Hi Stephen, you can try setting the session path using session_save_path http://www.php.net/manual/en/function.session-save-path.php.

Thanks Gerardo. I send a large dump.sql file to my /tmp dir and filled up the remaining space so PHP was not able to write any more session variable. Took me a little while to figure that one out.

Re: [PHP] session variables and SVG documents
Hello,
unfortunately, it does not suite my needs. The image must be clickable. The
application I'm developping reads data from a database and display the
information graphically. The user must be able to click on some elements of
the picture, and I have to store the information the user clicked on
(session vars). I cannot tell the user not to use IE, so I have to find
another solution...

well under Firefox, as well as IE with ASV:

It appears IE does not support svg yet and you need a plugin for it.
However, you could also design your code differently by using Imagemagick
to convert the svg to png.

IE doesn't display SVG natively, and the plugins for it are pants.
However, IE does make use of its own propitiatory vector language called
VML, This is how the Cufon font replacer system works.

It sounds like it's the SVG plugin you're using on IE that's badly
misbehaving. That said, I've not seen any plugins that correctly pass
across the full headers that the browser would. I tried using sessions
once to secure media files by checking for a valid login against the
session id, but the plugins requesting the video clips didn't send any
cookie data in the header request. As such, it might be better to not
rely on it in this case.

RE: [PHP] SESSION VARIABLES ACROSS DIFFERENT WINDOWS/TABS
Hi Jamie. Thanks. Good info. I knew something changed somewhere. This works like a charm in IE8..never saw the New Session option under file...me bad !! Greetings. -Original Message- From: Jaime Bozza [mailto:jbo...@mindsites.com] Sent: 20 August 2009 09:49 PM To: Leon du Plessis; 'Floyd Resler' Cc: a...@dotcontent.net; php-general@lists.php.net Subject: RE: [PHP] SESSION VARIABLES ACROSS DIFFERENT WINDOWS/TABS Leon, This is really just a function of the browser. When a session cookie is created, if the browser is setup for a single instance, that's the session cookie it'll use for *any* request to that domain. This functions differently depending on what browser you're using. For example: Firefox - All windows, tabs, etc, under the same profile will use the same session. If you create profiles, you can have different sessions. IE7, IE6 - All tabs or windows opened from clicks will share the same instance/session. Starting IE from the icon will open up a new instance/session. This worked great if you wanted to run two different sessions at the same site/domain. Just start IE up from the icon again and you'd have a new session. IE8 - IE8 model changed, so that all browser windows, tabs, etc., run under the same frame/session, much like Firefox. Clicking the IE icon again now just keeps the same frame and thus the same session. Originally, this sounded like a big problem, but IE8 introduced a new feature - File Menu - New Session. This will open up a new window that will be a separate frame that will not use current session cookies. Here's just one of many links, but gives some helpful hints on the IE side: http://blogs.msdn.com/ie/archive/2009/05/06/session-cookies-sessionstorage-a nd-ie8.aspx And another: http://blogs.msdn.com/askie/archive/2009/05/08/session-management-within-int ernet-explorer-8-0.aspx One of the issues now is that if you close IE, your session does not disappear. In the past (IE7/IE6), your session would disappear if you closed a browser window that you opened yourself, but it *wouldn't* disappear if you closed a browser window that was opened by a click from Outlook or another program. This was a bit inconsistent. I won't argue whether or not their fix was the best way to go, but now it's at least consistent. Note - In Firefox, not even Private Browsing separates the session cookies. If you start Private Browsing (Firefox 3.5), log into a site, then start a new browser window from the icon (that isn't in Private Browsing mode), it shares the session cookies. (Before you ask, I just checked this to be sure.) IE8 InPrivate Mode is a totally separate session, cookies and all. This could possibly be another way for you to run multiple sessions against the same domain. OTOH, multiple InPrivate sessions running at the same time share the same frame, so they share the same session, so it would only be good for a single new session. If you need more, just use File - New Session.

If I work with my company account, then my personal account must not become an issue because I am on the same machine and site. I have no issue with using FF and IE to do testing as that takes care of browser compatibility testing at the same time :-), but I think when you start a new session with new values, it should be kept under that window/tab alone. Cookies can take care of more details, but my opinion is data should never be affected across windows/tabs unless the same user is logged in on botheven then I would expect PHP to keep data per session. Maybe it goes beyond being an IE or FF issue..the questiojn is...will PHP allow variables from session A become corrupted when session B is in progress when they should actually be handled seperately?

Thus when having the same web-site open and using SESSION variables but for different users, Internet explorer can become disorientated. This also sometimes happen when I have two separate browsing windows open with Internet Explorer for the same site. I have yet to determine if this is an internet explorer, or PHP or combination of the two that is causing this condition. To my understanding _SESSION variables should be maintained per session, tab or window. If this has been addressed already, my apologies, but thought it worthwhile to mention. If someone perhaps have a solution or can confirm this as a known issue and maybe is the same or related to Angelo's problem?

Re: [PHP] session variables - help
I'm realy sorry for u, but the reason for no answers is ur concept.
may be some rules will help u and I recommend u to think to spend the time
to rewrite the whole code. Im shure u will solve the problem then:
first dont use the global arrays directly. pick the values u need and put
them in reasonable types of variables.
build the business logic on these variables and if u feel like put the
results in well readable new ones
then populate the presentation in the required htmls
this will give u an more structured code, easier to debug and more fun for
the group to help u
I still dont understand why u use the $_SESSION variable. user often leave
forms open for hours and then submit them. u can not expect a user to end a
job in the livecycle of the session. thats what hidden form fields are made
for.
the $_session is for member like things and applications with security
issues where u can expect the user to finish things in a certain time or u
restart the whole.

Ben,
First of all, I thank you for your time and help.
My ai with using unset($var) in update_order.php is to set the SESSION
variable for an item to ' ' (empty) so that it would not show up on the
order summary (because my writeResultRow() function will only write a row
if
that variable is greater than 0).
I just can't figure out what I'm missing here. Before I received your
response, I made a few changes to my code, which helped streamline the
calculating parts (grabbing values from SESSION instead of POST, and now
when I update order_summary, the values will remain because it pulls them
from the SESSION).
I want to edit the values in the SESSION, so that when update_order.php
redirects to order_process.php, the values are changed, and if applicable,
an item is removed from the html table (if the quantity is less than 1).
Here is some more complete code:
[code = order_process.php]
?php

}
}
header(Location: order_process.php);
//NOTICE I FIXED THE LOCATION OF THE header() FUNCTION

If you're still with me, I thank you. I removed all the styling elements
from the html to make it easier for you (and me) to see what it says. I
have
invested many hours into this, and have generated many many lines of code,
but I hope what I gave you is sufficient, while not being overwhelming at
this hour.
Thank you very much for your help thus far, anything else would be greatly

This has just destroyed anything that was previously in the session, so if
you're recycling from the update_order.php script, you've just thrown away
whatever that script did! You need to make this conditional on having arrived
here from the initial form -- various ways you could do that, but I leave you
to figure that one out.
(Also, personally, if I were doing this at all, I would just copy the array as
a single entity:
$_SESSION['_POST'] = $_POST;
and then reference individual elements through that as, e.g.,
$_SESSION['_POST']['School']. That's probably a matter of personal style as
much as anything, but gives you another way to think about.)

AARRRGHHH!!
This cries out for an array-based solution -- repeating near-identical code
that many times is totally ludicrous, and should be a major clue that you need
to refactor. You'll have to forgo using indexes like ['show_01'] and use
straight integers, but the massive reduction in repetitive code (and hence far
fewer opportunities for mistakes!) will be well worth it.
Something like:
for ($i=1; $i=38; ++$i):
$Total[$i] = findTotalCost($shows[$i]['price'], $_SESSION['qty'][$i]);
$Total_fmtd[$i] = number_format($Total[$i], 2, '.', '');
writeResultRow($_SESSION['qty'][$i], $shows[$i]['title'],
$shows[$i]['date'], $shows[$i]['time'], $shows[$i]['price'],$Total_fmtd[$i]);

That line is back-to-front -- you're assigning the current value in the session
to $val, which is then immediately thrown away as the foreach loop starts a new
iteration. What you mean is $_SESSION[$var] = $val.

If I'm reading what you want to do correctly, it seems to me there are two
obvious approaches to this:
(i) Have a single form which posts back to itself, showing all the show
information and requested quantities and calculated result fields (such as
total cost); initially, this will have the calculated fields not displaying
anything, and these will be (re)populated at each Update. Using this method,
all your values are contained solely within the $_POST array.
(ii) Have your initial form post to the process form, which then also posts to
itself on Update. This process form will have visible fields only for values
which can be changed, but *must* then contain hidden fields for all the other
values which were originally passed in the $_POST array. This arrangement
means that the process form always receives a full complement of values in the
$_POST array -- either from the original form, or from hidden fields posted
back to itself.
This is all just coming off the top of my head, and I'm sure there are
improvements/other solutions to be offered. Hope this will give you some
things to think about, and maybe a pointer or two towards a satisfactory
solution.
Cheers!

Re: [PHP] session variables - help
Thank you all for your responses.
Mike.
I like the ii option better, mostly because I already have most of that in
place (ie. order posts to process, and process has editable fields and
hidden fields with the remaining complimentary values).
Martin suggested I use the following code for my update script (which is
posted to via the process page):
[code]
foreach($_POST as $key = $value)
if( '0' == $value || '' == $value )
{
/*if*/ session_is_registered( $key )
session_unregister( $key );
}
[/code]
I am not following the logic on the above code very well, but is this indeed
a better option? And is not session_*whatever deprecated? The reason I am
using $_SESSION is because it seems that php 6 will use solely this method,
and it currently works with php 5. The other reason I am using it is so that
I can keep the variables stored elsewhere for whenever I need them; I don't
want to have to juggle all the information with POST and hidden inputs
unless it will work seamlessly, and be ready for update at a later date (if
I move to using a database to store show information, or when php 6 is
mainstream).
Keep in mind that once I get the update feature working, I need the process
page to have a final submit button that will insert the order into a
database table AND send a notification email to myself (and an email to the
user). Am I setting myself up for failure with this udate order option? I
ask because the update feature relies on a form, and are not forms limited
to one submit button?
Thanks all for your patience! I will work on this today and write back with
any further questions I can't figure out on my own. And if anyone has any
advice I will be checking my email regularly.

Thanks all for your patience! I will work on this today and write back with any further questions I can't figure out on my own. And if anyone has any advice I will be checking my email regularly. If you've already tried this with no luck, please ignore -- but you might speed up the whole process by stepping aside from the real code briefly, starting fresh in an empty directory, and just putting together a handful of extremely simple scripts with the single goal of entering one value, updating it, and then doing some final pseudo-processing on the updated value. Then, you could step it up a bit by by adding a second value that gets entered at the beginning, and cannot be updated in the middle but must be preserved through to the end. Doing all this might help clarify the basic flow of the system and enable you to simplify its structure before going back and tackling the real code.

Re: [PHP] session variables - help RESOLVED
Thanks everyone for your help, I finally got it working. For those that were curious, my writeResultRow() function was not naming the input fields properly, so the SESSION variables could not be updated properly. I had to add an array item for each show, an id, then call the id to name the inputs with.

Re: [PHP] session variables - help
I have the following code for order_update.php:
[code]
session_start();
extract($_POST);
foreach ($_POST as $var = $val) {
if ($val 0) {
$_SESSION[$var] = $val;
} else {
unset($var);
}
header(Location: order_process.php);
}
[/code]
This is not working, however, and it just loads order_process.php with no
values for the varaibles, as if I just refreshed the page with no sessions.
Maybe you left it out but I didn't see any place where you used $_SESSION in
order_process.php. Also, your redirect in order_update.php appears to be
inside your foreach loop, which would definitely mess things right up -- but
maybe that was just a typo in your email?
Otherwise the logic in order_update.php looks OK, but there are a few side
notes that jumped out:
1. I'm not seeing why you used extract($_POST) in order_update.php. Right
after the extract() call, you iterate through $_POST with a foreach loop, so
what's the purpose of calling extract()? Is there more code that you left
out?
2. Calling extract($_POST) is dangerous. The PHP manual warns against it,
although without giving much of an explanation:
http://us2.php.net/manual/en/function.extract.php
Apart from making it difficult to filter the input you're expecting to see,
extract($_POST) also allows a malicious end-user to define any variable of
his choosing and to overwrite any variables that you may have defined in the
script before the extract() call.
I like to use filter_input() to read the values of POST variables.
By much the same token, you'll want to escape $a, etc., in your
writeResultRow() function, with something like htmlentities().
3. Why the unset($var) in order_update.php? $var already gets reset each
time foreach iterates. So, calling unset() on it at the end of the loop
doesn't really do much. I'm wondering what you were aiming at there.
Thanks,
Ben
Re: [PHP] session variables - help
Ben,
First of all, I thank you for your time and help.
My ai with using unset($var) in update_order.php is to set the SESSION
variable for an item to ' ' (empty) so that it would not show up on the
order summary (because my writeResultRow() function will only write a row if
that variable is greater than 0).
I just can't figure out what I'm missing here. Before I received your
response, I made a few changes to my code, which helped streamline the
calculating parts (grabbing values from SESSION instead of POST, and now
when I update order_summary, the values will remain because it pulls them
from the SESSION).
I want to edit the values in the SESSION, so that when update_order.php
redirects to order_process.php, the values are changed, and if applicable,
an item is removed from the html table (if the quantity is less than 1).
Here is some more complete code:

Since this session variable survives across page loads (assuming session_start() is appropriately called), how is it stored and recalled? Is it automatically stored as a cookie on the user's system? Or is it stored on the server? And how does a server get a cookie? Is it a separate request made by the server to the client? If the value I've asked the user for is *not* stored as a cookie, then is it passed as part of the HTTP submission or what? Thanks for any enlightenment on this. Paul -- Paul M.

Re: [PHP] Session variables
The session data is stored on the server. In the user's browser, only a session cookie is stored, usually a random session id string. I could never retrieve the session variables with any browser tools, always only with PHP by echoing them out or something. Also, a cookie is simply a text file with a maximum of 4096 characters on the user's browser, not enough to store big session variables with big objects. So, the user's browser just stores a cookie with the session id, so that the server knows which user to map to which session variables. The session variables (in PHP) are stored in the temporary directory on the server in a text file (flattened or serialized), where the server can retrieve them across requests. This is important for security reasons. You might not want the user to be able to view certain variables in their browser otherwise they could change them and cause some damage, e.g. imagine a user has a permission level between 1 and 10 and 1 is the super user. You can store this level in a session variable, and the user cannot change it. If they could, it would be a disaster! Also, if one could store more than 4096 characters, it would be relatively easy to write out some session variables in order to flood the browser memory and make it crash or even worse. Oh, and the Cookies, as far as i know, are always sent in the http headers. They are stored on both client and server and can be set on both sides, with javascript or server side code (php). So they can only be checked in every request by the server side code, and while javascript is being executed on the client. Please correct me if I'm wrong because I would need to review a lot of code in which it is assumed that session variables are NOT stored on the user's machine. Makes sense?

Re: [PHP] SESSION variables
This is one of the first commands given. I am using modrewrites to call the blog entries. blog.php is responsible for displaying both the table of contents and the blog entries. When the table of contents is called (http://www.rons-home.net/page/blog/ ) the session variables are present. When an actual blog entry is displayed ( http://www.rons-home.net/blog/28/ ) the session variables aren't there. I am not sure what is happening / why. The login is at http://www.rons-home.net/page/login/ It has 'page' in the URL. But I am not sure why this should upset the session variables ... Any thoughts?

That's not true, since he's using user data in the SQL statement. The query method has nothing to do with whether data should be escaped. Of course, addslashes() is sort of a last result with regard to escaping data for use in a query. The more preferable options are those native to the database you're using, if they exist.

Re: [PHP] Session Variables ~ Best Practices
I presume I am right in assuming that I can declare variables anywhere I like providing I have started a session on the page but I cannot actually use those variables until a post or some similar action has been performed by the user. No, you can use them right away - they are stored server-side, so you don't need to wait for a request/response loop before reading them: session_start(); $_SESSION['foo'] = 'bar'; echo $_SESSION['foo']; // 'foo' is available immediately No need to perform any special declarations. It's cookies that need to wait for a subsequent request to be available via getcookie(). Careful with your session variable naming - you may want to implement a primitive namespace, by using named arrays in $_SESSION, such as $_SESSION['auth']['username'] or $_SESSION['prefs']['boxers_or_briefs']. -mike. - michal migurski- contact info and pgp key: sf/cahttp://mike.teczno.com/contact.html -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

I am also wondering if I need to declare all my variables one after the other or can I simply declare variables that I will be using immediately upon submission. I'm not quite sure what your question is, but here's some info. You have to call session_start() before using anything in the session. This must be called before there is any output to the browser. After the call to session_start() you can get/set/unset any session value you want at any time in the script (all of this is stored on the server). The best way to do all of this is through the $_SESSION superglobal. Use it like a normal assicative array: $_SESSION['var'] = 'value'; or: $_SESSION['array'] = array(1, 2, 3, 4); os: $_SESSION['object'] = new Object(); Everything you put in there will be available from any function without having to use the global keyword or the $GLOBALS superglobal. Note that you can't store recources in the session (at least, they can't be used as resources on subsequent requests.)

Just make sure you call session_start() before you access the $_SESSION array. Let's say I have two users, first one logged in, using ronald as username, while user ronald is still logged-in User nhadie also logged-in from somewhere, will the value of $username of user ronald be changed to nhadie? No, with sessions there will essentially be multiple values for the variables, one for each session. When a user requests a page their session id will be used to set the correct values in the $_SESSION array. For example, when ronald loads the page $_SESSION['username'] will be ronald. When nhadie loads the page the $_SESSION['username'] variable will be nahdie. -- Adam Bregenzer [EMAIL PROTECTED] http://adam.bregenzer.net/ -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

Re: [PHP] session variables
--- Diana Castillo [EMAIL PROTECTED] wrote: If you store session variables , but the user has session cookies disabled, is there any way to recuperate those session variables? Cookies come in two types: session cookies and persistent cookies. Session cookies have no set expiration date, so they expire as soon as the browser session ends. Persistent cookies don't expire until the date indicated, and this often involves persisting them in a file (cookies.txt, for example). So, I think you just mean to ask how to make sessions work when the user has disabled cookies. Cookies are only used to propagate the session identifier, so you don't lose session data. At worst, you would just be unable to identify the user on the next request. PHP handles this last potential problem for you with the session.use_trans_sid php.ini directive. This will rewrite your URLs (in links and such) to include the session identifier, and PHP will automatically check both for the bookie and the URL variable. So, you will probably not need to do anything special. Hope that helps.

RE: [PHP] SESSION variables losing data on WinXP?
Knew I forgot to mention something. No, register_globals are off. Using
$_SESSION[] variables. I am logging in first. I log in fine, its when I
try to go to another page via a link on the entry page that I get booted
back to the login page. My scripts work fine on a Unix server, which is
what I reluctantly had to go back to using as this projects deadline is
too close not to do so. Its just on my computer locally that this does
not work. Code is below, it is fairly long.
Example Code:
//validation.php
include_once 'db.php';
include_once 'common.php'
session_start();
$uname = isset($_POST['username']) ? $_POST['username'] :
$_SESSION['username'];
$pwd = isset($_POST['password']) ? $_POST['password'] :
$_SESSION['password'];
if(!isset($uname))
{
header(Location: login.php);
exit;
}
$_SESSION['username'] = $uname;
$_SESSION['password'] = $pwd;
dbConnect(db);
$sql = SELECT * FROM admin WHERE
admin_uname = '$uname' AND admin_pword = PASSWORD('$pwd');
$result = mysql_query($sql);
if (!$result) {
error('A database error occurred while checking your login
details.\\nIf this error persists, please contact
[EMAIL PROTECTED]');
}
while($row = mysql_fetch_array($result))
{
$admin_id = $row['admin_id'];
}
$_SESSION['aid'] = $admin_id;
if (mysql_num_rows($result) == 0) {
unset($_SESSION['username']);
unset($_SESSION['password']);
header(Location:login.php?item=badlogin);
exit;
}
___
//login.php
... this is an html page with the login form. When submitted it goes to
index.php.
___
//index.php
include('validation.php');
if(!$_SESSION['aid'])
{
header(Location:login.php);
exit;
}
rest of page is HTML with a php include for the navigation
___
//nav.php
.a href=admin_signup.phpAdd Admin/a
___
//admin_signup.php
include('validation.php');
if(!$_SESSION['aid'])
{
header(Location:admin_login.php);
exit;
}
rest of page is HTML with a form that goes to add_admin.php for
validation and submission to the database. Its when I try to go to this
page via the link that I get sent back to the login page.

Re: [PHP] SESSION variables losing data on WinXP?
Speaking of your problem, you're using the header() function to exit the
webpage to the login page. So, it all come down to the either one of these
two or both of these two
if(!isset($uname)) {
if (mysql_num_rows($result) == 0) {
Upon closer inspection on the script, it look like either the $_POST['***']
wasn't returning data or the $_SESSION['***'] doesn't have data in it that
tripped the header() function. So, I'll take the assumption that the
$_POST['***'] does work as it alway does. So, it narrow down to
$_SESSION['***'].
Since you mentioned that you use it on both Unix and Windows. So, most
likely it all narrow down to php.ini. Can you check to verify that the
filepath is correct for Windows and that there is no issue with file
permission. Here's what I have that work for me on Windows 2000.

Re: [PHP] Session Variables in a Class
Thanks Curt,
You were absolutely correct. Removing the
session_register() lines before the $_SESSION[] fixed
the problem. By mixing the two before, it actually
would register the variable so I could later test for
the registered session variable but it did not retain
the value I assigned it. Thanks again for the help.

You might want to read
http://php.net/session
You are most likley running into a register_globals
issue.
A couple things to note:
. You must not mix $_SESSION[] access with
session_register()
anywhere in your script.
. When you issue session_register('name') inside
your class it is
declaring the global var $name as a session var,
not the $name in
your script.

Re: [PHP] Session Variables in a Class

Here's my class. I start the session in the
constructor and in later methods attempt to register
session variables. You can see I've tried a couple
different methods but none of them maintain the
session variable values. Any suggestions?
Is register_globals ON or OFF? You shouldn't mix session_register() with
$_SESSION. Just use one other the other, but I recommend just using
$_SESSION.
$_SESSION['var'] = 'some value';
to set a session var, and
if(isset($_SESSION['var']))
to see if a variable is set.
Also, if you have a varible $foobar within a class method that you define as
a session var, you must make it global if you want to access it in other
methods. The same thing for HTTP_SESSION_VARS. I think you're just running
into a scope issue.

You have to include the class-definition _before_ you start the session.

I've been experimenting with sessions. I can make

when I
create a class and try to define a session
variable
within a method in the class it won't work. I've
tried setting the session variable directly
($_SESSION['name']='somevalue') but that didn't
work.
The normal way of setting it -
session_start();
session_register('name');
$name='somevalue';
- didn't work either (within the class).
didn't work isn't very helpful to us. How useful
would it be for me to
just answer you with it worked for me.
Show us some code examples (short ones) as to how
this doesn't work, please.

Hi everyone,

You might want to read
http://php.net/session
You are most likley running into a register_globals issue.
A couple things to note:
. You must not mix $_SESSION[] access with session_register()
anywhere in your script.
. When you issue session_register('name') inside your class it is
declaring the global var $name as a session var, not the $name in
your script.
