Build a Complete Blog System in Laravel 12 (Step-by-Step Guide 2026)

Laravel 12 Blog System Tutorial: In this guide, we will build a complete blog system from scratch using Laravel 12. This project includes CRUD operations, image upload, and a simple admin panel.

This type of project is widely used in real-world applications such as CMS, news websites, and personal blogs.

Step 1. Install Laravel 12

composer create-project laravel/laravel blog-system
cd blog-system

Step 2. Setup Database

DB_DATABASE=blog_system
DB_USERNAME=root
DB_PASSWORD=

php artisan migrate

Step 3. Create Model & Migration

php artisan make:model Post -m

Schema::create('posts', function (Blueprint $table) {
    $table->id();
    $table->string('title');
    $table->string('slug')->unique();
    $table->text('description');
    $table->string('image')->nullable();
    $table->timestamps();
});

php artisan migrate

Step 4. Create Controller

php artisan make:controller PostController

class PostController extends Controller
{
    public function index() {
        return view('posts.index', ['posts' => Post::latest()->get()]);
    }

    public function create() {
        return view('posts.create');
    }

    public function store(Request $request) {
        $data = $request->validate([
            'title' => 'required',
            'description' => 'required',
            'image' => 'image|mimes:jpg,png,jpeg|max:2048'
        ]);

        if ($request->hasFile('image')) {
            $data['image'] = $request->file('image')->store('posts', 'public');
        }

        $data['slug'] = \Str::slug($request->title);

        Post::create($data);

        return redirect()->route('posts.index');
    }

    public function edit(Post $post) {
        return view('posts.edit', compact('post'));
    }

    public function update(Request $request, Post $post) {
        $post->update($request->all());
        return redirect()->route('posts.index');
    }

    public function destroy(Post $post) {
        $post->delete();
        return back();
    }
}

Step 5. Add Fillable

protected $fillable = ['title', 'slug', 'description', 'image'];

Step 6. Create Routes

use App\Http\Controllers\PostController;

Route::resource('posts', PostController::class);

Step 7. Create Blade Views

Create simple views:

• posts/index.blade.php
• posts/create.blade.php
• posts/edit.blade.php

Example form:

<form method="POST" enctype="multipart/form-data">
@csrf
<input type="text" name="title">
<textarea name="description"></textarea>
<input type="file" name="image">
<button type="submit">Save</button>
</form>

Conclusion: You have successfully built a complete blog system in Laravel 12 with CRUD functionality, image upload, and admin structure. This is a real-world project that helps you understand Laravel deeply.
