Make Pagination with search filter in CodeIgniter 4

CodeIgniter already has a pagination library using which you can easily add pagination on your page.

In this tutorial, I show how you can create pagination with a search filter in the CodeIgniter 4 project.

1. Database configuration

  • Open .env file which is available at the project root.

NOTE – If dot (.) not added at the start then rename the file to .env.

  • Remove # from start of database.default.hostname, database.default.database, database.default.username, database.default.password, and database.default.DBDriver.
  • Update the configuration and save it.
database.default.hostname = 127.0.0.1
database.default.database = testdb
database.default.username = root
database.default.password = 
database.default.DBDriver = MySQLi

2. Create Table

  • Create a new table users using migration.
php spark migrate:create create_users_table
  • Now, navigate to app/Database/Migrations/ folder from the project root.
  • Find a PHP file that ends with create_users_table and open it.
  • Define the table structure in the up() method.
  • Using the down() method delete users table which calls when undoing migration.
<?php namespace App\Database\Migrations;

use CodeIgniter\Database\Migration;

class CreateUsersTable extends Migration
{
    public function up() {
       $this->forge->addField([
          'id' => [
              'type' => 'INT',
              'constraint' => 5,
              'unsigned' => true,
              'auto_increment' => true,
          ],
          'name' => [
              'type' => 'VARCHAR',
              'constraint' => '100',
          ],
          'email' => [
              'type' => 'VARCHAR',
              'constraint' => '100',
          ],
          'city' => [
              'type' => 'VARCHAR',
              'constraint' => '100',
          ],
       ]);
       $this->forge->addKey('id', true);
       $this->forge->createTable('users');
    }

    //--------------------------------------------------------------------

    public function down() {
       $this->forge->dropTable('users');
    }
}
  • Run the migration –
php spark migrate

3. Model

  • Create Users.php file in app/Models/ folder.
  • Open the file.
  • Specify table name "users" in $table variable, primary key "id" in $primaryKey, Return type "array" in $returnType.
  • In $allowedFields Array specify field names – ['name', 'email','city'] that can be set during insert and update.

Completed Code

<?php 
namespace App\Models;

use CodeIgniter\Model;

class Users extends Model
{
    protected $table = 'users'; 
    protected $primaryKey = 'id';

    protected $returnType = 'array';

    protected $allowedFields = ['name', 'email','city'];
    protected $useTimestamps = false;

    protected $validationRules = [];
    protected $validationMessages = [];
    protected $skipValidation = false;

}

4. Route

  • Open app/Config/Routes.php file.
  • Define 2 routes –
    • /
    • loadRecord – Create pagination.

Completed Code

$routes->get('/', 'UsersController::index');
$routes->get('loadRecord', 'UsersController::loadRecord');

5. Controller

Create UsersController.php file in app/Controllers/ folder.

Create 2 methods –

  • index() – Redirect to 'loadRecord' route.
  • loadRecord() – Using this method create pagination.

Read search value and assign to $search variable. Create object of Users Model.

Call paginate() method on the $users object and pass a number (how many rows display per page).

If $search is not empty then search $search in name, email, and city fields using like().

Initialize $data Array with –

$data = [
   'users' => $paginateData,
   'pager' => $users->pager,
   'search' => $search
];

Pass fetched data to 'users' key, $users->pager to 'pager', and $search to 'search' key.

Using 'users' key access fetched data in view and with 'pager' key create pagination links.

Load index view and pass $data.

Completed Code

<?php namespace App\Controllers;

use App\Models\Users;

class UsersController extends BaseController{

  public function index(){
    return redirect()->route('loadRecord');
  }

  public function loadRecord(){
    $request = service('request');
    $searchData = $request->getGet();

    $search = "";
    if(isset($searchData) && isset($searchData['search'])){
       $search = $searchData['search'];
    }

    // Get data 
    $users = new Users();

    if($search == ''){
      $paginateData = $users->paginate(5);
    }else{
      $paginateData = $users->select('*')
          ->orLike('name', $search)
          ->orLike('email', $search)
          ->orLike('city', $search)
          ->paginate(5);
    }

    $data = [
      'users' => $paginateData,
      'pager' => $users->pager,
      'search' => $search
    ];

    return view('index',$data); 
  }

}

6. View

Create index.php file in app/Views.

Create <form method='get' action="loadRecord" id="searchForm"> and add a textbox and a button. Add onclick event on button to submit the <form >.

Loop on the $users to list fetched records.

Display pagination link using $pager->links().
