Hello everyone
I have coded a php cart for my website. I coded one myself instead of using a big box because it is a membership based sites where users use credits to order not cash.
I have a 'Sizes' table with (size_id and size_name) and a 'Sizes_List' table with (size_id and product_id) which stores the size options of each product. It is displayed fine on the product page.
Anyhoo. It works great.. there aren't any actual errors in the code but I am having trouble with 3 things..
1. displaying the product size [i grab it in $_POST and add it to the cart_array) but it doesn't show up.
2. If I add another product, but a different size, to the cart it just changes the quantity of the product but doesn't add a new line.
3. I need to put items on "hold" for a certain amount of time (e.g. if you add a pair of True Religions in size 32 to your cart they are no longer available to anybody for 20 minutes and if you don't checkout they are back in the store).
For the purpose of this question I have removed the need to be logged in for 1 product page and the cart.
http://www.theskinnyminnie.com/user/rent/product.php?id=4/ <<product
http://www.theskinnyminnie.com/user/mybox.php <<cart
Here is the code it POST the values to the cart (if user adds to cart)
<div id="addproduct"><form id="form1" name="form1" method="post" action="../mybox.php">
<div id ="size">Size:
<select name="size">
<?php echo $the_sizes;?>
</select></div>
<input type="hidden" name="pid" id="pid" value="<?php echo $id; ?>" />
<input type="submit" name="button" id="button" value="Add to Box" />
</form></div>
Here is the code for the cart
User adds to cart:
<?php
/////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////

$asizeid = $_POST['size'];
echo $asizeid;
$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, "asize_id" => $asizeid));
} else {

$i++;
while (list($key, $value) = each($each_item)) {
