PHP_SELF and Session vars

[meta4m]

Hello All,

I'm trying to build a forum as learning exercise.

I've got a session var "$mrdp" (most recently displayed post) which I register at the first page of the site. It passes along fine to the other pages, but when I get to the forum page, it goes away.

I think it has something to do with my forum implementation using $PHP_SELF links to reload the forum page. My question:

Does calling a href="$PHP_SELF" link reset session vars? I can't get my $mrdp var to exist once one of those gets clicked on in the forum.

Thanks in advance for any help. I'm a newbie, btw. : )

for example:

login.php:

session_start();
$member = "login_ok_id";
session_rigistry("member");
echo "<a href='index.php'>Home</a>";

and in the index.php:

session_start(); // you must take it in the first line, then you can use the var $member.
echo "Hello, $member ! ^_";
