Login / Sessions issues

[telefiend]

Hi Php Builders,

I am having problems with my Login script. It works fine on most computers, but I am having issues with a couple computer running Windows 98. Does anybody have any advice about this?

This is the script for the Login screen:

$result_users = mysql_query ("SELECT * FROM users ORDER BY surname ASC") or die ("Database error #1");
$row_users  = mysql_fetch_array($result_users);

// verify user identity

if ($enter) {
$result = mysql_query("SELECT * FROM users WHERE surname='$user' AND password='$password' ");

if ((mysql_num_rows($result))>0) {
global $valid_user;
$valid_user=$user;
session_start();
session_register("valid_user");
header("Location: main.php");
}  

}
?>

Typically, this works just fine, but some people can't get sessions to start for them. If it matters, this is the script that is on the pages once a person makes it inside.

// session control

session_start();
if (session_is_registered("valid_user"))
{ } else {
header ( "Location: index.php");
exit;
}

Why might it work on some computers and some not?

Thank you for any help, T.

Hi,

I ran into this problem yesterday. Someone using Win98/IE5 was not able to log into the app. It was telling them that it timed out. My experience had told me that cookies were probably disabled. Sure enough! When I was finally able to dig and find where the setting was (Internet options, Security tab, and then under the certificates button, if I remember correctly) and turn cookies on then everything worked fine.

Hope this helps,
Jack
