Hi all
I’ve been tasked with coding up a basic shopping cart…
here’s the “working” page
http://www.earthinke.co.uk/main_site/wallpaper.php
All seems well, but if you add a product to the cart, it goes in, but you can’t change the quantity at the cart stage? And in trying it loses the selected colour. Also when you add multiple items of the same spec it adds them as separate items rather than combining them together…
Any advice would be appriecated!!
Heres the code:
[php]<?php
SESSION_START();
/////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////
// Section 1 (if user attempts to add something to the cart from the product page)
/////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////
if (isset($_POST[‘pid’]))
{
$pid = $_POST[‘pid’];
if(isset($_POST[‘selectedcol’]))
{
$colour = $_POST[‘selectedcol’];
$wasFound = false;
$i = 0;
// If the cart session variable is not set or cart array is empty
if (!isset($_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,"colour" => $colour));
} else {
// RUN IF THE CART HAS AT LEAST ONE ITEM IN IT
foreach ($_SESSION["cart_array"] as $each_item) {
$i++;
while (list($key, $value) = each($each_item)) {
if ($key == "item_id" && $value == $pid && $key == "colour" && $value == $colour) {
// That item is in cart already so let's adjust its quantity using array_splice()
array_splice($_SESSION["cart_array"], $i-1, 1, array(array("item_id" => $pid, "colour" => $colour, "quantity" => $each_item['quantity'] + 1)));
$wasFound = true;
} // close if condition
} // close while loop
} // close foreach loop
if ($wasFound == false) {
array_push($_SESSION["cart_array"], array("item_id" => $pid, "colour" => $colour, "quantity" => 1));
}
}
}
header("location: cart.php");
exit();
}
?>
