Hi guys, this codes works perfectly to me, except that i would like to add pricetotal in session variable. my problem is pricetotal does not display values when i use print_r.
Heres the output when i use print_r to display session variable:
Array ( [0] => Array ( [item_id] => 15 [quantity] => 56 [pricetotal] => ) )
It should be like this:
Array ( [0] => Array ( [item_id] => 15 [quantity] => 56 [pricetotal] => 5500) )
please help me to fix my problem: thanks
the code use:
<?php
//Section 1 (if user attempts to add something to the cart from the product page)

$pid = $_POST['pid'];

if (!isset($_SESSION["cart_array"]) || count($_SESSION["cart_array"]) < 1) {
// RUN IF THE CART IS EMPTY OR NOT SET
$_SESSION["cart_array"] = array(0 => array("item_id" => $pid, "quantity" => 1,"pricetotal" => $pricetotal));
} else {
// RUN IF THE CART HAS AT LEAST ONE ITEM IN IT
foreach ($_SESSION["cart_array"] as $each_item) {
$i++;
while (list($key, $value) = each($each_item)) {
