PHP - Issue Using Session With Objects

I have a page in which the print_r ($session) displays the following:

What I need to do is loop through the navigationHistory Object , grab the product id, and then get the cPath for that particular product id.  I have worked with sessions a lot, but I cannot seem to ever get the session object and loop thing down.  At this point I am ripping out my hair trying to figure out what is most likely a simple solution to this - can anyone help me?

Hello all!   I have this array of objects:

Array
(
    [0] => stdClass Object
        (
            [first_name] => test
            [last_name] => test
            [title] => test
            [id] => 34
            [type] => 4
            [manager] => 4
            [email] => p@yahoo.com
            [date] => 2014-09-21 07:23:12
            [status] => 2
            [approval_date] => 2014-09-21 07:31:10
            [assessment_id] => 1
            [supervisor_approval] => 1
            [manager_approval_date] => 2014-09-21 07:31:27
            [mainmanger] => 3
        )

    [1] => stdClass Object
        (
            [first_name] => test
            [last_name] => test
            [title] => test
            [id] => 34
            [type] => 4
            [manager] => 4
            [email] => p@yahoo.com
            [date] => 2014-09-20 07:39:55
            [status] => 2
            [approval_date] => 2014-09-20 07:40:41
            [assessment_id] => 3
            [supervisor_approval] => 1
            [manager_approval_date] => 2014-09-20 07:41:07
            [mainmanger] => 3
        )

    [2] => stdClass Object
        (
            [first_name] => jimmy john john
            [last_name] => john
            [title] => Lorad and Master
            [id] => 32
            [type] => 4
            [manager] => 3
            [email] => j@j.com
            [date] => 2014-09-21 07:38:50
            [status] => 2
            [approval_date] => 2014-09-19 07:39:25
            [assessment_id] => 2
            [supervisor_approval] => 1
            [manager_approval_date] => 2014-09-19 07:39:25
            [mainmanger] => 0
        )

)

Where "id" = the user ID.    If there are two or more entries for a user, I want to remove all but the most recent by the "approval_date",... So for the above example it would return:

Array
(
    [0] => stdClass Object
        (
            [first_name] => test
            [last_name] => test
            [title] => test
            [id] => 34
            [type] => 4
            [manager] => 4
            [email] => piznac@yahoo.com
            [date] => 2014-09-21 07:23:12
            [status] => 2
            [approval_date] => 2014-09-21 07:31:10
            [assessment_id] => 1
            [supervisor_approval] => 1
            [manager_approval_date] => 2014-09-21 07:31:27
            [mainmanger] => 3
        )

    [1] => stdClass Object
        (
            [first_name] => jimmy john john
            [last_name] => john
            [title] => Lorad and Master
            [id] => 32
            [type] => 4
            [manager] => 3
            [email] => j@j.com
            [date] => 2014-09-21 07:38:50
            [status] => 2
            [approval_date] => 2014-09-19 07:39:25
            [assessment_id] => 2
            [supervisor_approval] => 1
            [manager_approval_date] => 2014-09-19 07:39:25
            [mainmanger] => 0
        )

)

I'm having a hard time wrapping my head around this concept, so I don't have any example code. And I don't really need or expect someone to code this for me,. just a push in the right direction would be awesome.

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'?

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));
}

function gc($max)
{
$old = time() - $max;

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

function __destruct()
{
session_write_close();
}
}

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.
