Laravel is currently one of the most popular PHP development frameworks. Its powerful and flexible features provide web developers with powerful development tools and APIs. In Laravel, form registration is a very common feature. Today we will learn how to use Laravel to implement form registration.

First, we need to create a route in Laravel to handle form submission and display the form page. We can add the following code in the routes/web.php file:

Route::get('/register', 'AuthRegisterController@showRegistrationForm')->name('register');
Route::post('/register', 'AuthRegisterController@register')->name('register');

Here, we define two routes, one is the GET request route, used to display the registration form page, The other is POST request routing, which is used to handle form submission data. We also named these two routes register.

Next, we need to define a controller to process and render the form page. We can use the following command to generate a controller:

php artisan make:controller AuthRegisterController

Then, we need to Write the method to process the form and render the form. The code is as follows:

namespace AppHttpControllersAuth;

use AppHttpControllersController;
use IlluminateFoundationAuthRegistersUsers;
use IlluminateSupportFacadesValidator;
use IlluminateHttpRequest;

class RegisterController extends Controller
{
    use RegistersUsers;

    protected $redirectTo = '/home';

    public function __construct()
    {
        $this->middleware('guest');
    }

    public function showRegistrationForm()
    {
        return view('auth.register');
    }

    public function register(Request $request)
    {
        $this->validator($request->all())->validate();

        $user = $this->create($request->all());

        $this->guard()->login($user);

        return redirect($this->redirectTo);
    }

    protected function validator(array $data)
    {
        return Validator::make($data, [
            'name' => ['required', 'string', 'max:255'],
            'email' => ['required', 'string', 'email', 'max:255', 'unique:users'],
            'password' => ['required', 'string', 'min:8', 'confirmed'],
        ]);
    }

    protected function create(array $data)
    {
        return User::create([
            'name' => $data['name'],
            'email' => $data['email'],
            'password' => Hash::make($data['password']),
        ]);
    }
}

Here, we use Laravel’s built-in RegistersUsers trait to provide the registered user function, which contains some common methods, Such as validator() method and create() method. These methods are used to validate form data and create new users respectively.

In the showRegistrationForm() method, we return a template view that contains our form content. In the register() method, we first use the validator() method to verify the form data. If the verification passes, we use the create() method to create New user and use the guard() method to log in to the user.

Finally, we need to create a form view to present the user registration form. We can add the following content in the resources/views/auth/register.blade.php file:

<div class="container">
    <div class="row justify-content-center">
        <div class="col-md-8">
            <div class="card">
                <div class="card-header">Register</div>

                <div class="card-body">
                    <form method="POST" action="{{ route('register') }}">
                        @csrf

                        <div class="form-group row">
                            <label for="name" class="col-md-4 col-form-label text-md-right">{{ __('Name') }}</label>

                            <div class="col-md-6">
                                <input id="name" type="text" class="form-control @error('name') is-invalid @enderror" name="name" value="{{ old('name') }}" required autocomplete="name" autofocus>

                                @error('name')
                                    <span class="invalid-feedback" role="alert">
                                        <strong>{{ $message }}</strong>
                                    </span>
                                @enderror
                            </div>
                        </div>

                        <div class="form-group row">
                            <label for="email" class="col-md-4 col-form-label text-md-right">{{ __('E-Mail Address') }}</label>

                            <div class="col-md-6">
                                <input id="email" type="email" class="form-control @error('email') is-invalid @enderror" name="email" value="{{ old('email') }}" required autocomplete="email">

                                @error('email')
                                    <span class="invalid-feedback" role="alert">
                                        <strong>{{ $message }}</strong>
                                    </span>
                                @enderror
                            </div>
                        </div>

                        <div class="form-group row">
                            <label for="password" class="col-md-4 col-form-label text-md-right">{{ __('Password') }}</label>

                            <div class="col-md-6">
                                <input id="password" type="password" class="form-control @error('password') is-invalid @enderror" name="password" required autocomplete="new-password">

                                @error('password')
                                    <span class="invalid-feedback" role="alert">

                                    </span>

                        <div class="form-group row">
                            <label for="password-confirm" class="col-md-4 col-form-label text-md-right">{{ __('Confirm Password') }}</label>

                            <div class="col-md-6">
                                <input id="password-confirm" type="password" class="form-control" name="password_confirmation" required autocomplete="new-password">
                            </div>
                        </div>

                        <div class="form-group row mb-0">
                            <div class="col-md-6 offset-md-4">
                                <button type="submit" class="btn btn-primary">
                                    {{ __('Register') }}
                                </button>
                            </div>
                        </div>
                    </form>
                </div>
            </div>
        </div>
    </div>
</div>

Here, we use the Bootstrap framework to beautify the form style. Among them, we used the @csrf directive to generate a hidden CSRF token input field, and also specified the registration route in the action attribute of the form tag. .

At this point, Laravel form registration is complete. We can use the php artisan serve command to start the local development server and visit http://localhost:8000/register to view the registration form page. When we fill in the correct form data and submit the form, the system registers the new user and logs them in automatically.

In short, it is so simple to implement form registration with Laravel. Laravel provides many built-in functions and tools to help us implement a variety of common and complex web applications. If you are good at using these functions and tools, you can quickly build efficient, stable, and easy-to-maintain web applications.
