Hi Dev,

We will use How to create follow unfollow functionality in laravel 9?. This post will give you simple example of follow and unfollow using single button with jquery & ajax by laravel 9 example.

you will do the following things for laravel 9 follow and unfollow Code Example.

how to build follow unfollow system in laravel 9 example?

Just follow a few step and you will get layout like as bellow preview and also you can download script from bellow link.

Let us begin the tutorial by installing a new laravel application. if you have already created the project, then skip following step.

composer create-project laravel/laravel example-app

Now we need to install laravel-follow package for follow unfollow system. So Open your terminal and run the bellow command.

composer require overtrue/laravel-follow -vvv

Now open the config/app.php file and add service provider and alias.

'providers' => [

    Overtrue\LaravelFollow\FollowServiceProvider::class,

],

To publish the migrations file run bellow command

php artisan vendor:publish --provider='Overtrue\LaravelFollow\FollowServiceProvider' --tag="migrations"

As optional if you want to modify the default configuration, you can publish the configuration file:

php artisan vendor:publish --provider="Overtrue\LaravelFollow\FollowServiceProvider" --tag="config"

Then just migrate it by using the following command:

php artisan migrate

In this step, we require to create authentication of Laravel 9, so laravel provides an artisan command to create authentication that way we don't require to create a route and controller for login and registration. so run bellow command:

php artisan make:auth

In this step, we will create some dummy users for testing, so we will create dummy users using the formate factory. so run the below command:

php artisan tinker
factory(App\User::class, 100)->create();

here we need to update the User model. we need to use the CanLike trait in the User model. So let's update as bellow code.

namespace App;

use Illuminate\Notifications\Notifiable;
use Illuminate\Foundation\Auth\User as Authenticatable;
use Overtrue\LaravelFollow\Traits\CanFollow;
use Overtrue\LaravelFollow\Traits\CanBeFollowed;


class User extends Authenticatable
{
    use Notifiable, CanFollow, CanBeFollowed; //See we used CanFollow and CanBeFollowed Traits

    protected $fillable = [
        'name', 'email', 'password',
    ];

    protected $hidden = [
        'password', 'remember_token',
    ];
}

In this step, we will create routes for follow, unfollow system in Laravel. So we require to create the following route in the web.php file.

Route::get('users', 'HomeController@users')->name('users');
Route::get('user/{id}', 'HomeController@user')->name('user.view');
Route::post('follow', 'HomeController@follwUserRequest')->name('follow');

now in HomeController, we will add three new method users(), user() and ajaxRequest(). so let's see HomeController like as bellow:

namespace App\Http\Controllers;

use Illuminate\Http\Request;
use App\User;


class HomeController extends Controller
{
    
    public function __construct()
    {
        $this->middleware('auth');
    }

    public function index()
    {
        return view('home');
    }

    public function users()
    {
        $users = User::get();
        return view('users', compact('users'));
    }

    public function user($id)
    {
        $user = User::find($id);
        return view('usersView', compact('user'));
    }

    public function follwUserRequest(Request $request){


        $user = User::find($request->user_id);
        $response = auth()->user()->toggleFollow($user);


        return response()->json(['success'=>$response]);
    }
}

Now in this file, we will need to create userList.blade.php, users.blade.php, and usersView.blade.php files and custom.js file. So let's create both files.

@extends('layouts.app')

@section('content')
<script src="{{ asset('js/custom.js') }}" defer></script>
