Je kan een sessie setten met informatie over de post. Als het de zelfde post (checken op inhoud) is, zeg je dat het een dubbelpost is..
Aanvullend bericht:
En eventueel kan je ook nog een redirect maken, zodat bij het refreshen die melding van opnieuw verzenden niet komt.

**M van Eijken** · 01-05-2009, 22:41

kan iemand die beveiliging voor mij plaatsen

**Jesper van E.** · 01-05-2009, 23:16

kan iemand die beveiliging voor mij plaatsen

Probeer eerst zelf eens wat zou ik zeggen...

**M van Eijken** · 13-05-2009, 20:32

kan iemand hier wat mee

**David C.** · 13-05-2009, 20:33

Wat een code is me dat..

**M van Eijken** · 13-05-2009, 20:34

ja mooi he

**Eric Bruggema** · 13-05-2009, 20:40

Doe eens het volgende maak een MD5 van de tekst, sla deze op in een sessie alvorens je het in de database zet. Bij refresh (of post) controleer of deze sessie bestaat en zo ja of deze gelijk is aan de huidige sessie... is dat niet het geval = posten, wel het geval = niet posten en fout melding geven. Ander idee is laatste post checken in de database :)

Oh en je code is zo lek als een mandje, als ik wil is je website binnen een halve seconde plat en is je database geheel leeg..

Controleer dan ook de inputs!!! (eerste regel bij verantwoord scripten :D)
