Get a unique identifier for the current session?

[Robin S]

I was looking at the API docs for $session and couldn't see any way to get a unique identifier for the current session. I want to use this to create a name for a temp directory so that paths for files stored there for each visitor do not clash with each other.

I can use PHP's session_id() function but I'm surprised there's no ProcessWire $session method for this. Does anyone know if there is a PW way to get an identifier for the current session that I'm missing?

Can't you use one of these?

$_COOKIE["wires"];
$_COOKIE["wires_challenge"];

Seems like the first one is always created, and the second one only if logged in.

ProcessWire uses session_id() internally as well (in SessionHandlerDB), so by all means use that.

I've never had any reason to actually work with session ID's in ProcessWire or heard anyone else asking for this, so my guess is that it's not a very common need, and as such Ryan hasn't felt the need to include a custom getter method for it in the Session class ?

Thanks for the replies. It's no problem to me to use the built-in PHP functions - just wanted to check I wasn't overlooking something.

@Teppo: How would you do a shopping cart if not with the session_id?

@cpx3 You store the products in the session or a cookie, you don't need the session_id to do that.

I set one myself, like so (from within a module):

$this->wire('session')->set('cart', $cart);

A million thanks, that is indeed much easier!
