code not doing anything

This is part of the code to a login form. The only file is index.php. The code continues but it what you get after you have successfully logged in. It doesn't matter what I put the the login form, when I hit the "log in" button, if just reloads the page, with no errors or anything. I have the database and everything set up correctly as far as I know. I'm not sure if you need anymore information. If you do I can get it to you. Any help would be greatly appreciated. I have been stuck on this for a few hours now.

  1. session_start();
  2. if ($form == 'sent') {
  3.     unset($HTTP_SESSION_VARS);
  4.     session_destroy();
  5. }
  6. global $asess_name, $asess_passwd, $asess_data;
  7. session_register("asess_name");
  8. session_register("asess_passwd");
  9. session_register("asess_data");
  10. include('../vars.php');
  11. mysql_connect($db_host, $db_user, $db_pwd);
  12. mysql_select_db($db_name);
  13. if (!isset($HTTP_SESSION_VARS["asess_name"])) {
  14.     if ($form = 'sent' && ereg($self_name, $HTTP_REFERER)) {
  15.         if ($login == "" || $passwd == "" || ereg('%', $login) || ereg('%', $passwd)) {
  16.             echo("<html><head><title>$title</title></head><body><p align=center><font face=$fontface><b>

If your system has register_globals turned off in php.ini (the default in R5), then it doesn't look as if your code is dealing with it (e.g. if ($form == "sent").

It may not be related but on line 14 it seems that you would want it to say:
if ($form == "sent" ...

Well, I tried added the extra = and turning on global variables, still nothing. It acts as though I just refreshed the page.

When I ran your code, it tries to go to control/ which seems to be the way you coded it. Don't know why you can't get out of the initial module

Hi there,
I think the problem might be that you never assign values from the $_POST array into your variables ($login, $passwd, etc.) Unless you do this in your include('../vars.php'). But other wise your variable will always be empty.
$me = new Person();
if (isset($_COOKIE)){
$me->eat($_COOKIE);
} else { $me->starve(); }

Well, I just took out the include statement and just copied the data in its place. vars.php is just my database information. Still nothing...
