Normally, when you hit the logout link in WP, you get sent to a warning screen where you have to hit another link to actually log out. Annoying.
add_action('check_admin_referer', 'fotan_logout_without_confirm', 10, 2);
function fotan_logout_without_confirm($action, $result)
{
/**
* Allow logout without confirmation
*/
if ($action == "log-out" && !isset($_GET['_wpnonce'])) {
$redirect_to = isset($_REQUEST['redirect_to']) ? $_REQUEST['redirect_to'] : get_permalink( wp_logout_url() );
$location = str_replace('&', '&', wp_logout_url($redirect_to));
header("Location: $location");
die;
}
}
