PHP - Session Lost Problem Its Urgent

Hi Guys,

I am developer and relatively new to php although I have written a few scripts. I have a site which runs on linux/unix platform.

I am facing a weird problem:

- I have a php script (e.g. site.com/test/test.php) which takes a input from url, and creates a session and opens a wordpress php in another folder (e.g. site.com/wp/index.php)
- I wrote a small php code in that wp/index.php which checks if session exists or not. if yes, then no problem, if not then die and show a message.

Now the problem is when I run the script, it opens the wp/index.php and the page opens. Good. But when I click on any link in that page e.g about or so, then I get message which I wrote that session not found and so on...

I don't know why this is happening.

So if you guys can help me with this it would be great. Alternatively, I thought if I protect the wp folder (using protect folder thru cpanel) and write a php script outside which call the php inside the wp folder with a hardcoded uname & pw, then i can run the php inside without anyone knowing what the actual uname or pw is. This way if a user directly tries to access it , he wont be able to do so as uname & password box will appear.

But I dunno how to call a php inside protected folder. I tried to redirect but the uname & pw box appeared.

I would be grateful if anyone can help me.

Thanks a lot,

Cheers,
GR

I'm writing a shopping cart type of application for booking something. The cart will holds items as arrays in the session. The problem i'm i'm having is i can store 5 items in my cart and then once i try to store any more, it just won't. I'm not getting any php errors. I'm using the codeigniter framework, so it may be a codeigniter session storage problem. Hopefully you guys can look at it and can see if you spot any bad logic that i'm overlooking.

Code: [Select]
<?php
                 //generates random unique 32 character string
$booking_hash = random_string('unique');

//set items foreach night
foreach($room['date_rate'] as $date => $rate)
{
                        //produces random sha1 16 char length string
$sha1 = random_string('sha1', 16);

$session['items'][$sha1] = array(
'code'       => $room['code'],
'id'         => $room_id,
'title'      => $room['title'],
'date'       => date("n/j/Y",strtotime($date)),
'price'      => $rate,
'tax_one'    => money_format('%i',$room['tax_one'] * $rate),
'tax_two'    => money_format('%i',$room['tax_two'] * $rate),
'sales_tax'  => 0,
'guests'     => $num_guests,
'booking'    => $booking_hash,
'deposit'    => $deposit,
);
}


$existing_items = $this->session->userdata('items');

   if(!empty($existing_items))
  {
$session['items'] = $existing_items + $session['items'];
    }
 
$this->session->set_userdata($session);


?>
I just read some codeigniter session documentation. It says the cookie it's using can hold 4KB of data. I have no idea how much text 4KB can hold...

This is my first post here. G'day everyone. I'm having trouble with getting a session recognized from one page to another. I did a search and used the advice but I'm still having trouble.

I have a page called checklogin.php that processes the information submitted for a member to login, and redirect it to login_success.php if the login was successful.
The problem I have is when I test the session in the second page it tells me there is no session. Here's my code (I omitted the db connection code):

Code: [Select]
<?php
// username and password sent from form 
$myusername=$_POST['user']; 
$mypassword=$_POST['pass'];
?>

<?
// Mysql_num_row is counting table row
$count=mysql_num_rows($result);
// If result matched $myusername and $mypassword, table row must be 1 row

if($count==1){
// Register $myusername, $mypassword and redirect to file "login_success.php"

$_SESSION['myusername']=$myusername;
$_SESSION['mypassword']=$mypassword;
header("location:login_success.php");

}
else {
echo "Wrong Username or Password";
}
?>


after I am redirected to login_success.php:

Code: [Select]

<?php
session_start();
$_SESSION['myusername'];

if (isset($_SESSION['myusername']))
{
$loggedin = TRUE;
return $loggedin;
echo "logged in.";

}
else
echo "not logged in";
?>

It echoes "not logged in". I've struggled with this for days and I don't know what's wrong. Thanks in advance.

I have this error, and I cann't find soluiton:
Code: [Select]
Notice: Undefined index: ime in C:\wamp\www\web\login_public.php on line 26

Notice: Undefined index: ime in C:\wamp\www\web\login_public.php on line 27
This is the code:
Code: [Select]
<?php require_once("public/includes/session.php"); ?>
<?php require_once("public/includes/connection.php"); ?>

<?php  

if(!$_POST['submit']){
header('refresh:0; url=index.php');}
else {
$korisnik = $_POST['korisnicko_ime']; 
$lozinka = $_POST['lozinka'];
$lozinka_db = sha1($lozinka);

if ($korisnik && $lozinka){
$query = mysql_query("SELECT * FROM korisnik WHERE korisnicko_ime = '$korisnik' ");
$numrow = mysql_num_rows($query);

if($numrow != 0){

while ($row = mysql_fetch_assoc($query)){
$korisnik_db = $row['korisnicko_ime'];
$db_lozinka = $row['lozinka'];
$ime = $row['ime'];
}
if ($korisnik == $korisnik_db && $lozinka_db == $db_lozinka){
echo "Uspesno ste ulogovani";
$_SESSION['ime'] == $ime;
echo $_SESSION['ime'];
}
else { echo "Lozinka je netacna"; }
} else {die("Korisnik ne postoji");}
}
}

?>
What seems to be the problem 

Hello Everyone!

I have 2 problems with sessions that I'd like some assistance with.
1. The session often ends after clicking any link after logging in. (sometimes it remains alive, and in those cases it stays alive until browser is closed.)
2. The function that should start a session if a cookie is found (and correct) is not working, so if the browser is closed and re-opened the session won't start the session.

I'll include the code that I think is relevant. The odd part is that these problems occur in every browser, I have tried multiple tutorials (so different scripts) to creating a login form but somehow the same result appears every time.

function login($username, $password, $remember = false) 
{


    $sql = mysql_query("SELECT * FROM users WHERE password = '" . md5($password) . "' AND username = '" . $username . "' LIMIT 1");
    // If there are no matches then the username and password do not match
    if($sql === false) 
    {
        return false;
    }
    else
    {
        while($u = mysql_fetch_array($sql))
        { 
                
                // Check if user wants account to be saved in cookie
                if($remember == true)
                {
                    // Generate new auth key for each log in (so old auth key can not be used multiple times in case 
                    // of cookie hijacking)
                    $cookie_auth= rand_string(10) . $username;
                    $auth_key = session_encrypt($cookie_auth);
                    $auth_query = mysql_query("UPDATE users SET auth_key = '" . $auth_key . "' WHERE username = '" . $username . "'");
 
                    setcookie("auth_key", $auth_key, time() + 60 * 60 * 24 * 7, "/", "mycorrectwebsite.com", false, true);
                }
                // Assign variables to session
                session_regenerate_id(true);
                $session_id = $u[id];
                $session_username = $username;
                $session_level = $u[user_level];
 
                $_SESSION['user_id'] = $session_id;
                $_SESSION['user_level'] = $session_level;
                $_SESSION['user_name'] = $session_username;
                $_SESSION['user_lastactive'] = time();
return true;
        }
    }
} 

function initiate()
{
$logged_in = false;
if(isset($_SESSION['user_name']))
{
$logged_in = true;
}
 
        // Check that cookie is set
        if(isset($_COOKIE['auth_key']))
        {
            $auth_key = $_COOKIE['auth_key'];
 
            if($logged_in === false)
            {
                // Select user from database where auth key matches (auth keys are unique)
                $auth_key_query = mysql_query("SELECT username, password FROM users WHERE auth_key = '" . $auth_key . "' LIMIT 1");
                if($auth_key_query === false)
                {
                    // If auth key does not belong to a user delete the cookie
                    setcookie("auth_key", "", time() - 3600);
                }
                else
                {
                    while($u = mysql_fetch_array($auth_key_query))
                    {
                        // Go ahead and log in
                        login($u['username'], $u['password'], true);
                    }
                }
            }
            else
            {
                setcookie("auth_key", "", time() - 3600);
            }
        }
 
}


And then in the header I start every page with:


<?php 
session_start();
include("connect.php");
include("functions.php");
include("actions.php");

initiate();
 ?>

I'm using xampp and am trying to create a login session...these are the my php files
login.php
Code: [Select]
<form action='login1.php' method='post'>
Email: <input type='text' name='id'></br>
Pass : <input type='password' name='pass'></br>
<input type='submit' name='login' value='login'>
login1.php
Code: [Select]
<?php
$id=$_POST['id'];
$pass=$_POST['pass'];

$conn=mysql_connect("localhost","root","");
if (!$conn)
{
die('Could not connect: ' . mysql_error());
}


$e=mysql_select_db('test', $conn);
if(!$e)
{
die(''.mysql_error());
}
else
{
echo 'database selected successfully';
}

$sql=mysql_query("Select email,password from login where email='$id' AND password='$pass'");
$count=mysql_num_rows($sql);
if($count==1) 
{ 
    session_start();
    
    echo "</br>Login Successful</br>";
echo "Please wait 5 seconds ";
/* redirct to the specified page */
header("refresh:5;url=empty.php");
}
else
{

echo "please try to login again</br>";
echo "you will be redirected to the login page in 5 seconds";
     /* redirct to the specified page */
header("refresh:5;url=login.php");
}
mysql_close();
?>
empty.php
Code: [Select]
<?php
session_start();

$logi=$_SESSION['id'];
echo 'welcome '.$logi;



?>

empty.php is supposed to display the email id from login.php
I checked it about an hour ago and it was working fine but now it gives me an error
Undefined index: id in C:\xampp\htdocs\littleprogress\empty.php on line 4
I didn't change anything after checking it. only cleared the history and cookies of my firefox browser
what could be the problem

Hi guys.

Im making a script that stores different contents in sessions. And everything seems to be working fine. I previously had some problems with it, but managed to fix them. Now somehow a new problem have accrued for me. I did not do anything to it since it last worked. So i am a little confused. It keeps telling me that the session does not have any content.

I think that the problem is within these two files he

http://pastebin.com/T6sfzjWn

and

http://pastebin.com/BUAuFp6t

It keeps giving me the error on line 24 from the second file.

Can someone please help me and say what i am doing wrong?

I use session code to keep post data. It does not work well .  I have put the program on the web site. This is the link .  http://www.ptiimaging.ca/xx.php   

The program is for the whole web page.

I am having probelm in saving Session variables ALthough I'm writing session_start();
in the header of my php script and saving the values of Session array in the next page. It does not print the values or show right results.

Code: [Select]
session_start();
require_once ("functions.php");

$token=$_GET['t'];
if(!isset($token)){
 
$name = stripslashes($_POST['username']);
$email = stripslashes($_POST['email']);

check_validate_input($name, $email);
}
if($token=='register')
{
show_registration_form();
}
  $my_model = new model();
  $arr_info = $my_model->check_members($name,$email);
 
   if (($arr_info==NULL)&&($token!='register'))
    {   
    echo '<p> Hello Guest</p><br />';
       show_mailing_form();
    }
   
  else if (($arr_info['role']=='user')||($arr_info['role'] == 'admin'))
    {
         $_SESSION['userId']=$arr_info['id'];
         $_SESSION['user_role']=$arr_info['role'];
         $_SESSION['user_name']=$arr_info['name'];
        print_r  ($_SESSION);}
here it does not print session array.

hi i want to include session so that attendance.php can't be acess directly..

which is the best place to put this code :

Code: [Select]
if(isset($_SESSION['last_ip'])===false){
$_SESSION['last_ip']=$_SERVER['REMOTE_ADDR'];
}
if($_SESSION['last_ip']!==$_SERVER['REMOTE_ADDR']){
session_unset();
session_destroy();
}
like this :

Code: [Select]
class session {
public $user_on=false;
public $user_id;

function __construct(){
//make sure that javascript can not access session variable
ini_set('session.cookie_httponly',true);
session_start();
//set the last ip the user has logged on with
if(isset($_SESSION['last_ip'])===false){
$_SESSION['last_ip']=$_SERVER['REMOTE_ADDR'];
}
if($_SESSION['last_ip']!==$_SERVER['REMOTE_ADDR']){
session_unset();
session_destroy();
}
$this->check_login();
}

private function check_login(){
if(isset($_SESSION['user_id'])){
global $user;
$this->user_id=$_SESSION['user_id'];
$this->user_on=true;
$user->find_by_id($this->user_id);
} else {
unset($this->user_id);
$this->user_on=false;
}
}
}
OR :
Code: [Select]
function __construct(){
//make sure that javascript can not access session variable
ini_set('session.cookie_httponly',true);
session_start();
$this->check_login();
}

private function check_login(){
if(isset($_SESSION['user_id'])){
global $user;
                        [b]//set the last ip the user has logged on with
if(isset($_SESSION['last_ip'])===false){
$_SESSION['last_ip']=$_SERVER['REMOTE_ADDR'];
}
if($_SESSION['last_ip']!==$_SERVER['REMOTE_ADDR']){
session_unset();
session_destroy();
}[/b]
                elseif($_SESSION['last_ip']===$_SERVER['REMOTE_ADDR']){
$this->user_id=$_SESSION['user_id'];
$this->user_on=true;
$user->find_by_id($this->user_id);
                 }
} else {
unset($this->user_id);
$this->user_on=false;
}
}
}

Hi,
I my first problem is hashing passwords to md5.
My second problem is defining session on value from db.
There is my code but not working.
Code: [Select]
mysql_connect("$host", "$username", "$password")or die("cannot connect");
mysql_select_db("$db_name")or die("cannot select DB");

 
$username=$_POST['username'];
$password=$_POST['password'];
$hash = md5($password);


$username = stripslashes($username);
$password = stripslashes($password);
$username = mysql_real_escape_string($username);
$password = mysql_real_escape_string($password);

$sql="SELECT * FROM $tbl_name WHERE where username = '$username' and password = '$hash'";
$result=mysql_query($sql);

$count=mysql_num_rows($result);

if($count==1){
$sql2="SELECT access FROM $tbl_name WHERE username='$username' and password='$password'";
$access=mysql_query("$sql2");
session_register("username");
session_register("password");
session_register("access");
$_SESSION["access"]=$access;
header("location:success.php");
}
else {
echo "Invalid Username or Password";Thanks for any answers.

hello all,

I have a client that wants to protect their web page with a password protected landing page. Once the password is entered the user is directed to a "disclaimer" page that they have to agree to first before going into the site. I have put both the landing page and the disclaimer page in my root directory and then the site I put in a sub directory /cms/

in the main site index.php I check for the post password and then set a $_COOKIE for the user that will expire in 1 month
<?php 
// this goes on the very top of the index.php file in the template you are using
//check if user has entered password and needs cookie set
if(isset($_POST['fpass']) && !isset($_COOKIE['fpass'])) setcookielive('fpass', $_POST['fpass'], strtotime( '+1 month' ));


function setcookielive($name, $value='', $expire=0, $path='', $domain='', $secure=false, $httponly=false) {
    //set a cookie as usual, but ALSO add it to $_COOKIE so the current page load has access
    $_COOKIE[$name] = $value;
    return setcookie($name,$value,$expire,$path,$domain,$secure,$httponly);
}

The next thing I do is check if a user is trying to access the main site with having the COOKIE - if so I redirect the user to the landing page
//check if user has not entered password
if (!isset($_COOKIE['fpass']) || $_COOKIE['fpass'] == "") header('location: http://www.mypage.com');

This works fine up to this point.
Now my problem is that I also need to check if a user has the month long cookie set but is trying to access the main page without viewing the disclaimer page first.
I thought this would work:
//check if the user has a cookie set but is on a new session
if (isset($_COOKIE['fpass']) && !isset($_SESSION['fpass'])) header('location: http://www.mypage.com/disclaimer.php');
But this only throws the user into a loop of "disclaimer" -> "landing page" -> "disclaimer" etc. They can never get into the main site.

How do I check for the cookie and whether the user has visited the disclaimer page - but then allow the user to continue once they go to the disclaimer page?

NB: the $_SESSION is not set until the main site.

Hello,

I have the $_session code working, but after I destroy the session and I am asked to log in again, my browser doesn't ask me for my password and just logs me in.

I don't understand because I have destroyed my session and I have deleted the data in $_SESSION and I have deleted the info in the cookie so it shouldn't log me in automatically. I thought it was something in my browser, but I erased my history and I never saved any password.

Here's my code:

This is the welcome page

<?php
    require_once 'login.php';
    $connection = new mysqli($db_hostname, $db_username, $db_password, $db_database);
    
    if ($connection->connect_error) die($connection->connect_error);
    
    if (isset($_SERVER['PHP_AUTH_USER']) && isset($_SERVER['PHP_AUTH_PW']))
    {
        $un_temp = mysql_entities_fix_string($connection, $_SERVER['PHP_AUTH_USER']);
        $pw_temp = mysql_entities_fix_string($connection, $_SERVER['PHP_AUTH_PW']);
        
        $query = "SELECT * FROM users WHERE username='$un_temp'";
        $result = $connection->query($query);
        
        if (!$result) die($connection->error);
        elseif ($result->num_rows)
        {
            $row = $result->fetch_array(MYSQLI_NUM);
            
            $result->close();
            
            $salt1 = "qm&h*";
            $salt2 = "pg!@";
            
            $token = hash('ripemd128', "$salt1$pw_temp$salt2");
            
            if ($token == $row[3])
            {
                session_start();
                $_SESSION['username'] = $un_temp;
                $_SESSION['password'] = $pw_temp;
                $_SESSION['forename'] = $row[0];
                $_SESSION['surname'] = $row[1];
                
                echo "$row[0] $row[1] : Hi $row[0], you are now logged in as '$row[2]'";
                
                die("<p><a href=continue.php>Click here to continue</a></p>");
            }
            else die("Invalid username/password combination");
        }
        else die("Invalid username/password combination");
    }
    else
    {
        header('WWW-Authenticate: Basic realm="Restricted Section"');
        header('HTTP/1.0 401 Unauthorized');
        die("Please enter your username and password");
    }
    $connection->close();
        
    function mysql_entities_fix_string($connection, $string)
    {
        return htmlentities(mysql_fix_string($connection, $string));
    }
        
    function mysql_fix_string($connection, $string)
    {
        if (get_magic_quotes_gpc()) $string = stripslashes($string);
        return $connection->real_escape_string($string);
    }
?>

and this is the other page:

<?php
    session_start();
    
    if(isset($_SESSION['username']))
    {
        $username = $_SESSION['username'];
        $password = $_SESSION['password'];
        $forename = $_SESSION['forename'];
        $surname = $_SESSION['surname'];
        
        destroy_session_and_data();
        
        echo "Welcome back $forename. <br>
            Your full name is $forename $surname.<br>
            Your username is '$username'
            and your password is '$password'.";
    }
    
    else echo "Please <a href='authenticate2.php'>Click here</a> to log in.";
    
    function destroy_session_and_data()
    {
        $_SESSION = array();
        setcookie(session_name(), '', time() - 2592000,'/');
        session_destroy();
    }
?>

 

When I type the website in i first get prompt to enter my password, when I am authenticated the webpage says: You are now logged in click here to continue. When I do I am directed to another page which confirms that I am still logged in. Then I press refresh and the webpage asks me to "Click here to log in". I do, but it doesn't ask me for my password again. Why? My personal info should be destroyed.

Thank you for responding. It's greatly appreciated

 

 

 

Hi Guys,        Here is the code, once logged in using known credentials it should display the content "welcome..." but it doesn't, instead it is showing "you are not authorized..." as if the session['username']); isn't being taken? 

<?php 	
ini_set('display_errors',1); 
 error_reporting(E_ALL);
		

		

include_once 'includes/db_connect.php';
include_once 'includes/functions.php';
 
sec_session_start();
