Undefined index when performing query
  • JeanAlesiJeanAlesi
    What does the error "Fuel\Core\PhpErrorException [ Notice ]:
    Undefined index:" mean?

    It happened when running this function:

    $groups = Model_Tmgroup::query()
                        ->where('owner_id', '=', $user_id)
                        ->related('tmfriends')
                        ->get();

    if owner_id in tmfriends relation, you must use


    $groups = Model_Tmgroup::query()
                        ->related('tmfriends')
                        ->where('tmfriends.owner_id', '=', $user_id)
                        ->get();

    PHPErrorException's are standard PHP errors that are wrapped in an exception so they can be caught and handled. So this is a standard PHP notice.

    And it should tell you exactly where in the code it happens, in development mode exceptions are shown with a backtrace with code snippets.
