Reading Time: 8 minutes

Inside this article we will see the concept i.e CodeIgniter 4 How To Work with Pagination Library Tutorial. Article contains the classified information about How to Create Pagination in Codeigniter 4 Application.

As we know, in a real time application we store a huge amount of data. They grow as application grows by time. When we design application, we need to take care that how users will browse data at site when we need to show data in bulk.

Now, here Pagination service will comes into play. It allows to break down the results or data sets into small manageable parts. As you can see here how google manages it’s pagination links when it shows many records on the basis of search keyword.

Let’s get started.

CodeIgniter 4 Installation

To create a CodeIgniter 4 setup run this given command into your shell or terminal. Please make sure composer should be installed.

composer create-project codeigniter4/appstarter codeigniter-4

Assuming you have successfully installed application into your local system.

Environment (.env) Setup

When we install CodeIgniter 4, we will have env file at root. To use the environment variables means using variables at global scope we need to do env to .env

Either we can do via renaming file as simple as that. Also we can do by terminal command.

Open project in terminal

cp env .env

Above command will create a copy of env file to .env file. Now we are ready to use environment variables.

Enable Development Mode

CodeIgniter starts up in production mode by default. You need to make it in development mode to see any error if you are working with application.

Open .env file from root.

# CI_ENVIRONMENT = production

 // Do it to 
CI_ENVIRONMENT = development

Now application is in development mode.

What is CodeIgniter 4 Pagination Service?

CodeIgniter provides a pre defined library or service which provides a pagination feature. This pagination feature enables or breakdowns the huge data into clickable links which design application and manages in a great way.

In CodeIgniter 4, we can also say it as Pagination service. Now, let’s see how can we load it?

For Pagination we have a service defined in CodeIgniter 4, it will be

$pager = \Config\Services::pager();


$pager = service("pager");

Let’s see by making a practical example.

Create Database

To create a database, either we can create via Manual tool of PhpMyadmin or by means of a mysql command.

We will use MySQL command to create database. Run this command into Sql tab of PhpMyAdmin.

CREATE DATABASE codeigniter4_app;

Successfully, we have created a database.

Create Database Table & Test Data

Next, we need a table. That table will be responsible to store data.

Let’s create table with some columns.

CREATE TABLE tbl_students (
    name varchar(120) DEFAULT NULL,
    email varchar(120) DEFAULT NULL,
    mobile varchar(45) DEFAULT NULL,
    PRIMARY KEY (id)

Successfully, we have created a table.

Let’s dump test data into it.

-- Dumping data for table `tbl_students`

INSERT INTO `tbl_students` (`id`, `name`, `email`, `mobile`) VALUES
(1, 'Sanjay Kumar', '', '9632587410'),
(2, 'Vijay Kumar', '', '7418529630'),
(3, 'Rakesh Kumar', '', '8527410963'),
(4, 'Kavita Singh', '', '8529647130'),
(5, 'Ashish Kumar', '', '7410852963'),
(6, 'Dhananjay Negi', '', '7896541230'),
(7, 'Pradeep Goyal', '', '1234567890'),
(8, 'Nilu Singh', '', '7026358941');

Run this query to created database, it will insert these dummy data into tbl_students table.

Database Connection

Open .env file from project root.

Search for DATABASE. You should see the connection environment variables into it. Put your updated details of database connection string values.


database.default.hostname = localhost
database.default.database = codeigniter4_app
database.default.username = admin
database.default.password = admin
database.default.DBDriver = MySQLi
database.default.DBPrefix =
database.default.port = 3306

Now, database successfully connected with the application.

Create Route

Open Routes.php from /app/Config folder. Add this route into it.


$routes->get("list-student", "Student::listStudent");


Let’s create Model.

Set Application Model

Model is the face of application with the database. We need a Student Model where we will do some basic model configuration.

Models are created at /app/Models. We are going to create StudentModel.php at this location.

$ php spark make:model Student --suffix

It will create StudentModel.php at /app/Models folder. Open file and write this complete code into it.


namespace App\Models;

use CodeIgniter\Model;

class StudentModel extends Model
	protected $DBGroup              = 'default';
	protected $table                = 'tbl_students';
	protected $primaryKey           = 'id';
	protected $useAutoIncrement     = true;
	protected $insertID             = 0;
	protected $returnType           = 'array';
	protected $useSoftDelete        = false;
	protected $protectFields        = true;
	protected $allowedFields        = [

	// Dates
	protected $useTimestamps        = false;
	protected $dateFormat           = 'datetime';
	protected $createdField         = 'created_at';
	protected $updatedField         = 'updated_at';
	protected $deletedField         = 'deleted_at';

	// Validation
	protected $validationRules      = [];
	protected $validationMessages   = [];
	protected $skipValidation       = false;
	protected $cleanValidationRules = true;

	// Callbacks
	protected $allowCallbacks       = true;
	protected $beforeInsert         = [];
	protected $afterInsert          = [];
	protected $beforeUpdate         = [];
	protected $afterUpdate          = [];
	protected $beforeFind           = [];
	protected $afterFind            = [];
	protected $beforeDelete         = [];
	protected $afterDelete          = [];

Application Controller Settings

Controller is the functional file.

We will create application controller inside /app/Controllers.

Let’s create Student.php inside the given folder. Open project into terminal and run this.

$ php spark make:controller Student

Open & write the complete code into Student.php file


namespace App\Controllers;

use App\Models\StudentModel;

class Student extends BaseController
    public function listStudent()
        $studentModel = new StudentModel();
        return view('list-student', [
            "students" => $studentModel->paginate(3),
            "pager" => $studentModel->pager,
  • use App\Models\StudentModel; Loading model before use.
  • $studentModel = new StudentModel(); Creating model instance to use.
  • $studentModel->paginate(3) Using pagination service, 3 indicates per page records.
  • $studentModel->pager It creates an instance to call few methods which generated pagination links.

Let’s create view file.

Create View Layout

We need to create view file. View file for List Student.

Create list-student.php inside /app/Views folder. Open file and write this complete code into it.

        if(count($students) > 0){

            foreach($students as $index => $user){
                    <td><?php echo $user['id'] ?></td>
                    <td><?php echo $user['name'] ?></td>
                    <td><?php echo $user['email'] ?></td>

<?= $pager->links() ?>

Also, we can use $pager->simpleLinks() instead of $pager->links().

Application Testing

Open project terminal and start development server via command:

php spark serve

URL – http://localhost:8080/list-student

We should get the output as

Added few lines of CSS, it will be like

ul.pagination {
    list-style: none;
    display: flex;

li {
    padding: 5px;
