Probably easiest to explain what I am trying to do, to illustrate the impasse I have came to. I have online store with a number of products. Visitors can click on products, clicking brings details of the product came up in a iframe on the right (with a field to enter the quantity), which can than be added to the shopping cart in a separate iframe below it bottom right by click add product (passed using a different script (the one which I am having issues with)). So each time a product is added to the cart, three dynamic hidden fields are passed via post, which are named "product_name", "unit_quantity" and "unit_price".
So for the shopping cart, I want to incorporate an associative array using the three dynamic fields described above("product_name", "unit_quantity" and "unit_price") within a session so that a number of products can be added (hence using an array rather than a variable).
So shopping cart i have done so far reads:
<?php
session_start();
if (!isset ($product_name) && !empty($product_name))
{
if (!session_is_registered("product_info"))
{
$pos=0;
session_register("pos");
$product_info[$pos]= array ( 'product_name'=>$product_name, 'unit_quantity'=>$unit_quantity,
'product_quantity'=>$unit_quantity * $unit_price);
session_register("product_info");
}
?>
Not sure (as I am new to sessions, how to call the array to the screen). I have read through past threads but have not been able to found anything similar to what I am trying to achieve).
Any hints?

Re: Dynamic Associative Arrays and Sessions
1.) the preferred and more reliable way to register a session is to use $_SESSION instead of session_register....eg.
and depending on what part of the array that you wanted to see you could use...
which would show you the entire array,or you could pick out something specific by using array_keys(), array_values(), array_search()...something like that
Code: Select all
$_SESSION["pos"] = 0;Code: Select all
print_r($product_info[$pos]);
