PHP :: Get User Information

Tracking User Information
I'm having some trouble with tracking user information. I'm currently stuck with the forums on my gaming website, i need to track what topics have been read by the user and wich topics are yet to be read. (e.g. newly created topics appear as "not read yet" to whoever hasn't read the topics).

I've tried numerous way's to do this with sessions but it didnt turn out very well. I see boards everywhere displaying correctly wich topics i haven't read yet and wich i have read already. Any idea's on how to do this?

Maintaining User Information Throughout Session
Ok guys, you have been so helpful in the past. Here's another one for you..

I am developing a protected section of my companies website where customers can register and obtain access to forums, whitepapers, etc.

I have developed the login page, profile pages, etc, but one thing I dont know how to do it make sure that as long as my user is logged in, if they click on the "Profile" link, they will see their, and ONLY their user profile info.

I am investigating global and/or session variables to keep the 'userid' field in memory throughout the session and provide me with a way of always identifying the user.

Am I going down the right path? Any suggestions on where to look, ie - tutorials or something?

Advice About Fetching User Information
I have this content management system I've developed myself. The
system has a solid community part where members can register and then
participate in forums, write weblogs and a ton of other things.

So, in instances where I list, for example, the latest weblogs. I list
the headline of the weblog, the date and the name of the member who
wrote it.

Now, the name isn't just "Smith", but rather Smith's online status,
his nick and his "label", and can look like this:

<imageSmith M:34

The image is either a green or red dot depicting his online status.
When I want to display this, I use this function:

print member_name(12);

With 12 being the id number of Smith, and the only information about
the writer of the weblog (i.e. I don't save his nick or label in the
weblog post, and certainly not his online status).

So, when using member_name() I look up the id 12 in a prefetched array
of members, displaying the correct information. In a compact format:

## index.php
require_once("member.php");
print member_name(12);

## member.php
$q=mysql_query("select id, name, label from members");
while ($r=mysql_fetch_assoc($q)){
$GLOBALS["members"][$r["id"]] = $r;
}

function member_name($id){
$m = $GLOBALS["members"][$id];
$online = in_array($id, $GLOBALS["surfers"]) ? "on" : "off";
return icon("online/$online") . " $m[name] $m[label]";
}

##

So, whenever requiring member.php, all members are prefetched and put
into $GLOBALS["members"], which has worked just fine. Then I have
infromation about any given member at my fingertips.

But now I have some sites which are beginning to get a pretty large
number of members, so prefetching them all becomes timeconsuming
(sometimes up to one second, which is unacceptably slow).

I can't fetch information about each single individual at the point of
showin his or hers information since there can be long lists of for
example weblogs and there might be 40-50 member names to be shown,
which would result in 40-50 seperate mysql requests, which would flood
the MySSQL server, I'm afraid.

So, my question is this; what other way can I do this in? Is there a
faster way to read thousands or even tens of thousands of information
points and put them in an array quickly?

Or is there a better way to read information about single members at
runtime?

Aggregation is most certainly an option. Can I write a tab separated
text file and read that one in member.txt - would it be faster? Should
I write one text file per user and read that file when needed?

Anyone got any experience in doing this? How did you solve it?

Adding User Information To A Form
I need to be able to take some user details on one page and then be able to put the information gathered onto another page that already contains another form that has been created by a javascript cookie program.

Thing is i need the initial user information captured to be 'pasted' in to the final ordering page and to remain there (so that more products can be added) without the user having to re input their details again.

I have just started with PHP and know that i can set up a form and that PHP can print the variables from the form , but how do i get those variables to remain fixed in the next form and be able to let users go to other pages within the site without losing the data?

Updating User Information Php/mySQL
im fairly new to the incorporation of php and mySQL and i am looking to start off by making a user info database that will hold contact information as well as a username and password field. below is the code for the site i want to use to allow the user to "update" their info. My problem is when i click the link to "edit" info after the user has logged in, the page displays blank. Code:

Capturing User Login Information Of Windows
I want develop the intranet site with seamless authentication. Is there
any way to capture only the user name who has logged in the windows
machine.

Iam using PHP 5.0 MySQL and IIS Server.
I have tried with $_SERVER['LOGON_USER'] but its returning nothing.

PHPmyadmin Access Denied For User 'user'@'localhost'
WinMe machine as server, with Apache 2 installed and working PHP4 installed and working ( had PHP 5.05 installed and working, but i couldnt get the mysql extensions to load - phpinfo() didnt list mysql :(, so i installed PHP4, which now lists mysql when i run phpinfo). MYSQL 4.1 installed and working. I dont know the console commands too well, but i know its working ok, cos I have used a few simple DOS prompt commands to check its alive and I can connect to the database using MyODBC frontend/driver 3.51 and also using Navicat 2004.

When i try to connect to the database via PHPmyadmin from another network PC I have an error:

#1045 - Access denied for user 'user'@'localhost' (using password: YES)

I have played around alot with different settings in the config.inc.php file.... nothing seems to work.

This almost appears to be a simple login problem ( probably is too), but I can access the database locally from the Winme machine with the username and password that wont work over the network!

I have tried not using 'localhost' as the host name but the IP address of the Winme PC but I get this error:

#1130 - Host 'MYSERVERNAME' is not allowed to connect to this MySQL server

Notice: Use Of Undefined Constant User - Assumed 'user'
I have a script for a shopsystem on a Linux. There it works fine.
But when I try to run it on my Windows machine, PHP says things like

Notice: Use of undefined constant dbname - assumed 'dbname' in
c:apachehtdocsaposhop estshopclassesxxx.clas s.php on line 77

On Windows I run PHP 4.3.2
On Linux runs PHP 4.3.1

Authenticating User Common User Names
I want to create a password protected page with PHP and Mysql. I have 2 groups User and Admin. The respective groups have a common user/password. The user/password are stored in a database. I want to authenticate the user through a login form and not through a pop-up ($PHP_AUTH_USER) way.

What I want is, if a user logs in and he moves from one page to another, he should not be asked for validity again. Is this possible only with scripting (without session and $PHP_AUTH...). If yes - how do I keep track of an authorised user and unauthorised user, so that he should not be validated again. Does setting the user variable to global in all the pages do the trick.?

User Authentication And PHP Saving As Specific User.
the users of my server had to upload their pages by sftp and only the user who uploaded a page was able to edit itafterwards.

I've been asked to make a secure way for users to log on through the web and edit their pages online. However, although using .htaccess to authenticate users, the script saves as user 'nobody' and is not able to edit pages previously uploaded (and saved as user 'john_doe'). What I am trying to do is make the script save using the same username as the user used to log on.

Fill Fields When User Selects User From DB
I have a field with a selectbox which contains a list of client names and several other fields which display information from the DB.

I need to be able to make the fields change to the appropriate information when a user is selected from the select box. Can anybody please give me an example of a bit of code that will do this?

The problem is that I do not know how to incorporate this in the script.

How To Get Client's Information?

PHP Cookie Information
How do I read the expiration time for a cookie? I understand that reading the value of a cookie is just $HTTP_COOKIE_VARS["CookieName"] but is there a way to read when it expires?

What I'm trying to do is make a login with a "remember me" option. So if you choose "remember me" the cookie is permanent, but if not it expires an hour after you are done with the admin section of the site.

So I need to keep updating the cookie to expire after an hour, but only if it is set to expire less than an hour from "now".

Retrieving Information From URL
I want to make it easier for a user to get to a comment on my page and to be able to go directly to that comment when it is typed into the URL.

For example, instead of this: http://www.mysite.com/comments.php?id=1

Cannot Add Header Information - Headers Already Sent
I've got this annoying error:

Warning: }Cannot add header information - headers already sent by (output started at c:program filesapache groupapachehtdocsdevadminauth_user.php:2) in c:program filesapache groupapachehtdocsdevadminauth_user.php on line 16

Trying to get my head round this one, but to no avail.

Basically I've got this login script, its a HTML file, and when you login in, and you've not entered anything I've used the header function to re-direct the user back to login section, and if the user if sucessful, I would like them to go to the next section, again using the header function.

Can someone point me in the right direction,

if ((!$username) || (!$pass))
{
echo "Username and Password must be entered";
header("location: http://localhost/dev/admin/login1.html");
exit;
}
$result=mysql_query("SELECT * from user_addition where username = '$username' AND password = password('$pass')");

// check for any results from the query by counting number of rows returned in the result set
$num = mysql_num_rows($result);

// if number of returned rows is more than 1, a match was found
if ($num != 0)
{
echo "1";
header("Location: nextsection.html");
exit;

} else {

echo "INCORRECT";
#header("location: http://localhost/dev/admin/login1.html");
exit;

Website And Tracking Information
i need some information on how you guys would go about making a website that could give you information based on a number you put it. This information will be tracking information on a particular package. The number will be a given number that corresponds with that package. Basically, all the files are dbase files that need to be converted into something readable. I then need to be able to use php or something to search through the readable information from the dbase file and then put it on the screen for the user looking for the tracking information. How would you go about this.

Warning: Cannot Add Header Information -
Everytime i try to use headers on win2k/apache/php4 i keep getting errors. I dont have a clue why i get them.. but anyway, i use this code(from webmonkey):

<?php

// File Name: auth02.php

// Check to see if $PHP_AUTH_USER already contains info

if (!isset($PHP_AUTH_USER)) {

// If empty, send header causing dialog box to appear

header('WWW-Authenticate: Basic realm="My Private Stuff"');
header('HTTP/1.0 401 Unauthorized');
echo 'Authorization Required.'
exit;

} else if (isset($PHP_AUTH_USER)) {

if (($PHP_AUTH_USER != "admin") | | ($PHP_AUTH_PW != "abc123")) {

header('WWW-Authenticate: Basic realm="My Private Stuff"');
header('HTTP/1.0 401 Unauthorized');
echo 'Authorization Required.'
exit;

} else {
echo "
<P>You're authorized!</p>
";
}
}

?>

and when the output i get in my browser is:

Warning: Cannot Add Header Information
Warning: Cannot add header information - headers already sent by (output started at functions.php:1) in /home/victor/www/cart_action.php on line 89

cart_action.php is a php file without interface but just doing re-direction using Header(). functions.php is a file contain inside cart_action.php which do not have any interface but contain several functions written by me.

This happen suddenly, and I am very sure that I didn't output or echo anything before the header(), what is the possible problem like?

Cannot Add Header Information - Headers Already Sent ...
Hello all,

I'm very new to PHP, and have been desperately trying to make the submit button on my form redirect to a confirmation page. But the header() function keeps giving this kind of error message:

----------------
Warning: Cannot add header information - headers already sent by (output started at /customers/mydomain/mydomain/httpd.www/mysubdomain/header.php:1) in /customers/mydomain/mydomain/httpd.www/mysubdomain/mail2.php on line 5
---------------

My code looks like this in the header of mail2.php:

-----------
<?php
if ($_REQUEST["Submit"]) {
header("Location:confirmation.php");
$Email = $_REQUEST['Email'] ;
mail("me@me.com", "Newsletter", "From:$Email");
}
else {
}
?>

Php 5 Information, Tutorial, Book, Etc
I have worked on php for the past 6 years off-and-on and I was planning on making the conversion over to 5.x and I understand there has been a lot of changes from 4.x. Based on this, I was wonder if you could suggest a book that highlights the changes with examples as well as a site or two that would help with this.

On another note, I would like to know how you guys seperate and tier your applications in php (I have been working with .NET in which we used a 3-tier). Do you try and use 3-tier, 2? How do you pass around the connection in php when you seperate the code (use some type of global or always pass the connection)? Etc?

Where To Find Pipe Information?
On a Linux platform, I have the need to call a compiled 'C' program from a
PHP script (to do some special authentication), and to keep the information
passed from the PHP script to the compiled 'C' program secret, i.e. the
information should not be passed on the command-line.

The PHP pipe manipulation functions (such as popen) were suggested to me.

Where can I find out more about pipes, specifically:

a)How to use the C library calls to manipulate pipes?

b)The Linux API (below the C library)?

I need enough information to write the compiled 'C' program, to exchange
information with the PHP scripts via pipes, and to handle exception
conditions.

I'm just not sure where to look ... I'm not even sure if the C library is
documented ... and which documentation is appropriate.

Information Regarding $_Session And Extract
I am new to PHP. I would need some information on the following:

1. a) I wanted to know from where the data is extracted and stroed in
the global assocoative
arrays ( specifically what will be the contents of $_Session ?)
b) Is there any way by which i can get to know all the keys of the
arrays ( specifically what
are the Keys of $_Session ?)
extract($_GET);
extract($_POST);
extract($_COOKIE);
extract($_SERVER);
#extract($_SESSION);

How To Capture Cookies Information
I want to find out how do I capture user
cookies information for traffic analysis on Windows machine and server
cookies from Linux server.

How To Capture Cookies Information
php scripting and want to find out how to capture cookies

Checking Information In An Array.
I have a function which reads a csv file into an array from there I want to
check if a value is in it.

Basically the csv files look like this:

23123233123,name,some@one.com
23423412213,name2,some2@one.com
211111,name3,some3@one.com

My function looks like this:
function read_csv($filename, $delim=',')
{
$row = 0;
$dump = array();
$f = fopen ($filename,"r");
$size = filesize($filename)+1;
while ($data = fgetcsv($f, $size, $delim)) {
$dump[$row] = $data;
$row++;
}
fclose ($f);
return $dump;
}

$csv_array = read_csv(csvfile.csv);

I would like to now seach the array to see if a value is in there and do
something from there with it.

if (in_array(211111) == "true"){
echo "Your already in the file";
//note don't write to csv file
}

When I try to check to see if the value is in there It never tells me true
so I can run the commands that I want from there.
