207

Tutorial Codeigniter versi 4 kali ini kita akan mmbuat CRUD menampilkan data dari database, itu artinya kita akan bermain-main dengan database.

Karena kita ingin menampilkan data dari database menggunakan Codeigniter 4, maka kita membutuhkan sebuah database dan tabel, utungnya sebelumnya kita sudah pernah membuat database dan tabel yaitu “tbl_kelas” dimana perna kita buat pada tutorial-tutorial sebelumnya.

Menampilkan Data Dari Database Dengan Codeigniter 4
Berikut adalah langkah-langkahnya untuk menampilkan data dari database dengan Codeigniter versi 4.

Pertama, buatlah sebuah model dengan nama “Kelas_model.php” pada folder “app/Models” kemudian ketikkan kode seperti berikut:

<?php namespace App\Models;

use CodeIgniter\Model;

class Kelas_model extends Model
{
    protected $table = 'tbl_kelas';
    protected $primaryKey = 'id_kelas';
     
    public function getKelasAll()
    {
         return $this->findAll();       
    }
 
}

Pada model “Kelas_model.php” diatas, Codeigniter langsung mengetahui table yang digunakan yaitu table “tbl_kelas” yang telah di set melalui kode berikut:

protected $table = 'tbl_kelas';

Langkah kedua, adalah membuat sebuah file controller dengan nama “Kelas.php” pada folder “app/Controllers” kemudian ketikkan kode seperti berikut:

<?php namespace App\Controllers;

use CodeIgniter\Controller;
use App\Models\Kelas_model; //memanggil model

class Kelas extends BaseController
{
	public function index()
	{
		$model	= new Kelas_model();
		$data	= array();
        $data['kelas'] = $model->getKelasAll();
		return view('kelas',$data);
	}
	

}

Langkah ketiga, adalah membuat sebuah file view dengan nama “kelas.php” pada folder “app/Views”, untuk membuat file view “kelas.php” kita manfaatkan default view nya Codeigniter, oke mari kita duplicate file “welcome_message.php” dan ubahlah menjadi “kelas.php” dan rubahlah kodenya menjadi seperti berikut:
