Hello, all. This is more of a php problem, but i'm not on the general
list and um the cookie problem is part of a php/mysql application . .
. .
So, I have an application where university faculty can enter their
publications in a "scholarly database", but this data can also be
entered by a proxy (i.e., grad student or secretary). I have a number
of cookies that I set and then kill again when someone hits the logout
button:
setcookie ('becool', '', time() - 86400);
setcookie ('user_id', '', time() - 86400);
setcookie ('andyouare', '', time() - 86400);
setcookie ('supereditor', '', time() - 86400);
setcookie ('now_editing', '', time() - 86400);
header('Location: index.php?type=logout');
(the user_id is the id of the person who logged in (through LDAP), the
now_editing is the id of the person whose records are being edited
(i.e., staff member #19 is the user, but they're editing faculty
member #34's work).)
When I look at the cookies on the page they're redirected to (through
the firefox web developer extension), they're all gone. And the
becool cookie is definitely unset (or else you'd be able to visit
pages that require authentication). But when someone logs back in,
and I do my check to see if the person logged in is acting as
themselves or on the behalf of someone, the cookie is magically set to
the last person that had now_editing set. If the browser window is
killed, however, the cookie really is killed.
The first four cookies are set on the login page, but the now_editing
cookie requires you go off to a special "super editor" page for it to
be set.
Here's what a sample cookie value look like:
[now_editing] => 20,Firstname,Lastname
And, I don't know if this is useful, but this is what the function
looks like that checks on whether the user is acting as themselves or
as someone else:
function amISomeoneElse() {
global $set_author;
$true_author_name = $_COOKIE['andyouare'];
if (isset($_COOKIE["now_editing"])) {
// now_editing consists of user_id, fname, lname
$item_bits = explode(",", $_COOKIE[now_editing]);
print "<p align=\"center\"><img src=\"../images/user_edit.gif\" />
Logged in as <strong>SuperEditor</strong> (aka $true_author_name),
editing the work of <strong>$item_bits[1] $item_bits[2]</strong></p>";
$set_author = $item_bits[0];
}
return $set_author;
}
($set_author, at the beginning of the function, is the cookie
user_id.) When this function is called, now_editing shouldn't
exist--but it does.
Anyway, I haven't used cookies much before, and this is driving me
crazy. Any ideas?
Thanks a lot,
Andrew
