RE: [PHP] $_session/$_cookie trouble

What am I missing here?
Whatever it is on line 2 of assessresult.inc.php that is causing output
to be started!
More seriously, there is something on line 2 of that file that is
causing something to be sent to the browser, which in turn causes the
http headers to be sent. Once those headers have been sent, nothing else
that wants to send headers, which includes starting the session and
setting cookies, can be done.
Either eliminate whatever it is on line 2 that is sending output, or
move the session_start() and/or setcookie() calls above it. (This early
in the file, prime candidate is actually a stray blank line outside your
?php tag, but that's only a guess based on past experience of many
people in this list...!!)
Cheers!
Mike

I would have thought it was obvious, the file assessresult.inc.php is
being called before your session_start(). Have you put your code before
every include?

Re: [PHP] $_session/$_cookie trouble
Igor
Thanks for the link. It was suggested that I must put the session_start()
before all code on the parent page. I am no longer getting the error
messages,so I am assuming I am making progress, however I have yet to be
able to get the $_SESSION or $_COOKIE to produce results...such as the
ability to echo them.
Thanks for your help.

Re: [PHP] $_session/$_cookie trouble
Ashley
There are 3 include files, the first is all html, but it has a form, so I
put the session_start above the DTD and I no longer get the error messages.
I had the session_start at the beginning of the second file, the php
processing file, but that produced the error. It seemed to be calling to
itself (if that does not sound too naive).
As I mentioned in a post above, I am no longer getting the error message,
but have been unable to get either the $_SESSION or the cookie to produce
results...
Thanks for your help.

There it is then. The HTML file causes the headers to be sent. Any

Re: [PHP] $_session/$_cookie trouble
Thanks again, dont see any DOM
As I mentioned I am no longer getting error message, but not sure it is
working.
I have this at the begining of the first file.
?php
session_start();
setcookie('sale_cookie','$sale_value', time()-3600);
setcookie('assess_cookie','$assess_value', time()-3600);
if (isset($_COOKIE['sale_cookie']) isset($_COOKIE['assess_cookie']))
{
$_SESSION['sale_value'] = $_COOKIE['sale_cookie'];
$_SESSION['assess_value'] = $_COOKIE['assess_cookie'];
}
?
I have tried this
echo $sale_value;
echo $_SESSION['assess_value'];
echo $_COOKIE['sale_cookie'];
I have also removed all of the if() and still not had success
None of which are producing results...
Anyone see where I am going wrong... I have spent all day online, in the
books, in the manual...
Thanks again

Take the values out of single quotes, else it sets them as strings,

Looks to me like you are trying to set and retrieve a cookie on the same
page. It doesn't work that way. Set it, access it on the next page...
or, set it, and then redirect to the same page.. being sure to send a
flag to hide the setcookie function to avoid the dreaded infinite loop.
Also, Setting a cookie's expire param to history will delete it... so
I don't think that is what you want to do.

Maybe I'm missing something, but why are you using session vars and
cookie vars like you are? If you start a session it creates a cookie to
track the session and the session persists your session vars. Why not
just use session vars?

line 2
I don't know what the error is, but something evident is that on Linux
session.auto_start = 1 is NOT working properly.
On Windows it is not necessary to explicitly start the session to use
the $_SESSION, so no need to session_start().
If on Linux I add session_start() at the top of each script, the
script executes well.
I want to know why session.auto_start does not work on Linux.

Re: [PHP] $_SESSION NOT WORKING
Yes, that way it works. Thanx. But the Windows version of the same code and the same php.ini ***does not *** need the session_start() because it has the session.auto_start = 1 inside php.ini. The thing is, I think session.auto_start = 1 does not work on Linux. Is this a bug?

Re: [PHP] $_SESSION v. Cookies
I can't see PHP sessions slowing down your site by that amount. As someone said, it should be no more than a split second. If you are having that much of a problem with them, then I would say it is either your implementation, or another determining factor. I would not, personally, stray away from PHP's GC of sessions. I would imagine that any third-party concoction could not be any faster. I would however, check to see how long PHP takes to clean up defunct sessions, and also monitor how many sessions are lying around at any given time.

If you pass it to ini_set(), it will appear to work -- you won't get an error and successive calls to phpinfo() will show the new value; however, by the time PHP gets far enough down the chain to execute your ini_set() command, PHP has already determined whether it should register global variables. The manual indicates that this wasn't always the case, but (not knowing the internals then or now) I don't understand how.

sorry tedd; obviously i was hasty to post. but i figured just looking for
the obvious would be a good exercise as i cant count the times ive launched
into an exhaustive search for the problem when its really something silly
ive overlooked. that said; i know ur smart and you always post hard
problems for 'the gang' ;)
anyway, taking the cue from some of the other responses, have you looked at
the page on session_write_close() ?
http://us2.php.net/manual/en/function.session-write-close.php
its kind of interesting; it looks like lots of people have run into issues
using the location header to redirect clients to another script after a form
submission. its never happened to me (knock on wood) but anyway some of the
posts on that page may be worth reading.
also, though it wont answer your question about why its happening, i was
thinking you might alter the flow of ur scripts to see if you can get the
same behavior on both sites. heres what i was thinking:
add a hidden input to the form (from index.php)
input type=hidden name=formsubmission value=1 /
then after you call session_start() in index.php, have the following
if(isset($_POST['formsubmission']) $_POST['formsubmission'] == '1')) {
include('part2.php'); // process form submission
}
then, make the following adjustments to part2.php
remove the call to session_start()
remove the call to header(location ...
remove the call to exit()
i think this will have the effect that the work flow is unaltered, but the
organization of the logic on the back end will be different. effectively
the call to header(location... will be removed so we would be able to tell
if the issue is related to that.

Re: [PHP] $_SESSION problem
it looks fine to me. but i want to share one bad experience with sessions.
the code i wrote work just fine on my testing server (please note, the
phpinfo is same with
my production server).
after days of figuring out why the session do not work. finally, i found the
solutions.
the solutions is to add a
@session_write_close() on the end of the execution code. on my case it
happen
every time i forward the page. so adding the @session_write_close before the
header('location: ') fix the problem.
this might be a possible explanation..
Re: [PHP] $_SESSION problem
I believe you can accomplish the same thing by just putting this in:
register_shutdown_function('session_write_close');

the solutions is to add a
@session_write_close() on the end of the execution code. on my case it
happen
every time i forward the page. so adding the @session_write_close before the
header('location: ') fix the problem.
this might be a possible explanation..

Hi Davis, thanks for the reply.
I think that I've found the problem... But if you (or anyone else) can
confirm I would appreciate.
Sometimes in my code I use the Header('Location: index.php?var=value');
and I've found out (I think) that when one of these headers are executed
by PHP, the rest of the script gets executed.
I'm thinking that this is the problem because I've eliminated all the
occurrences where the SESSION var was cleared until only one exists and
it was after a Location Header.
I've put an exit(); after the header and the problem was gone... :)
Is this the correct PHP/HTML behavior or is there another problem? Am I
supposed to put an exit(); after a header Location to make sure that
no more code gets executed?
Thanks

Redirecting using a Location header is not the only thing you can do
with the header() function. It will never end processing of the script
no matter what you pass to it. The example on the manual page for the
header() function says as much (http://php.net/header), you read that right?
?php
header(Location: http://www.example.com/;); /* Redirect browser */
/* Make sure that code below does not get executed when we redirect. */
exit;

RE: [PHP] $_SESSION saves all values but Class -- works on one server but not another?!
You are correct, however that also seems to have to do with the actual class or php code and not a server configuration. If I copy my PHP files to the 'other' server, everything works as expected -- no change in code required. This is why I suspect it is a PHP/Apache/php.ini type of problem. But as I tried to illustrate, the php.ini seems to be nearly the same on both servers. -Original Message- From: Richard Lynch [mailto:[EMAIL PROTECTED] Sent: Thursday, January 19, 2006 2:46 PM To: Daevid Vincent Cc: php-general@lists.php.net; [EMAIL PROTECTED] Subject: RE: [PHP] $_SESSION saves all values but Class -- works on one server but not another?!

On Sun, June 26, 2005 7:33 am, Alessandro Rosa said: (a) : After saving a couple of data into two $_SESSION variables from a form, (b) : I used the header() function to redirect the browser to (c) : display another page. (c) needs ?php session_start();? at the top, just like (a) and (b) and (z) for any other page you want to use your session data. Also, *WHY* redirect the browser and chew up an HTTP connection and make your application twice as slow? Plus, with the session_start() in there, you're going to duplicate all the effort you've already gone to to build up the session data structure (overhead). At that point in your script, you could just include (c) and be done with it. It's a heck of a lot easier to debug without feeling like you're the pinball in a fast-paced game of HTTP redirects, imho. You also make life easier on cURL and other programmatic access of your site, if you don't force them to play follow the bouncing ball to track down what they asked for. Just give it to them already. :-) I played with header(Location: ) in my early PHP days, and stopped using it rather quickly, unless I actually have a URL I want to maintain for the search engines for awhile, but the document has actually moved. Just because the re-direct works doesn't make it the best answer. Others on this list just LOVE to have a bunch of header(Location: ) statements in their PHP code, so you are not alone. Just something to think about. :-) -- Like Music? http://l-i-e.com/artists.htm -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

Paul Thank you both! I did always use session_start() and finally I also already use the second option Paul addressed, in order to overcome the issues raised by header(). Not in the same terms, but the URL parameters was my idea too. So could I guess that this is there's no direct remedy to avoid header() delete sessions variables?:-) Alessandro -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
Re: [PHP] $_SESSION - Learning

Subject: [PHP] $_SESSION - Learning
Hi
I am finally starting to try and use register_globals = off on my Servers.
This means a lot of code that has to be checked and changed.
Unfortunatly I am struggeling to come to grips with this new concept (new
to
me that is) and was wondering if anybody could give me some pointers.
Getting stumped at my login script.
Once I have checked user and passwords, I pass a few SESSION vars to use
throughout my app.
snip
if ($status == 1)
{
//initiate a session
session_start();
//register session variables
$_SESSION['SESSION'];
//Get DataBase details and connect to it
include($root_path . include/vars.php);
$query = SELECT * FROM admin WHERE user_name = '$user';
$result = mysql_query($query);
$row = mysql_fetch_object($result);
//include the username
$_SESSION['SESSION_UNAME'] = $row-user;
//include the user id
$_SESSION['SESSION_UID'] = $row-admin_id;
//set the SecLevel Session Var
$_SESSION['SESSION_SEC'] = $row-sec_level;
//Now do the redirect
//redirect to Admin Page
header(Location: ./admin_main.php);
exit();
}
else
/snip
Where ever I have the $SESSION['var_name'] I used to have a
session_register(SESSION_VAR);
$SESSION_VAR = $row-user;
I then redirect to my app main page and check if a session is registerd to
make sure a user is logged in:
//check that each page is secure
session_start();
//OLD CODE IN SCRIPT = if (!session_is_registered(SESSION))
if(isset($_SESSION['SESSION']))
{
//if session check fails, invoke error handler
header(Location: ./../error.php?e=2);
exit();
}
?
That all works fine, but when I finaly start to display data on the main
page, nothing shows up.
One of the things I try to display is the name of the user logged in:
From the login script
//include the username
$_SESSION['SESSION_UNAME'] = $row-user;
then on my main page
echo logged in as b . $_SESSION['SESSION_UNAME'] . /b ;
Needless to say, no data is displayed. anybody able to point out what
I
am getting wrong here. It used to work fine before the old way with
register_globals = on.
SIDE Note:
On a Windows PC with Apache, PHP and MySQL installed, even with the
register_globals = on set, the SESSION vars do not work.
Thanks and sorry for the long post,
Ross

RE: [PHP] $_SESSION vs Database Call
The difference between the two probably works out to less than 10 milliseconds on most servers, from a quick study that I ran on some HP servers that were brand new last summer, with the faster times using the filesystem. Course, the flexibility gained in managing the database version caused us to ask, would any of our users notice a 10 millisecond difference in response? Answer was; only the paranoid would notice the difference ;-). Course our user population was relatively small (100 - 500 concurrently signed on).

Hmm .. I haven't been on the list for a while so it took me some time to answer ;).. Anyways, what I believe is a possible cause for your problem is that there simply ain't no session started. Maybe the always start session before the php page request setting was On if not configured, but is now Off in your ini file. 783 ; Initialize session on request startup. 784 session.auto_start = 0 Might wants to be changed to 783 ; Initialize session on request startup. 784 session.auto_start = 1 Also check this one 773 ; Whether to use cookies. 774 session.use_cookies = 1 In combination with 850 ; trans sid support is disabled by default. 851 ; Use of trans sid may risk your users security. 852 ; Use this option with caution. 853 ; - User may send URL contains active session ID 854 ; to other person via. email/irc/etc. 855 ; - URL that contains active session ID may be stored 856 ; in publically accessible computer. 857 ; - User may access your site with the same session ID 858 ; always using URL stored in browser's history or bookmarks. 859 session.use_trans_sid = 0 If both are set to 0, sessions simply won't work since PHP cannot know about the session id. If session.use_cookies is enabled, and session.use_trans_sid is not than you should have Cookies enabled in your browser for sessions to work. Or if you're on Windows, pay special attention to 771 session.save_path = /tmp Which should then be changed to smth like c:\temp That's pretty much what I can say about it ..

Re: [PHP] $_SESSION act funny...
If you go to the next webpage by using the same file (webpage) or a
$_SERVER['PHP_SELF'], the data in the $_SESSION array remain the same, it
does not change as it should.
snip
if ($_SESSION['test'] == one) { $_SESSION['test'] = two };
if ($_SESSION['test'] == two) { $_SESSION['test'] = three };
if ($_SESSION['test'] == three) { $_SESSION['test'] = four };
if ($_SESSION['test'] == four) { $_SESSION['test'] = one };
The code above will always result in $_SESSION['test'] == 'one', if you
start from any of the four tested values. Is there some other behavior you
are expecting?

Re: [PHP] $_SESSION act funny...
I'm kind of expecting them to change because using the hyperlink to go to
the next webpage should be treated as such for the same file (webpage file).
The reason I'm using the same file is because of the navigation menu with
all of the menu options that go to the include file...

Re: [PHP] $_SESSION act funny...
Oh Ha ha... I see what you meant.. The $_SESSION['test'] had already been
changed from one to two, then three, then four, then back to one. I didn't
see that coming.. I thought it just start at one and haven't changed at
all.
Thanks!!!

RE: [PHP] $_SESSION as $key=$value
Daniel,
Rather than sending them to a new page to validate the form and then
sending them back if a field is invalid, do the error checking from the
same script.
Here's an example, a bit simple but just to give you an idea.
For a better explanation, you should read this article which elaborates
on this method:

?php
if($HTTP_POST_VARS){

Re: [PHP] $_SESSION as $key=$value
Change error reporting in the php.ini to NOT include notices.
Echo out the variable
echo ( $_POST['fname'] );
All the notice is telling you is that $HTTP_POST_VARS['fname'] doesn't
exist, which it isn't if you haven't posted it to this page.

This is because when the form is first submitted, nothing has been
submitted, and thus $HTTP_POST_VARS['fname'] has no value. PHP is
simply warning you that you're trying to use an unitialized value.
Check the value first and you'll not have a problem with it:
?php
$output_fname = isset($_POST['fname']) ? $_POST['fname'] : '';
?
input name =fname type=text value=?php echo $output_fname ? /
If the first line looks odd, check out:
http://ca2.php.net/manual/en/language.expressions.php
You could just turn down your error reporting, but all that does is
hide from you the fact that you're using code with problems in it. You
should make sure the code executes in a development environment with
full error reporting on without warnings or notices, before you turn off
error display on the production box.

Hi Jochen, How can I process $_SESSION variables if the user disables cookies and session.use_trans_sid = 0 ? You could use a combination of outputbuffering and a self-written session-handler. So you could build a trans_sid-alike system, that would do more checks (i.e. compare IP-Addresses) to validate, if a session is really the one it is claiming. (Of course this would be slower as trans_sid's and ain't that easy to do) -Sascha -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
