Re: [Phplib-users] sourceforge project page down & real $sess->url() stuff

[<an...@sp...>]

Hello Andrew,

Thanks a lot for the reply so I know that I am not alone :)

>What exactly are you doing that generates the URLs you describe?

I use it in a navigationbar, so if I click on one item and than on the
next item the url ever "knows" where I was before. It's ok, but I don't
like it, it looks so ugly. I thought there was something that looks into
the querystring and than deletes doubles and gives the cleaned
querystring
back, but maybe I am wrong. There will come a day for urlbeauty. :)

>I think most people who are still using phplib concluded that the query
>string session fall back was too insecure for most uses and configured

I know but there are also a lot of people who don't allow cookies for
whatever. So I want to use the feature, but as described above its just
for the urlbeauty.

[Phplib-users] sourceforge project page down & real $sess->url() stuff

[<an...@sp...>]

Dear List,

sorry for the previous posting (stupid webmailer) :(.

I noticed that the sourceforge site ist down. Maybe someone is able to fix
this.

But my real problem in the moment is, that I want to use the $sess->url()
functionality, for a new project, and I have the feeling, that something
is going wrong. My problem is that: every new variable will be appended in
the end of the url. So that I have urls like:
http://localhost/?doc=e&doc=f&doc=g .....
and so on. 

I think this behaviour is new, right now I can't remember that it was so
in my  older phplib projects. Does anybody have an idea how to solve this?
I use phplib 7.4.

Thanks in advance

Andreas

Hi Fabrizio,

> Is there still someone around here? :-)
yes! We are!!! Silently...  :)

Good to see that there is still life on this list!!!

It's probably because phplib just WORKS! ;) 
(Although I have to admit that I had quite a few problems in the past with 
cookies and session handling...)

But recently I switched to PHP 4.3.9 & 4.3.10 on apache2 and surprisingly 
both seem to work without problems including php4 sessions, except a PEAR 
configuration problem.

Marko

Re: [Phplib-users] more that one permission!?

[Layne W. <la...@dr...>]

> how can a set on a page more that one permission?

The trick is to set up your permission levels so that multiple levels
can meet the different combinations of access requirements that you need
throughout your project. If you haven't yet, read the relavent section
of the PHPLib manual <http://www.sanisoft.com/phplib/manual/perm.php>.

It is possible that you may need more complexity than exists in PHPLib's
permissions class - I have created a few different perm classes for
various projects that use PHPLib's API, but have different internals as
needed.

And....

If you cannot avoid sending your headers first, you could consider using 
PHP functions ob_start() end ob_end_flush()

You must be sure that there is nothing that gets sent to the browser (not

[Phplib-users] Erro Session!?!

[<ima...@ya...>]

Guys,

I'm having problems!

I'm using PHPLIB library authentication. I'm adding to each page the 
following:

page_open(array("sess" => "My_Session",
                "auth" => "My_Auth",
                "perm" => "My_Perm",
                "user" => "My_User"));

and in the end:

page_close();

but it's warning this message:

*Warning*: session_start(): Cannot send session cache limiter - headers 
already sent (output started at 
/var/www/apache2-default/cad_usuario.php:2) in 
*/usr/share/php4/php/session4.inc* on line *171

*I know that is because of fuction session_start() on file session4.inc, 
but i don't know what to do to solve this problem.

Does anybody have idea of what is happening?

thanks

Yes, the frames are causing this. If I recall correctly, the way to
prevent this is to only use the page_close() function in one of the
frames and none of the others - you'll need to use page_open() in all
the pages to get your session and auth info.

Hello guys!

I using the PHPLIB Library to authenticate my user on my pages, but I'm 
having problems, because on my page a create a frame, and thereis the

the problems is that everytime that a click on a link and open the page,

Rif: Re: Rif: Re: [Phplib-users] is phplib compatible with Apache 2.0?

[Fabrizio E. <fab...@sy...>]

My understanding of the issue is that thread safety is only a concern
with PHP's modules, not any code that may be written in PHP.

---

So was mine, but you know, when you're out of clues,
you start clutching at straws...

----
Well, as you mentioned, your problem is strange enough that I don't have
any good idea what would be causing it. Are you using the
PHP3-compatible session class for PHPlib pretty much as-is, or have you
modified it somehow? If you're using the User class, same question. The
problem you describe would have to be in one of those two areas--you
might want to make sure that your class isn't getting confused with user
data and session data, since they're both stored in the same table by
default.
----

No, I'm using only standard old-style session code, with "multi-record"
session (but every time I checked there wasn't any session data spawning
more than one record). And i use also auth (still "vanilla" phplib code)
and sometimes perm (this is a custom made version).

----
Upgrading to session4 may help you--and it may not. But it's something
to try. If you can send more details about what exactly is going on
(maybe you can add some debugging code to your scripts that prints
messages to a log or something), then I might be able to give a better
answer.
-----

It's really hard to figure what to log and/or debug. There are 2 incident,
in different installations, that I've witnessed in person:

1) in an application I used session to store the values users submit in a
complex input form (so the application "remembers" them each time they have
to input data again). At one time a user went to the form and found default
values that was clearly inserted by another user. No warnings, no errors,
looking in auth_Sessions table and in apache logs I didn't find any clue.

2) in another application i've put a "status" line at the end of every page
that echoes $auth->auth["uname"]. I received a call from an user that
complained to have wrong permissions, so I asked him to read what was
written in the status line: well, it was the name of a different user, that
at that moment was logged in and working from a different client! This
REALLY sent me shivers thru my back. Note that first user's PC is not used
by the second one, and that first user does not know second user password.
So this was not a failed login for sure. I asked the user to logoff and to
login again, no problems, apparently all worked correctly again.
Some other info: I use only cookie for session propagation (i've disabled
get mode, no fallback). In case 2) there was a proxy in between both users
and the servers. In case 1) surely they were connecting via different
network routes.

I'm going to try swapping to session4 code, to see if something changes.
Thank you again for your feedback!

PS: please excuse me for the bad quoting form. Sadly i'm forced to use a
braindead mail client.

As long as you're using PHP in a 'prefork' MPM environment (as the post 
you quoted suggests) then you shouldn't have any real problems. I've 
been running PHP on Apache 2 for quite a while and it hasn't given me 
problems, though I admit, I've always used Session4 for sessions of 
late, so I haven't tested Session '3' on apache 2.

Glad to hear that ;-)

I haven't run into any problems running phplib-based applications with
the old sessioning under Apache 2.  I have a couple of systems that are
under fairly heavy use and have seen no incidents of session data
getting switched as you describe.  However, I will look for it more
closely, now.

Hm. Do you use also auth and perm objects? I use all of them.

As for switching to php4 session support: that didn't work out for me.
As I posted to this list back in February, there seems to be a bug in

that is necessarily a show stopper but, it's not ideal.

First of all, glad to read you again, Nathaniel. It's been years since the
last time :-)
What was making me think was the old argument stating that using PHP4 with
Apache 2.0 was a bad idea.
There has been for a long time (I don't know if it's still there) an
"official" statement on PHP site that warned aginst using php 4 on Apache 2
in a production environment.
I can also submit this link reporting a comment by Rasmus about this:
http://apache.slashdot.org/comments.pl?sid=101407&cid=8644732

The problem I'm experimenting it's very random and difficult to diagnose,
so I was starting to think it could be caused by some part of code that's
not thread safe.

I was going to have a look and see if I could find the problem but, I 
started running in to some other erratic behavior with one of my apps 
that was cured immediately by going back to the original sessioning code.

There was some discussion here sometime back that concluded that it 
probably doesn't make much difference which sessioning one uses and that 
the old sessioning code might even be more efficient.  So, I really 
haven't pursued stomping the bug.

[Phplib-users] is phplib compatible with Apache 2.0?

[Fabrizio E. <fab...@sy...>]

Hi!

Is there still someone around here? :-)

After all these years I continue to use my dear library (with pre-php4
session). Until lately I didin't have any problem.
But I've a couple installation made under apache 2.0 (that's starting to be
the default on many recent distros) that give me serious trouble:
it appears that erratically it happens some sort of "server side session
hijacking": a user logs in and "inherits" session data of a DIFFERENT user
that it's logged at the same time. This is quite rare, but not so much to
be explained with an MD5 collision!
The subject of this post refers to Apache 2 because that is the fact that
those two installations have in common. I've never seen something like this
in a apache 1.3.x installation.

Is there anybody that can share come thought on this? Should I upgrade to
session4? Downgrading Apache version seem quite difficult to do.

Thanks for any input.
Bye!

I'm not familiar with FastTemplates and I'm not sure this has any 
bearing on your problem but, shouldn't you be defining the query string 
($squery) BEFORE you call the query method of your database object with 
the variable?  As written, won't this section of your script send an 
empty query to the database since $squery is undefined at the point you 
call the query method with it?  Or am I missing something?

Hmm... I can't say that I've ever run into a problem like that. It 
sounds like the templating system might be causing the query to execute 
twice, with one of the execution's output being discarded or something. 
However, I can't really be sure. Since you mentioned that it works fine 
when you don't use templates, I'd look for the bug there in any case--it 
sounds like the problem might be in how you've implemented the 
templates, since you said that the bug occurs both with PHPlib Templates 
and FastTemplates. Unfortunately, I don't use a templating system on my 
projects, so I can't offer any more clues as to what might be causing that.

[Phplib-users] PHPLIB duplicate (one is blank) db inserts with Templates...

[<an...@my...>]

Dear list

Been using PHPLib a few years back and started using it again for a project
since the DB class, auth and sessions are just so easy and effective to use.


Im running into a problem however. I have used FastTemplates on my pages and
found that where I have a Insert statement that I try to do with :

$squery = "INSERT INTO auto_messages(message_name,auto_messages) VALUES
('$Message_Name',	'$Message')";
$aDb = new DB_oi_ct;
$aDb->query("$squery");


...as an example, this statement however always (on all pages where I would
do some insert into the db) in one valid row of data entered and one blank
line (Never just one entry) I thought that it might be fastTemplates and
swithed over to phplib's own template but still got one valid db insert and
one blank insert. 

I have also used a Mailing class to send mail and get the same thing, 2
emails arrive - one with values and one blank. 

I tried to print the query to see what the query look like and only one
query (correct) displays. Ive enabled phplib debug echo and it also displays
one query? 


My current environment is : 

Windows XP sp2
Installed phpdev423 - from firepages.com.au 

I have tried to play with the php.ini settings for track_vars, magic quotes
etc (as per phplib doc) and restarted apache. I still get blank database
inserts and blank emails. 

Also note if I take the template out of the picture and only use the DB
object then everything works fine - then my insert query results in one
entry only with valid values etc? 

 Below is an example of code of one page : 

<?
include_once("./php/prepend.php3");
page_open(array ("sess" => "oi_ct_Session",
				 "auth" => "oi_ct_Challenge_Auth",
                 "perm" => "oi_ct_Perm")); $perm->check("admin");
$auth->login_if($again);

if ($auth->auth["uid"] == "nobody")
{
    $relogin = '<A HREF="$sess->purl("$PHP_SELF?again=yes")">Relogin</A>to
this page'; } else {
	$relogin = 'Logged in';
}



$aDb = new DB_oi_ct;
$aDb->query("$squery");
$squery = "	INSERT INTO auto_messages
			(	message_name,
				auto_messages
			)
			VALUES
			(	'$Message_Name',
				'$Message'
			)";


$tpl = new FastTemplate("./html/");
$tpl->define(array(main  => "template.htm",));

$tpl->assign(array(	HEADER 			=> 	"TEST",
					BODY_HEADER 	=>	"NEW MESSAGE
RECORD",
					TOP_MENU 		=>
"MENU",
					MENU_ITEMS 		=> 	"",
					BOTTOM_MENU 	=> 	"",
					BOTTOM_ITEMS 	=> 	""
			));

$text = "Updated ...";

$tpl->assign(BODY_TEXT, $text);
$tpl->parse(MAIN, "main");

$tpl->FastPrint(MAIN);
page_close();
?>

Re: [Phplib-users] Select Box!

[Marylly A. S. <ima...@ya...>]

Like you answered me, I can use the function make_select_list() to make
select box. But how can I make more than one select box if i can't
declare the function more than once?

I'm wanting to do a pge using the PHPLIB Templates with two select boxes
,beind one of them depends on the other to generate the option list and
after select the two select boxes will show a list from the database.

if you didn't understand i can give more details

please, help me

thanks any way

Re: [Phplib-users] Select Box!

[Marylly A. S. <ima...@ya...>]

Andrew,

I've been using the PHPLIB's database abstraction I guess.
But I doesn't matter if it is PHPLIB's data abstraction or not. I hope a 
combobox which works.
I will try the first example that you have writen and later I write the 
results.

see ya
