mysql - 用户登录时如何更新 updated_at 列？

Question

我正在尝试将 updated_at 列更新为当前时间，每次用户登录时。

但我收到以下错误:

InvalidArgumentException A four digit year could not be found Data missing

PHP

$input = Input::all();
$remember = (Input::has('remember')) ? true : false;

$auth = Auth::attempt([
    'username' => $input['username'],
    'password' => $input['password'],
    'active' => 1
    ],$remember
);

if ($auth) 
{
    $user = Auth::user();
    $user->updated_at = DB::raw('NOW()');
    $user->save();

    if ($user->userType==1) 
    {
        return Redirect::intended('admin');
    }
    elseif ($user->userType==2)
    {
        return Redirect::intended('corporate');
    }
    elseif ($user->userType==3) 
    {
        return Redirect::intended('trainer');
    }
    elseif ($user->userType==4) 
    {
        return Redirect::intended('user');
    }
}

为此，您可以使用 Eloquent 方法 touch():

//instead of
$user->updated_at = DB::raw('NOW()');
$user->save();

// simply this:
$user->touch();
