Hulp met fout: Undefined Variable: _SESSION en Call To Undefined Method PDO::fetch()
Tijdens het volgen van een blog tutorial liep ik tegen een probleem aan. Vervolgens leek het of ik het probleem had opgelost door een paar aanpassingen te doen, maar helaas.. zonder resultaat.
Ik krijg na het inloggen als admin de fout: ]Undefined Variable: _SESSION en Call To Undefined Method PDO::fetch()
Het gaat om de code hieronder.
Alvast heel erg bedankt! :)

Engels is beter gangbaarder in de programmeerwereld.
