Ik heb geen flauw idee hoe ik het moet oplossen.
Mijn database naam is loginsystem
En dit is ook iets maar misschien kunnen jullie me uitleggen wat het doet ?

En nu over het script.
Het is mysql_select_db en niet mysql_select_database (regel 21)

Dat is nu je config bestand. Kijk maar eens op php.net naar define
Maar dan nu de vraag, als je niks van PHP weet, waarom start je dan met zo een moeilijk script? Je kan beter zelf een script bouwen en exact weten wat het doet dan een script van het internet plukken.
