You can get to it via $_POST['action'].
Look for the position of the '#' using strpos(), then substr() the
desired part from the total string.
e.g.
<?PHP
$bookmark=false;
if (isset($_POST['action']){
if ($poundpos=strpos($_POST['action'],'#')!=false){
$bookmark=substr($_POST['action'],$poundpos);
}
}
if ($bookmark){
//your code here
}
?>
There are other ways to get the bookmark part from the string, using
explode() for example. This is just one idea.
