Grabbing URL Data

someone1

So i've made a website using PHP, MySQL, and AJAX. Everything in my website requires the use of Javascript, and its pretty much useless otherwise, so i found and modified a script i found online to use PHP to determine if the user has Javascript enabled:

<?php
$js = array_key_exists('js', $_POST) ? $_POST['js'] : '';
if ($js == '')
{
   $js = 'off';
?>

<form id="tester" action="<?php if(isset($_GET['page'])) { echo $PHP_SELF.'?page='.$page; 
} 
else { echo $PHP_SELF; } ?>" method="post">
<p>
<input type="hidden" name="js" value="on" />
</p>
</form>

<script type="text/javascript"><!--
document.getElementById('tester').submit()
//-->
</script>

My problem is, say if i had the url [url]http://.../index.php?page=content.php&id=1[/url]
The line in my javascript checker:

$PHP_SELF.'?page='.$page;

will only output [url]http://.../index.php?page=content.php[/url] as the URL, dropping the remaining

&id=1

How would i go about makign it so that the FULL url path after "page=" will be used?

I think that's because you would need to have;

$PHP_SELF.'?page=$page&id=$id';

maybe??

maybe?

<form id="tester" action="<?php echo (isset($_GET['page'])) ? "{$_SERVER['PHP_SELF']}?page={$page}&id={$id}" : $_SERVER['PHP_SELF']; ?> method="post">

That would work for that particular case, but content.php&id=x will not be the only thing page will equal. I also have a photogallery script that will have lots of variables in it and other scripts with the same thing. Is there a way to grab the FULL URL as a string, and just crop out everything after ?page=?

I have found the solution to my problem:

by replacing:

<?php if(isset($_GET['page'])) { echo $PHP_SELF.'?page='.$page; 
    } 
    else { echo $PHP_SELF; } ?>

with this:

<?php echo $PHP_SELF ."?". $QUERY_STRING;  ?>

everything works fine...

thanks everybody for your assistance!
