Hi 
I have a problem, this is my code:
$db = new mysqli("localhost", "root", "", "blah");
$result1 = $db-query("select * from c_register where email = '$eml' and password = '$pass'");
if($result1-fetch_array())
{
    $auth->createSession();
    $_SESSION['user'] = 'client';
    promptUser("You have successfully logged in!!!","index.php");
}
$db = new mysqli("localhost", "root", "", "blah");
$result2 = $db-query("select * from b_register where email = '$eml' and password = '$pass'");
  if($result2-fetch_array())
{
     $auth->createSession();
     $_SESSION['user'] = 'business';
     promptUser("You have successfully logged in!!!","index.php");
}
$db = new mysqli("localhost", "root", "", "blah");
$result3 = $db-query("select * from g_register where email = '$eml' and password = '$pass'");
  if($result3-fetch_array())
{
    $auth->createSession();
    $_SESSION['user'] = 'employee';
    promptUser("You have successfully logged in!!!","index.php");
}
$db = new mysqli("localhost", "root", "", "blah");
$result4 = $db-query("select * from k_register where email = '$eml' and password = '$pass'");
  if($result4-fetch_array())
{
    $auth->createSession();
    $_SESSION['user'] = 'super';
    promptUser("You have successfully logged in!!!","index.php");
}
  else
{
    promptUser("Username/Password do not match.  Please try again!!!","");
}
Funny enough this code works, but I no that I went about it the wrong way.  I am new with php and mysql, so please help.  I also tried e.gresult4->free(); for all the variable that save the data, and I got this error: Fatal error: Call to a member function free() on a non-object in...
