Laravel is a powerful PHP framework that comes with a built-in authentication system. However, in some cases, you may prefer to implement a login and registration system manually without relying on external libraries. In this tutorial, we’ll guide you through the process of creating a basic login and registration system in Laravel without using any library.
Prerequisites
Before we begin, make sure you have the following prerequisites:
- Laravel installed on your system
- Basic understanding of Laravel’s MVC structure
- Familiarity with PHP and web development concepts
Step 1: Set Up the Database
First, we need to create a database table to store user information. Follow these steps:
- Run the migration command to generate a migration file:
php artisan make:migration create_users_table 2. Open the generated migration file and define the structure of the users table. Include fields such as id, name, email, password, created_at, and updated_at.
3. Run the migration command to create the users table in the database:
php artisan migrateStep 2: Create the User Model
Next, we’ll create a User model to interact with the users table. Follow these steps:
- Run the command to generate a User model class:
php artisan make:model User2. Open the generated User model class and define the table name, fillable attributes, and any other required methods or relationships.
Step 3: Define Routes
In this step, we’ll define the routes for registration, login, and logout. Here’s an example:
Route::get('/register', 'AuthController@showRegistrationForm')->name('register');
Route::post('/register', 'AuthController@register');
Route::get('/login', 'AuthController@showLoginForm')->name('login');
Route::post('/login', 'AuthController@login');
Route::post('/logout', 'AuthController@logout')->name('logout');Step 4: Create the AuthController
Now, we’ll create an AuthController to handle user registration, login, and logout. Follow these steps:
- Run the command to generate a controller class:
php artisan make:controller AuthController2. Open the generated AuthController class and implement the necessary methods. Here’s an example:
use App\Models\User;
use Illuminate\Http\Request;
use Illuminate\Support\Facades\Hash;
class AuthController extends Controller
{
public function showRegistrationForm()
{
return view('register');
}
public function register(Request $request)
{
// Validation
$request->validate([
'name' => 'required',
'email' => 'required|email|unique:users',
'password' => 'required|min:6',
]);
// Create a new user
$user = new User();
$user->name = $request->input('name');
$user->email = $request->input('email');
$user->password = Hash::make($request->input('password'));
$user->save();
// Redirect to login page with success message
return redirect('/login')->with('success', 'Registration successful!');
}
public function showLoginForm()
{
return view('login');
}
public function login(Request $request)
{
$credentials = $request->validate([
'email' => 'required|email',
'password' => 'required',
]);
if (auth()->attempt($credentials)) {
// Authentication successful
return redirect('/home');
} else {
// Invalid credentials
return back()->withErrors(['email' => 'Invalid credentials']);
}
}
public function logout()
{
auth()->logout();
// You can customize this redirect based on your needs
return redirect('/login')->with('success', 'Logged out successfully!');
}
}Step 5: Create the Registration and Login Views
Now, we’ll create the blade templates for the registration and login forms. Here are examples of the register.blade.php and login.blade.php files:
register.blade.php
<!DOCTYPE html>
<html>
<head>
<title>Register</title>
</head>
<body>
<h2>Register</h2>
@if ($errors->any())
<div class="alert alert-danger">
<ul>
@foreach ($errors->all() as $error)
<li>{{ $error }}</li>
@endforeach
</ul>
</div>
@endif
@if (session('success'))
<div class="alert alert-success">
{{ session('success') }}
</div>
@endif
<form method="POST" action="{{ route('register') }}">
@csrf
<div>
<label for="name">Name</label>
<input type="text" id="name" name="name" value="{{ old('name') }}" required autofocus>
</div>
<div>
<label for="email">Email</label>
<input type="email" id="email" name="email" value="{{ old('email') }}" required>
</div>
<div>
<label for="password">Password</label>
<input type="password" id="password" name="password" required>
</div>
<div>
<label for="password_confirmation">Confirm Password</label>
<input type="password" id="password_confirmation" name="password_confirmation" required>
</div>
<button type="submit">Register</button>
</form>
</body>
</html>
login.blade.php
<!DOCTYPE html>
<html>
<head>
<title>Login</title>
</head>
<body>
<h2>Login</h2>
@if ($errors->any())
<div class="alert alert-danger">
<ul>
@foreach ($errors->all() as $error)
<li>{{ $error }}</li>
@endforeach
</ul>
</div>
@endif
<form method="POST" action="{{ route('login') }}">
@csrf
<div>
<label for="email">Email</label>
<input type="email" id="email" name="email" value="{{ old('email') }}" required autofocus>
</div>
<div>
<label for="password">Password</label>
<input type="password" id="password" name="password" required>
</div>
<button type="submit">Login</button>
</form>
</body>
</html>
Step 6: Protect Routes Requiring Authentication
If you have any routes that should only be accessible to authenticated users, protect them using the auth middleware. Here’s an example:
Route::get('/home', 'HomeController@index')->middleware('auth');This ensures that only logged-in users can access the /home route.
Conclusion
In this tutorial, we’ve shown you how to create a login and registration system in Laravel without using any external libraries. While this approach gives you complete control over the implementation, it’s important to note that Laravel provides a robust built-in authentication system and using a well-tested library is often recommended for security reasons and development efficiency.
