on the form processing page:
<?
if ($dropdown == 'option1') {
header ("location:http://www.whatever.com/option1.html");
}
if ($dropdown == 'option2') {
header ("location:http://www.whatever.com/option2.html");
}
?>
or you could simply put the content of both option pages in one single page and do:
<?
if ($dropdown == 'option1') {
// echo option1 stuff
}
if ($dropdown == 'option2') {
// echo option2 stuff
}
?>
this would be faster, the header() function slows thing down a bit
