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\Http\Controllers;

//import model product
use App\Models\Product; 

//import return type View
use Illuminate\View\View;

//import return type redirectResponse
use Illuminate\Http\RedirectResponse;

//import Http Request
use Illuminate\Http\Request;

class ProductController extends Controller
{
    /**
     * index
     *
     * @return void
     */
    public function index() : View
    {
        //get all products
        $products = Product::latest()->paginate(10);

        //render view with products
        return view('products.index', compact('products'));
    }

    /**
     * create
     *
     * @return View
     */
    public function create(): View
    {
        return view('products.create');
    }

    /**
     * store
     *
     * @param  mixed $request
     * @return RedirectResponse
     */
    public function store(Request $request): RedirectResponse
    {
        //validate form
        $request->validate([
            'image'         => 'required|image|mimes:jpeg,jpg,png|max:2048',
            'title'         => 'required|min:5',
            'description'   => 'required|min:10',
            'price'         => 'required|numeric',
            'stock'         => 'required|numeric'
        ]);

        //upload image
        $image = $request->file('image');
        $image->storeAs('public/products', $image->hashName());

        //create product
        Product::create([
            'image'         => $image->hashName(),
            'title'         => $request->title,
            'description'   => $request->description,
            'price'         => $request->price,
            'stock'         => $request->stock
        ]);

        //redirect to index
        return redirect()->route('products.index')->with(['success' => 'Data Berhasil Disimpan!']);
    }
    
    /**
     * show
     *
     * @param  mixed $id
     * @return View
     */
    public function show(string $id): View
    {
        //get product by ID
        $product = Product::findOrFail($id);

        //render view with product
        return view('products.show', compact('product'));
    }
}

Tahap 2: Penulisan Kode & Konfigurasi

public function show(string $id): View
{

	//...
	
}

Tahap 3: Penulisan Kode & Konfigurasi

//get product by ID
$product = Product::findOrFail($id);

Tahap 4: Penulisan Kode & Konfigurasi

//render view with product
return view('products.show', compact('product'));

Tahap 5: Penulisan Kode & Konfigurasi

    └── products
        ├── index.blade.php
        ├── create.blade.php
        ├── show.blade.php  <-- (File yang akan kita buat)
