PHP Load Page In Target Frame

I have a .php file called memberops which checks a username and password in a SQL database. If the username or password is wrong it returns to the login page. If it is right then it loads the page "home.htm". In addition to this I want it to load a page called [login to view URL] in a frame named "left". The code below is what I have at the moment. What can I change this to to load the home page in the current frame (as it currently does) AND load the menu page in the frame named left? if(mysql_num_rows($res) > 0) { $_SESSION['uname']=$userid; header("Location: home.htm"); } else header("Location: login.htm");
