How to update the updated_at column when the user logs in? - mysql

Question

I'm trying to update the updated_at column to the current time, each time a user logs in.
But I get the following error:
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');
}
}

Answer 1

You can use the Eloquent method touch() for this:
//instead of
$user->updated_at = DB::raw('NOW()');
$user->save();
// simply this:
$user->touch();

Answer 2

For one I would not use the updated_at column as that's the default timestamps name.
You would be better of with last_login
And just use the PHP date method.
$user->updated_at = date('Y-m-d G:i:s');
Hope this helps.

Answer 3

I think you're accidentally assigning a value instead of using array syntax. eg:
Model::create([
'key'='val'
]);
instead of:
Model::create([
'key'=>'val'
]);
