[PHP] Control over your Session
Got a problem thats baffling me.
I have a form that includes a file that starts a session.
Creating sessions are no problem, but deleting the session variable is
not working as its supposed to.
Sudo code -
?php
include('some_file.php'); // This file starts the session via
session_start();
switch( $bar )
{
case 'post':
// do logic and insert into db
unset($_SESSION['foo']); // we are finished with session variable,
so delete it
break;
case 'preview':
// preview form contents and set session to persist
$_SESSION['foo'] = 'some data';
break;
default:
if (isset($_SESSION['foo']))
{
unset($_SESSION['foo']);
}
// display form here
break;
}
?
For some reason thats beyond me, using unset() to kill the session
variable isn't working.
Does anyone know what could be causing this type of behaviour??
Any help would be appreciated.
Thanks

Re: [PHP] Control over your Session
If you have register_globals on, you'll need to session_unregister it.

Re: [PHP] Control over your Session
Thanks for saving my sanity. The best answer is the simplest one.
Im testing my code on a domain where register_globals were on. Never
would have thought of checking that.
Thanks once again, now I can go to sleep...

[PHP] Problem with apache php and SSL
Hi, I'm a newbie with php and I have a big problem with the use of PHP 4.1.1 with apache/1.3.26, mod_ssl/2.8.10 and OpenSSL/0.9.6d. (Tested on Windows and Linux) For a demonstration I have to get the user certificate of an SSL connection to identify the user. I try to get information's about the client with the following script: ?php echo Info: \; echo getenv(REMOTE_USER) . \br; echo \ . getenv(SSL_USER) .\br; echo \ . getenv(LOCAL_USER) .\br; echo pSSL Version used: .getenv(SSL_VERSION_LIBRARY); echo pYour Name: .getenv(SSL_CLIENT_S_DN_CN); echo pYour Certificate are signed by: . getenv(SSL_CLIENT_I_DN_CN); echo CLIENT br; echo Issuer: . $_SERVER['SSL_CLIENT_I_DN'] . br; echo Subject: . $_SERVER['SSL_CLIENT_S_DN'] . br; echo Validity Start: . $_SERVER['SSL_CLIENT_V_START'] . br; echo Validity End: . $_SERVER['SSL_CLIENT_V_END']; ? The SSL connection work properly (I debug the client info from apache in a file) but none of the parameters I used above are set to anything. Are there special settings in a configuration file or have I compile one package with special parameters to get an access to the SSL client certificate information's? Thaks a lot for every answert!

Re: [PHP] dynamic/multidimensional arrays in classes

You are using a variable defined within the class - since it is a class variable you can reference it as you would anything else within the class, using '$this-'

I've also tried using count() to find out how many items are in $arr, but it
keeps saying that $r == 0... i.e.
function add_something( $value )

$r = count($arr);

$r = 0;

//print( $r );
$this-$arr[$r] = $value;

I've tried this both with without the commented section still $r = 0
even if you use '$class-add_something(my value);' 50 times. I'm guessing
once this problem is solved it will work for multidimensional arrays as
well?

Re: [PHP] sessions
Nothing is safe unless it goes over SSL, and even then, NOTHING is 100% secure :) The point is that you shouldn't have the plain text password as a session var... Your login form (and the script that varifies the login) should be secure (see note), and should establish a session var like logged_in NOT session vars like password. This way, IF the session is hijacked, the hijacker can only hijack that session NOT find out what the user's password is. Note: The real issue you have is that the password can be seen in plain text when the login form is submitted... therefor, you need to be concerned about running the login process under SSL.

Re: [PHP] Forcing page refresh with http headers?
a trick i use is with the time() function
e.g.

then
header('location: .page.php?var=' .$var);
This forces the browser to retrive the page again from the server.
might be of some use.

I've used the HTTP Location, Expire, and Refresh headers to no effect.
What's the magic order to
1) Refer a browser to a new location
2) Ensure that the location is refreshed?
I want to avoid using meta http-equiv tags, as this complicates things

[PHP] Calling Multi-Row Result PHP Variable in Flash
Hi,
I used a script to generate some result from a
database, which i want to display in flash.
In Flash, i created the Dynamic Text and declared
newsbits as Vars, and set it to Multiline.
I also loaded the PHP variables with the following
command in the ActionScript of the Frame :
loadVariablesNum (newsbits.php, 0);
The problem is.. my PHP Script generates a multiline
result.. that is, 4 rows are returned.. however, in my
Flash file, only the Last Row is displayed.. the first
3 are not.. how do i do this?
In my PHP file (newsbits.php), i'm running the
following code..
?php
$db = mysql_connect(localhost,user,pass);
mysql_select_db(myDB,$db);
$result = mysql_query(SELECT substring_index(title,'
', 6) FROM news ORDER BY ID desc limit 4,$db);
if (!mysql_num_rows($result)) {
print 'no results';
} else {
while (list($title) = mysql_fetch_row($result)) {
print newsbits=$title...;
}
}
?
When i run newsbits.php on my server, i get perfect
result.. 4 rows are returned, but in my Flash only the
last record is appearing.. What do i have to do so
that all 4 rows appear?
I tried the following in my php : print
newsbits=$title...br;
which obviously will seem silly to those who know
something about this.. but hey, 'm desperate. :0)not
to mention it didnt work!!

You'll need to have PEAR::SOAP installed (very easy with php-4.3).
Get SOAP_Google.php from http://www.sebastian-bergmann.de/?page=google
You'll need to register with google to get an licenseKey.
Then a simple search:
?php
require_once 'SOAP_Google.php';
$google = new SOAP_Google('your license key');
$result = $google-search(

On my system, my probability is set to 1, meaning there is a 1% chance of the garbage process starting when I call a new session, and my garbage define time is 1440, meaning if the data is older than that amount of seconds, then it is to be considered garbage by the next garbage process, and hence, destroyed...

[PHP] html mail
Hi, I am quite new to php and I am trying to find a way of sending details of a web form over e-mail in both text and html format. There are numerous sites on the web that try and explain how to do this but they are worded very complicated and to be honest I haven't found one that is particularly good. I want to send an e-mail that contains html code, with the option of attatching images and other files as well as a text version of the email so that the viewer can read the same e-mail whether or not he can view html email or not. Any ideas? Ian Gray. = - Ian A.

Any text field will do, just make sure it's large enough for your data.

RE: [PHP] MySQL and PHP arrays
Serializing it would be the best way: seralize($myArray)
then you can get the array back using unseralize($serializedarray)

Possibly using array_keys()?
$keys = array_keys($doo);
echo First key is \{$keys[0]}\;
array_keys() comes in handy if you want to have random access to an
associtive array without knowing the keys.

[PHP] standard html, hidden table's row and controls
good day to all readers. It's specifically a javascript question. I've a form containing a hidden table, and inside of this last, controls that contain useful information invisible to the user, for example, hidden select tags that contains set of items, only subsets of it are visible to the user. form name=form_HiddenSets table tr style=display:none td select name=R_InstitutionsSet_Institutions ... option tags /select /td /tr /table /form if the row is invisible I receive this message frm.R_InstitutionsSet_Institutions has no properties. changing tr style=display:none to tr the program works correctly. Any suggestion? ?why this error, when no matter if the row is visible or not, the object R_InstitutionsSet_Institutions should be part of the form? I use only the most standard html specifications, using NetScape navigator to test my program; over IE, this solution works perfectly.

Using that number, you should be able to indent the code properly. I need to count how often the important tags (table, tr, td) have been opened, but that's only a part of the solution. It doesn't make sense to count every and because most of the tags don't play a role (in the script I should write). Let us know what you've got so far. I solved the problem by first getting all position of the table, tr and td-tags. After that I go serially from the first to the last occurence of a tag and keep track how often it was opened and closed. Additionally I have a variable which counts the numbers of bytes I added to the text. After that I reduce the linelength to less than $maxlength chars.

[PHP] HTTP_REFERER security implications?
I am working on a simple authentication script, where the user submits a login and password, the credentials are checked and the user is redirected to another script. The new script checks the HTTP_REFERER and if its the original script it continues, otherwise it stops with a message about being unauthorized. What kind of security implications may I be backing myself into? I want to try and stay away from cookies, and as small as this is I think Session management is a little overkill. The average user isn't going to spend much more than 1 or 2 minutes on the site (not much for them to see or do).

Re: [PHP] quick question
You should look at E-xact (http://www.e-xact.com). They have a solution they call tagged transactions that actually replaces the credit card numbers with tags that are only meaningful in the context of your merchant account. That way, you can let your customers make repeat purchases without actually having to store CC numbers on your site.

[PHP] Re: standard html, hidden table's row and controls
This is a PHP group please post JS questions to a JS group unless u have PHP code in inside requiring help !!! IE considers it non-active when style.display = 'none' you can not reference it via the 'javascipt' controls. it must be made visible to work in IE... i think u should look at another solution. perhaps an array of the items stored in javascript with a simple input type=hidden to store the active one. i have ALOT of experience with the div style hidden areas. Joel Enediel [EMAIL PROTECTED] wrote in message news:[EMAIL PROTECTED] good day to all readers. It's specifically a javascript question. I've a form containing a hidden table, and inside of this last, controls that contain useful information invisible to the user, for example, hidden select tags that contains set of items, only subsets of it are visible to the user. form name=form_HiddenSets table tr style=display:none td select name=R_InstitutionsSet_Institutions ... option tags /select /td /tr /table /form if the row is invisible I receive this message frm.R_InstitutionsSet_Institutions has no properties. changing tr style=display:none to tr the program works correctly. Any suggestion? ?why this error, when no matter if the row is visible or not, the object R_InstitutionsSet_Institutions should be part of the form?

Hello,
Am I correct in my understanding that for a multi-select input, PHP
requires
that the name attribute end with square brackets (i.e. select
name=my_select[] multiple) in order for the submission be handled
properly?
I know this is somewhat nit-picky, but this seems to unnecessarily expose
the underlying technology such that scanning the HTML source reveals that
a
PHP script will ultimately parse the submission.
I'm hoping there's some alternative technique I've missed...
-Dan
Yes. The values must be passed as an array. In order to do that the select
tag requires the [] braces. The proper syntax is:
select name=my_select[] multiple
optionOne/option
optionTwo/option
optionThree/option
/select
?
// To read the selected items...
for($i=0; $icount($_POST['my_select']); $i++)
{
echo $_POST['my_select'][$i].br;
}
?
Hope that helps.

[PHP] PHP static module on Apache 2.0 HPUX 11
Folks, I am trying to build Apache 2.0 /PHP (latest) on an HPUX 11. I configured both of them to handle DSO. PHP generates the .so, which later I rename to .sl and move to the modules directory and run make install successfully. After adding the LoadModule and the Addtype directive, apache gives an error saying the it cannot find the libphp4.sl file. On the error message, it outputs the path - ( When I copy and past the path on a ls command, I can see that the file exists, and the permissions are set correctly) When I manually run apxs on the file, ( apxs -i libphp4.sl ) it tells me that the file is not a DSO. If I run the 'file' command on it, it tells me that it is indeed a DSO. -- So, I gave up on the DSO route and switched to STATIC. 1) PHP build does build the static lib libphp4.a; however, make install DOES NOT copy it to the apache source directory (as described on the docs) -- Fine, I copied it manually. 2) As described on the INSTALL file, I pass the --activate-module for apache. However, Apache2.0 does not take the --activate-module=modules/libphp.a; it says that activate-module is an invalid flag. I ran ./configure --help and there was nothing similar to this falg. Any help would be very apreciated. (All the help on php.net about HP has does not address this issue. Also, there is not docs on how to install PHP/APACHE2.0 as static.) Thanks for the help.

[PHP] A question of time...
Hi all, I recently had a freelancing experience that has left me somewhat sour and questioning myself. Unfortunately I don't feel I can fairly evaluate myself and so I owuld like to put the question to my peers who populate the PHP forum as to whether I have performed competently. Last week I took upon myself the task of fixing a clients shopping cart system by way of adding session support and proper user registration validation. To give you some idea of the parameters of the job... - VNC development connection - live server with no error output - no session support whatsoever - cart had no input validation, except basic javascript - user registration permitted clobbering of other users and had no validation either - PHP code was ad-hoc sprinkled through the pages - comments were almost non-existent The first day I decided it would be best to mirror the server so that development time would be minimized (VNC is terrible for devlopment). This was done without charge to the client despite it's time saving effect. The second day I spent 13 hours familiarizing myself with their code and pages, and on this day I also implemented a session management library for easily accessing and setting session data (this included hooks for permanent cookie data storage). I also fixed the user registration process and add security validation to ensure user information could not accidentally (or deliberately via form hacking) be accessed by someone other than the registrant. Previously re-registration of an existing email address regardless of password would clobber existing customer. At this time I also fixed the cart and ensured prepopulation of forms for updating registration information. The third day I first wasted an hour making my changes work on their server because they decided to rename all the files I had changed thus breaking all of the include() paths. After that I spent another 3 hours adding support for returning to previous page before entering any of the cart checkout or customer registration pages. At this time a response page was also added to thank the customer for their purchase. Of course all of this was tested to be functional and where necessary broken pre-existing code was replaced or fixed to provide the correct functionality. On the fourth day I spent 3 hours adding support for input validation feedback to the registration validation so that customer's would know exactly why they could not continue. I also added support for a password reminder to inform the user of their password when forgotten. This included adding the page, adding the form, validating that the user id existed and outputting appropriate feedback if the user did not exist - and of course testing. All in all I spent 20 hours total for the client at a rate of $40 USD/hr which I believe is on the low end of freelance. I myself have 3 years experience devloping PHP web applications. So the question I ask is whther this time frame is reasonable, or am I just a slow crappy programmer that is ripping these people off? They seem to think I should have had this done in just a few hours, but my experience thus far indicates to me that they got just service. Additionally it seems before I took the job, they had went through several other PHP developers would said they couldn't do it (and I don't really blame them considering the VNC connection and lack of comments or error feedback). If it turns out that I am incompetent, then I will happily send them a bill for zero hours, otherwise I would like to take comfort that I am not ripping them off.

Re: [PHP] quick question
Right - but the problem is, the form is submitting to another site, so i don't have a way to store the variables. I could put them in session variables, but I would have to create another script and then forward the form submission to the outside side. This isn't working because the outside site requires the variables to be submitted via a form, or POST i guess. I don't even know if I'm going about this the right way - I just need to somehow store variables on my site that are submitted for processing to another site, so that when the user is sent back from that other site, i can put the values in the form fields of a new page. Cpt John W. Holmes wrote: I'm sending credit card info to a 3rd party credit card processing site. I would like to keep the inputted values and, after the approval, have them appear in the value part of the form so that they don't have to re-input the same values they had just put in for the credit card. how can i do this? So put the value in the value attribute of your text box. input type=text name=cc_number value=?=$_POST['cc_number']? substitute $_POST['cc_number'] with whatever you send to the processing site. ---John Holmes... -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

Re: [PHP] Multi-select inputs and naming
Unless you're ashamed to be running php, or don't intend to be spending as much time on security as you should, why would this be an issue? If your app is well-written, the knowledge that it's implemented with php shouldn't benefit a potential attacker. You know what they say about security through obscurity... Hehe, yeah I am being somewhat anal here. I was hoping that with search-friendly URLS (i.e. /issues/2003/mar/ rather than /issues.php?year=2003month=mar), I could have the added security benefit of obscuring the back-end technology. This is more from the theoretical than practical line of thinking, so I'm not too worried. While I agree that if the app is well-written it shouldn't matter, but I figure it couldn't hurt as an added security net. I have another question reguarding the security implications of source readable PHP projects, but I'll save that for another thread. I'm hoping there's some alternative technique I've missed... I guess you could use javascript to create/set individual hidden form fields for the items selected, but if the user has javascript disabled your form ceases to function. I guess this question was coming from a couldn't they have designed in a cleaner way? perspective. Don't get me wrong, I think the way PHP does an outstanding job of handling these particular kinds of form submissions, I just figured there might be an alternative syntax.

[PHP] Sessions problem
Hey all, Some of my users have reported a problem with my site and it's taken a while to debug it, but I think I've finally tracked it down. If they go to the site as: http://www.mysite.org/ Then it works But if they go as: http://mysite.org/ It doesn't. I believe it has to do with my use of session variables. Apparently (I didn't know this, but it's obvious from the debugging) that there are different session ID's and thus different session variables for the two. And the problem is (due to sloppy programming on my part ... sigh ...) that sometimes I set up the links as a href=/page and sometimes I do the explicit a href=http://www.mysite.org/page. So when it goes to the link as www.mysite.org, it registers the variables, but then later when it tries to access and it's just mysite.org, the variables aren't set. Lots of confusion ensues. Is there any way to unify this, or do I have to go through and fix all of the absolute links to be relative?

[PHP] Re: sessions terminating randomly please help
It's possible you're being afflicted with the same problem I am. See
the message just one or two above this about Sessions problem. What I
found in my debugging is that it had to do with how I was
mix-and-matching the way I specified links.
Short version of the problem is that http://mysite.org/ has one session
and http://www.mysite.org/ has another. In my code, I sometimes have
the links as a href=/page and sometimes it's explicit, as a
href=http://www.mysite.org/;. So if a user went to the site as
http://mysite.org - the pages that used the explicit www.mysite.org
would fail.
So if there's anything in your pages/links that may change how the link
is referred, you may be have different sessions occuring.
I would imagine it should be pretty easy for you to debug whether or not
this is the problem. Have each of your pages echo out the current
session id (echo 'session is '.session_id().'br';) and see if it
changes at any point, and especially on the pages that fail.

Make sure that the url is always the same. For example if a user is at a

http://www.mysite.com/phpscript.php (notice the www) the session might not
follow because the url is different.

It's possible you're being afflicted with the same problem I am. See
the message just one or two above this about Sessions problem. What I
found in my debugging is that it had to do with how I was
mix-and-matching the way I specified links.
Short version of the problem is that http://mysite.org/ has one session
and http://www.mysite.org/ has another. In my code, I sometimes have
the links as a href=/page and sometimes it's explicit, as a
href=http://www.mysite.org/;. So if a user went to the site as
http://mysite.org - the pages that used the explicit www.mysite.org
would fail.
So if there's anything in your pages/links that may change how the link
is referred, you may be have different sessions occuring.
I would imagine it should be pretty easy for you to debug whether or not
this is the problem. Have each of your pages echo out the current
session id (echo 'session is '.session_id().'br';) and see if it
changes at any point, and especially on the pages that fail.

hi
i am experiencing a major problem with sessions expiring randomly in some
of my
apps. i will log in and start clicking around and then i will eventually
arrive at a page that tells me that i'm not logged in anymore. this
happens
apparently randomly. i have seen it on ie6, ie for mac, netscape 4.7 for
pc,
and mozilla
the apps are hosted on
freebsd 4.7-release p2
apache 1.3.27
php version 4.2.3
compiled with --enable-trans-sid
i can't go into production if there's the possibility that users will be
randomly logged off. i went through all of my code over the weekend, and i
don't think i can attribute this to a miscoding:
when a user logs in, i create a session with
session_start();
$valid_user=$_POST['username'];
session_register(valid_user);
i have the following code at the top of each page to check to see if the
session
is valid:
session_start();
$valid_user=$_SESSION['valid_user'];
global $valid_user;
if (session_is_registered(valid_user)
{...function to spit out an error message if the session is not valid...;}
i have a logout page that destroys the session
session_start();
session_destroy();
i also have a javascript timer in the header of every page that redirects
to the
logout page if the user has been inactive for 20 minutes.
i have played around with session.gc_probability, setting it to 100, but
that
doesn't seem to have fixed the problem.
this is a huge problem.
if anyone can give some advice, i'd really appreciate it.
thanks
