We will implement form validation using server side. Form data we will post via Ajax. In the request from client side, we will do request to server and validate form from server.

Let’s get started.

Laravel Installation

We will create laravel project using composer. So, please make sure your system should have composer installed. If not, may be this article will help you to Install composer in system.

Here is the command to create a laravel project-

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

To start the development server of Laravel –

php artisan serve


Assuming laravel already installed inside your system.

Create Routes

Open web.php from /routes folder and add these routes into it.

# Add this to header
use App\Http\Controllers\AjaxController;
use App\Http\Controllers\HomeController;

Route::get('add-form', [HomeController::class, 'addForm']);
Route::post('submit-form', [AjaxController::class, 'submitForm'])->name('add.form');

Create Controller

Open project into terminal and type these artisan command into it to create controllers.

$ php artisan make:controller HomeController

$ php artisan make:controller AjaxController

These commands will create HomeController.php and AjaxController.php files at /app/Http/Controllers folder.

HomeController will render form and AjaxController will process ajax request.

Open HomeController.php and write this code into it.


namespace App\Http\Controllers;

use Illuminate\Http\Request;

class HomeController extends Controller
    public function addForm()
        return view('add-form');

Open AjaxController.php and write this code into it.


namespace App\Http\Controllers;

use Illuminate\Http\Request;
use Validator;

class AjaxController extends Controller
    public function submitForm(Request $request)
        $validator = Validator::make($request->all(), [
            'first_name' => 'required',
            'last_name' => 'required',
            'email' => 'required|email'

        if ($validator->passes()) {
            return response()->json(['success' => 'Added new records.']);

        return response()->json(['error' => $validator->errors()->all()]);
