Teknik Safe Deletion & Pembersihan Storage Otomatis Di Laravel 9 — Part 6

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;

use App\Models\Post;
use Illuminate\Http\Request;
use Illuminate\Support\Facades\Storage;

class PostController extends Controller
{    
    /**
     * index
     *
     * @return void
     */
    public function index()
    {
        //get posts
        $posts = Post::latest()->paginate(5);

        //render view with posts
        return view('posts.index', compact('posts'));
    }
    
    /**
     * create
     *
     * @return void
     */
    public function create()
    {
        return view('posts.create');
    }

    /**
     * store
     *
     * @param Request $request
     * @return void
     */
    public function store(Request $request)
    {
        //validate form
        $this->validate($request, [
            'image'     => 'required|image|mimes:jpeg,png,jpg,gif,svg|max:2048',
            'title'     => 'required|min:5',
            'content'   => 'required|min:10'
        ]);

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

        //create post
        Post::create([
            'image'     => $image->hashName(),
            'title'     => $request->title,
            'content'   => $request->content
        ]);

        //redirect to index
        return redirect()->route('posts.index')->with(['success' => 'Data Berhasil Disimpan!']);
    }
    
    /**
     * edit
     *
     * @param  mixed $post
     * @return void
     */
    public function edit(Post $post)
    {
        return view('posts.edit', compact('post'));
    }
    
    /**
     * update
     *
     * @param  mixed $request
     * @param  mixed $post
     * @return void
     */
    public function update(Request $request, Post $post)
    {
        //validate form
        $this->validate($request, [
            'image'     => 'image|mimes:jpeg,png,jpg,gif,svg|max:2048',
            'title'     => 'required|min:5',
            'content'   => 'required|min:10'
        ]);

        //check if image is uploaded
        if ($request->hasFile('image')) {

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

            //delete old image
            Storage::delete('public/posts/'.$post->image);

            //update post with new image
            $post->update([
                'image'     => $image->hashName(),
                'title'     => $request->title,
                'content'   => $request->content
            ]);

        } else {

            //update post without image
            $post->update([
                'title'     => $request->title,
                'content'   => $request->content
            ]);
        }

        //redirect to index
        return redirect()->route('posts.index')->with(['success' => 'Data Berhasil Diubah!']);
    }
    
    /**
     * destroy
     *
     * @param  mixed $post
     * @return void
     */
    public function destroy(Post $post)
    {
        //delete image
        Storage::delete('public/posts/'. $post->image);

        //delete post
        $post->delete();

        //redirect to index
        return redirect()->route('posts.index')->with(['success' => 'Data Berhasil Dihapus!']);
    }
}

Tahap 2: Penulisan Kode & Konfigurasi

//delete image
Storage::delete('public/posts/'. $post->image);

Tahap 3: Penulisan Kode & Konfigurasi

//delete post
$post->delete();

Tahap 4: Penulisan Kode & Konfigurasi

//redirect to index
return redirect()->route('posts.index')->with(['success' => 'Data Berhasil Dihapus!']);

Kesimpulan

Dengan mengikuti langkah-langkah terstruktur di atas, implementasi modul Anda akan jauh lebih rapi, aman dari bug umum, serta siap diskalakan ke lingkungan produksi.
