Based on that code, whether or not the user is logged in is determined by checking if the $_SESSION['login_user'] element has a valid user email. So if you want your registration script to log the user in, put the email into that session variable.


On another note, the session_register() function has been obsolete for a long time, and has been removed from PHP altogether as of PHP 5.4. Do not use it! - See the manual entry on sessions for details on how to properly use sessions in modern PHP code.
