You're not using the $totalqty variable in any of the statements that
modify the $totalamount.

| Hi everyone. Why does my code work when I enter just 1 for

|of 2 or more?
|
|
|
| $totalqty = 0.00;
| $totalamount = 0.00;
|
| define("HALLTABLE", 800);
|
| $totalqty = $_POST["hallqty"]; //quantity
|
| $totalamount = $_POST["hallqty"] * HALLTABLE; //total cost
|
| $totalamount = number_format($totalamount, 2);
| echo $totalamount;
| echo "<br>\n";
| echo "Items ordered: ".$totalqty."<br>\n";
| echo "Subtotal: $".$totalamount."<br>\n";
|
| $taxrate = 0.10; // local sales tax is %10
| $totalamount = $totalamount * (1 + $taxrate);
|
| $totalamount = number_format($totalamount, 2);
|
|
| echo "<br>\n";
| echo "Total including tax: $".$totalamount."<br>\n";

If you remove the first call to number_format(), it works.

because number_format() returns strings and when you do
$totalamount = number_format($totalamount, 2);
you are converting $totalamount to string whose behaviour is uncertain in
subsequent arithmetic operations.
This works:
<?php
$totalqty = 0.00;
$totalamount = 0.00;
define("HALLTABLE", 800);
$totalqty = $_GET["hallqty"]; //quantity
$totalamount = $_GET["hallqty"] * HALLTABLE; //total cost
// $totalamount = number_format($totalamount, 2);
echo number_format($totalamount, 2);
echo "<br>\n";
echo "Items ordered: ".$totalqty."<br>\n";
echo "Subtotal: $".$totalamount."<br>\n";
$taxrate = 0.10; // local sales tax is %10
$totalamount = $totalamount * (1 + $taxrate);
$totalamount = number_format($totalamount, 2);
echo "<br>\n";
echo "Total including tax: $".$totalamount."<br>\n";
?>

Dear Matt,
I noticed on php-windows that you seemed to have some trouble getting
the php_mhash.dll to work for you. Personally I can confirm that this
module works just fine on my dev machine (running win98, PHP 4.3.0,
Apache_1.3.27/mod_ssl & Apache_2.0.44/mod_ssl). So you probably need to
do some extra tweaking to get mhash support up and running.
You already checked php.ini for the correct extensions_dir entry, but
mhash also requires another file to be present and reachable on your
machine: libmhash.dll ! Assuming you use the 'official' windows php
binaries from www.php.net, you'll find this file in the PHP_ROOT/dlls
folder. You could copy libmhash.dll to your PHP_ROOT/extensions dir and
give it a try. Personally I like to retain the official tree layout
(however confusing) and I've added my PHP_ROOT (c:\php) and my
PHP_ROOT/dlls (c:\php\dlls) to the system path. Works like a charm...
If you need any further assistance, don't hesitate to contact me...
Greetings from Belgium,

ok cold fusion has the ability to do a <cfparam name='' default=''>
this lets you specify a variable name to be defaulted to a value if it is
called without being defined. I usually use this for variables specified by
forms either by GET or POST. now I can't find it's equivalent in PHP.. can
anyone direct me in the correct direction?

You could do
if(!isset($var)) $var = 'asdf';
Or if you're using a function, you can specify default values in the
parameter list:
function my_func($var1 = 'default1', $var2 = 'default2') {
// do stuff
// do stuff
}
