Is there a standard interface in WordPress for saving a global PHP variable $bgcolor to the user and read it from him anytime he browses to another blog page. There is nothing that will automagically do it for you but it sounds like you just need to save a little bit of user meta, and … Read more
Your page-xyz.php has to look like this: $cookie_set = isset( $_COOKIE[‘mycookie’] ); if ( $_SERVER[‘REQUEST_METHOD’] == ‘POST’ ) : // exec your mysql queries and do else stuff… // after it set your cookie setcookie(‘mycookie’, ‘some value’); $cookie_set = true; endif; if ( $cookie_set ) : // render your content here else : // render … Read more
The issue you have appears because you set your cookies too late. You have to set it before anything will be rendered. Set your cookies in the your-plugin-file.php file.

I’m setup in the same way as described by the OP using custom_user_table and meta_table. I’ve found the session information does actually translate across different pages if you use COOKIE_DOMAIN as … Read more
If you are looking for user only comments then you could try this one ( http://codex.wordpress.org/Function_Reference/wp_set_auth_cookie). This function can be replaced via plugins.
