Sessions through site

thefisherman

Hello,

I am building an e-commerce site.

Users can go through the site, selecting items which they would like to buy. Those items are added to a cart (database) Well, it works, if 1 person is going through the site.

What i am trying to say is this:
If several users are going through the site, i probably need sessions to keep track of them.
The problem is: I have no idea how to implement this.

How do sessions work, how do i know which user is adding what to which cart?
I am using a database with items to display, and a database which holds the items the user has selected.

Help?

Sessions are the same as variables in every way except they are persistant throughout a visitors session (visit)

You do not need to worry about much, just define the session and whatever page / script the vistor visits the correct values will be held in the variable (as log as you use session_register(var) at the top of each script.

you do not need to worry about seperate sessions in the same way you would not worry about duplicated variables between users.

Ok,

So for instance i have a store, i would start a session when a user enters the site, register a variable that, in some way is linked to the user, and carry it around my site, linking it to the database and do this for everyone, so that in the end the script will now which items belong to which user. (on checkout)

But now for the technical part....

Can you help me with this? I mean, could you give me an example how to do what i wrote above?

Thanks in advance.
