[PHP-DB] session variables when accessing the same page
Working with storing and reusing session variables.
If I use t1.php to generate a form, and the form
calls t2.php, the session vars are available.
If upgrade t1.php to recognize if it is the first
time it has been called versus the second time
e.g.
if (isset($some_session_var)) {
generate_second_page();
} else {
# set $some_sesson_var in the function
# and use session_register() for that var.
# I have verified that I'm using "global $some_session_var"
# under here as well as generate_second_page().
generate_initial_page();
};
Under this scenario, I'm unable to find any session
vars. That is, "$some_session_var" is never set the
second time I call t1.php. If I change the tag
to call t2.php that has the code for 'generate_second_page()'
than all seems to work ok. Am I missing something?

This is pretty off-topic for the PHP-DB list. It should be on PHP-General
instead.
If I recall correctly, the actual session files aren't deleted on the server
when you call session_destroy(); They hang around until garbage collection
kicks in. The user's cookie is also not deleted so they come back with the
same session next time if the browser isn't quit first. One solution is to
manually unset the session variables as well. I've done things like this:
session_start();
session_unregister('this_password');
session_unregister('this_username');
session_unset();
session_destroy();
According to php.net, you should also do:
$_SESSION = array();
Before the calls to unset and destroy.
See the comments on this page for a bunch more information:

[PHP-DB] Session variables
I am using session variables throughout an application, and every time I try to log in as someone else after the first time I've logged in, it uses the userid of the first person that logged in. I know the session has to be destroyed or something, so I wanted to make a logoff page, but it is not working. I'm getting an Internal Server Error. Here is my code for logoff.php: Does anyone know what I am doing wrong? Thank you, Alexa
RE: [PHP-DB] Session variables when global variables switched off [Sorry, firs t message accidentally fired off to quickly ]
Try changing your code to
if ($_SESSION['verified'] != "yes"){
I think that's the problem

[Sorry, firs t message accidentally fired off to quickly ]
[sorry for the incomplete posting of a couple moments ago. I hit ctl
something or other and outlook fired off the e-mail against my wishes!]
I am making a section on a web site which requires that visitors log-in.
Log-in, password, etc are in an MySQL table. I am using (via a web host) PHP
4.2.2 with global variables turned off. Until now, I have worked with a
different host in which global variables were switched on.
The way it works
The user logs in at index.php. When she does so successfully, index.php
returns a menu of links. However, if she clicks on any of those links, which
are different pages, she gets a please log-in first message because each
page includes...
if ($_SESSION['verified'] <> "yes"){
echo "Please log in first";
exit();
}
Returning to index.php requires a log-in again.
So, it seems the session variable is not being sent being sent between
pages, although it works within the same page. I expect I am missing
something obvious. I've made this kind of thing work with global variables
on - so I assume I am misunderstanding something related to lack of global
variables.
I use
session_start();
at the top of all pages and
session_register($_SESSION['okbabe']);
on index.php.
Your enlightenment will be highly appreciated.

Hi Jeff
Don't use session_register() just use the $_SESSION superglobal as you would
use any other array.
So does this work?

RE: [PHP-DB] Session variables and arrays
After a little more research I found out strlen will return 5 for a real
array too, so throw that out. However, since gettype prints a string not
an array, I just don't know. print_r prints the array, but you can iterate
through it.
Do you do this before your loop?
reset($_SESSION['categories']);
print_r($var) will set the pointer to the end of the array, so you have to
reset it to the beginning before you iterate through it again.
Maybe this is the problem?

Try this after that print:
print is_array($_SESSION['categories']);
You should get a 1 -- if you don't, try this:
print gettype($_SESSION['categories']);
You should get "array" but if you don't, there is something strange going
on! If you get "string" though, do this:
print strlen($_SESSION['categories']);
If you get "5", then the variable might be a string with the contents
being the word "Array". Pretty doubtful, but we're being thorough here.

RE: [PHP-DB] Session variables and arrays
Ok. The categories are coming from checkboxes, e.g.:
Accountant
Which then are handled by a $cgi class dealy and handed to the
$_SESSION['categories'] variable before being forwarded to the next
step. I was thinking that the problem might be with the $cgi object, but
when I print_r($_SESSION['categories']) it shows the contents of the
array.
Anyways, I did the print ":::{$_SESSION['categories']}:::"; and got

Re: [PHP-DB] Session variables and arrays
Well, can't say I see the same problem:
"bye");
print_r($_SESSION['foo']);
echo "\n\n";
print is_array($_SESSION['foo']);
Outputs:
X-Powered-By: PHP/4.2.2
Content-type: text/html
Array
(
[hi] => bye
)
1
Which is what I'd expect it to show.
Now how did you assign categories?
Maybe the var is a scalar and is actually "Array (\n [0] => '1';\n [1] =>
'12';" and you are confused.o
If you are saying:
$_SESSION['categories'] = "Array (
[0] = '1';
";
Then it IS a scalar. Try this:
print ":::{$_SESSION['categories']}:::";
If you get this:
:::Array:::
Then I have no clue what the problem is
If you don't get that, then we know what your problem is.

[PHP-DB] Session variables and arrays
I'm having a problem with session variables and arrays. I'm building a multi step sign up form and I need to store all the variable until the final step, when they are inputed to a database. I thought the best way to do this would be to store the contents for $HTTP_POST_VARS in session variables. This works fine for everything except for my array of checkboxes. When I do a print_r($_SESSION) it displays the following for the sessionvariable assigned to the checkboxes: [categories] => Array ( [0] => '1'; [1] => '12'; ... Etc ... But when I run any sort of array function (is_array, foreach) on $_SESSION['categories'] it appears that it is a scalar, not an array. Any ideas? - Ryan -- PHP Database Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
[PHP-DB] session variables and form
hello all.. in my site, where im using phpscript, some users are allowed to del/modify contents of the database. for this they have been provided login name and password, after user loggs into the secure area, session starts. since here, user can modify/del contents of database, i needed to use many forms. arrays are used to store the checkbox, textbox values which user wants to modify. since these values are submitted thru forms in session, when browsers back button is pressed, it forces to press refresh button, to retrieve the values. can anyone help me to know how to pass variables to other pages in session using FORM POST or is it efficient to use session variables for all these values submited via FORM?? smita _ Chat with friends online, try MSN Messenger: http://messenger.msn.com -- PHP Database Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
Re: [PHP-DB] session variables across several pages
huh.. seems to work, now.
I do the following:
session_start();
session_register("form_data");
if($doAction) {
switch($doAction) {
case "Save Information":
// save data in cookies
$HTTP_SESSION_VARS['form_data'] =
array($name,$employer,$e_address);
...
and on the thanks page:
session_start();
session_register("form_data");
list($name,$employer,$e_address) = $form_data;
and it displays the correct data now.
S the trick seems to be to not use the same var names.
Ok. I got it.
Thanks!!

RE: [PHP-DB] session variables across several pages
i would consider trying changing the variable names - so the field on the
form would be called "address", therefore the variable passed through would
be $address, and then have the session variable called "sess_address" or
something like that, and then do
$HTTP_SESSION_VARS['sess_address']=$address;
see if that makes any difference?

This is freaky.
If I change the I can see the e_address coming in
correctly, but it gets changed back to old value -- by the
session_register('e_address')??
should I have something along the line of
if(!$e_address) register_session('e_address');
???

Re: [PHP-DB] session variables across several pages
I believe you.. I added
$HTTP_SESSION_VARS['e_address'] = $e_address;
in my process form code and it's still not updating the var.
snippit from select_class.php where I have reference to $e_address:
session_register("e_address");
...
switch($doAction) {
case "Save Information":
// save data in cookies
$HTTP_SESSION_VARS['e_address'] = $e_address;
die($e_address);
...
Employer Address:
...
entering any new data does not replace the old data as the
die($e_address) shows.
Whatsupwiththat???

You need to look up $HTTP_SESSION_VARS['name'] - that's how to change the
variables when they are already set..
i think most people have this problem when they first use sessions!

Subject: [PHP-DB] session variables across several pages
First, forgive me if this seems to be cross post -- but it does involve
both PHP and MySQL.
My client requirements are:
From their website, they display a list of classes. On registering for a
class, the user is sent to a secure page that is hosted on a different
secured server that does not have access to the client's MySQL database.
I pass in the class info so the registration form can display
"Registering for class $title$start_date$cost"
The form then gathers name, address, etc including credit card info.
On submitting the form, the data is processed and a PGP email is sent
out to the registar.
Then a thank you page is displayed and the user is forwarded back to the
main site, where a second page is displayed allowing for either download
of class materials or to return to the class list. This page is where I
post the necessary info into the MySQL database.
So my dilemma -- I want to use session_register to capture the field
info from the registration form and then read it back out on the website
thank you page.
I have
session_start();
session_register("start_date");
session_register("end_date");
session_register("section");
session_register("class");
session_register("title");
session_register("class_id");
session_register("register_id");
session_register("name");
session_register("employer");
session_register("e_address");
session_register("e_city");
session_register("e_state");
session_register("e_zip");
at the beginning of the form page (select_class.php) and the thank you
page on their website (thanks.php) where I post the info to MySQL.
The form includes inputs such as
Name:
What happens is that old data shows up for name, and address (the only
fields I have tested so far) regardless of what I enter in the form. I
was under the impression that a registered variable is updated once the
page is processed. If I am calling the same page (select_class.php) to
process the form, does the data get reverted somehow? The data just
doesn't seem to get updated to the form inputs.
What might I be missing?
Thanks in advance

[PHP-DB] Session variables
I have compiled php-4.0.6 from source with --enable-track-vars and
--enable-trans-sid options (--with-mysql and --with-apxs).
I use RH7.1 and mysql-3.23.41.
In my /usr/local/test/connect.inc I use the following code
This file is invoked in all my script files. (The system works without
session variables.)
In my login file (main.html) I do a
");
print("");
print ("");
print("");
?>
--
In my login.html script file I start the links to other database
utilities, where the /usr/local/test/connect.inc file is invoked.
When I run main.html, I get the following error message :
Warning : Cannot send session cookie - headers already sent by (output
started at /var/www/html/main.html: 10) in /var/www/html/main.html on
line 11
Warning : Cannot send session cache limiter - headers already sent
(output (- etc etc like the one earlier))
(These are the lines containing session_start(); and
session_register("login"); in the main.html file)
In my phpinfo(), I find that
session.auto_start=ON
session.cookie_limiter i=nocache
session.cache_expire=180
session.save_path=/tmp
session.serialize_handler=php
Where could I be wrong ?

[PHP-DB] Session variables
I'm experimenting with sessions and note that you seem to able pass a query
result id via an include but not via an . Is this correct or
have I got it wrong? Do I need to do something to $session[result] before
passing it via ? Example scripts:
session.phtml:
$connection = mysql_connect($DBHost,$DBUser,$DBPass);
mysql_select_db("$DB");
session_start();
session_register("session");
$session["result"]=mysql_query("select * from $TA");
$rows = mysql_num_rows($session[result]);
echo "Rows in session = $rows";
echo "Pass";
echo "Send";
include ("sessionresult.phtml");
sessionrows.phtml:
echo " Rows in sessionrows = $rows";
sessionresultid.phtml:
$rows = mysql_num_rows($resultid);
echo " Rows in sessionresultid = $rows";
sessionresult.phtml:
$rows = mysql_num_rows($session[result]);
echo "Rows in sessionresult = $rows";
Output from session.phtml reads:
Rows in session = 7
Pass
Send
Rows in sessionresult = 7
Clicking on Pass outputs "Rows in sessionrows = 7" as expected. But Clicking
on Send outputs the "Warning: Supplied argument is not a valid MySQL result
resource ..." error. I also get this when I click Back from either
sessionrows.phtml or sessionresultid.phtml. Again not sure why?
Any help gratefully received.
