http://php.net/setcookie

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.

If you want the cookie to be available in the parent directory, you'll need to set the path for the cookie. Easiest way to do that is to set all your cookies to a path of /, so the cookies are available everywhere on that domain:

setcookie ("mail", $mail, time()+3600*24*365*10, '/');
setcookie ("name", $name, time()+3600*24*365*10, '/');
setcookie ("password", $password, time()+3600*24*365*10, '/');
