Newbie Post Method Problems

easygoingfellow

Hi Y'all, Having a problem with post, which is driving me nuts. Basically I'm following an example out of a PHP book "PHP and MySQL Web Development" and the variables are not being passed from an HTML form to the PHP file. The HTML form is at: http://www.ensley.ca/harold/phptest/orderform.html

And the PHP file is as follows:
<html>
<head>
<title>Bob's Auto Parts - Order Results</title>
</head>
<body>
<h1>Bob's Auto Parts</h1>
<h2>Order Results</h2>
<?
echo "<p>Order processed at "; // Start printing order

echo date("H:i, jS F");
echo "<br>";
echo "<p>Your order is as follows:";
echo "<br>";
echo $tyreqty." tyres<br>";
echo $oilqty." bottles of oil<br>";
echo $sparkqty." spark plugs<br>";

$totalqty = 0;
$totalamount = 0.00;

define("TYREPRICE", 100);
define("OILPRICE", 10);
define("SPARKPRICE", 4);

$totalqty = $tyreqty + $oilqty + $sparkqty;
$totalamount = $tyreqty TYREPRICE
+ $oilqty OILPRICE
+ $sparkqty * SPARKPRICE;

echo "<br>\n";
echo "Items ordered: ".$totalqty."<br>\n";
echo "Subtotal: $";
echo number_format($totalamount, 2);
echo "<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";

?>
</body>
</html>

Not sure why this won't work. If anyone has any ideas, let me know. Thanks!

I am betting that register_globals is turned off on your server. You can do a couple of things

1) instead of saying $varname say $POST['varname'] or $GET['varname'] as appropriate.

2) use this function - it's a php implementation of register_globals on that pulls the form variables in for you even if register globals is off and does not conflict if they are on:

<?php
function reg_globals() {
    foreach($_GET as $curVar) {
        global $$curVar;
        $$curVar = $_GET[$curVar];
    } //end foreach
    foreach($_POST as $curVar) {
        global $$curVar;
        $$curVar = $_POST[$curVar];
    } //end foreach
} //end reg_globals
?>

if you use this just make sure you call reg_globals before you use any code that references them.

Would you recommend turing on register_global in the ini file?

The first solution works really well. I'm still trying to figure out the second solution-- I'm sure this is the superior solution-- since I'm not yet a real programmer.

If it's not too much bother, can someone show me how to use drawmuck's function (called from a second fle) into the PHP file I've included below. Thanks.
