Hey Guys,

This tutorial will give you an example of laravel 10 form validation tutorial. you will learn laravel 10 form validation with error message. you can see form validation laravel 10. I would like to share with you simple form validation in laravel 10.

Laravel 10 provides a request object to add form validation using it. we will use request validate() for adding validation rules and custom messages. we will use the $errors variable to display error messages. I will show you a very simple step-by-step example of how to add form validation in the laravel 10 application.

so, let's see the below example for adding form validation.

Step for Laravel 10 Form Validation with Error Message

  • Step 1: Install Laravel 10
  • Step 2: Create Controller
  • Step 3: Create Routes
  • Step 4: Create Blade File
  • Run Laravel App

Step 1: Install Laravel 10

This step is not required; however, if you have not created the laravel app, then you may go ahead and execute the below command:

composer create-project laravel/laravel example-app

Step 2: Create Controller

In this step, we will create a new FormController for adding form validation. in this controller, we will add two method called create() and store(). so let's create a new controller by the following command.

php artisan make:controller FormController

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

app/Http/Controllers/FormController.php

<?php
    
namespace App\Http\Controllers;
    
use Illuminate\Http\Request;
use App\Models\User;
use Illuminate\View\View;
use Illuminate\Http\RedirectResponse;
   
class FormController extends Controller
{
    /**
     * Show the application dashboard.
     *
     * @return \Illuminate\Http\Response
     */
    public function create(): View
    {
        return view('createUser');
    }
        
    /**
     * Show the application dashboard.
     *
     * @return \Illuminate\Http\Response
     */
    public function store(Request $request): RedirectResponse
    {
    
        $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.email' => '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

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

routes/web.php

<?php
  
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 we will create createUser.blade.php file and here we will create bootstrap simple form with error validation message. So, let's create following file:

resources/views/createUser.blade.php

<!DOCTYPE html>
<html>
<head>
    <title>Laravel 10 Form Validation Example - ItSolutionStuff.com</title>
    <meta charset="utf-8">

        @if(Session::has('success'))
        <div class="alert alert-success">
            {{ Session::get('success') }}
            @php
                Session::forget('success');
            @endphp
        </div>
        @endif
    
        <!-- Way 1: Display All Error Messages -->
        @if ($errors->any())
            <div class="alert alert-danger">
                <strong>Whoops!</strong> There were some problems with your input.<br><br>
                <ul>
                    @foreach ($errors->all() as $error)
                        <li>{{ $error }}</li>
                    @endforeach
                </ul>
            </div>
        @endif
       
        <form method="POST" action="{{ url('user/create') }}">
      
            {{ csrf_field() }}
      
            <div class="mb-3">
                <label class="form-label" for="inputName">Name:</label>
                <input 
                    type="text" 
                    name="name" 
                    id="inputName"
                    class="form-control @error('name') is-invalid @enderror" 
                    placeholder="Name">
  
                <!-- Way 2: Display Error Message -->

                    <span class="text-danger">{{ $message }}</span>

                <!-- Way 3: Display Error Message -->
                @if ($errors->has('password'))
                    <span class="text-danger">{{ $errors->first('password') }}</span>
                @endif
