Contoh CRUD CodeIgniter 4 dan MySQL Lengkap

Membuat Migration Tabel Products

Buat migration:

php spark make:migration CreateProducts

Isi file migration yang terbentuk di app/Database/Migrations dengan struktur berikut:

<?php

namespace App\Database\Migrations;

use CodeIgniter\Database\Migration;

class CreateProducts extends Migration
{
    public function up(): void
    {
        $this->forge->addField([
            'id' => [
                'type' => 'INT', 'constraint' => 11,
                'unsigned' => true, 'auto_increment' => true,
            ],
            'sku' => ['type' => 'VARCHAR', 'constraint' => 40],
            'name' => ['type' => 'VARCHAR', 'constraint' => 150],
            'price' => ['type' => 'DECIMAL', 'constraint' => '12,2', 'default' => 0],
            'stock' => ['type' => 'INT', 'constraint' => 11, 'unsigned' => true, 'default' => 0],
            'description' => ['type' => 'TEXT', 'null' => true],
            'created_at' => ['type' => 'DATETIME', 'null' => true],
            'updated_at' => ['type' => 'DATETIME', 'null' => true],
        ]);

        $this->forge->addKey('id', true);
        $this->forge->addUniqueKey('sku');
        $this->forge->createTable('products');
    }

    public function down(): void
    {
        $this->forge->dropTable('products');
    }
}

Jalankan migration:

php spark migrate

Migration menyimpan perubahan struktur database sebagai kode dan menyediakan operasi rollback melalui method down().
