Step 1: Install Laravel 9
This step will not needed; however, if we have not created the laravel app, then you may go ahead and then execute the below command:
composer create-project laravel/laravel example-app
Step 2: Create Controller
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.
app/Http/Controllers/FormController.php
<?php
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.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
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.
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 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:
resources/views/createUser.blade.php
<!DOCTYPE html>
<html>
<head>

@if(Session::has('success'))
<div class="alert alert-success">

@endif
<!-- Way 1: Display All Error Messages -->
@if ($errors->any())
<div class="alert alert-danger">

@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"

@endif
</div>
<div class="mb-3">
<label class="form-label" for="inputEmail">Email:</label>
<input

id="inputEmail"
class="form-control @error('email') is-invalid @enderror"
placeholder="Email">
@error('email')
<span class="text-danger">{{ $message }}</span>
@endif
</div>
<div class="mb-3">
<button class="btn btn-success btn-submit">Submit</button>
</div>
</form>
</div>
