Paginanummering
Ik heb onderstaande code van PHP Hulp en geimplementeerd op mijn site.
Werkt prima, op één ding na.
Hij begint de pagina nummering met '0' i.p.v. '1'...
Kan iemand mij helpden en vertellen waar het 'fout' gaat ?

Alvast bedankt voor de reacties.
Bedankt voor je snelle reactie.
Dit zorgt er in ieder geval voor dat ik geen '0' pagina als link zie. Echter lost dit mijn probleem niet op.
Feitelijk komt het hier op neer dat de pagina telling begint op pagina '0' en niet op pagina '1'. De linkjes echter, beginnen bij pagina '1' en daardoor vallen de eerste records uit de Db weg. Als je op de 'Eerste pagina' link klikt en kijkt naar de link, dan zie je ook dat er 'currentpage=0' staat, welke feitelijk pagina '0' oproept. Deze link moet dus eigenlijk ook op de pagina 1 link komen.
Volgens mij doet het probleem zich ook alleen voor bij pagina 1 ...
Raar is ook dat als je de pagina de eerste keer oproept, het wel klopt. Zodra je naar een andere pagina gaat en weer terug naar '1', het probleem zich voordoet.
Toevoeging op 25/10/2010 13:34:57:
en wat me net pas opvalt, is dat de laatste pagina hetzelfde records heeft als de eerste. Dus pagina 0 heeft dezelfde records als de laatste pagina ...
Hieronder de juiste code :
