И скрипта ми изглежда така:

include_once('bookmark_fns.php');
session_start();

$username = $HTTP_POST_VARS['username'];
$password = $HTTP_POST_VARS['passwd'];
$id = $HTTP_SESSION_VARS['userid'];

if ($username && $password)
{
if (login($username, $password))
{
$HTTP_SESSION_VARS['valid_user'] = $username;
}
else
{
include_once('header.php');
echo '<br />';
echo '<center>';
echo '&#205;&#229; &#236;&#238;&#230;&#229; &#228;&#224; &#225;&#250;&#228;&#229;&#242;&#229; &#235;&#238;&#227;&#237;&#224;&#242;.
&#210;&#240;&#255;&#225;&#226;&#224; &#228;&#224; &#241;&#242;&#229; &#235;&#238;&#227;&#237;&#224;&#242;, &#231;&#224; &#228;&#224; &#226;&#232;&#228;&#232;&#242;&#229; &#242;&#224;&#231;&#232; &#241;&#242;&#240;&#224;&#237;&#232;&#246;&#224;.';
do_html_url('login.php', 'Login');
echo '</center>';
include_once('footer.php');
exit;
}
}

include_once('header.php');
echo '<center>';
check_valid_user();
get_user_pictures($HTTP_SESSION_VARS['valid_user']);

$conn = db_connect();
if (!$conn)
return '&#205;&#255;&#236;&#224; &#226;&#240;&#250;&#231;&#234;&#224; &#241; &#225;&#224;&#231;&#224;&#242;&#224; &#228;&#224;&#237;&#237;&#232;, &#236;&#238;&#235;&#255; &#238;&#239;&#232;&#242;&#224;&#233;&#242;&#229; &#241;&#235;&#229;&#228; &#236;&#224;&#235;&#234;&#238;.';

$query = "select rights from user where username=".$HTTP_SESSION_VARS['valid_user']."
and passwd='$password'";
$result = mysql_query($query);

$row = mysql_fetch_assoc($result);

switch($row['rights'])
{
case '1':
display_user_menu();
break;

case '2':
display_user_menu_upload();
break;

case '3':
display_user_menu_delete();
break;
}

echo '</center>';
include_once('footer.php');
