I am trying to keep a MySQL table of all currently online users for a system
I'm making. It's pretty simple to add the username to the list when they
login, but I don't know how to remove their username when they leave (unless
they click the logout button). Basically I want to be able to keep a list
of all currently active users. So if they close out their browser, it will
remove their name from the list (within a reasonable time frame). I'm
basically trying to keep this list of online users for a chat application
I'm building. Anyone have any suggestions on how to do this?

Thanks,

No can do.

You'll just have to expire people from inactivity.

First, let me assure you that this is not one of those shady pyramid schemes
you've been hearing about. No, sir. Our model is the trapezoid!

attached mail follows:

Hi,
If you are using a database on your server you can
do this as follows:
1. Make a table named
active_users(userid,last_access);
2. Record every visit of a user to any page.
3. you can delete the entries from this table on a
condition like ::
delete from active_users where last_access is less
than (currenttime-MAX_EXPIRE_TIME)
4. Display row count of active_users to visitors.

This is just a hint. Some knowldge of php/any database
assumed ,

Revert back with any comment or problem.

Is it possible to make a table of all logged in users session ids and then
check to see if the session still exists every couple minutes? So every
minute or two, it would go through the table and for each record it would
get the session id, then check that session id to see if it's still in
existance. Is this possible to do?

Thanks,

Sneak past the PHP file upload limits.

attached mail follows:

I have files contained in a download directory (.doc, .xls etc files)
so I can't request authentication on each download from insie the files.
I use authentication against a DB for the rest of the site and all pages are
protected this way.
My only way to protect these download files is to place server
authentication on the folders they are contained in.

To avoid having to manage my users again as server users, does anyone know
how to set the HTTP_AUTHORIZATION variable at time of request?
I don't need high security, so the page setting the HTTP_AUTHORIZATION is
protected but does contain the username and pw couplet for the
HTTP_AUTHORIZATION setting.
Anyone know how? I know we stamped out URL methods of passing username and
pasword couplets but maybe there's another way?

This doesn't work
$_SERVER['HTTP_AUTHORIZATION'] = "Basic
".base64_encode("username:password");
because you can't appear to set this variable, only the server can set it
after it receives a
header('WWW-Authenticate: Basic realm="Test Authentication System"');
header.

thanks
Alan

There authorizations settings are supposed to be sent back to the server
by the client so you cannot generate them with php. Your option include
using .htpasswd that checks against a mysql database (please ask in the
apache list.) and keeping your downloads 'offline' and delivering them
through a php script. The second suggested has been discussed to
exaustion in this list in the past.

Thanks - I suppose I was thinking of building (via PHP) and client JS script
to set the property at the client. But anyway the offline way is the
answer - shold have thought of that.

Some things crop up while coding that I do not often use, so that I tend to
forget the proper way to handle them and end up researching it and going
through the same inoperable code again and again until I end up with
something that works.

Finally decided to host the code on my site and thought someone else might
benefit from it.

Storing Images in MySQL and Displaying them with PHP:

They all have working demos except for the Imaging Database stuff. Hope
these can help somebody. Plan to be adding more soon.

Hi all,

I have an extrange problem with the session cookie:

In all my pages there I have this two lines to start the session:

session_name('jcwse');
session_start();

When I access my website, at any page, everytyhink works OK, and the
session cookie is set with no problem except for links.

In the fist page I aceess, all links are appended with the session ID.
I mean that in every link, the ?jcwse=da22311212 ... is appended. This
occurs just on the load of first page (not any else). If I reload the
page, then links are formed correctly with no session ID (And sessions
works perfect).

This problem only arises on my ISP hosting (Linux+Apache 1.3) and does
not show on my devel computer (Windows+Apache 2.0). I've been searching
the manual, but found no explanation about that.

Any help will be really welcome.
Regards,
Jordi.

attached mail follows:

shouldn't session_start() come first?

also remember that your devel computer might have different settings in
the PHP.ini file to that of your ISP, probably register_globals is set
to off. I would check it.

I mean that in every link, the ?jcwse=da22311212 ... is appended. This

occurs just on the load of first page (not any else). If I reload the
page, then links are formed correctly with no session ID (And sessions

works perfect).

This problem only arises on my ISP hosting (Linux+Apache 1.3) and does

not show on my devel computer (Windows+Apache 2.0). I've been searching

the manual, but found no explanation about that.

Any help will be really welcome.
Regards,
Jordi.

Sorry forgot it: The two platforms run PHP 4.3.7

Thanks again,
Jordi.

Angelo, thanks for your comments.

session_name must go before session_start.

I think register_globals has nothing to do with session cookies. I
always work with register_globals = off as recommended.

About the cookie params (In PHP.INI) I checked them on the two platforms
with phpinfo() and are exactly the same.

I'm relly lost with this issue. It is not a browser problem, because
browsers are accepting (and saving) the cookies. I tested it with
Firefox, MSIE and Mozilla, and always have the same issue.

Why the first page loaded, and only the first one, passes the session ID
on the URL? I think perhaps could be something related with the system
trying to read the cookie on the same page that first created it. But
don't find a way to solve it.

Thanks for your time,
Jordi.

Was your binary compiled with --enable-trans-sid? If so, I imagine the
explanation would be something along the lines that because the session
manager doesn't know whether you have cookies enabled until it gets a cookie
back, it uses trans_sid. On the second page view, it gets a cookie, and
starts using cookies instead.

No research went into this; it's just a guess. ;)

Source: http://www.php.net/set_cookie
[snip]
Once the cookies have been set, they can be accessed on the next page
load with the $_COOKIE or $HTTP_COOKIE_VARS arrays.
[/snip]

Since PHP cannot access a cookie right after it has been set PHP cannot
be sure if the cookie has been accepted on client-side (user might deny
cookies). Therefore PHP chooses another way of storing the current
session id until next page has been loaded (GET-param, hidden-field...).

Thanks Torben,

The binary is not compiled with --enable-trans-sid. But I've seen that
the ISP changed a param in the PHP.INI, and they changed
session.use_trans_sid setting it to 1.

I tested setting it on my devel computer and really now the problem
reproduces here :) So I think this could be really the problem.

Now I should talk to the provider to not set this parameter to ON by
default, because the security risk on it (As stated on the manuals).

On the sessions manuals, says that this parameter can only be set on
PHP_INI_SYSTEM and PHP_INI_PERDIR, but in the ini_set() manual says it
can be set in PHP_INI_ALL. I think the first is correct and the second
is not as I tried setting it with ini_set with no result.

I cannot understand this change from the provider as it is a security
risk as the comments in PHP.INI says:

; trans sid support is disabled by default.
; Use of trans sid may risk your users security.
; Use this option with caution.
; - User may send URL contains active session ID
; to other person via. email/irc/etc.
; - URL that contains active session ID may be stored
; in publically accessible computer.
; - User may access your site with the same session ID
; always using URL stored in browser's history or bookmarks.

Thanks for your valuable help. Now *I've seen where the problem is*, and
I can look for a solution.

Regards,
Jordi.

Hi all,

I have a PHP file. and when it loads it creates an object for my
database :

include("db_class.inc");

fine.

I make a couple of calls to the database class this is also working
fine. Then I post the page but to itself and then I go into a function
(lets call it xfunction) which is ONLY accessed once the form has been
posted and I get a fatal error:

Fatal error: Call to a member function on a non-object in c:\program
files\apache group\apache\htdocs\zero\opdocument.php on line 98

From what I've read my database object is not instatiated and therefore
is in theory not an object. However I check before I go into the
xfunction to see if the object is set and it is, then once in the
function (where the error occurs) I test to see if the object is set
again and it tells me that the object is not set.

What could be the reason for the object not being set once being called
in the function (xfunction)?? I have googled and many people get this
error but not many have a clear solution.

Any help or suggestions will be appreciated.
Thanks

Angelo

You might as well add a reference of your db-object to global scope.

[code]
$GLOBALS['_db_object'] =& $db;
[/code]

Then you could access it anywhere in your code like this:

[code]
$GLOBALS['_db_object']->sumbitQuery($query);
[/code]

Hello all,

i have a question concerning the $_SESSION stuff.
i have a domain registered with online webspace on this webspace i have put a litte bit of code that will send the visitor's of the website to my server using a frame. I open one frame full-screen size and i let it open MY_IP/base/index.php as page.
i then have a login page which uses $_SESSION and which sends you to either MY_IP/login1/index.php or MY_IP/login2/index.php depending on your username. (which are stored in mysql)
this all works fine. i get redirected to the right page and all. but then on the new page the session doesn't work anymore.
so the user gets a error for not being logged in and returns to the login page at /base

AND here's the strange thing.. when i open it using the http://MY_IP link it all works great.
it just doesn't when i use the frame via my hosting provider. So i tried to make a fram on my site which is exactly the same as the frame at the hosting provider. And it all works great aswell. just not when i place the frame at my Hosting Prov.

has anybody got a clue how to do this?

thanx

Dennis
