I am trying to use a cookie with authentication.
This page works once entering user and pass
<?
if ((!$_POST[username]) || (!$_POST[password])) {
header("Location: show_login.html");
exit;
}
$db_name = "testDB";
$table_name = "auth_users";
$connection = @mysql_connect("localhost", "user", "pass") or die(mysql_error());
$db = @mysql_select_db($db_name, $connection) or die(mysql_error());
$sql = "SELECT * FROM $table_name WHERE username ='$_POST[username]' AND password = password('$_POST[password]')";
$result = @mysql_query($sql, $connection) or die(mysql_error());
$num = mysql_num_rows($result);
if ($num != 0) {
$cookie_name = "auth";
$cookie_value = "ok";
$cookie_expire = "0";
$cookie_domain = "domain.com.au";
setcookie($cookie_name, $cookis_value, $cookie_expire, "/", $cookie_domain, 0);
$display_block = "
<p><strong>Secret Menu:</strong></p>
<ul>
<li><a href=\"secretA.php\">secret page A</a>
<li><a href=\"secretB.php\">secret page B</a>
</ul>";
} else {
header("Location: show_login.html");
exit;
}
?>

<body>
<?
echo "$display_block"; ?>

WHen clicking on either secretA.php or secretB.php I am redirected to log in again, it should work. here is the code.
secretB.php
<?php
if ($_COOKIE[auth] == "ok") {
$msg = "<p>Welcome to secret page B, authorised user! </P>";
} else {
header( "Location: /show_login.html");
exit;
}
?>
<HTML>
<HEAD>
<title>Secret Page B:</title>
</HEAD>
<BODY>
<?
echo "$msg"; ?>
</BODY>
</HTML>
