Share login status across subdomains without network

Question

I need to share login status across subdomains in one install. For example, after I login in main site: localhost/dx/, but when I visit test.localhost/dx/ (I remove 'redirect_canonical' to stop automatically redirecting to main site), it's the same page, but I'm not logged in. I figured that it's the cookie problem, I tried to set

 define('COOKIE_DOMAIN', '.loclhost'); // or loclhost
 define('COOKIEPATH', '/');  
 define('SITECOOKIEPATH', '/');

but still not remain logged in subdomains.

Anyone has a solution for this?

You can try like this code:

After installation, open the wp-config.php file in Site B's installation root, and add (or replace) the following lines shortly after the database configuration, modifying them as needed to fit your configuration:

$cookiehash = md5("http://www.example.com/");  // Use Site A's URL

define(CUSTOM_USER_TABLE,'wp_users');           //Change 'wp' to match the prefix set during
define(CUSTOM_USER_META_TABLE,'wp_usermeta');   //  Site A's installation
define('COOKIEPATH', '/');                      //This path should reference Site A's root
define('SITECOOKIEPATH', '/');                  //Should match 'COOKIEPATH'
define('COOKIEHASH', $cookiehash );
