[PHP] Session-variables
Is it ok to mail questions to this list? If so; Is there something similar like the "session variables" of ASP in PHP, or do one have to use (client-side) cookies instead? /thanks/me -- PHP General Mailing List (http://www.php.net/) To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED] To contact the list administrators, e-mail: [EMAIL PROTECTED]
[PHP] Session Variables
When does a session variable become available? Immediately after the
session_register command or after the script ends?
And if the commands are as follows:
session_start();
session_register("hello");
$hello=3;
will the session variable $hello be set to 3 or do I have to add another
session_register() call after changing the value?
Really appreciate any help,
Nikhil

[PHP] session variables
How can I change the values of session variables
(session_register('variable');) in a session. Do I just
unset($variable); and do session_register() again and give it a new
value. I tried this and it seems that it doesn't work.

[PHP] Session Variables
Hi There, I am a beginner to PHP and I am tring to use session variables on my site.

[PHP] Session Variables
I understand the concept of session variables, so I want to know the best
methodology of approaching this:
1) HTML redirect to PHP page
2) PHP page looks for session
a) If found, show some stuff
b) If not found, prompt user for username and password
3) If no session, prompt user for username and password, once entered & is
ok, set session and redirect
Following is a code snippet I borrowed that I think would work, correct me
if I'm wrong:
// Setting a name for our session.
session_name("hasLoggedIn");
// Starting Session.
session_start();
// Register vars into session
session_register("username");
// Setting values for session vars.
$HTTP_SESSION_VARS["username"]=$HTTP_POST_VARS["username"];
// Referring a session info to another PHP.
echo "text";
Thanx!!

[PHP] Session variables
I am designing a form using sessions in which the user inputs their details on page 1 and after submitting they are directed to page 2 for confirmation. They then have the option of editing their input (ie they are returned to page 1) where their previous input is reflected in the form fields by value ='' This works fine except if the input type is a drop down box, in which case the default is shown. Is there any way around this? How can I show the user their previous choice in these boxes? Any insights would be appreciated.

[PHP] Session Variables
Is there anyway to prevent session variables from being overwritten by a get string?
I'm wanting to use sessions for security/login, but I'm finding that I can bypass this
very easily. For example, I want to hide menu items based on security level, so I use
something like this:
if ($HTTP_SESSION_VARS["sess_auth"] > 2) { print "News
Editor"; };
which works, however, it can be bypassed if someone just enters the value in the url
like so:
http://secured.site.com/index.php?sess_auth=admin
is there any way around this using sessions? Is there a far more suitable method?
Thanks!

I am using a session to store a variable so when someone enters something into a field the persons username(which is stored in the session) is also entered into anoter field. The problem is that it only works the first time, so how can I make the session last for a required length of time, so that if the person leaves the site and returns without the login then the variable is still stored and entered into the field.

[PHP] Session variables
I'm not too clear on HTTP headers, cookies, and such. So here are questions related to that. Let's say I generate a random number that I want the user to enter in a form. When I generate the number, I store it in a session variable ($_SESSION). When the user submits the form, I check the number they enter with what I've stored in the session variable. 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.

[PHP] SESSION variables
I am programming a blog. index.php sets up the layout for the web page. This includes the heading, left hand and bottom menus. The content is loaded by the command: include($filename); the $_SESSION variables aren't available to files like blog.php . The session variables only work in the initial file, index.php. I am NOT using frames. The web page is loaded all at the same time. Simply when index.php is done, it passes the "baton" to the next .php file to display the specific information the user is requesting. Any ideas / suggestions?

[PHP] Session Variables
I have a quirky problem that should be a breeze for someone who is smarter
than I.
I have a script where I am registering a HTML form post variable as a
session variable and then echo it. In the real script I use it in a MySQL
query, but for the sake of this post, here is the "script":
$user1 = $HTTP_POST_VARS["user1"];
session_register("user1");
echo $HTTP_SESSION_VARS["user1"];
This doesn't work, however, if I hit the refresh button the var miraculously
appears!
What am I doing wrong?

No additional calls are needed. You will need to do session_start() on the
next page if you want to access $hello there.

Re: [PHP] Session Variables
Funnily - doesn't work for me. Here's what I got:
Script #1
#!/usr/local/bin/php
Script #2
#!/usr/local/bin/php
If I start script#1 (and it sleep()s), wait 10 seconds, then launch script
#2 in a separate browser window, script #2 returns empty. However once the
sleep() is completed and I refresh the window with script #2, the output is
okay (1).
Why does this happen?

RE: [PHP] Session Variables
The session variable values get stored to the session file (or database, or
wherever your configuration is set to store them) at the end of script 1.
When session_start() is called in script 2, those values get restored from
the session file. So, your results are expected: PHP needs to store the
session values from script 1 before they can be retrieved by script 2.

so the session variable is set only when the script ends? I thought you

RE: [PHP] Session Variables
Sorry for the confusion. The variable has a value as soon as you assign it, and you can use the variable in other statements within the same script. However, the value does not get stored to the session file until after the script ends.

What do you mean "don't work"... what are you trying to do?
page1.php
click to go to page 2
page2.php
The value of $_SESSION['today'] is .
This code assumes you either have trans-sid compiled OR are allowing cookies
on your browser AND cookies is a method that PHP sessions use (it is by
default) in php.ini.

RE: [PHP] Session Variables
I have a function that i call at the beginning of each page (well, those
that require user auth).
checkLogin()
this checks for a positive integer value in a session variable called
intUserID
$_SESSION['intUserID'];
is that isn't a positive integer, i redirect to the login page.
the login is split into two script, prompt and process. prompt is a form
which POSTs data to the process script which in turn verifys the
username/password and if valid, assigns $_SESSION['intUserID'] the value of
the users user ID.
all looks fine to me.

Subject: [PHP] Session variables
I am designing a form using sessions in which the user inputs their
details on page 1 and after submitting they are directed to page 2 for
confirmation. They then have the option of editing their input (ie they
are returned to page 1) where their previous input is reflected in the
form fields by
value =''
This works fine except if the input type is a drop down box, in which
case the default is shown. Is there any way around this? How
can I show the user their previous choice in these boxes?
Any insights would be appreciated.

PHP will do this automatically *if* you initialize your session variables to
*anything* as soon as you register them. For example,
session_register("sess_auth");
$sess_auth = "";
If you do this, then session variables will overwrite GET/POST variables,
and the latter will need to be retrieved from the $HTTP_(GET/POST)_VARS
arrays.
Another approach is to turn register_globals off in php.ini. This is a long
one to explain, but has been covered quite bit here- search the archive.

Note that session_register() will implicitly commence the
session, and thus will automatically instantiate all session
variables. Hence, the above two lines need to be reversed,
otherwise you might overwrite the session variable.

[PHP] session variables - help
I am asking a similar question to one I asked yesterday (which received no
answers) with more information in the hopes someone will be kind enough to
guide me.
I have an order form populated with an array (as opposed to a database
table). The user can enter quantities, and the form posts all the
information to the order_process page where the values they entered are
listed for review.
I decided I wanted to allow them to edit quantities before actually
submitting the form (by which I mean before using the mail() function).
I found that $_SESSION is the way to go.
On the order summary page (order_process.php), I start a session and I get
all the POST information via:
[code]
session_start();
extract($_POST);
[/code]
Instead of echoing the quantity values of each item, I populate an input
field with them within an echo:
[code]
//when this function is called, $a is a the quantity variable $show_01_qty
function writeResultRow($a, $b, $c, $d, $e, $f) {
if($a != '') {
echo "";
. . .
}
[/code]
Now, in order to update a quantity, the user replaces the quantity in the
input field with the new number, and clicks a submit button which posts to
order_update.php.
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.
Help please!

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?

Session data is stored on the server and tied to a browser using a cookie. The cookie contains a random string which uniquely identifies a session on the server. The session_start() function handles all the details of setting and maintaining that cookie and managing the server-side data. Cookies are transferred between client and server with every request in the headers. If you don't have Firefox getfirefox.com. The google for the livehttpheaders addon and install that. Turn it on and browse your site. You will see the cookies in the headers of both requests and responses. Cookies are not stored on the server side, they are sent by the client with each request. No additional HTTP requests are involved when using sessions. -Stuart -- http://stut.net/ -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
Re: [PHP] Session variables
Yeah i guess the cookie doesn't need to be stored on the server since it's in the header anyway. Thanks for clearing that up. Tim-Hinnerk Heuer http://www.ihostnz.com Charles M.

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?

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.

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.

I would strongly suggest using the $_SESSION variable, even if
register_globals is on, that way sessions work regardless of its
setting.
page 1:
session_start();
$test = $_SESSION['test'] = 'Hullo World';
echo $test;
page 2:
session_start();
$test = $_SESSION['test'];
echo $test;

[PHP] session variables in OOP....
Hi all, I'm busy building a site which uses OOP. Several classes are used to constuct different sections of the final page to be displayed. The overall class is called class.basepage.php This is the page which outputs HTML and calls other classes to construct other parts of the page. Now I have this problem: In one of the objects I use session variables. However i get the famous error :Cannot send session cookie - headers already sent by (output started " Is there a way to overcome this problem? I mean: the session variable is registered in the main part of the page after the class $this->header is called (which writes HTML)... now, I don't think I can register the sessionvariable at the top of my script since the value of the session var is determined in the main.class...or can I? I hope you understand my problem and have some tips for me. Below is some code snippets I'm using: thx and regards Wilbert Enserink class.basebape.php--- header(); ?>// includes a php file which writes HTMLcode functioning as the "header" of the HTML page (i.e. navigation menu) main(); ?> // includes a php file (main.php) which writes the main part of the HTML data --- ---main.php-- echo "a lot of HTML depending on queries and stuff"; session_register($variable); output browser-- Warning: Cannot send session cookie - headers already sent by (output started at /opt/guide/www.designmatcher.com/HTML/wwwtest/class.basepage.php:125) in /opt/guide/www.abc.com/HTML/wwwtest/phpincludes/main/main.php on line 400 - - Pas de Deux Van Mierisstraat 25 2526 NM Den Haag tel 070 4450855 fax 070 4450852 http://www.pdd.nl [EMAIL PROTECTED] -

[PHP] Session Variables and Redirecting
I've done this on other platforms ASP,Cold Fusion, but I need to know what's
the best way to do it on PHP.
1. grab username and password from POST vars.
2. select count(*) from users where username = '$username' and
password='$password'... something along these lines
3. if that user exists and password matches, set a flag on the user and send
them to the right page, otherwise increment failed attempts and send them
back to login page.
if (count > 0)
session_register("someflag");
$HTTP_SESSION_VARS["someflag"] = somevalue;
header("Location: secretpage.php");
}
else
session_register("failedattempts");
$HTTP_SESSION_VARS["failedattempts"]++;
header("Location: loginpage.php");
}
but apparently, i can't start/register a session and then redirect. Is
there a better way to do this?

Johnny

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:
[code = order_process.php]
$v) {
$_SESSION[$k]=$v;
}
$thisPage="AFY"; //NAVIGATION PURPOSES
include("afyshows.php"); //CONTAINS ARRAYS FOR SHOW ENTITIES; POPULATES
ORDER FORM
?>
. . .
. . .
\n\t";
echo "".$b."".$c."".$d."";
echo "".$e." =\$".$f."";
echo "";
}
}
//SETS $Total_show_01 to PRICE * QUANTITY
//FORMATS TOTAL
//IF A QUANTITY IS ENTERED, WRITES THE ROW WITH CURRENT VARIABLES
$Total_show_01 = findTotalCost($shows['show_01']['price'],
$_SESSION['show_01_qty']);
$Total_show_01_fmtd = number_format($Total_show_01, 2, '.', '');
writeResultRow($_SESSION['show_01_qty'], $shows['show_01']['title'],
$shows['show_01']['date'], $shows['show_01']['time'],
$shows['show_01']['price'],$Total_show_01_fmtd);
//ABOVE LINES REPEATED FOR ALL 38 ENTITIES (show_01 to show_38)
?>
. . .
[/code]
Now, here is the update_order.php code in entirety:
[code]
$val) {
if ($val == "0") {
unset($_SESSION[$var]);
} elseif ($val == '') {
unset($_SESSION[$var]);
} else {
$val = $_SESSION[$var];
}
}
header("Location: order_process.php");
//NOTICE I FIXED THE LOCATION OF THE header() FUNCTION
//BUT IT STILL DOES NOT UPDATE
?>
[/code]
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
appreciated.

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.

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]);
endfor;

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.

No, wait a minute, hold your foot up! I was so focussed on the strange
assignment that I didn't read the whole thing properly. What you're *actually*
doing here is -- er, well, totally not what you want to, I suspect! Having
re-read the message I responded to, I'm going to go back to it and post another
response

Er wait, no! Sessions and hidden form fields are generally alternative
solutions to the same problem -- you shouldn't be putting the same values both
in the session and in hidden form fields. In this case, I'm beginning to
suspect that the hidden fields are the better solution, but there is a certain
amount of personal preference in this.

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.

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.

[PHP] session variables in tmp
trying out a CentOS release 5.2 (Final) V4_1_0 on AWS. Was working fine and now it seems that php has stopped writing any session variable to /tmp. I was cleaning up the user table in mysql and limiting permissions. Not sure that this would have anything to do with it. Restarted apache/mysql. tmp is set to drwxrwxrwt 4 root root 4096 Jun 5 00:46 tmp PHP 5.2.4 MySQL 5.0.45 any thought on where else to look.

If you're not telling PHP (in php.ini) to auto-start the session, then you'll need session_start() before accessing $_SESSION. If you're certain the session is being properly instantiated in the code, make sure that the user as which the web server (Apache, et al) is running has permission and available disk space to access the session storage media (file system such as /tmp, database table, et cetera). -- Network Infrastructure Manager http://www.php.net/ -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
