Hi,

are you sure you did not forget a include of the Article source code ?
You need all sources codes aiavlable (included) when getting the object back 
from the session.

Subject: [PHP] Storing objects in sessions recursively
 
PHP List,

I have a class called "Session", which creates an object stored in the 
$_SESSION variable. That object in turn holds on to a "User" object 
which keeps track of the activity of the individual user who has logged 
in and is using the web site. Then the $user object in turn holds on to 
an "Article" object, which keeps information about web content that the 
user is editing, previewing, and viewing.

The problem is that the "article" object keeps getting lost as the user 
clicks from page to page.

I'm hoping someone can explain to me why this might be happening.

As far as I can understand it, an object is basically just an array, and 
an object that "owns" an object as a member variable is just like 
storing an array in an array. I can't see any reason why there would be 
any limit to how many levels one could go down.

So I'm assuming there's no restriction on how many levels of objects 
owning objects there can be.

As for the code itself, I hope I don't strip out any key details, as 
it's all spread out across many classes. But here's what the basics of 
it look like:

In the User class, I have this method:

public function setCurrentArticle($currentArticle)
{
$this->currentArticle = $currentArticle;
}

In the Article class I have this line:

Session::getSession()->getUser()->setCurrentArticle($this);

In the Session class I have:

private static $session;
private $user;

public function __construct()
{
$this->user = new User();
}

public function getUser()
{
return $this->user;
}

public static function getSession()
{
if (!isset($_SESSION['session']))
{
$_SESSION['session'] = new Session();
}
return $_SESSION['session'];
}

I may have missed a detail in trying to keep this brief and readable. If 
so, please let me know and I will try to provide it.

Thank you for any advice.
