Wordpress/PHP: Problems keeping $_SESSION variable when changing page

Question

I have the code below in the same file:

add_action( 'init', 'iniciaSessao', 1 );
function iniciaSessao() {
    if(!session_id() ) {
        session_start();
    }
}

function info() {
$_SESSION['nome'] = 'meu nome';
}

info();
//session_regenerate_id(true);
wp_redirect($minhaUrl);
exit();

By going to the website homepage (where you are redirecting) and using print_r($_SESSION['nome']); the information set does not appear.

NOTE: the following error message appears when uncommenting the session_regenerate:

session_regenerate_id(): Cannot regenerate Session id - headers already sent

Answer 1

The problem was that the redirect led to another domain (localhost to localhost ip) making wp believe it was another domain and clear the session and cookies.
