plaatst hem in het juiste veld
maar als je klikt past hij hen niet aan

<?
$doeda = mysql_query('SELECT id FROM databasetabel WHERE weetikveelwat="'.$_GET['id'].'"');
mysql_result($doeda,0,"id");
?>
$doeda = mysql_query('SELECT id FROM databasetabel WHERE weetikveelwat="'.$_GET['id'].'"');
mysql_result($doeda,0,"id");
?>
en verander if($_post... ) in
