SESSION VARIABLE in PHP

I am new to web applications, but for what I need is to know
how to use session variables. When a user logins I want thier
information stored so when they visit my account they are able to
see thier information and not someone elses. Any help should be in
PHP format. Thank you in advance.

How to generate a random session variable in php

i want to generate a random session variable and insert the variable in a mysql record to use later to validate an account set up.
person fills out form to create account and submits; inserts form information in mysql record.
i want the random variable to be inserted from a hidden field and the page sends an email with a link to click on to compare the variable to validate the user.
Not sure how to generate a random session variable and get that to the hidden field value to be inserted with the other form information.
thanks for your help,
Jim Balthrop

To insert the key I would personally do something like...
$key = md5($username . $password . $salt);
Insert that into your MySQL database, then send them a email with it, my next code shows how to activate it.
This is to activate the account.
<?php
$key;
$errors = array();
if(isset($_GET['key']){
     $key = $_GET['key'];
     $sql = 'SELECT * FROM users WHERE key = \'' . $key '\' LIMIT 1';
     $result = mysql_query($sql) or die(mysql_error());
     if(mysql_num_rows($result)){
          $sql2 = 'UPDATE users SET active = 1 WHERE key = \'' . $key '\' LIMIT 1';
          $result2 = mysql_query($sql2) or die(mysql_error());
          if($result2){
               //successfully activated account
          else{
               //Something Went Wrong!
     else{
          $errors[] = 'Invaild Key, Please try again!';
else{
     $errors[] = 'Invaild Key, Please try again!';
?>

Creating a session variable with PHP

Can anyone offer me a PHP script that creates a session
variable? The Dreamweaver CS3 Help documentation offers coding
samples for ColdFusion and ASP but not for PHP. I tried this
without success:
"$_SESSION['usermail']= $_POST['sub_email'];" in which I am
trying to capture an email address from a form and save it to use
in a confirmation email to a new subscriber. Any help would be
sincerely appreciated.
[email protected]

I use this -
<?php
if (!isset($_SESSION)) {
session_start();
?>
at the top of the page, and then this within the code block
where you are
processing the form's data -
$_SESSION['usermail']= $_POST['sub_email'];

Accessing session variables with php

I am trying to access the session variable $_SESSION['MM_Username'] in one of my php pages, but it is somehow showing empty (i.e it does not contain the username that was entered during login).
I checked and confirmed that my login.php function is properly setting the MM_Username session variable by echoing it from the login function.
So why can't I read it from another php file in the same session? Do I need to do something else before the session variables can
be properly read from any php file in the same session? Any help would be appreciated.

Here is a test code I am using to access the session variable $_SESSION['MM_username'] from the php page test.php. But it is not working.
I get an empty string all the time for $username. Can any one see something wrong with this code?
<?php require_once('Connections/MyTestingConn.php'); ?>
<?php session_start(); ?>
<?php
$username = "-1";
if (isset($_SESSION['MM_username'])) {
$username = $_SESSION['MM_username'];
echo $username;
else
echo "Eror: can not access session variable";
?>

Passing Session Variable from PHP to Applet

I'm trying to pass a session variable from a PHP script to a third party applet. The applet needs to accept the variable as a string into a parameter. I think the htnl has to be dynamically created to turn the session variable into a string for the parameter value. Any suggestions ?

This is really a PHP question. You might get better results on a PHP forum.

Session Variables to control Datasource used by iBots

Hello everyone,
i'd like to know whether it is possible to control the session which is used by iBots.
What i want to achieve is, that i can start an iBot within a certain session with given parameters, based on session variables.
I have one SessionVariable "sDB" which can be set to =1 or =2. This is controled via the URL used to start OBIEE.
Now i want to control my ibots by forcing them to start with sDB=1 or sDB=2 etc.
Does anybody know a solution. Any hint might help aswell.
Thanks!

Thank you David for the response. As you guessed, I'm fairly new with session variables. What I'm looking for is as follows-
On my Architecture website, I have an html form where clients would enter their design preferences and Submit. The website then sends an email to the client with the details they had entered; for confirmation. This had worked properly with form variables as the email is sent right after the form is filled.
However, now I have added a License agreement page and a second form with other design details, which has to be filled in before the client's email is sent. So, I've set the Page1 form variables as session variables to carry over to the 4th page where it is sent as email. I am able to retrieve the session variables on the fourth page, but what I require is the correct syntax for using it in the subject field and the message body of the email, so that the clients get them in their email.
I had earlier used the following php code for sending emails using form variables-
    $to="From: $email";
    $subject="$name, Thank you for visiting our website.";
    $from="[email protected]";
    $msg="Your Reg. details-\r\n\n$name\r\n$address\r\n\nPhone No: $phone \r\nE mail: $email \r\n\nMessage:\n$message";
    $fla=mail($to,$subject,$msg,$from);
; where the form variables are- $name, $address, $phone, $email, $message
I have now set them as session variables-
<?php
session_start();
$_SESSION['name'] = $name;
$_SESSION['address'] = $address;
$_SESSION['phone'] = $phone;
$_SESSION['email'] = $email;
$_SESSION['message'] = $message;
?>
; and I'm being able to retrieve them on the 4th subsequent page. As mentioned, what I am looking for is the correct syntax to use this data in a php email code.
I will be very grateful if you could provide me with a sample php email code for sending an email with session variables in the 'from', 'to', 'subject' and 'message' fields.

Help with session variable please - CS5.5 PHP

Hi all,
I am needing a little assistance with using a session variable and hope that someone may point me in the right direction.
I have created a PHP page that uses the Dreamweaver 'User Authentication' feature, and the basics of this works fine, directing a user to the correct pages depending on whether they are or are not a valid user. I would like however to personalise the 'valid user' page with the persons Username as entered in the User Authentication table....a seemingly simple task using a session variable, but one that I just don't seem to be able to get working!
The code generated for the UA on page 1 is as follows:
<?php
// *** Validate request to login to this site.
if (!isset($_SESSION)) {
session_start();
$loginFormAction = $_SERVER['PHP_SELF'];
if (isset($_GET['accesscheck'])) {
$_SESSION['PrevUrl'] = $_GET['accesscheck'];
if (isset($_POST['txtfirst_name'])) {
$loginUsername=$_POST['txtfirst_name'];
$password=$_POST['txtsurname'];
$MM_fldUserAuthorization = "";
$MM_redirectLoginSuccess = "member_update.php";
$MM_redirectLoginFailed = "login.php";
$MM_redirecttoReferrer = false;
mysql_select_db($database_panto, $panto);
$LoginRS__query=sprintf("SELECT firstname, surname FROM web_access WHERE firstname=%s AND surname=%s",
    GetSQLValueString($loginUsername, "text"), GetSQLValueString($password, "text"));
$LoginRS = mysql_query($LoginRS__query, $panto) or die(mysql_error());
$loginFoundUser = mysql_num_rows($LoginRS);
if ($loginFoundUser) {
     $loginStrGroup = "";
    if (PHP_VERSION >= 5.1) {session_regenerate_id(true);} else {session_regenerate_id();}
    //declare two session variables and assign them
   $_SESSION['MM_Username'] = $loginUsername;
    $_SESSION['MM_UserGroup'] = $loginStrGroup;
    if (isset($_SESSION['PrevUrl']) && false) {
      $MM_redirectLoginSuccess = $_SESSION['PrevUrl'];
    header("Location: " . $MM_redirectLoginSuccess );
else {
    header("Location: ". $MM_redirectLoginFailed );
?>
Firstly, the text highlighted in red above appears to be setting the session variable that I require. Is This correct?
If so, what is the code that I need to place in page 2 to use that session variable? or
Do I need to do something else on page 1 to properly assign the session variable?
Would really appreciate your expertise
Mark

It looks as though you've set the columns incorrectly in the User Authentication server behavior. This is the SQL query that checks the user's credentials:
$LoginRS__query=sprintf("SELECT firstname, surname FROM web_access WHERE firstname=%s AND surname=%s",
    GetSQLValueString($loginUsername, "text"), GetSQLValueString($password, "text"));
You're looking for firstname and surname, whereas you should be looking for the user's login name and password.
$_SESSION['MM_Username'] is a session variable that stores the user's login name. To use it in a subsequent page, all that's needed is for the page to begin with session_start(). You can then echo the value to display it.
If you want to display the person's real name, you need to create a recordset in the second page using $_SESSION['MM_Username'] to find the firstname and surname. Alternatively, you can edit the existing code like this (I've copied only part of it):
$LoginRS__query=sprintf("SELECT firstname, surname FROM web_access WHERE firstname=%s AND password=%s",
    GetSQLValueString($loginUsername, "text"), GetSQLValueString($password, "text"));
$LoginRS = mysql_query($LoginRS__query, $panto) or die(mysql_error());
$loginFoundUser = mysql_num_rows($LoginRS);
if ($loginFoundUser) {
     $loginStrGroup = "";
    $row = mysql_fetch_assoc($LoginRS);
     $_SESSION['full_name'] = $row['firstname'] . ' ' . $row['surname'];
    if (PHP_VERSION >= 5.1) {session_regenerate_id(true);} else {session_regenerate_id();}
    //declare two session variables and assign them
   $_SESSION['MM_Username'] = $loginUsername;
    $_SESSION['MM_UserGroup'] = $loginStrGroup;
You can then use $_SESSION['full_name'] in a subsequent page that begins with session_start().

Session variables in jsp,php

You can create POST or GET request.

Accessing session variables PHP

I am trying to access a session variable from a log in form (using the Log In User Server Behavior) and am lost. I simply want to display the users information in the target page. I read in another discussion that I had to bind the variable to the target page, which I did, but that didn't fix it.
Please help.
Here is my loginFormAction code:
<?php
// *** Validate request to login to this site.
if (!isset($_SESSION)) {
session_start();
$loginFormAction = $_SERVER['PHP_SELF'];
if (isset($_GET['accesscheck'])) {
$_SESSION['PrevUrl'] = $_GET['accesscheck'];
if (isset($_POST['email'])) {
$loginUsername=$_POST['email'];
$password=$_POST['password'];
$MM_fldUserAuthorization = "";
$MM_redirectLoginSuccess = "owner.php";
$MM_redirectLoginFailed = "register.php";
$MM_redirecttoReferrer = false;
mysql_select_db($database_petriever, $petriever);
$LoginRS__query=sprintf("SELECT email, password FROM owners WHERE email=%s AND password=%s",
    GetSQLValueString($loginUsername, "text"), GetSQLValueString($password, "text"));
$LoginRS = mysql_query($LoginRS__query, $petriever) or die(mysql_error());
$loginFoundUser = mysql_num_rows($LoginRS);
if ($loginFoundUser) {
     $loginStrGroup = "";
    //declare two session variables and assign them
    $_SESSION['MM_Username'] = $loginUsername;
    $_SESSION['MM_UserGroup'] = $loginStrGroup;
    if (isset($_SESSION['PrevUrl']) && false) {
      $MM_redirectLoginSuccess = $_SESSION['PrevUrl'];
    header("Location: " . $MM_redirectLoginSuccess );
else {
    header("Location: ". $MM_redirectLoginFailed );
?>

Wherever you want to display the logged-in username simply place this on the first line of a .php page to start the session:
<?php session_start(); ?>
Then place this code wherever you want to display the username:
<?php echo $_SESSION['MM_Username']; ?>

Help with php session variables

I am using Dreamweaver 8 to set up a dynamic app with PHP and
MySQL. I want the code that the user logs in with ('UPN') to be
stored as a session variable so that recordsets on subsequent pages
can be set to display personalised data.
I have set the session variable like this: $_SESSION['UPN'] =
'UPN' (UPN is the name of the form textfield, also set as the
username for logging in)
On the data page, I have called the variable like this:
$query_Recordset1 = ("SELECT pupils.pupilID, pupils.UPN,
pupils.forename, pupils.surname FROM pupils WHERE UPN = '" .
$_SESSION['UPN'] . "'");
The recordset returns nothing- the dynamic table returns ony
the column headings (both as headings and immediately under where
you would expect the data to be).
Can anyone help?
Thanks

Your code assigns the literal string UPN to the session
variable. If
it's coming from POSTed form data, you'd need to do it like:
$_SESSION['UPN'] = $_POST['UPN'];

Retrieving a session variable from a php script and putting it in an applet

I have a chat applet and i'm trying to have a session variable in one my php scripts be setted onto the user area of my chat. Would it start out by doing this?
<object codetype="application/java"
code = "ClientApplet.class"
width = "300"
height = "400"
classid = "the name of the session variable">
</object>

No.
Use the parameter tags.

PHP Session Variable

When using the PHP variable $_SESSION['idk'], what is the significance to the string 'idk'?
I have been playing around with a login script, and I have seen some people throw 'user_login' or 'login' or 'user' and I figured it was just a way of labeling it essentially. But then I happened across a post where someone was generating and using a random string with the Session variable.
Does this string have to be different for every user logging into a website? If not, what is the purpose of generating a random string to use in conjunction with the Session variable?
Maybe any insight into different uses of the Session variable would be helpful as well.
Thanks!

Servlet/PHP Session Variables

Hello Everyone,
I am running an servlet that requires authentication. The authentication is done by a PHP program, while the heavy lifting is done by a servlet. How do I pass a session variable from my php to my servlet so that my servlet knows the user is allowed. I have tried
Object done = session.getAttribute("loggedIn");
with "loggedIn" being set by my php file, but done is always null. Any help is greatly appreciated especially if it is cookie free.
Sincerely,
Chem E

You could consider the following solution: on click of the link, fire a specific Ajaxical request from the server where PHP runs to the server where Java runs to obtain an lengthy and unique key which expires within a few seconds, use JS+DOM to add that key as a query parameter to the link value and after opening the link let the Java side determine the key and handle accordingly.
You only need to write code so that it is hack safe.

Session variable not storing in custom trigger

I have a custom trigger in which I want to store a session variable , so i can use the value in the insert transaction which happens after. But for some reason the session variable is not stored, resulting in the data not being stored.
any clues would help.
rudi
here are the relevant code:
//start Trigger_Custom_Subject_Mentor trigger
function Trigger_Custom_Subject_Mentor(&$tNG) {
//Check subject exists
@session_start();
$_SESSION['sb_id'] = $subject_id;
//end Trigger_Custom_Subject_Mentor trigger
// Make an insert transaction instance
$ins_share = new tNG_insert($conn_smart);
$tNGs->addTransaction($ins_share);
// Register triggers
$ins_share->registerTrigger("STARTER", "Trigger_Default_Starter", 1, "POST", "KT_Insert1");
$ins_share->registerTrigger("END", "Trigger_Redirect", 90);
// Add columns
$ins_share->setTable("`share`");
$ins_share->addColumn("share_item", "NUMERIC_TYPE", "POST", "share_item");
$ins_share->addColumn("share_subject", "NUMERIC_TYPE", "SESSION", "sb_id");
$ins_share->setPrimaryKey("share_id", "NUMERIC_TYPE");
// Register triggers
$ins_share->registerTrigger("STARTER", "Trigger_Default_Starter", 1, "POST", "KT_Insert1");
$ins_share->registerTrigger("BEFORE", "Trigger_Custom_Subject_Mentor", 50);
$ins_share->registerTrigger("END", "Trigger_Default_Redirect", 99, "share.php?item_id={share_item}");

hi User,
1) Pull a dummy column in Fx use the Session variable --->(Variable -->session )
2) Next, goto narrative view in Narrative view section use @1
3) If u want you can hide the column that we created in criteria section

Unable to filter a recordset using a session variable

I have a volunteer application page and when the volunteer presses <Submit> their info is saved in a MySQl db table and a session variable is created containing the primary key of their record in the table, control is then passed to a "success page". The success page can access the session variable (I proved this by displaying the session variable on the success page) so my next step was to create a recordset in the success page with a filter using the session variable to select the appropriate row in the table, allowing me to display to the volunteer the info they submitted.
I set up a test success page which displays the session variable and one field of the volunteer info. When I test this I see the session variable displayed but the corresponding volunteer info field from the recordset is not displayed.
The volunteer application page is here www.hollisterairshow.com/volunteerapp.php and the successpage is here www.hollisterairshow.com/thanksvol.php
The code that creates the session variable in the volunteer application page is shown below
$_SESSION['volunteer_id'] = mysql_insert_id();
The code to display the session variable in the success page is shown below
<?php echo $_SESSION['volunteer_id']; ?>
The code to display the volunteer info is shown below
<h1> Thank You <?php echo $row_rsVolunteerApp['firstname']; ?>!! </h1>
The recordset definition is shown below
The success page test result is shown below, as you can see the volunteer's first name is not displayed immediately after the "Thank you" message but the session variable holding the correct primary key (41) is shown correctly.
Does anyone have an idea of what I'm doing wrong?
Thanks
Tony

Where did you put session_start()? It needs to be before the variable is accessed. It's obviously before the line that displays the value in your page, but is it before the SQL query is generated?
Also, have you checked in phpMyAdmin to see whether volunteernumber 41 has any values in the database?
