PHP Code:

$getuser = $db->query_read("SELECT userid FROM user WHERE username='".$db->escape_string($username)."'");
$num_users = $db->num_rows($getuser);

if ($num_users == 1)
{
     $user = $db->fetch_array($getuser); 
     echo("The userid for $username is <b>$user[userid]</b>");
}
else
{
     echo("The Username Does Not Exist");
} 


Try that, let me know if you have any problems.

Thanks,

Derek
