PHP - Session Object Not Working?

Hello, I'm trying to test a simple login system without a db, just for testing purposes. I have created a php file that checks if the username and pass are valid and register a session.

Code: [Select]
<?php
session_start();
define("ADMINUSER", "user");
define("ADMINPASSWORD", "pass");
$user = $_POST['user'];
$pass = $_POST['pass'];
if (($user==ADMINUSER) && ($pass==ADMINPASSWORD))
{
    $_SESSION['logged_in'] = true;
    header("Location: main.php");
}
else
{
    header("Location: auth.php?flag=wrong");
}
?>

and include this in other files to check if the user is logged in:

Code: [Select]
<? session_start();
if ($_SESSION['logged_in'] != true)
{
    header("Location: auth.php?flag=not");
    exit;
}
?>

But this doesn't seem to work, as I closed the window, clear my cookies and shutdown my PC and when I try to open it again and it doesn't redirect me to the login page(auth.php).

What am I doing wrong ? Any help is appreciated.

Code: [Select]
$itemlisted = $_POST['itemlisted'];

if ($itemlisted) {
 
unset($_SESSION['items'][$itemlisted]);
 }
 

it should work i don't get it.  $itemlisted is 1... so it should delete [1] in the array.  any idea why it's not working?

As the title says session, post and get are not working. This is what i use to initialize them. For get just switch session with get.

Code: [Select]
foreach ($row as $val)
          { 
            $_SESSION[$rowcount] = $val;
//              echo "<td>$val</td>\n";
                $rowcount=$rowcount+1;
      }
when i was using session i would check to make sure that they were working with a couple of these lines in the same php document.

Code: [Select]
echo "Session row 1 = ".$_SESSION[0]."<br />";
echo "Session row 2 = ".$_SESSION[1]."<br />";
then on the next page where I was trying to receive the variables i was using this just to start off with and make sure i was getting the variables.

Code: [Select]
session_start();
if(!isset($_SESSION[1])){
echo "help1";}else{$var=$_SESSION[1];
}
echo $_SESSION[1];
echo $var;
if i switch to post and get i get the same results. if there is an easier way to pass variables between pages id love to hear them

Hello, for some reason I am unable to get the following code to work:

Code: [Select]
<?php
echo "<h1>Login</h1>";

if ($_SESSION['uid']) {
    echo "&nbsp; &nbsp; You are already logged in, if you wish to log out, please <a href=\"./logout.php\">click here</a>!\n";
} else {

if (!$_POST['submit']) {
echo "<table border=\"0\" cellspacing=\"3\" cellpadding=\"3\">\n";
echo "<form method=\"post\" action=\"./login.php\">\n";
echo "<tr><td>Username</td><td><input type=\"text\" name=\"username\"></td></tr>\n";
echo "<tr><td>Password</td><td><input type=\"password\" name=\"password\"></td></tr>\n";
echo "<tr><td colspan=\"2\" align=\"right\"><input type=\"submit\" name=\"submit\" value=\"Login\"></td></tr>\n";
echo "</form></table>\n";
}else {
$user = addslashes(strip_tags(($_POST['username'])));
$pass = addslashes(strip_tags($_POST['password']));
        
            if($user && $pass){
                $sql = "SELECT id FROM `users` WHERE `username`='".$user."'";
                $res = mysql_query($sql) or die(mysql_error());
                if(mysql_num_rows($res) > 0){
                    $sql2 = "SELECT id FROM `users` WHERE `username`='".$user."' AND `password`='".md5($pass)."'";
                    $res2 = mysql_query($sql2) or die(mysql_error());
                    if(mysql_num_rows($res2) > 0){

$query = mysql_query("SELECT locked FROM `users` WHERE `username`='".$user."'");
$row2 = mysql_fetch_assoc($query);
$locked = $row2['locked'];

$query = mysql_query("SELECT active FROM `users` WHERE `username`='".$user."'");
$row3 = mysql_fetch_assoc($query);
$active = $row3['active'];

$query = mysql_query("SELECT email FROM `users` WHERE `username`='".$user."'");
$row3 = mysql_fetch_assoc($query);
$email = $row3['email'];


if ($active ==1){

if ($locked == 0){

$date = date("j")."^{".date("S")."} ".date("F, Y");

mysql_query("UPDATE users SET last_login='$date' WHERE username='$user'");

$row = mysql_fetch_assoc($res2);
$_SESSION['uid'] = $row['id'];
$previous = $_COOKIE['prev_url'];
echo "&nbsp; &nbsp; You have successfully logged in as " . $user . "<br><br><a href='" . $previous . "'>Click here</a> to go to the previous page.\n";
}else
{
echo "Your acount has been locked out due to a violation of the rules, if you think there has been a mistake please <a href='contact.php'>contact us</a>.";
}
} else {
echo "You need to activate your account! Please check your email ($email)";
}
   }else {
                        echo "&nbsp; &nbsp; Username and password combination are incorrect!\n";
                    }
                }else {
                    echo "&nbsp; &nbsp; The username you supplied does not exist!\n";
                }
            }else {
                echo "&nbsp; &nbsp; You must supply both the username and password field!\n";
            }
}

}
?>
It says that I have logged in successfully but the session is not created. You can find the script here and log in with the username "test" and the password "testing". I'm not sure what more information I should add.

Thanks,
Cameron

Hello guys. I'm in need of help. I want to know who to make a full working session.


When a player logs in, the session starts. There will be a new button "My Page", he can go there at any time. When he logs off, that button disappears ( Session over ). I'm so bad at explaining stuff. Hope y'all really understood me.

This piece of code is used to log the user in:
Code: [Select]
<?php
session_start();
include("config.php");
if(isset($_SESSION["Username"]))
{
$user = $_SESSION["Username"];
$pass = md5($_SESSION["Password"]);
}
else
{
$user = $_POST["User"];
$pass = md5($_POST["Password"]);
$_SESSION['Username'] = $user;
$_SESSION['Password'] = $pass;

$escuser = mysql_real_escape_string($user);
$escpass = mysql_real_escape_string($pass);
}

$result = mysql_query("SELECT * FROM playerinfo WHERE user = '$escuser'");
$num_rows = mysql_num_rows($result);
if($num_rows == 0)
{
echo('That username does not exist...');
echo '<a href="http://yu-ki-ko.com/fsns/"">  Go back!</a>';
unset($_SESSION['Username']);
unset($_SESSION['Password']);
die;
}

$row = mysql_fetch_row($result);
if($row[1] !== $escpass)
{
echo('Wrong Password!...');
echo '<a href="http://yu-ki-ko.com/fsns/"">  Go Back!</a>';
unset($_SESSION['Username']);
unset($_SESSION['Password']);
die;
}
?>

Not sure if its working properly or not. I'm stuck at that part.

Hi everyone,

I am trying to implement an OAuth system in PHP. I've got the code working but the very first time a fresh, new browser window is opened, the code doesn't work. If I refresh the page and try again, then it works. I have a few suspicions as to where the problem might be but other than that I am stumped.

I have two classes: OAuthServer and OAuthClient. I create and store an object of the appropriate class in session variables. I know this is tricky but I am serializing and unserializing properly. To fetch responses from the Server, I am using curl. As curl uses a different session from the browser, I am doing a session_write_close before initializing curl and passing the appropriate parameters to curl.

But my code needed to further write session variables even after session_write_close was called and to achieve this, I am calling session_start(), once again, after the curl code is finished. I found that this works but PHP was throwing warnings saying that the header info had already been sent or something like that, but I have suppressed such warnings. I suspect the error has something to do with this but I'm not sure.

The part that doesn't work the very first time is that on the server-side, the session variable that is supposed to contain the OAuthServer object is NULL. But if I do a refresh of the page(flow: login_page->error_page), it works.

Can anyone tell me why I am encountering the above error and if I am doing things correctly or not. Any help would be greatly appreciated.

Thanks & Regards,

hi guys.
i am trying to set a variable to the session global variable. I've initialized the session with session_start();  at the very beginning of my website, and then i try finding if a session variable has been set like so if(isset($_SESSION['user'])) { print 'user is logged in'; } but this works in reverse.  i have not set any session variables, but asking if it is set, results in an affirmative answer.

so i am thinking this is because of register_globals. because i went to read about register_globals, and it says that if register_globals is turned off, i cannot use any other varibale except members of the session array. i dont know what that is yet, but a question befo in the php manual it says register_globals is deprecated, and it appears i need to enable it to set other variables as session variables besides it's associative array. if this is true, how to enable register_globals and allow other variables to be used as session variables?

Hello everyone.

Any help or suggestion would be appreciated

i have this problem
Code: [Select]
Warning: session_start() [function.session-start]: Cannot send session cache limiter - headers already sent (output started at /home/maximasy/public_html/newscp/index.php:1) in /home/maximasy/public_html/newscp/index.php on line 2

my source code is

<?php
session_start();
include_once("config.php"); 
include_once("functions.php");
$errorMessage = '';
if (isset($_POST['txtUserId']) && isset($_POST['txtPassword'])) {
if ($_POST['txtUserId'] === "$user" && $_POST['txtPassword'] === "$pass") {
// the user id and password match,
$_SESSION['basic_is_logged_in'] = true;
require("main.php");
exit;?>

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!

Hello everyone,

I can get Test 2 to successfully operate the if statement using a variable variable.

But when I try the same method using a session variable (Test 1) the if statement is not executed. Please could you tell me why the if statement in Test 1 is not being executed?

Code: [Select]

<?php
# TEST 1
$_SESSION[test_variable] = "abcd";
$session_variable_name = "_SESSION[test_variable]";
if ($$session_variable_name == "abcd")
{
echo "<br>line 373, abcd<br>";
}

# TEST 2
$test_variable = "efgh";
$test_variable_name = "test_variable";
if ($$test_variable_name == "efgh")
{
echo "<br>line 379, efgh<br>";
}

?>
Many thanks,

Hey all,

I want to have an object that has a property which is an object containing instances of other objects. I try this:
Code: [Select]
class Blog extends Posts {
public $has_posts;

public function __construct($a,$b,$c){
$has_posts = (object) array_merge((array) $a, (array) $b, (array) $c);
}
}

class Posts {
public $b;

public function __construct($b){
$this->b = $b;
}
}

$post1 = new Posts(1);
$post2 = new Posts(2);
$post3 = new Posts(3);

$blog = new Blog($post1,$post2,$post3);
var_dump($blog->has_posts); //null
foreach($blog->has_posts as $post){ //Invalid argument supplied for foreach()
echo $post->b;
}

But as you see, has_posts is null, not an object containing other objects.

Thanks for response.

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>
