Forms submitting to a session array

I'm trying to create a shopping cart where users can visit a product pag=
e =

(called from a MySQL database depending on the url ending in =

?product_id=3D#). On the product page users can select options from drop=
down =

lists (such as color, etc.) These dropdown lists are also dynamically =

generated from the database.

I need to store what the user has selected while the user browses the =

site. I want to also display what they've selected on a "cart" page.

I believe my best option is to store what they've selected in a session =
=

array. I'm not sure how to do this with the dropdown lists, etc.

Any help would be greatly appreciated!

In exactly the same way as any other data. If you want to save it
per-product, you could do something like this.

session_start();

if (empty($_SESSION['products'])) {
$_SESSION['products'] = array();
}

// appropriate checking for form submission here.
// and also making sure proper colors or whatever are posted.
// ....

$session_product = array();
$session_product['product_id'] = $_POST['product_id'];
$session_product['color'] = $_POST['color'];

// add the new array of info to the session.
array_push($_SESSION['products'], $session_product);


now if you print_r($_SESSION['products']) you'll see a big array of info
with each product having a color.
