Multiple sessions

sehummel

How do I handle multiple sessions? Do I use session names? Do I create a session ID and start the session with the session name only if the ID is posted? And then destroy all other sessions?

Help, I've never worked with multiple sessions! Also, what is the syntax for the array of item is the session? Would it be something like $_SESSION['cart']['item1']?

Thanks for your help. Also, how do I resolve yesterday's post? I can't find how to track it down.

Could you provide me a sample of the code you suggest for above?

What do you mean by "multiple sessions" ?

Not sure that I understand what you're asking, but you can treat variables in the $SESSION array like you would any other variable.

On the website, there are various different items that the user can configure. The data is stored in the session. If the user stops configuring the item before submitting it and starts configuring the new item, the configuration from the old item will still be stored in the session, right?

So I was wondering if I could get around this problem by having named sessions and destroying all sessions but the current one. How do I do this?

In other words, if the user is configuring item1 and the data is stored in the item1 session, and then the user stopped configuring item1 and started configuring item2, would I destroy the item1 session and starting the item2 session? Hope that is clearer. How do I do this programatically?

That would depend upon how your application uses/stores data in the session.

In that example, just store information identifying which "item" the user is configuring, e.g. $SESSION['item'][1] is an array of info as is $SESSION['item'][2].

If you wanted to delete the temporary data associated with any item other than what they're currently editing, then search through the $_SESSION['item'] array and if the key doesn't match the current item number, [man]unset/man that array item.
