I am currently building a plugin and it doesn't know when a user is logged in.

global $current_user;
echo $current_user->ID;

It works when embedded on a template but not on a plugin? I have a custom database that depends on user_id, whenever I insert a record, user_id field always has a zero value while others have the correct one.

The $current_user global isn't setup until right before the 'init' action is called. So any code using it shouldn't be fired until that action or later.

I would also suggest using the get_current_user_id() method instead of getting the global directly.

Try using is_user_logged_in() to check whether the user is logged in. It will return true or false depending on whether the user is logged in.
