  1. Thank you for this post…. I’m making the same thing with multiple blogs and your tutorial helpt me a lot.

    Ben

  2. I tied the same thing for my site http://www.kochidaily.com. I have two wp installations one on the main site and another in a folder called jobs. I have inserted the following in the wp-config.php in the http://www.kochidaily.com/jobs

    define(‘COOKIE_DOMAIN’, ‘.kochidaily.com’);
    define(‘COOKIEPATH’, ‘/’);
    define(‘CUSTOM_USER_TABLE’, ‘cd_users’);
    define(‘CUSTOM_USER_META_TABLE’, ‘cd_usermeta’);

    and the following in the capabilities file under includes in the jobs wp

    function _init_caps() {
    global $wpdb;
    // $this->cap_key = $wpdb->prefix . ‘capabilities';
    $this->cap_key = ‘cd_capabilities';
    $this->caps = &$this->{$this->cap_key};
    if ( ! is_array( $this->caps ) )
    $this->caps = array();
    $this->get_role_caps();
    }

    I am able to login using the main sites logins to both wordpress installs but unable to share the cookies between the domains. Ie I have to login and logout separately to each install. Loging in into the main site does not log me into the job site. I have to relogin meaning the cookie is not shared.

  4. I had to do something similar, this was my solution:
