Als de TS nou gewoon dat ene stukje relevante code post kunnen we hem helpen.

Ik ga geen 200 regels doorspitten op zoek naar iets wat jij wellicht zelf ook kan zien....
Wat wilde je ook al weer? Jezelf admin maken?

ik denk niet dat je dit zelf hebt gemaakt. even een tip hoor... antwoorden krijgen en kopieeren maakt je geen php programmeur, dat moet je zelf leren, ik heb al eerder een link gegeven hoe je simpel kan beginnen. succes

als je dit als OOP wilt gaan doen zou je sowieso een PERSON class o.i.d. moeten hebben. waar de algemene dingen in komen en vervolgens iets van ADMIN class en een USER class die allebei de PERSON class extenden beide met hun eigen rechten etc.. probeer het is eerst met normale php en zonder kopieren plakken. eventueel de basis van php leren en dan beginnen met simpele projectjes ...
totaal geen kennis van php maar ook niet de moeite doen om het te leren
Als je toch iets wilt maken als registreren in OOP, maak je beter een UserMapper en daarin een create() functie ofzo.
Waarom verbind je trouwens bij iedere functie met MySQL?
