I Need Help With A Log-out/session Issue	View Content

I'm using the PHPmotion script, with a use-a-credit to view-a-video mod. When the user logs out, the viewed video should not be available again to view, until he logs back in and chooses it chooses it, via a credit, but it is still available when he logs back in. Any ideas on what file may be responsible for what I guess you could call 'clearing the session'?

Issue With Session Variables

Similar Tutorials

About to pull my hair out. Looks simple, I think it's simple, but something is not behaving. I have a simple login page (loginpage.php) which checks a database for the FamilyID and Password, if it is a match, then it redirects them to userspage.php. I eventually want to use the FamilyID as a filter for my database so I only show the stuff relative to that FamilyID. Using CS5 and the built in functions, and it looks to me that the session variable 'MM_Username' should contain the FamilyID which is "adminid" in my database. It appears to work since it sends me to my userspage.php when I enter a valid FamilyID and Password, but it will not show me my session variable on the that page!!! PLEASE PLEASE HELP...Slap me in the face if it's a stupid question, but I have spent WAY too much time trying to figure what is wrong. I have included my code:

CODE FOR LOGINPAGE.PHP

Session Timeout Issue

Similar Tutorials

I have 500 users using software I have developed, and 495 do not have a timeout problem. Our default is to timeout after 60 minutes, but one particular office times out randomly and without warning. The normal procedure is, like online banking, a pop up comes up to let them know they will be logged out in 60 seconds, or they can click continue to stay logged in. The timer is based on JS, but on each page load a PHP function checks to see if they are timed out, and if they are, redirect them to the login page. The JS pop up never occurs, so obviously the countdown hasn't happened, but when they click on a link, they are redirected to the login page. Since the issue only occurs in one office, it leads me to believe it is a firewall or anti-virus issue, but I'm not sure... Anyone have any thoughts on this?

Session_set_save_handler & Session Issue

Similar Tutorials

I'm having an issue with sessions and session_set_save_handler.
Note: new at OO PHP

I'm using an MVC written mostly from a tutorial and it all seems to be working, except for sessions.
I've got session_set_save_handler as a class SessionHandler. If I include it into the main index page and create an instance, I get an error 'Undefined variable: _SESSION' for my index view file.
If I instead include a global.php file into the main index page and include the session class into the global.php page, and create an instance, the error goes away and session_set_save_handler saves the session variables into my database.

(1)On my index page for debugging I've got a var_dump of $_SESSION to see which session variables are set.

On my login page I've got a form token that is saved to a session variable. When I go to the login page that session token variable is set and doing a var_dump on the page shows it is indeed being set, however, when I click back to the main index page, the index var_dump(1) shows the session variable is no longer set.
But then if I login it correctly redirects me to a user logged in page and echos the username of the user logged in correctly, but still does not show the form token session variable in the var_dump for index(1). But then if I navigate to the login form page where the form token should be initially set, it now sets it correctly and going to the index page indeed shows the token set.

form token being set on login view page:

Code: [Select]
$login_token = $_SESSION['login_token'] = md5(uniqid(mt_rand(),true));
var_dump on index page before login (even if I navigate to login page then back to index it remains blank when it should instead show the form token session variable)
Code: [Select]
array
empty
var_dump on index page after login.
Code: [Select]
array
'lu_user' => string 'admin' (length=5)
'lu_user_id' => string '6' (length=1)
'user_sess_time' => int 1326544148

var_dump on index page after login, navigating to login form page (where login_token is set), then navigating back to index:

Code: [Select]
array
'lu_user' => string 'admin' (length=5)
'lu_user_id' => string '6' (length=1)
'user_sess_time' => int 1326544148
'login_token' => string 'c260e76dd65f0d9b6e881cfc9a4b33e1' (length=32)
Magically the login_token now shows, but only after logging in and setting the other variables. It seems it's not saving the login_token when it's initially set, but only after logging in which it shouldn't be doing.

The same issue arises with any other session variables that I set elsewhere (only displayed after user login).

If I remove session_set_handler the sessions set correctly but naturally the data is no longer added to the database.

If I do var_dump(get_included_files()); it shows the session class is correctly being included.
I was thinking it's an issue with session_start() but if I add that in or try to create another instance of the session class on the other pages, I get an error stating they've already been called and cannot be called again. So then they must be getting called, right?

So now I'm thoroughly confused. More code below, sorry for the long post. Hopefully I've provided all necessary information.

Index includes global.php, which contains:

Code: [Select]
require 'framework/SessionHandler.php';

$sess = new SessionHandler();

And the session handler class is (Database class is included into index which is why you cannot see it instantiated here):

Code: [Select]
<?php

class SessionHandler
{
function __construct()
{
session_set_save_handler
(
array(&$this, 'open'),
array(&$this, 'close'),
array(&$this, 'read'),
array(&$this, 'write'),
array(&$this, 'destroy'),
array(&$this, 'gc')
);

session_start();

ini_set('session.gc-maxlifetime', 1800);

if (isset($_SESSION['lu_user']))
{
if (!isset($_SESSION['user_sess_time']))
{
$_SESSION['user_sess_time'] = time();
}
elseif (time() - $_SESSION['user_sess_time'] > 1800) // 30 mins
{
    session_regenerate_id(TRUE);
    $_SESSION['user_sess_time'] = time();
}
}
}

function open()
{
$this->db = new Database();
}

function close()
{
return $this->db = null;
}

function read($id)
{
$stmt = $this->db->prepare('SELECT * FROM sessions WHERE id = :id');
$stmt->execute(array(':id' => $id));

if ($row = $stmt->fetch(PDO::FETCH_ASSOC))
{
return $data = $row['data'];
}
else
{
return '';
}
}

function write($id, $data)
{
$access = time();

if (isset($_SESSION['lu_user']))
{
$session_id = session_id();
$username = $_SESSION['lu_user'];

$stmt = $this->db->prepare('REPLACE INTO sessions (id, access, data) VALUES (:id, :access, :data)');
$stmt->execute(array(':id' => $id, ':access' => $access, ':data' => $data));
}
}

function destroy($id)
{
if (ini_get("session.use_cookies"))
{
     $params = session_get_cookie_params();
     setcookie(session_name(), '', time() - 42000,
         $params["path"], $params["domain"],
         $params["secure"], $params["httponly"]);
}

$stmt = $this->db->prepare('DELETE FROM sessions WHERE id = :id');
$stmt->execute(array(':id' => $id));
}

$old = time() - $max;

Member Only Session Issue

Similar Tutorials

Hi guys i've spent 3 whole days trying to get this to work but it dosent. My issue is very similar almost the same as: http://www.phpfreaks.com/forums/index.php?topic=296100.15 but with the code i have.

Basically i have custom member pages. member1.php member2.php the design and content will be custom to each member, they also have their own login page.

Each member should be able to access their page and simply view their secure area. They should not be able to log into another users area if they dont have the username or password for it.

Now the problem is, i have this entire script setup and it works, however i fear there is something wrong with the sessions which allows other members to access other members pages with their own passwords and usernames because they share the same database. So the script executes thinking its a valid user and lets them in.

Here is my login checker once the user is validated they are sent to their own folder header("Location: ../{$loginusername}/index.php"); and are able to view the page.

Code: [Select]
<?php
require_once('../config.php');

// Connect to the server and select the database.
mysql_connect("$host", "$username", "$password")or die("cannot connect");
mysql_select_db("$db")or die("Unable to select database");

// The username and password sent from login.php
$loginusername=$_POST['username'];
$loginpassword=$_POST['password'];

//The following bit of coding protects from MySQL injection attacks
$loginusername = stripslashes($loginusername);
$loginpassword = stripslashes($loginpassword);
$loginusername = mysql_real_escape_string($loginusername);
$loginpassword = mysql_real_escape_string($loginpassword);

$sql="SELECT * FROM $tbl WHERE username='$loginusername' and password='$loginpassword'";
$result=mysql_query($sql);

// Count how many results were pulled from the table
$count=mysql_num_rows($result);

// If the result equals 1, continue
if($count==1){

session_start();
$_SESSION["loginusername"] = $loginusername;
$_SESSION['user1'] = $username; // store session data
//echo "User: = ". $_SESSION['loginusername']; //retrieve data
header("Location: ../{$loginusername}/index.php");

}
// If not successful, inform the user of error
else {
echo "Wrong Username or Password";
}
?>

Now here is the secure page sample:

Code: [Select]
<?php
session_start();
if (!$_SESSION['user1']){
header("Location: login.php");
}else{
print "its working!";
}

?>

<html>
<body>
Login Successful for

</body>
</html>

For each login page i have given each user it's own session.. this works, however if user1 logs in and simply changes the url to user2 and enters his user2 password he is granted access giving him new sessions which means he has access to everything.

Im pretty sure im missing something really small any help would be appreciated.

Session Protection Issue's

Wierd Session Issue

Similar Tutorials

Hi Everyone

I have a weird session issue going on and i'm not sure what is causing it.

Basically any sessions that i set are randomly expiring sooner than they should be. As a test I did the following:

Code: [Select]
<?php
session_start();
if(isset($_SESSION['views'])){
$_SESSION['views'] = $_SESSION['views']+ 1;
}else{
$_SESSION['views'] = 1;
}
echo "views = ". $_SESSION['views'];
echo '<p><a href="testpage.php">Refresh</a></p>';

?>

If i continue to click the refresh button, i sometimes get to 30 and then it starts at 1 again. Other times ill get to 20 and then back to 1. It has also sometimes skips a couple of counts from 7 to 11 as an example in one click.

Any one come across this before?

I have been reading up online and some have mentioned PHP upgrades from php4 to php5 cause some issues and specifically the hosting company changing the session.save_path.

If this was the case, it wouldn't even count to 10, would it?

Any help would be really appreciated.

thanks in advance

Session Array Issue

Similar Tutorials

Hi All,

I'm running trying to add key and values to an array on multiple pages, but it seems to override the array each time I add variables on the next page, even though the keys are different.

Each page has something like this:

Code: [Select]
<label class="yes"><input type="radio" name="form_field[<?php echo "number".$f1; ?>]" value="0" > Yes</label>
<label class="no"><input type="radio" checked="checked" name="form_field[<?php echo "number".$f1; ?>]" value="1" > No</label>
<label class="unsure"><input type="radio" name="form_field[<?php echo "number".$f1; ?>]" value="2" > Unsure</label>
I then collect it as well as other page variables with:

Code: [Select]
session_start();

foreach($_POST as $name => $value) {
$_SESSION[$name] = $value;
}
on all following pages. But rather than adding to the array it writes over it each time.

Any ideas on what's going wrong here. Should the array simply be able to continue to collect the keys or do I need to do something else?

Thanks.

Php Session Issue With $password On Input

Similar Tutorials

I am having a very strange issue on one server. I have the same code in a development server running fine, but in my prod server it is failing. Here is the main issue:

I have a user authentication routine that accepts UserID and Password from a form and validates it against a MySQL database. So to start, UserId and Password are entered via POST variables as is standard:

$UserId=@$_POST['UserId'];
$Password=@$_POST['Password'];

The Password is encrypted using a standard crypt method such as:

$encrypt = crypt($Password,'6!68$7435!');

And this is stored in a MySQL database. This part is working fine, that is, the password is encrypted in value and stored in the MySQL database as 'epasswd'. On login, I am using session, so a standard session_start() and eventual session_destroy() on logout are used. The reason I mention this is because I suspect my issue is session related.

So normally this works well. User logs in and I check credentials as follows in one part of my auth routine:

elseif(UserAuth($UserId,$Password)){
    $UserLogin=$UserId; session_start();
    $_SESSION['UserLogin'] = $UserLogin;
    sql_insertActivity();
    header("Location: home.php");

And the auth routine is as follows:

<?

function UserAuth($UserId,$Password){
global $conn;
$Stmt="select epasswd from Users where UserId='$UserId' and Approved='1' or Approved='-1' or Approved='-2'";
$Result = mysql_query($Stmt, $conn) or die(mysql_error());
$Result=mysql_fetch_row($Result);
$epasswd=$Result[0];
$retval=($epasswd==crypt($Password,$epasswd));
return($retval);
}
?>

So I am checking for a valid UserID and Password on form input, and I have a few other variables set for approved status. The retval checks the password they enter versus the encrypted value for a match. This usually works well. Then login occurs and session started, etc.

Here is the issue. I added a quick admin routine a little while ago which helps reset a user's password to a temporary value. Once this value is set, along with a setting of approved=-1 in my database, then the user is re-directed to a Change Password screen to update his or her password. *Note: I changed the value to 'Charlie' for this discussion purpose. Here is that quick admin routine I run when I need to change a User to a temp setting:

// ----- Establish database connection -----
require "../inc_php/inc_mysql_prod.php";

//

$UserId=@$_GET['UserId'];
$Password='Charlie';
$encrypt = crypt($Password,'6!68$7435!');
$sql = "UPDATE Users set epasswd='$encrypt', approved='-1' where UserId='$UserId'";
mysql_query($sql, $conn) or die(mysql_error());

So this does work as I validate the UserID is updated in the MySQL database along with an encrypted value for 'Charlie'.

However, this is where things breakdown going forward. When the user logs in with the temp credentials, and enters in the Change password routine, their new password is saved in the table. However, when logging back in with the new credentials, the new password is not valid. And what's odd is that 'Charlie', the temp password, works for them on login and nothing else, no matter how many times they change the password in the form.

So seems a case of session management out of control? What is the issue? I am defining session on all Php pages used, and have a logout to destroy session, etc. The temp password routine is something I run as an admin in the system and it doesn't have a session start statement. And I am not defining any global vars for Password. I lloked into session management and tried some UNSET paths and such, but may not be doing this correctly. Also I did a complete stop apache, remove all php sess_ files, restart and to no avail. I tried the clear my client side cookies deal in the browser, and still the same problem.

What is odd is that this same set of code works fine on my other server, but breaks down on the mirrored server. They are essentially twins in all setup. Some minor differences between the two servers regarding PHP setup that might(?) make a difference.

DEV server:

SERVER_SOFTWARE Apache/2.2.3 (Red Hat)

PROD server: (server showing the issues):

SERVER_SOFTWARE Apache/2.2.3 (CentOS)

HTTP_COOKIE PHPSESSID=3gocr0hhelvsjjlt63pp4qlnp3

_SERVER["HTTP_COOKIE"] PHPSESSID=3gocr0hhelvsjjlt63pp4qlnp3

Thanks appreciate the help!

Session Issue With Xampp Server.

I have a website uploaded onto Host Gator hosting and the sessions are carried over to the other pages ok.
When using the same website in XAMPP it does not carry over the session to the next page and need to login again.

If i log in it puts the following after the URL - ?sid=3b71942d410d84c45f9f4433561c325a
The when i go to another link it loses the sid and i'll need to manualy past it into the next URL to get it working unless i log in again on the new page.

This is only happening with XAMPP but working fine in the Host Gator hosting environment.

Warning: Session_start() [function.session-start]: Cannot Send Session Cache

Similar Tutorials

I am having trouble resolving an error.

Warning: session_start() [function.session-start]: Cannot send session cache limiter - headers already sent (output started at /home/s519970/public_html/header.php:27) in /home/s519970/public_html/admin/login.php on line 2

What I can gather is I can't use "header (Location: 'admin.php')" after i've used session_start(). I have tried to replace the header (Location: 'admin.php') with this:

echo "<script>document.location.href='admin.php'</script>";
      echo "<script>'Content-type: application/octet-stream'</script>";

I've been trying to read up on solutions but haven't been able to get it sorted. If anyone can offer some advice that would be greatly appreciated as im new to php.

Code: [Select]
<?php
  session_start();
  if(isset($_SESSION['user']))

                echo "<script>document.location.href='admin.php'</script>";
echo "<script>'Content-type: application/octet-stream'</script>";
?>

<div id="loginform">

<form action="dologin.php" method="post">
<table>
<tr>
<td><span>Username:</span></td>
<td><input type="text" name="username" /></td>
</tr>
<tr>
<td><span>Password:</span></td>
<td><input type="password" name="password" /></td>
</tr>
<tr>
<td colspan="2" align="right"><input type="submit" name="login" value="Login" /></td>
</tr>
</table>
</form>

</div>
I have tried using require_once('yourpage.php'); before my <head></head> tags in the header document where I've specified the html information but this doesn't seem to work. I've been advised to use ob_start("ob_gzhandler"); but I am not sure how to implement this.

Any advice is greatly appreciated!

Create Session And Pass Session To Iframe

Similar Tutorials

hi everyone.

i'm wondering what the best way is to create a session variable and pass it to an iframe.
i need to do something along these lines, but it doesn't seem to pass the ID. Any hints on how i should accomplish this?

Code: [Select]
session_start();
$_SESSION['ID']=$_GET['ID']; // id from previous page
$ID=session_id();

<iframe src="iframepage.php?ID=<?php echo $ID; ?>" style="width:680px; height:200px;" noresize="noresize" frameborder="0" border="0" scrolling="Yes" allowtransparency="true" /> </iframe>

How To Prevent Session Spoofing And Session Hijacking?

Similar Tutorials

I'm making a simple login system with MySQL and PHP (very simple, I'm just starting with PHP). The MySQL portion is done, but I need to ensure only people who are logged in can see certain content.

To check if people are logged in, my website checks that they have the $_SESSION['user'] variable set. If it is set, then it lets them continue through the website, if not, it tells them to login. Is that enough security, or can people simply inject a session cookie into their browser to spoof that they are logged in?

My idea was to generate a session key cookie when they login (just a random string of letters and numbers) and store that in the database, then on every page, check to make sure their session key is the same thing that's in the database. Is this necessary? It seems expensive.

Checking If 1 Session Is Active If Not, The Other Session.

Evening!

I've been iffing and ahhing over this and well im not too sure, hence the post.

Code: [Select]
// Redirects if there is no session id selected and echos the error on the previous page
if(!isset($_GET['get']) || ($_GET['getget'])){
header("Location: #.php?error");
}
So it should simply check if get is set if it isnt then see if getget is set?

If not redirect and show the error.

Now ive tried it and even when get/getget is set it still redirects, probably something silly. Care to share anyone?

Mysql Query Vs. Session / Get Vs Session?

Similar Tutorials

Just curious how other people feel about this. I am working on an application where a lot of info is pulled from MySQL and needed on multiple pages. Would it make more sense to... 1. Pull all data ONCE and store it in SESSION variables to use on other pages 2. Pull the data from the database on each new page that needs it I assume the preferred method is #1, but maybe there is some downside to using SESSION variables "too much"? Side question that's kind of related: As far as URLs, is it preferable to have data stored in them (i.e. domain.com/somepage.php?somedata=something&otherdata=thisdata) or use SESSION variables to store that data so the URLs can stay general/clean (i.e. domain.com/somepage.php)? Both are probably loaded questions but any possible insight would be appreciated. Thanks! Greg

Php Mysql Output Issue Probably A { Issue

Similar Tutorials

Hi, I have this code below which groups all the SubHeading together and then queries the same table to find RiskConsequence which are grouped that match SubHeading then to query this table one more last time with all the Risk Mitigation that matches the grouped RiskConsequence.

Problem I get is it does the SubHeading, the RiskConsequences it only does one of them not all of them before it moves onto the RiskMitigation.

I know I have a php coding issue just cant see the wood from the tree's as the queries work.

Code: [Select]
<?php
include ("include.php");
$query = "SELECT * FROM tblriskassessmentdatabank GROUP BY SubHeading";
$results = mysql_query($query) or die("Error: " . mysql_error());
while($row1 = mysql_fetch_array($results)){


    echo'<a href="#" onClick="return(changeDisplay(';echo"'";echo($row1[SubHeading]);echo"'))";echo'">';echo($row1[SubHeading]);echo'</a><br /><br />';
echo'<div id="';echo($row1[SubHeading]); echo'" class="HideText">';

$risksub = $row1[SubHeading];

$query1 = "SELECT * FROM tblriskassessmentdatabank GROUP By RiskConsequence";
$results1 = mysql_query($query1) or die("Error: " . mysql_error());
while($row2 = mysql_fetch_array($results1)){

echo'<a href="#" onClick="return(changeDisplay(';echo"'";echo($row2[RiskConsequence]);echo"'))";echo'">';echo($row2[RiskConsequence]);echo'</a><br />';
echo'<div id="';echo($row2[RiskConsequence]); echo'" class="HideText">';
$risksub1 = $row2[RiskConsequence];
$query1 = "SELECT * FROM tblriskassessmentdatabank WHERE RiskConsequence = '$risksub1'";
$results1 = mysql_query($query1) or die("Error: " . mysql_error());
while($row3 = mysql_fetch_array($results1)){

echo'<input name="checkbox[]" type="checkbox" id="checkbox[]" value="';echo($row3[IssueNumber]);echo'" />
    <label for="checkbox[]"></label>';echo($row3[RiskMitigation]);echo'<br /><br />';
}
echo'</div>';

}

echo'</div>';

Was This A Php Issue Or An Html5 Drop Down Issue ?

Similar Tutorials

Folks,

I remember once having a php or html5 issue where the first option had to be blank in the drop down. Otherwise, it wasn't working.

What wasn't working ? How wasn't working ? I can't remember. either php had difficulty reading user input or the drop down was not showing any options. And so, I had to add a blank value.

So, something like this wasn't working ...

	<label for="tos_agreement">Agree to TOS or not ?</label>
<select name="tos_agreement" id="tos_agreement">
<option value="yes">Yes</option>
<option value="no">No</option>
</select>

And, I think I added a blank value, at somebody's advice, to get it to work. I think it was something like this, if I remember correctly:

	<label for="tos_agreement">Agree to TOS or not ?</label>
<select name="tos_agreement" id="tos_agreement">
	<option value=" ">Select here</option>
<option value="yes">Yes</option>
<option value="no">No</option>
</select>

Or, maybe it was something like this:

	<label for="tos_agreement">Agree to TOS or not ?</label>
<select name="tos_agreement" id="tos_agreement">
	<option value=" "></option>
<option value="yes">Yes</option>
<option value="no">No</option>
</select>

I can't remember. All I remember slightly that there was a blank value.

I been going through my php files to find that particular file to jog my memory but I failed to find it.

Can you folks explain to me if a blank value is required or not ? What is the benefit/disaster of adding it and how should the blank value be added ? Show me an example.

Was this a php or html 5 issue ? Can anybody fugure ?

Thank You
