DATABASE demo;

CREATE TABLE users (
    id int(11) NOT NULL AUTO_INCREMENT COMMENT 'Primary Key',
    name varchar(100) NOT NULL COMMENT 'Name',
    email varchar(255) NOT NULL COMMENT 'Email Address',
    PRIMARY KEY (id)
) ENGINE=InnoDB DEFAULT CHARSET=latin1 COMMENT='demo database' AUTO_INCREMENT=1;

INSERT INTO `users` (`id`, `name`, `email`) VALUES
(1, 'Paul Bettany', '[email protected]'),
(2, 'Vanya', '[email protected]'),
(3, 'Luther', '[email protected]'),
(4, 'John Doe', '[email protected]'),
(5, 'Paul Bettany', '[email protected]'),
(6, 'Vanya', '[email protected]'),
(7, 'Luther', '[email protected]'),
(8, 'Wayne Barrett', '[email protected]'),
(9, 'Vincent Ramos', '[email protected]'),
(10, 'Susan Warren', '[email protected]'),
(11, 'Jason Evans', '[email protected]'),
(12, 'Madison Simpson', '[email protected]'),
(13, 'Marvin Ortiz', '[email protected]'),
(14, 'Felecia Phillips', '[email protected]'),
(15, 'Tommy Hernandez', '[email protected]');

Step 4 – Setup Database Credentials

To connect your codeigniter 4 app to the database. So, visit app/Config/ directory and open Database.php. Then add the databasae details like below into database.php file:

public $default = [
        'DSN'      => '',
        'hostname' => 'localhost',
        'username' => 'test',
        'password' => '4Mu99BhzK8dr4vF1',
        'database' => 'demo',
        'DBDriver' => 'MySQLi',
        'DBPrefix' => '',
        'pConnect' => false,
        'DBDebug'  => (ENVIRONMENT !== 'development'),
        'cacheOn'  => false,
        'cacheDir' => '',
        'charset'  => 'utf8',
        'DBCollat' => 'utf8_general_ci',
        'swapPre'  => '',
        'encrypt'  => false,
        'compress' => false,
        'strictOn' => false,
        'failover' => [],
        'port'     => 3306,
	];

Step 5 – Installing CodeIgniter4-DataTables Library

To install datatable pluing by executing the following comamnd on terminal:

composer require hermawan/codeigniter4-datatables

then open app/Config/autoload.php. add namespace to $psr4 array. see the code below:

public $psr4 = [
    APP_NAMESPACE => APPPATH, // For custom app namespace
    'Config'      => APPPATH . 'Config',
    'PHPSQLParser'          => APPPATH .'ThirdParty/php-sql-parser/src/PHPSQLParser',
    'Hermawan\DataTables'   => APPPATH .'ThirdParty/CodeIgniter4-DataTables/src'
];

Step 6 – Create Model Class

Create UserModel.php file. So, visit app/Models/ directory and create UserModel.php.Then add the following code into it:

<?php 
namespace App\Models;
use CodeIgniter\Model;

class UserModel extends Model
{
    protected $table = 'users';
    protected $primaryKey = 'id';
    protected $allowedFields = ['name', 'email'];
}

Step 7 – Create Controller Class

Create UsersController.php file. So, visit app/Controllers directory and create UsersController.php.Then add the following code into it:

<?php namespace App\Controllers;
 
use \CodeIgniter\Controller;

use \Hermawan\DataTables\DataTable;
 
class UsersController extends Controller
{
    public function index()
    {
        helper('url');
        return view('list');
    }
 
    public function ajaxDataTables()
    {
        $db = db_connect();
        $builder = $db->table('users')->select('name, email, id');
         
        return DataTable::of($builder)
               ->addNumbering() //it will return data output with numbering on first column
               ->toJson();
    }
}
 
?>

UserCrudController crud controller’s methods will work as follows:

  • The index() function renders the users list template into the view.
  • The ajaxDataTables() function fetch data into database using ajax.

Step 8 – Create Views

Create list.php view file, so visit app/views/ directory and create list.php file. Then add the following HTML into list.php file:

<!DOCTYPE html>
<html>
<head>
    <meta charset="utf-8">
    <meta http-equiv="X-UA-Compatible" content="IE=edge">
    <meta name="viewport" content="width=device-width, initial-scale=1">
    <title></title>

            <thead>
                <tr>
                    <th>No</th>
                    <th>Name</th>
                    <th>Email</th>
                </tr>
            </thead>
            <tbody></tbody>
            <tfoot>
                <tr>
                    <th>No</th>
                    <th>Name</th>
                    <th>Email</th>
                </tr>
            </tfoot>
        </table>

    <script type="text/javascript">
 
    $(document).ready(function() {
        $('#table').DataTable({ 
            processing: true,
            serverSide: true,
            order: [], //init datatable not ordering
            ajax: "<?php echo site_url('ajax-datatable')?>",
            columnDefs: [
                { targets: 0, orderable: false}, //first column is not orderable.
            ]
        });
    });
    </script>
 
</body>
</html>

Step 9 – Setup Routes

To define a route, So, visit app/Config/ directory and open Routes.php file. Then add the following routes into it:

// CRUD RESTful Routes
$routes->setDefaultController('UsersController');
$routes->get('list', 'UsersController::index');
$routes->get('ajax-datatable', 'UsersController::ajaxDataTables');

Note that, the routes will be display data from server side on view.

Step 10 – Start Development server

Execute the following command into command prompt or terminal to start the codeigniter 4 application:

php spark serve

Then visit your web browser and hit the following url on it:

http://localhost/demo/

OR

http://localhost:8080/
