NIe wiem czemu nie łączy mi z baza danych oraz czemu wypisuje ze nie rozpoznaje zapytania query

SQLSTATE[28000] [1045] Access denied for user 'ODBC'@'localhost' (using password: NO)
Fatal error: Call to a member function query() on a non-object in C:\xampp\htdocs\pobieralnia\user\include\class_session.php on line 166


Dane do mysql dobre bo wcześniej się łączyłem i łączyło mi przez PDO
skoro select w pdo wywoluje sie za pomoca query. ?

Mam nadzieje ze to nie jest listing 1 do 1 z twojego pliku class_session.php bo jak tak to masz kilka błędów. Jak nie jest to zrób print_r($this->_db) na początku metody open, zobacz czy dane są prawidłowe i czy się w ogóle wyświetla. Jak nie to przerzuć łączenie z PDO do konstruktora klasy, bo pewnie nie wywołuje ci się metoda open.
