(location.href) and pop-up window

    I'm not really good with javascript and need help with a problem. I'm creating a pop-up window that goes to another site but sends the url it's coming from in the url it's going to.

    Ok here's what I have if that's confusing.
    <head>
<script type="text/javascript">
function popupwin(url) 
{
 var width  = 650;
 var height = 250;
 var left   = (screen.width  - width)/2;
 var top    = (screen.height - height)/2;
 var params = 'width='+width+', height='+height;
 params += ', top='+top+', left='+left;
 params += ', scrollbars=1';
 newwin=window.open(url,'popupwin', params);
 if (window.focus) {newwin.focus()}
 return false;
}
</script>
</head>
<body>
<a href="javascript: void(0)" onClick="popupwin('http://example.com/check.php?id=http://$_SERVER[SERVER_NAME]$_SERVER[REQUEST_URI]'); return false;">Centered popup window</a>
</body>
    Code (markup):
    Now that above code works fine in most cases and on most sites. The problem is that one forum I've tried it on has a seo mod which means the php comand $_SERVER[REQUEST_URI] isn't the same that's in the address bar. Instead of showing 
    http://sitename.com/forum/main-forum/1-test-post-title-some-list.html
    Code (markup):
    it's showing 
    http://sitename.com/forum/showthread.php?p=1
    Code (markup):
    After Googling I know that document.write(location.href) will give me the exact url of the seo url as it appears in the address bar which is what I want. Can anyone show me how to combine document.write(location.href) with my code. I know it's probably easy for most but I only really know basic html and php and I'm only new to javascript.

    Thanks in advance.

    Something like:
    
<a href="javascript: void(0)" onClick="popupwin('http://example.com/check.php?id=' + location.href + '); return false;">Centered popup window</a>

    <a href="javascript: void(0)" onClick="popupwin('http://example.com/check.php?id=' +encodeURIComponent(document.location.href)); return false;">Centered popup window</a>

    Best to encode the href before sending it to your page.
