Manajemen Query & Ekstraksi Data Efisien Di Crud Codeigniter 4 Dengan Bootstrap — Part 3

Membangun aplikasi web di era modern memerlukan pondasi yang kokoh. Framework modern memberikan fleksibilitas luar biasa bagi developer untuk menghadirkan fitur kompleks secara cepat tanpa mengabaikan aspek keamanan dan keandalan sistem.

Tahapan Implementasi & Walkthrough Kode

Berikut adalah langkah demi langkah teknis yang dapat Anda ikuti langsung pada codebase Anda:

Tahap 1: Penulisan Kode & Konfigurasi

<?php namespace App\Models;

use CodeIgniter\Model;

class PostModel extends Model
{
    /**
     * table name
     */
    protected $table = "posts";

    /**
     * allowed Field
     */
    protected $allowedFields = [
        'title',
        'content'
    ];
}

Tahap 2: Penulisan Kode & Konfigurasi

protected $table = "posts";

Tahap 3: Penulisan Kode & Konfigurasi

protected $allowedFields = [
        'title',
        'content'
];

Tahap 4: Penulisan Kode & Konfigurasi

<?php namespace App\Controllers;

use CodeIgniter\Controller;
use App\Models\PostModel;

class Post extends Controller
{
    /**
     * index function
     */
    public function index()
    {
        //model initialize
        $postModel = new PostModel();

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

        $data = array(
            'posts' => $postModel->paginate(2, 'post'),
            'pager' => $postModel->pager
        );

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