Refreshing a page with javascript using php header('location')

Question

I want use a single php file to handle all of my voting requests.

Currently the script will, if siteType isn't set, forward the user and display a message. If the user has JS on then it will return a json object and ajax the page.

        if(!isset($_COOKIE['siteType'])){
            displayMessages('bad', 'Before you can continue you must select which category you would like to be in.');
            header('Location:/');
            exit;
        }

I need it as that if this php code above is executed the page will reload, i assume with javascript and reading the http headers?

[Edit] I didn't make myself clear enough, but this is a ajax request. I don't output any html. So this really is just about getting js to handle the header?

Your not allowed to use header() AFTER outputting data to the HTTP stream. — Bjørne Malmanger

You can't Refreshing a page with javascript using php header('location') Because, header('Location: xxx'); must be the only output of your PHP script, it is a header, you can not put it after javascript syntax

cheer fella. Boy i don't think i made the question clear enough. So the javascript won't know when to reload the page.

The javascript will know when to reload the page, if you put that javascript code inside braces { }.

I am sure. if(!isset($_COOKIE['siteType'])){ window.location.reload(); }

Maybe this would be some solution for you,

if(!isset($_COOKIE['siteType'])){
     displayMessages('bad', 'Before you can continue you must select which category you would like to be in.');
     echo '<script>window.location.reload()</script>';
     exit;
 }

I'd go with a meta refresh tag instead of a script in case JS is disabled.
