php 4.3.4

how can I fix it?

Oh, I just noticed something, on your 5th post, the page that includes does not POST anything.... it just includes.

Also, instead of testing if($_SESSION['index'] == "") you should use if(isset($_SESSION['index']))

That's where you get your first undefined index error, I think.

yes that is the opening page (index.php) from the book
it supposed to verify if a user has logged on or not and send them to the desired page.

I think this is either faulty or outdated code....

I always use isset(), not to see if it == "" - that should give an error if the index is undefined.

Perhaps instead of include, you should use headers, if you want to redirect.

lol, just for note the book was published 2004.

do you have an example of the isset function?

thanks for your help.

$str1 = "A string!";
$num1 = 52;

if(isset($str1)) echo "It's good!"; //works, $str1 is "A string!"
if(isset($num1)) echo "It's good!"; //works, $num1 is 52
if(isset($var1)) echo "It's good!"; //$var1 was never set, echos nothing

Hope this helps,

P.S. 2004, eh? :)

okay thanks for help. they seem to need to revise the script in the book as there are many errors on those sections similar to undefined.
