How to get variable passed in URL

[Darkmatter5]

If my URL would be index.php?page=nothing.php, how can I print or use the "page" variable?

I believe you'll need to parse window.location yourself.

[webster08]

split the "page=" variable of your window.location; then call key[1] from the array that the split creates.

I used var page=document.location.search.substring(5)

 

But the I need to call the page variable into the location function.  Here's my code:

var page=document.location.search.substring(5)
        if(page==undefined) {
            location='gateway.php';
        }
        else { location="page"; }

 

How do I get it to output the value of page instead of http://mydomain.com/page

Let me repost my full code.

<?php
    if(isset($HTTP_COOKIE_VARS["resolution"])) {
        if(!isset($_GET

---

)) {
            header("Location: gateway.php");
        }
        else { header("Location: $_GET

---

"); }
    }
    else {
?>
<script language="javascript">
    <!--
    writeCookie();
    function writeCookie() {
        var today=new Date();
        var the_date=new Date("December 31, 2023");
        var the_cookie_date=the_date.toGMTString();
        var the_cookie="resolution="+ screen.width +"x"+ screen.height;
        var the_cookie=the_cookie + ";expires=" + the_cookie_date;
        document.cookie=the_cookie
        
        var page=document.location.search.substring(5)
        if(page==undefined) {
            location='gateway.php';
        }
        else { location=page; }
    }
    //-->
</script>
<?php
    }
?>

 

This code mostly works, the page variable in the javascript works great, but the line

"else { location=page; }"

doesn't work right.  It's output in the address bar is http://mydomain.com/=res_maint.php.

 

res_maint.php is what the page variable is set to, but it's putting in that "=" and causing the browser to not find the page.  How can I fix this?
