Recommended place in Laravel to alter form input

The recommended place to alter form input before storing it in the database is in the controller's store method. You can use Laravel's built-in validation and then modify the input before saving it to the database. Here's an example:

public function store(Request $request)
{
    $validatedData = $request->validate([
        'name' => 'required|string|max:255',
        'email' => 'required|string|email|max:255|unique:users',
        'password' => 'required|string|min:8|confirmed',
    ]);

    // Modify the input before saving it to the database
    $validatedData['name'] = strtolower($validatedData['name']);

    $user = User::create($validatedData);

    return redirect('/home');
}

In this example, we're using Laravel's validation to validate the input. After validation, we're modifying the name input to lowercase before saving it to the database.
