Avatar van Tuinstoel PHP expert Setcookie("gestemd", "ja", Time()+25);

voor maar 25 seconden? http://www.php.net/setcookie voor wat meer informatie erover.

php code - Bekijk de code zonder highlighting - Klap code in 
  1. <?
  2. setcookie("gestemd","ja",time()+3600*24*7); // zet een cookie voor een week
  3. ?>
