After doing a bit of processing, I want to set a cookie value to user input and then redirect them to a new page. However, the cookie is not getting set. If I comment out the redirect, then the cookie is set successfully. I assume this is a header issue of some sort. What is the best workaround for this situation?

if($form_submitted) {
    ...
    setcookie('type_id', $new_type_id, time() + 60*60*24*30);
    header("Location: $url");
    exit;
}

Note that setcookie returns true in either case and I get no errors/warnings/notices.

EDIT: I am using Unix/Apache/MySQL/PHP

Did you try settings the cookie after the header()?

sikx - The cookie does not get set either if I use header() first.

I had a problem where Location: http://domain.com/asd wouldn't save the cookie. Doing Location: /asd solved it for me.

If you have human urls (like www.domain.com/path1/path2/), then you must set cookie path to / to work for all paths, not just current one.

if($form_submitted) {
    ...
    setcookie('type_id', $new_type_id, time() + 60*60*24*30, '/');
    header("Location: $url");
    exit;
}

From PHP manual:

The path on the server in which the cookie will be available on. If set to '/', the cookie will be available within the entire domain . If set to '/foo/', the cookie will only be available within the /foo/ directory and all sub-directories such as /foo/bar/ of domain . The default value is the current directory that the cookie is being set in.
