We will look at example of handle request validation in laravel. I’m going to show you about validation request rules class with laravel 6, laravel 7, laravel 8, laravel 9, laravel 10 and laravel 11 app.

In this tutorial, i will show you how smart way we can handle form request validation in laravel. we will create new request class for adding validation for our form in laravel. it's best way for developing to create new class for request and handle it.

So, here in this tutorial, you have to follow few step to create form validation with request class in laravel. here we will create StoreUser request class and declare rules here.

Let's follow bellow step and will get layout as like bellow:

Preview:

Step 1: Create Routes

Here we are learning simple and easy example of validation in laravel 7 so just add following both route in your web.php file.

routes/web.php

Route::get('user/create', 'HomeController@create');
Route::post('user/create', 'HomeController@store');

Step 2: Create Request Class

Here, we will create request class where we will define validation rules. so let's create "StoreUser" class using bellow command:

php artisan make:request StoreUser

now, we will update rules as bellow:

app/Http/Requests/StoreUser.php

<?php
  
namespace App\Http\Requests;
  
use Illuminate\Foundation\Http\FormRequest;
  
class StoreUser extends FormRequest
{
    /**
     * Determine if the user is authorized to make this request.
     *
     * @return bool
     */
    public function authorize()
    {
        return true;
    }
  
    /** 
     * Get the validation rules that apply to the request.
     *
     * @return array
     */
    public function rules()
    {
        return [
                'name' => 'required',
                'username' => 'required|min:8',
                'email' => 'required|email|unique:users'
            ];
    }
}

Step 3: Create Controller

Now we will add two controller method, one will just display blade file with get request, and another for post request with validation, we will use StoreUser class for validation, i write validation for that, so simply add both following method on it.

app/Http/Controllers/HomeController.php

<?php
    
namespace App\Http\Controllers;
    
use Illuminate\Http\Request;
use App\User;
use App\Http\Requests\StoreUser;
    
class HomeController extends Controller
{
    /**
     * Show the application dashboard.
     *
     * @return \Illuminate\Http\Response
     */
    public function create()
    {
        return view('createUser');
    }
    
    /**
     * Show the application dashboard.
     *
     * @return \Illuminate\Http\Response
     */
    public function store(StoreUser $request)
    {
        $input = $request->all();
        $user = User::create($input);
      
        return back()->with('success', 'User created successfully.');
    }
}
