and in processing script I register username and password:-
<?php
session_start();
$conn = mysql_connect("localhost", "root") or die(mysql_error());
$db = mysql_select_db("database", $conn) or die(mysql_error());
$sql = "SELECT id FROM users WHERE user='$_POST[username]' and password=
'$_POST[password]'";
$result = mysql_query($sql) or die (mysql_error());
$row = mysql_fetch_array ( $result );
$id = $row["id"];
$username=$_POST["username"];
$password=$_POST["password"];
if (mysql_num_rows($result) == 1) {
session_register("id");
session_register("username");
session_register("password");
header("Location: menu.php");
}
else {
echo "You`re not authorized to see this page!";
echo "<p><a href=form.php>Please login!</a></p>";
}
?>
I carry on username and password as session variables and it works fine unless the PHP settings are set to display all warnings and errors!
Then after starting form.php (the most upper script)I get:
Notice: Use of undefined constant username - assumed 'username' in c:\apache\htdocs\iwa2003_12\form.php on line 4
Notice: Use of undefined constant password - assumed 'password' in c:\apache\htdocs\iwa2003_12\form.php on line 4
How do I get rid of this! It`s very important!
If my authentication system is bad could you suggest something else?
if ((!$_SESSION['username']) ¦¦ (!$_SESSION['password']))
and it should fix it right up
Also, instead of session_register() use the superglobals. Instead of
session_register("username");
try this
$_SESSION['username'] = $username;

Notice: Undefined index: username in c:\apache\htdocs\iwa2003_12\form.php on line 4
but after logging in everything is OK now!
I get that message when starting form.php or other files that require aunthentication and are directed to form.php!
I already used $_SESSION... but it did the same thing!
nb.: there are forms of punctuation in the English language other than the exclamation point!
;)!
if ((empty ($_SESSION['username'])) ¦¦ (empty ($_SESSION['password']))) {
I just combined your code a bit and came to this!
Everythig is OK now!
Thanx man, you`re a true saviour!
