Question

I want that users can login with the registration number assigned to them or email. I have working api which only login users with email

public $successStatus = 200;

public function login(){ 
    if(Auth::attempt(['email' => request('email'), 'password' => request('password')])){ 
        $user = Auth::user(); 
        $success['token'] =  $user->createToken('MyApp')-> accessToken; 
        return response()->json(['success' => $success], $this-> successStatus); 
    } 
    else{ 
        return response()->json(['error'=>'Unauthorised'], 401); 
    } 
}

Answer 1

You can check the value of the email in your request parameter to determine if an email or number has been provided and then attempt to log in your user that way.

public function login()
{
  // determine if the value of the `email` field in the request
  // is a valid `email` or not
  $identity = filter_var(request('email'), FILTER_VALIDATE_EMAIL) ? 'email' : 'number';
  
  // use the value of $identity for specifying the field,
  // to compare against the value of the `email` in the request
  if (Auth::attempt([$identity => request('email'), 'password' => request('password']))) {
    $success['token'] =  $user->createToken('MyApp')-> accessToken; 
    return response()->json(['success' => $success], $this-> successStatus); 
  }

  return response()->json(['error'=>'Unauthorised'], 401);
}
