Filament: Login via url

To achieve login via a URL in a Laravel application using Filament, you can create a custom route that accepts the code from the URL, validates it, and logs the user in. Here’s a step-by-step solution:

1. Create a Route: Define a route in your web.php file that will handle the login via URL.

   // routes/web.php
   use App\Http\Controllers\Auth\LoginController;
   
   Route::get('/login/{code}', [LoginController::class, 'loginWithCode']);
   

2. Create a Controller Method: In your LoginController, create a method loginWithCode that will handle the login logic.

   // app/Http/Controllers/Auth/LoginController.php
   namespace App\Http\Controllers\Auth;
   
   use App\Http\Controllers\Controller;
   use Illuminate\Http\Request;
   use Illuminate\Support\Facades\Auth;
   use App\Models\User;
   
   class LoginController extends Controller
   {
       public function loginWithCode($code)
       {
           // Find the user by the code
           $user = User::where('login_code', $code)->first();
   
           if ($user) {
               // Log the user in
               Auth::login($user);
   
               // Redirect to the intended page or dashboard
               return redirect()->intended('/dashboard');
           }
   
           // If the code is invalid, redirect to the login page with an error
           return redirect('/login')->withErrors(['code' => 'Invalid login code.']);
       }
   }
   

3. Add a Login Code to Users: Ensure that your User model has a login_code field. You might need to add this field to your users table.

   // database/migrations/xxxx_xx_xx_xxxxxx_add_login_code_to_users_table.php
   use Illuminate\Database\Migrations\Migration;
   use Illuminate\Database\Schema\Blueprint;
   use Illuminate\Support\Facades\Schema;
   
   class AddLoginCodeToUsersTable extends Migration
   {
       public function up()
       {
           Schema::table('users', function (Blueprint $table) {
               $table->string('login_code')->nullable()->unique();
           });
       }
   
       public function down()
       {
           Schema::table('users', function (Blueprint $table) {
               $table->dropColumn('login_code');
           });
       }
   }
   

4. Generate Login Codes: You need a way to generate and assign login codes to users. This can be done when creating a user or through a separate process.

   // Example of generating a login code
   use Illuminate\Support\Str;
   
   $user->login_code = Str::random(10);
   $user->save();
   

5. Secure the Login Code: Ensure that the login code is secure and not easily guessable. Using Str::random(10) generates a random 10-character string which should be sufficiently secure for most applications.

By following these steps, you can bypass the traditional login form and allow users to log in directly via a URL containing a unique code.
