I'm really new at this authentification thing...
What I want do to:
1- a user appears
2- he fills a form (easy)
3- gain access to the page (?)
4- no one else can log-on until the user who is logged quits (very
important) (????)
5- inside the user can surf in diferent php files without being asked for
new athentification (????)
-----------------------------------
3 - Trying to authentificate user the warnings bellow appear:
Warning: Cannot send session cache limiter - headers
already sent
Warning: Cannot add header information - headers already
sent by (
Line of the first Warning:
// Main ----------
session_start();
Line of second warning:
// Relocate back to the login page
header("Location: index.php");
5- How can a user surf in diferent pages with the same loggin?
Thanks

Rui
You will have to check a session attribute at the start of each of your
scripts that you want to protect to ensure that the user has logged on.
Locking out other users whilst this user is logged on will mean flipping
some flag in a database table or creating a row that tells your login script
that someone is altready logged on. Problem is that this row will have to
get cleared after a certain timeout else noone will be able to logon again
even though the original user has gone away. The errors you are getting are
because you are sending http headers - session.start() sends an http header
as a session cookie and obviously header() as well - you cannot send http
headers once html output to the browser has started so check that these
functions are called first... you can use output buffering if this poses a
logical problem for your scripts.
<pseudo code>
<?
// Protected script
// Assume db is connected already
session.start();
if (!isset($_SESSION['logged_on'])) {
$rs = mydb_query('select 1 from user_already_logged_in');
$in = (mydb_num_rows($rs) == 1);
header('Location: http://mysite.com/'.($in ? 'sorry.php' : 'login.php'));
exit();
}
// User is logged in ...
.
.
?>
</pseudo code>

Hi,
I don't know if this is what you need but I'm using authentication on
IIS 5.1 & PHP 4.3.0 with this configuration:
PHP:
register_globals off
IIS config:
Anonymous access off
Integrated windows authentication on
Cheers,
Juraj

Thanks Rich, and Rico...
I turned register_globals on to no effect.
The only odd thing I am doing for IIS is that I
installed PHP under the ISAPI filters tab as well as
the configuration button. Normally I only install
under the configuration button. But it doesn't seem to
help.
Thanks!

The good news is it's possible. The bad news is that it's not possible using
PHP alone.
You can't do client-side stuff with a server-side script.
You need to write that bit in Javascript, I'm afraid, so the code can run on
the user's browser.

Far be it from me to question the wisdom of tweaking the headers, but why do
you need them at all?
Why can't you just do:
<a href ="filename.txt">click here</a>
which, so far as I can see, will load said text page into the user's browser
window as soon as they click on the link. If the user then wants to save it,
they can use the browser's Save As function.
Too easy?

Yeah, but the title of this thread says to download a TEXT FILE, not a Word
document.
No-one with any sense would ever download a Microsoft Word document off the
internet by choice, unless they had a serious amount of trust in the web
site owner, were browsing over a secure connection using SSL, and said
document was digitally signed with a PHP signature or similar. And even
then, you'd want to make sure your virus checker was switched on. This is
because Microsoft Word documents, like executables, CAN CARRY VIRUSES
(called Word Macros).
...and if you should _ever_ discover how to force someone to download
something against their will, then that of course would be highly
unethical...
Maybe I'm just missing the point here. Is it really TEXT documents you're
interested in, or something else? If it's text documents only, then my
original suggestion still stands. If it's something more sinister then
perhaps we should consider changing the thread title.

Hi folks,
we just upgraded to the newest PHP from 4.3.0. I´m a little bit surprised
because of the manual saying that this should be a security fix only.
Unfortunately, serveral extensions fail to work.
PHP 4.3.1 is running with IIS5.0 (no comments on that please). Runing as a
CGI. with version 4.3.0 everything was fine. After the upgrade extensions
CURL and MSSQL fail to work. The failure is that no page is returned, the
process is then stopped after 300 seconds by IIS with a timeout error.
The ini points to
extension_dir = c:\php\extensions\
where the extensions reside. Moving the "faulty" extensions to then system32
dir does not help either.
Am I doing anything wrong?!
Regards,
Chris

I had a similar problem installing PHP 4.3.1. There appear to be more than a
few php libraries that Windows has problems finding. What I did was the
following:
In php.ini, I set the extension_dir to nothing:
extension_dir =
Then I moved most everying in the dlls and extension directories of the php
distribution into \windows\system32 (at least the ones I needed).
It worked for me, so good luck
