Using $session

[Jon]

Hello,

Iam just wondering is this would be the right away to go about this.

So I have a order form on my site which will store my order as a $session before transferring away to my payment gateway (WorldPay). I'll be passing the order number from the $session within payment. Once the payment has been processed/cancel/declined the user will be redirected back to a confirmation page which will display the relevant information and if the order is process ill be using the $session data to generate a order (page)

Iam just wondering if that's a ok use of $session?

Cheers

Jon

Hi,

I'm currently implementing similar functionality for my project. $session seems to work as expected. However, I want to ask PW gurus, what are advantages of PW $session compared to regular PHP $_SESSION? It seems they basically do the same things, $session can be used as $session in template files and should be used as $this->session in module files.

Are there any pros for $session except for chaining?

I think yes, some usage examples:

//validate user
$session->isValidSession($userID)

//get the IP address of the current user
$session->getIP()

// login a user
$session->login($name, $pass)

// login a user without requiring a password
$session->forceLogin($user)

// return true or false whether the user authenticated with the supplied password
$session->authenticate(User $user, $pass)

// logout the current user, and clear all session variables
$session->logout()

// redirect this session to another URL
$session->redirect($url)

// get the session history (if enabled)
$session->getHistory()

I also like the getFor() and setFor() functions, which take the pain of namespacing keys away.
