You can now retrieve all values by using:
   $values = $_POST['id'];

If the name does not end with [], then only a single value will be available via the $_POST variable even if the user checks several checkboxes.

I needed to do the exact same thing as jwl007 (sort by clicking links) but I needed it to append the variable to the query string if it didn't already exist. Here's the function I'm using:

<?php
function setGetVar($var, $val){
    $request_uri = $_SERVER["REQUEST_URI"];
    if(strstr($request_uri, $var)) {
        return preg_replace("/$var=[\\d\\w]*/", "$var=$val", $request_uri);
    } elseif(strstr($request_uri, "?")) {
        return $request_uri . "&" . $var . "=" . $val;
    } else {
        return $request_uri . "?" . $var . "=" . $val;
    }
}
?>

<a href="<?php echo setGetVar("orderby", "lname"); ?>">Sort by Last Name</a>
<a href="<?php echo setGetVar("orderby", "fname"); ?>">Sort by First Name</a>

As above the $_SERVER['request_uri']

is replaced in windows iis with

$_SERVER['script_name']

Refer to CanonicalName if you are not getting the ServerName in the $_SERVER[SERVER_NAME] variable....This was a pain to figure out for me...now it works as expected by turning canonical naming on.

Be careful with HTTP_HOST behind a proxy server.   Use these instead.
[HTTP_X_FORWARDED_FOR]
[HTTP_X_FORWARDED_HOST]
[HTTP_X_FORWARDED_SERVER]

In my situation, I used [HTTP_X_FORWARDED_SERVER] in place of [HTTP_HOST] in order get the machine and hostname (www.myurl.com)

So you have an application in your web space, with a URL such as this:

http://<host>/<installation_path>/
