public function store(Request $request)  
{  
    $validatedData = $request->validate([  
        'name' => 'required|max:255',  
        'email' => 'required|email|unique:users|max:255',  
        'password' => 'required|min:8',  
    ]);  
  
    // Process the validated data  
    $user = User::create([  
        'name' => $validatedData['name'],  
        'email' => $validatedData['email'],  
        'password' => Hash::make($validatedData['password']),  
    ]);  
  
    // Redirect to a success page or perform other actions  
    return redirect()->route('users.index')->with('success', 'User created successfully.');  
}

<!-- Display validation errors -->  
@if($errors->any())  
    <div class="alert alert-danger">  
        <ul>  
            @foreach($errors->all() as $error)  
                <li>{{ $error }}</li>  
            @endforeach  
        </ul>  
    </div>  
@endif  
  
<!-- Create user form -->  
<form method="POST" action="{{ route('users.store') }}">  
    @csrf  
    <input type="text" name="name" placeholder="Name" value="{{ old('name') }}">  
    <input type="email" name="email" placeholder="Email" value="{{ old('email') }}">  
    <input type="password" name="password" placeholder="Password">  
    <button type="submit">Create User</button>  
</form>  

Ing kode ing ndhuwur, kita mriksa yen ana validation kesalahan lan nampilake ing kothak tandha. Fungsi kasebut old() digunakake kanggo ngisi maneh kolom formulir kanthi nilai sing wis dilebokake sadurunge yen ana validation kesalahan.

Kanthi nderek conto iki, sampeyan bisa validasi lan ngolah data input saka formulir nggunakake validation fitur ing Laravel. Iki mesthekake yen data kasebut cocog karo aturan sing wis ditemtokake lan mbantu njaga integritas data ing aplikasi sampeyan.
