get full url of parent page from include file

[mishasoni]

Hello!  I am somewhat new to php and am hoping someone can help me out with a problem.  I have a php page with a php include file that contains javascript.  The javascript is for a stylized sort menu that sorts the current results on the parent page.  Therefore, I need to get the full url (including url variables) of the parent file from within a js script in the include file.  So far this is what I have, but it doesn't work ($pageURL is empty when looking at the page source):

 

parent file:

<?php // get the full page url
$pageURL = 'http';
if ($_SERVER["HTTPS"] == "on") {$pageURL .= "s";}
$pageURL .= "://";
if ($_SERVER["SERVER_PORT"] != "80") {
$pageURL .= $_SERVER["SERVER_NAME"].":".$_SERVER["SERVER_PORT"].$_SERVER["REQUEST_URI"];
} else {
$pageURL .= $_SERVER["SERVER_NAME"].$_SERVER["REQUEST_URI"];
}

?>

.
.
.
<?php include("include.php"); ?>

 

include file:

<script type="text/javascript">

//Contents for a sort menu that sorts the current results on the parent page

menu1[0]='<a href="<?php echo($pageURL);?>&sort=yearDESC">Year: descending</a>'
menu1[1]='<a href="<?php echo($pageURL);?>&sort=yearASC">Year: ascending</a>'
menu1[2]='<a href="<?php echo($pageURL);?>&sort=title">Title: A-Z</a>'

 

Maybe there is a better way to do this?  Any help would be mush appreciated.
