How to Validate Form in Laravel 11 Example
Hello developer, in this article we'll see how to validate forms in laravel 11. Form validation is a crucial aspect of web development, ensuring that the data entered by users meets the specified criteria before it's processed further.
Laravel 11, from setting up validation rules to displaying error messages and handling the validation logic in our controllers.
So, let's see Laravel 11 form validation and laravel 11 validation.
In this step, we'll install the laravel 11 application using the following composer command.
composer create-project laravel/laravel laravel-1-form-validation
Now, we'll create a UserController.php file using the following artisan command. and we'll validate inputs in the store() function.
php artisan make:controller UserController
app/Http/Controllers/UserController.php
<?php
namespace App\Http\Controllers;
use Illuminate\Http\Request;
use App\Models\User;
use Illuminate\View\View;
use Illuminate\Http\RedirectResponse;
class UserController extends Controller
{
/**
* Show the application dashboard.
*
* @return \Illuminate\Http\Response
*/
public function create(): View
{
return view('create');
}
/**
* 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.');
}
}
Then, we'll define routes on the web.php file. So, add the following code to this file.
routes/web.php
<?php
use Illuminate\Support\Facades\Route;
use App\Http\Controllers\UserController;
Route::get('users/create', [ UserController::class, 'create' ]);
Route::post('users/create', [ UserController::class, 'store' ])->name('users.store');
In this step, we'll create a blade file and add a simple form for validation in laravel 11. So, add the following code to this file.
resources/views/create.blade.php

</div>
</form>
