My cookie does not want to delete itself

Question

I want to delete a cookie and it does not work.

Here is the code, any ideas?

    setcookie("candidate_site_search", serialize($model->getAttributes()), strtotime('next year'), '/');

    if (isset($_GET['clearFilters']) && ($_GET['clearFilters'] == 1)) {
        //die('cf');
        $model->unsetAttributes();
        setcookie("candidate_site_search", serialize($model->getAttributes()), time() - 60 * 60 * 24 * 30);
        if (isset($_COOKIE['candidate_site_search']))
            unset($_COOKIE['candidate_site_search']);
        if (isset($_COOKIE['site_search']))
            unset($_COOKIE['site_search']);
        $this->redirect(array('/candidate/search'));
    }

After delete, i redirect to the same url from where the request came.

still nothing happens

p.s: I think this cookie is related to Chuck Norris, or at least Superman ...

Delete the cookie using the same optional arguments as when you set the cookie. Like path, domain, etc.. — kittycat, Mar 18 '13 at 08:04
check this [http://stackoverflow.com/questions/686155/remove-a-cookie](http://stackoverflow.com/questions/686155/remove-a-cookie) — M.I.T., Mar 18 '13 at 08:04
Ehm.. According to PHP.net you're doing it right. Are you sure the script is being executed? If you un-comment your die('cf'); does it die with the messages "cf" ? — CoBolt, Mar 18 '13 at 08:08
I know this might sound stupid, but im all out of ideas here. The page you redirect to doesnt set the cookie again, does it? :P Try not redirecting it and just use die(); right after the setcookie. — CoBolt, Mar 18 '13 at 08:13
ok, so there are also some $_COOKIE variables that i need to delete — Ionut Flavius Pogacian, Mar 18 '13 at 08:18

The problem is most likely in the date/time you have set on your server in relation to the time on the client.

For instance if your server is GMT+2 and your client is GMT, then the code above will tell the client to expire the cookie at GMT+1 which is still in the future for the client.

Just use a time that is waaay back in the past so you eliminate any time zone issues:

setcookie("name_of_cookie", "", time() - 60 * 60 * 24 * 30); // should  do it

Why not just `setcookie("name_of_cookie", "", 1);`? – Alasjo Mar 18 '13 at 08:09
IE will bark and ignore this. – Ionut Flavius Pogacian Mar 18 '13 at 08:25
