RE: [PHP] $HTTP_SESSION_VARS still holds original values even after unset?
Something else in your code is messing you up if you cannot change the value after setting it in the first place. This happens all the time in my code as my client makes decisions along the way. Try a small test creating a session variable, displaying it, changing it, and redisplaying it. If it does not show the change, post the test code so we might be able to tell why it fails. Provided you can change the variable, you should be able to create a loop that sets all the variables to or some base values etc. Larry -Original Message- From: Andy B [mailto:[EMAIL PROTECTED] Sent: Sunday, April 04, 2004 6:03 PM To: [EMAIL PROTECTED] Subject: [PHP] $HTTP_SESSION_VARS still holds original values even after unset? how would you empty all the contents of $HTTP_SESSION_VARS when you dont need them anymore but still keep the current session running? the problem seems to be that when i try to fill them with something else (dont need the original values anymore) but need new ones without destroying the session itself they wont fill with new things. unset($HTTP_SESSION_VARS); does nothing to help at all because they still have the same values that they were originally filled with (and not to mention they are still in the session)... anybody have any ideas how to delete or empty out the array but keep the session active ?? -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

Rasmus
OK, I think I understand the principle now, yet, when I implement id, my
app still fails.
I have register_golbals = on, BUT, I want to find a way to code that I
know will always work, regardless of register_globals or cookies, so
that I am only dependant on the trans-sid ( but If I could rule that out
too, it would be even better)
How do you write your apps so you know that they will work on most
configurations? I have a bunch of older apps that will definately break
if I upgrade the server and turn register_globals off, and I want to
prevent it from happening with new apps I write now.
With what you said below, can I assume that:
1) If I know all the variables that I will need to be session variables,
I can session_register() them all on the first page, and then simply
give them values during the normal flow of the app?
I have tried to implement what you said below in my app as follow,
basically the route is:
Login form -- action page:
action page links to another form page
form page -- action page
All these pages are supposed to be part of the session, but between the
last two pages, the session disappears, and the form doesn't pass
variables...
I'm so utterly fed-up with myself for not being able to get this right.
Can you see ANYTHING that might cause this?
index.php
?php
session_start();
?
form name=form1 method=post action=admin_select.php
table border=0 cellspacing=0 cellpadding=0
tr bgcolor=#CFCFCF

from the drop_down, or you can add a new project, It is with the
second route that I pick up further problems:

This example assumes the machine is running PHP = 4.1.0 allowing use of
$_SESSION rather than $HTTP_SESSION_VARS. Adjust as needed.
session_start();
if ( !isset($SessionID) ) {
# This likely means that register globals is off.
# So, loop through the session vars and create regular vars.

Re: [PHP] $HTTP_SESSION_VARS vs $_SESSION - cont.
No real reason to start the session in index.php. You are not registering
any session vars, nor are you accessing any.
index.php
?php
session_start();
?
form name=form1 method=post action=admin_select.php
table border=0 cellspacing=0 cellpadding=0
tr bgcolor=#CFCFCF
td colspan=2Admin Login
/td
/tr
tr

tdPassword:
/td
tdinput type=text name=pass_word
/td
/tr
tr
td
input type=submit name=Submit4 value=Submit
/td
/tr
/table
/form
Ok, now that we are in admin_select.php you can start the session, which
you do.
Then:
admin_select.php
?php
session_start();
if ((!$HTTP_SESSION_VARS[username])
(!$HTTP_SESSION_VARS[password])) {
session_register(username,password);
}
if (($HTTP_POST_VARS[user_name]) ($HTTP_POST_VARS[pass_word])) {
$username = $HTTP_POST_VARS[user_name];
$password = $HTTP_POST_VARS[pass_word];
}
Looks ok so far. Although I am not sure session_register() was able to
take multiple args in 4.0.3. But you don't need the check. Nothing bad
happens if you session_register() the same var twice.
$link = mysql_connect(localhost,$username,$password) or die

mysql_select_db(mafisa,$link);

Again, you don't register nor do you use any session vars in
admin_add_project.php so there is no need to start the session.
Now, on this last page that is supposed to insert the form data into the
db, there is simply no form data, or session variables!
admin_add_project_do.php
?php
session_start();
$date = date('Y-m-d');

or die ('Could not connect!');
mysql_select_db('mafisa',$link);
$project_name_db =
addslashes($HTTP_POST_VARS[project_name_add]);
$project_description_db =
addslashes($HTTP_POST_VARS[project_description_add]);
$sql = insert into project_table
(project_name,project_description,date) values
('$project_name_db','$project_description_db','$date');
$result = mysql_query($sql);
echo 'Thank you, new project ::
bi'.$project_name_db.'/i/b was added to the system. br
a href=admin_select.phpBack/abr';
?
Looks ok. Is it only on 4.0.3 that this isn't working?
Why don't you do this instead at the top of each page where you want to
use the session vars:
if(!ini_get('register_globals')) {
extract($HTTP_SESSION_VARS);
}
Then just use plain $username and $password. See if that makes a
difference. But you really should get your provider to upgrade to
something a lot more recent than 4.0.3. Do you realize that 4.0.3 is
almost 2 years old now? That's an eternity on the Web.

Re: [PHP] $HTTP_SESSION_VARS vs $_SESSION
You lost me there...
Are you saying I don't need to access those variable in that way?
Can I simply use $variable in successive pages then?
Surely I MUST use that notation to assign values then right?, specially
to the session vars, right?
But, just out of curiosity, why does it work fine on my newer system?

Re: [PHP] $HTTP_SESSION_VARS vs $_SESSION
Oh, almost forgot,
I *think* the reason why I'm still worrying about the $HTTP_* arrays are
because I *think* that it is the correct way to work with the vars once
register_globals is turned off ( which is where things are moving to
right?), and I don't want to re-code my scripts...
Am I making sense?

Re: [PHP] $HTTP_SESSION_VARS vs $_SESSION
No, you don't need to use HTTP_SESSION_VARS for anything if
register_globals is on. Sessions are very simple. You start a session,
and you register variables to be part of that session. Like this:
session_start();
session_register('a');
session_register('b');
If you have that at the top of the first page, then whatever values $a and
$b have by the time the script finishes is what will be written to the
session backend.
So, on a subsequent page you just do:
session_start();
This will see the session ID that the browser passed to it either via a
cookie or in the URL and it will go and restore the variables from the
session backend. That means that at this point you can just do:
echo $a;
echo $b;
At no point is there any need for $HTTP_SESSION_VARS nor $_SESSION if you
are sure that register_globals will always be on.
Now, if you want it to work with register_globals off, you still don't
need to use $HTTP_SESSION_VARS when setting the variables, you only need
to use it when retrieving them. So, instead of echo $a and echo $b you
would have:
echo $HTTP_SESSION_VARS['a'];
echo $HTTP_SESSION_VARS['b'];
Or, of course in newer PHP's you can use $_SESSION['a'].
Your stuff probably didn't work because you were setting the session vars
via the $HTTP_SESSION_VARS array. That works now, but it probably didn't

Are you saying I don't need to access those variable in that way?
Can I simply use $variable in successive pages then?
Surely I MUST use that notation to assign values then right?, specially
to the session vars, right?
But, just out of curiosity, why does it work fine on my newer system?
Thanks

Hi
Me again
Still having problems with forms not sending variables, and session
variables dissapearing.
I have 2 systems, one older 4.0.3 PHP which is my main webserver, so all
scripts must comply with it...
And the other my development server with the latest 4.1.2
So, I'm trying to write scripts that will happily work on both, and I
understand that I must use HTTP_POST_VARS and HTTP_SESSION_VARS in order
to comply with 4.0.3.
register_globals and track_vars as well as trans_sid are enabled on
both.
Now, take a look at the example below:
index.php
form action=page2.php method=POST
input type=text name=testinput type=submit name=submit
/form
page2.php
?php
session_start();
echo ' HTTP_POST_VARS :'.$HTTP_POST_VARS[test].'br';
echo ' POST_VARS: '.$_POST[test].'br';
echo ' normal test :'.$test.'br';
echo 'Session Value (only for
re-entry):'.$HTTP_SESSION_VARS[testing].'br';
if ($HTTP_POST_VARS[test]) {
$HTTP_SESSION_VARS[testing] = $HTTP_POST_VARS[test];
}
echo 'a href=page3.phpClick/a';
?
page3.php
?php
session_start();
echo 'Session Variable:'.$HTTP_SESSION_VARS[testing].'br';
echo 'a href=page4.phpForward to test sess var further/abr';
echo 'a href=page2.phpBack to test sess var/abr';
?
page4.php
?php
session_start();
echo 'Session Variable:'.$HTTP_SESSION_VARS[testing].'br';
echo 'a href=page3.phpBack to page 3 to test sess var
further/abr';
echo 'a href=page2.phpBack to page 2 to test sess var/abr';
?
This small test works 100% on my newer system, and I was under the
impression that I coded it to be backwards compatible with my older
system, BUT,
look here: http://www.linuxhelp.co.za/session_test to see what it does
on my working server. The scripts are identical.
Please can you point out my mistakes in reasoning?
Also, I want these scripts to work regardless of cookies, so if you see
something that might cause problems when ppl disable cookies, plz
advise.

Re: [PHP] $HTTP_SESSION_VARS ? Have I got it wrong
Define the value of $count before registering it, and it should work fine :o)

The answer is probably yes.
I do a
session_start() followed by a $HTTP_SESSION_VARS['count']=2 on one page.
Then I go to another page and do a session_start() again; unfortunately
the $HTTP_SESSION_VARS['count'] is empty!!!
I tried doing a session_register('count2'); $count2=123; in the first page
followed by another page where I display $count2 and that works fine.
Why?

Re: [PHP] $HTTP_SESSION_VARS ? Have I got it wrong
If you're going to use $HTTP_SESSION_VARS, then you have to use
session_register().
?
session_start();
session_register('count');
?
Next page:
?
session_start();
echo $HTTP_SESSION_VARS['count'];
?
That should work. If you use $_SESSION, instead, then you don't have to use
session_register.
That's how I understand it...

Re: [PHP] $HTTP_SESSION_VARS with unset()
I must ask first, why don't you just use the session_destroy() function? it will kill all related sessions variables and reset the PHPSESSID (if that's you have it named) Jim Lucas www.bend.com - Original Message - From: SpamSucks86 [EMAIL PROTECTED] To: [EMAIL PROTECTED] Sent: Thursday, March 14, 2002 4:54 PM Subject: [PHP] $HTTP_SESSION_VARS with unset() when someone logs in, it sets $HTTP_SESSION_VARS with the appropriate information. to log them out, I tried just using unset($HTTP_SESSION_VARS['valid_user']) but it doesn't actually remove it from the session. it will only work if valid_user was set on the same script call (for example, if it logs me in and then immediately logs me out without making another call to the script). How come $HTTP_SESSION_VARS won't destroy session variables unless they're created during the same script call? Or maybe it just has to do with if $HTTP_SESSION_VARS creates any variable before it deletes any.

The best bet, IMHO, is to upgrade to 4.x, tho.

Make session capital!
$HTTP_SESSION_VARS instead of $HTTP_session_VARS
Might also use:
foreach ( $HTTP_SESSION_VARS as $k = $v )

Change HTTP_session_VARS to HTTP_SESSION_VARS, since variable names are
case-sensitive.

Re: [PHP] HTTP_SESSION_VARS
if there aren't any session vars, $HTTP_SESSION_VARS won't be an array.
i use something like
if(isset($HTTP_SESSION_VARS)) {
reset($HTTP_SESSION_VARS);
while(list($k, $v) = each($HTTP_SESSION_VARS)) {
do_something($k,$v);
}

In that case, $HTTP_SESSION_VARS is not an array because you have no session
variables yet...
session_start();
session_register('foo');
$foo = 42;
while (list($k, $v) = each($HTTP_SESSION_VARS)){
echo $k ==gt; $vBR\n;
