Sessions Issue..

[Anon]

If i want to use sessions, and when a user logs on to my site, and if there is no id found the user gets redirected to with a url that includes the session id. But then, depending on the user, if he has cookies turnd off or not. If a cookie was set with the session id i don't wan't to add the session id on every link on the page but if a cookie wasn't set I wan't the session id added to every link printed on the page.

How is this done ?
And how do I add the session id to all links printed ?

If you have PHP compiled with --enable-trans-sid PHP will automagically add the SID to all local links in the page. If you don't have that you can use <?= SID ?> to put it there yourself:

<a href="/local/file.php?<?= SID ?>">Click here</a>

I wouldn't worry about the cookie. If it's there, it's there, if it's not, it's not.

Yes, i know about that -enable-trans-sid thing but i didn't get it to work though.
This is the code i have been testing been so far..

if($PHPSESSID == "") {
session_start();
$Query = "INSERT INTO session VALUES('" . session_id() . "', now())";
mysql_query($Query ,$mysql_link);
header("Location: first.php3?" . SID . "");
} else {
$Query = "UPDATE session SET LastAction=now() WHERE ID='$PHPSESSID'";
mysql_query($Query, $mysql_link);
}

print("Move on: <a href=\"first.php3\">here</a>");

But the SID are not added to that link in the end, what's wrong then ?

I imagine the problem is with the escaping . You should try one of the following:

print 'Move on: <a href="first.php3">here</a>';

or

?>
Move on: <a href="first.php3">here</a>
<?

Thanks for the tip, but the problem was the header part, when i removed that i worked...
