Hello all,
I've made a simple shopping site and ran into a problem.
When a user adds a item to his cart, the same page should appear. But now, the frontpage appears. In other words, i want him to return to the same page from where he added that item to the cart.

can anyone help???

    You probably need a script that points to itself and also passes on variables to itself. So the visitor would never actually leave the page, only what he sees would change. But that is just an initial implement. You'd need sessions and cookies for that kind of project.

Uhm... why cookies and sessions?

When you go to the cart, store the $HTTP_REFERER value.
When the cart is finished, use a header('Location: bladebla') to send the user back to the original $HTTP_REFERER value.

Simple as that.

    Sessions was just a guess, I still haven't written that chapter of the book ;-) Now, sometimes you click a link and the page fails to load. Frankly, I have no idea if the original $HTTP_REFERER value is kept or lost in that case. What if the computer crashes? Cookies can let the visitor resume from where they left off. Think of a supermarket, for example. You have 30 items in your cart, you don't want to lose them and have to select everything again. What if someone recommends a product to a friend and that friend makes a direct hit? Sure, you can sport a presentation page and an order page, but you must be ready to handle direct hits in the order page at any rate. Oh, well, I'm a newbie in PHP and a newbie in programming altogether, so pardon me if I am blurting out nonsense. If I had to make an online store, I would use a database behind a single-script-based site. That is what I felt like telling kiddie in the first place, that is what I meant with "a script that points to itself", but it sounded lame, so I suggested cookies. But if you say it can all be just that simple, maybe my idea was not so lame after all.

    Nice chatting,

I have all the functions in the same page. So, I need a script that'll load the same page as the one which refers it(i.e. to be directed where the user added that item from)
Thanks in advance

    Is that a question?
