I've been trying for ages to add a form field qty to an array to pass it to
my shopping cart and have finally managed it but not quite.
Please check this cart:
http://www.violasystems.com/shop_testing/
When you add an item using the form text box it doesn't add more than 1 on
the first submit. However if you go back and then add further items it's
will add the multiple products to the cart? I have three functions which
control this and can't see where I'm going wrong:
Submitting the form:
echo " ";
echo "";
echo "Quantity required: ";
echo "";
echo "";
echo "";
echo "";
echo " ";
Processing the form:
$qty)
{
if($$ItemCode=="0")
unset($cart[$ItemCode]);
else
$cart[$ItemCode] = $$ItemCode;
}
$total_price = calculate_price($cart);
$items = calculate_items($cart);
}
do_html_header("Your shopping cart");
//array de-bug
//print_r($cart);
if($cart&&array_count_values($cart))
display_cart($cart);
else
{
echo " There are
no items in your cart";
echo "";
}
$target = "index.php";
// if we have just added an item to the cart, continue shopping in that
category
if($new)
{
$details = get_product_details($new);
if($details["catid"])
$target = "show_cat.php?catid=".$details["catid"];
}
$path = $PHP_SELF;
$path = str_replace("show_cart.php", "", $path);
echo " ";
display_button($target, "continue-shopping", "Continue Shopping");
display_button("http://".$SERVER_NAME.$path."checkout.php";,
"go-to-checkout", "Go To Checkout");
echo "";
do_html_footer();
?>
And displaying the cart:
function display_cart($cart, $change = true, $images = 1)
{
// display items in shopping cart
// optionally allow changes (true or false)
// optionally include images (1 - yes, 0 - no)
global $items;
global $total_price;
echo "
Item
PriceQuantity
Total";
//display each item as a table row
$qty = $formqty;
foreach ($cart as $ItemCode => $qty)
{
$product = get_product_details($ItemCode);
echo " ";
if($images ==true)
{
echo "";
if (file_exists("images/$ItemCode.jpg"))
{
$size = GetImageSize("images/".$ItemCode.".jpg");
if($size[0]>0 && $size[1]>0)
{
echo "";
}
}
else
echo " ";
echo "";
}
echo "";
echo "".$product["ItemName"]."
(Code) ".$product["ItemCode"];
echo " ".number_format($product["price"], 2);
echo "";
// if we allow changes, quantities are in text boxes
if ($change == true)
echo "";
else
echo $qty;
echo "
".number_format($product["price"]*$qty,2)."\n";
}
// display total row
echo "
$items
".number_format($total_price, 2).
"
";
// display save change button
if($change == true)
{
echo "
";
}
echo "";
}
Any help much appreciated.
