[PHP-DB] load page in another frame

[Velen]

Hi

I have 3 frames on my index page using frameset.  I want to display another 
content in the other frames when a user has logged in successfully.

My code is like that:  

## if user exists and have corresponding password mysql_num_rows >0

if(mysql_num_rows($res) != 0) {  
   
xxxxx code to display page in target=main ;
      
 } else {

echo "<br>";
include("left_content.html");
 include(INC_DIR."my_style.php");
    unset($_SESSION['userid']);
    unset($_SESSION['passwd']);

    echo "<br><b>Login Failed</b> Try Again!";
 include(INC_DIR."user_login.php");

 }


Please help.

Thanks.

Velen
