Hi Artisan,

In this Article I will share something new about how actually work a comment system with laravel 8. I will create a custom comment system in laravel 8. so how to integrate custom nested comments using relationship in laravel 8.

First of all i will exaplain previous example how to create simple authentication using laravel-ui you will learn this first follow this article laravel-8-authentication-tutorial

So, in this example I will create two tables for one is posts and another is comments using the migration command.

Here,i will give you a simple and easy example how to use implement comment system in laravel 8 in laravel simply follow my all steps.

Step 1 : Install Laravel App

In this step, You can install laravel fresh app. So open the terminal and put the bellow command.

composer create-project --prefer-dist laravel/laravel commentSystem

Step 2 : Setup Database Configuration

DB_CONNECTION=mysql
DB_HOST=127.0.0.1
DB_PORT=3306
DB_DATABASE=Enter_Your_Database_Name
DB_USERNAME=Enter_Your_Database_Username
DB_PASSWORD=Enter_Your_Database_Password

Step 3 : Create Post and Comment Table

In this third step we have to integrate two tables using create migration for "posts" and "comments" table.

Path : /database/migrations/2021_09_20_130819_create_posts_comments_table.php

<?php

use Illuminate\Database\Migrations\Migration;
use Illuminate\Database\Schema\Blueprint;
use Illuminate\Support\Facades\Schema;

class CreatePostsCommentsTable extends Migration
{
    /**
     * Run the migrations.
     *
     * @return void
     */
    public function up()
    {
        Schema::create('posts', function (Blueprint $table) {
            $table->increments('id');
            $table->string('title');
            $table->text('body');
            $table->timestamps();
            $table->softDeletes();
        });

        Schema::create('comments', function (Blueprint $table) {
            $table->increments('id');
            $table->integer('user_id')->unsigned();
            $table->integer('post_id')->unsigned();
            $table->integer('parent_id')->unsigned()->nullable();
            $table->text('body');
            $table->timestamps();
            $table->softDeletes();
        });
    }

    /**
     * Reverse the migrations.
     *
     * @return void
     */
    public function down()
    {
        Schema::dropIfExists('posts');
        Schema::dropIfExists('comments');
    }
}

Now we need to run migration be bellow command:

php artisan migrate

Step 4 : Create Auth using scaffold

Now, in this step, we will create auth scaffold command to create login, register and dashboard. so run following commands:

composer require laravel/ui

Using Bootstrap:

php artisan ui bootstrap --auth

Step 5 : Create Model

In this step i will create a Post model using following command.

php artisan make:model Post

<?php

namespace App\Models;

use Illuminate\Database\Eloquent\Factories\HasFactory;
use Illuminate\Database\Eloquent\Model;
use Illuminate\Database\Eloquent\SoftDeletes;

class Post extends Model
{
    use HasFactory, SoftDeletes;

    protected $dates = ['deleted_at'];
    /**
     * The attributes that are mass assignable.
     *
     * @var array
     */
    protected $fillable = ['title', 'body'];

    /**
     * Write Your Code..
     *
     * @return string
    */
    public function comments()
    {
        return $this->hasMany(Comment::class)->whereNull('parent_id');
    }
}

Run bellow command for Comment model:

php artisan make:model Comment

<?php

namespace App\Models;

use Illuminate\Database\Eloquent\Factories\HasFactory;
use Illuminate\Database\Eloquent\Model;
use Illuminate\Database\Eloquent\SoftDeletes;

class Comment extends Model
{
    use HasFactory, SoftDeletes;

    protected $dates = ['deleted_at'];

    /**
     * The attributes that are mass assignable.
     *
     * @var array
     */
    protected $fillable = ['user_id', 'post_id', 'parent_id', 'body'];

    /**
     * Write Your Code..
     *
     * @return string
    */
    public function user()
    {
        return $this->belongsTo(User::class);
    }

    /**
     * Write Your Code..
     *
     * @return string
    */
    public function replies()
    {
        return $this->hasMany(Comment::class, 'parent_id');
    }
}

Step 6 : Create Route

now, we require to create a route for HomeController in laravel application. so open your "routes/web.php" file and add the following route.

<?php

use Illuminate\Support\Facades\Route;
use App\Http\Controllers\PostController;
use App\Http\Controllers\CommentController;

/*
|--------------------------------------------------------------------------
| Web Routes
|--------------------------------------------------------------------------
|
| Here is where you can register web routes for your application. These
| routes are loaded by the RouteServiceProvider within a group which
| contains the "web" middleware group. Now create something great!
|
*/

Route::resource('posts', PostController::class);
Route::post('comments', [CommentController::class, 'store'])->name('comments.store');

Step 7 : Create Controller

php artisan make:controller PostController

<?php

namespace App\Http\Controllers;

use Illuminate\Http\Request;
use App\Models\Post;
use App\Models\Comment;

class PostController extends Controller
{
    /**
     * Write Your Code..
     *
     * @return string
    */
    public function index()
    {
        $posts = Post::get();

        return view('post.index',compact('posts'));

    }

    /**
     * Write Your Code..
     *
     * @return string
    */
    public function create()
    {
        return view('post.create');
    }

    /**
     * Write Your Code..
     *
     * @return string
    */
    public function store(Request $request)
    {
        $input = $request->all();
        $request->validate([
            'title' => 'required',
            'body' => 'required',
        ]);

        Post::create($input);

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

    /**
     * Write Your Code..
     *
     * @return string
    */
    public function show($id)
    {
        $post = Post::find($id);

        return view('post.show',compact('post'));
    }

}

Create CommentController using bellow command:

php artisan make:controller CommentController

<?php

namespace App\Http\Controllers;

use Illuminate\Http\Request;
use App\Models\Comment;

class CommentController extends Controller
{
    /**
     * Write Your Code..
     *
     * @return string
    */
    public function store(Request $request)
    {
        $input = $request->all();

        $request->validate([
            'body'=>'required',
        ]);

        $input['user_id'] = auth()->user()->id;

        Comment::create($input);

        return back();
    }
}

Step 8 : Create Blade File

In this step we have to create a blade file. So finally you have to create the following file and put bellow code:

• index.blade.php

• create.blade.php

• show.blade.php

• commentsDisplay.blade.php

Path : /resources/views/post/index.blade.php
