Pengaturan Dasar Framework Codeigniter 4

Pengaturan Dasar Framework Codeigniter 4

Hallo Sobat Coding kembali bersama saya Admin BasisCoding postingan lalu kita sudah membahas tutorial instalasi codeigniter 4 via composer sekarang saya ingin memberikan tutorial tentang Pengaturan Dasar Framework Codeigniter 4

Struktur Folder Framework Codeigniter 4
Struktur Folder Codeigniter 4

gambar diatas adalah struktur folder pada Framework Codeigniter 4. jangan pusing yah πŸ˜€ kita akan fokus saja pada folder app

Struktur Folder App Codeigniter 4
Struktur Folder APP Codeigniter 4

nah gambar diatas adalah isi folder app, jangan pusing lagi karena saya akan jelaskan folder utama yang harus kalian pahami yaitu Config, Models, Controllers, Views.

sekarang kalian coba buka file app.php di folder config.

<?php namespace Config;

use CodeIgniter\Config\BaseConfig;

class App extends BaseConfig

	| and path to your installation. However, you should always configure this

	*/
	public $CSPEnabled = false;
}

pada file App.php tersebut kalian bisa mengatur pengaturan dasar seperti base_url, indexpage, timezone, dll.
nah fungsi folder Config ini adalah mengatur semua yang ada pada Framework ini seperti pengaturan aplikasi, database, email, routes dll.

sekarang kita coba pahami tentang controllers

Apa itu Controllers ?

Controllers merupakan sistem control yang dibuat sebagai jembatan yang bisa mengirim data ke views dan ke models. artinya ketika ada permintaan untuk menampilkan data pada views berarti akan melewati sebuah controller kemudian controller akan mengirim permintaan tersebut ke dalam suatu models.

Views merupakan sebuah sistem yang berfungsi sebagai User Interface atau sesuatu yang ingin ditampilkan kepada pengguna aplikasi kita.

Models merupakan sistem yang terhubung kepada suatu database, models ini akan menerima permintaan dari controllers danakan mengirim kembali kepada controller dalam bentuk data.

mudah-mudahan kalian mengerti penjelasan yang saya jelaskan πŸ˜€

dibawah ini saya berikan contoh dari ketiga sistem tersebut.

Controllers

<?php namespace App\Controllers;
class Home extends BaseController
{
	public function index()
	{
		return view('welcome_message');
	}
}

syntax diatas saya ambil dari Controller Home yang ada pada folder Controllers, pada syntax tersebut terdapat function index yang berfungsi ketika sebuah controller di panggil seperti contoh http://localhost:8080/Home maka akan mengeksekusi syntax didalamnya yaitu menampilkan file welcome_message.php di folder views.

Models

<?php namespace App\Models;

	Use CodeIgniter\Model;

	/**
	 * By Ahmad Fatoni
	 * Software Engineer in BasisCoding
	 */
	class Users extends Model
	{
		function getView()
		{
			$tb = $this->db->table('users');
			return $tb->get();
		}
	}
?>

model diatas adalah model Users yang saya buat untuk menampilkan data dari table users.

untuk folder views kalian bisa isi dengan syntax HTML biasa.

mungkin itu saja yang bisa saya berikan , jika ada pertanyaan silahkan tulis komentar dibawah postingan ini

terima kasih
