*****************************************************
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">

<head>
<title>Bob's Auto Parts - Order Results</title>

<body>
<h1>Bob's Auto Parts</h1>
<h2>Order Results</h2>
<?
echo "<p>Order processed at ";
echo date("H:i, jS F");
echo "<br>";
echo "<p>Your order is as follows:";
echo "<br>";
echo $_POST["tireqty"]." Tires<br>";
echo $_POST["oilqty"]." Bottles of oil<br>";
echo $_POST["sparkqty"]." Sparks<br>";
***********************************************
Nu wil ik laten zien wat de bestelling kost....en dan gaat het mis..
vervolg, processorder.php
*****************************************************
define("TIREPRICE", 100);
define("OILPRICE", 10);
define("SPARKPRICE", 4);
$totalqty = $_POST["tireqty"] + $_POST["oilqty"] + $_POST["sparkqty"];
$totalamount = $_POST["tireqty"] * TIREPRICE + $_POST["oilqty"] * OILPRICE + $_POST["sparkqty"] * SPARKPRICE;
$totalamount = number_format($totalamount, 2);
echo "<br>\n";
echo "Items ordered: ".$_POST["totalqty"]."<br>\n";
echo "Subtotal: $".$_POST["totalamount"]."<br>\n";
$taxrate = 0.10; // local sales tax is 10%
$totalamount = $totalamount * (1 + $taxrate);
$totalamount = number_format($totalamount, 2);
echo "Total including tax: $".$totalamount."<br>\n";
*******************************************
Ik krijg de volgende error'"s:
********************************************
Notice: Undefined index: totalqty in processorder.php on line 29
Items ordered:
Dat is deze regel:
echo "Items ordered: ".$_POST["totalqty"]."<br>\n";
en......
Notice: Undefined index: totalamount in processorder.php on line 30
Subtotal: $
Total including tax: $3.30
Dat is deze regel:
echo "Subtotal: $".$_POST["totalamount"]."<br>\n";
