Now in this step, i will create the new FormController for the adding form validation. Now In this controller i will add two method call create() and store(). So let’s create the new controller by using the following command.

php artisan make:controller FormController

Next, let’s need to update the following code to that file.


namespace App\Http\Controllers;
use Illuminate\Http\Request;
use App\Models\User;
class FormController 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(Request $request)
        $validatedData = $request->validate([
                'name' => 'required',
                'password' => 'required|min:5',
                'email' => 'required|email|unique:users'
            ], [
                'name.required' => 'Name field is required.',
                'password.required' => 'Password field is required.',
                'email.required' => 'Email field is required.',
                '' => 'Email field must be email address.'
        $validatedData['password'] = bcrypt($validatedData['password']);
        $user = User::create($validatedData);
        return back()->with('success', 'User created successfully.');
Step 3: Create Routes

Now need to open routes/web.php file and need to add the routes to manage GET and the POST requests for call the view and also adding form validation.


use Illuminate\Support\Facades\Route;
use App\Http\Controllers\FormController;
| 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::get('user/create', [ FormController::class, 'create' ]);
Route::post('user/create', [ FormController::class, 'store' ]);
Step 4: Create Blade File

Now here i will create the createUser.blade.php file and here i will create the bootstrap simple form also with error validation message.

So, let’s create the following file:


<!DOCTYPE html>
    <title>Laravel 9 Form Validation Example -</title>
    <meta charset="utf-8">
    <meta http-equiv="X-UA-Compatible" content="IE=edge">
    <meta name="viewport" content="width=device-width, initial-scale=1">
    <link href="" rel="stylesheet">
    <div class="container">
        <h1>Laravel 9 Form Validation Example -</h1>
        <div class="alert alert-success">
            {{ Session::get('success') }}
        <!-- Way 1: Display All Error Messages -->
        @if ($errors->any())
            <div class="alert alert-danger">
                <strong>Whoops!</strong> There were some problems with your input.<br><br>
                    @foreach ($errors->all() as $error)
                        <li>{{ $error }}</li>
        <form method="POST" action="{{ url('user/create') }}">
            {{ csrf_field() }}
            <div class="mb-3">
                <label class="form-label" for="inputName">Name:</label>
                    class="form-control @error('name') is-invalid @enderror" 
                <!-- Way 2: Display Error Message -->
                    <span class="text-danger">{{ $message }}</span>
            <div class="mb-3">
                <label class="form-label" for="inputPassword">Password:</label>
                    class="form-control @error('password') is-invalid @enderror" 
                <!-- Way 3: Display Error Message -->
                @if ($errors->has('password'))
                    <span class="text-danger">{{ $errors->first('password') }}</span>
            <div class="mb-3">
                <label class="form-label" for="inputEmail">Email:</label>
                    class="form-control @error('email') is-invalid @enderror" 
                    <span class="text-danger">{{ $message }}</span>
            <div class="mb-3">
                <button class="btn btn-success btn-submit">Submit</button>
