I have just installed WAMPServer 2.0, and it got me most of the way to success!
I have a short PHP script I am using as a training aid. Here is the HTML that calls the script:
<form action="[localhost]; method="post">
<table border="0">
<tr bgcolor="#cccccc">
<td width="150">Item</td>
<td width="15">Quantity</td>
</tr>
<tr>
<td>Tires</td>
<td align="center"><input type="text" name="tireqty" size="3" maxlength="3" >
</tr>
<tr>
<td>Oil</td>
<td align="center"><input type="text" name="oilqty" size="3" maxlength="3" >
</tr>
<tr>
<td>Spark Plugs
</td>
<td align="center"><input type="text" name="sparkqty" size="3" maxlength="3">
</tr>
<tr>
<td colspan="2" align="center"><input type="submit" value="Submit Order"
</td>
</tr>
</table>
</form>
And the PHP script it calls in Processorder.php is:
<html>
<head>
<title>Bob's Auto Parts-Order Results</title>
</head>
<body>
<h1>Bob's Auto Parts</h1>
<h2>Order Results</h2>
<?php
echo '<p>Order Processed.</p>';
$totalqty = 0;
$totalqty = $tireqty + $oilqty + $sparkqty;
echo "Items ordered: " , $totalqty , "<br>" ;
define('TIREPRICE', 79.95);
define('OILPRICE', 5.98);
define('SPARKPRICE', 4.95);
$tireprice = ($tireqty * TIREPRICE);
$oilprice = ($oilqty * OILPRICE) ;
$sparkprice = ($sparkqty * SPARKPRICE);
$taxrate = 0.06; //Sales tax is 6%
$totalbill=0.00;
$tirebill=0.00;
$tirebill=$tireqty*$tireprice;
echo "Tires: " , $tireqty , " at $" , $tireprice , " = $" , number_format($tirebill,2) , "<br>";
$oilbill=$oilqty*$oilprice;
echo "Quarts of Oil: " , $oilqty , " at $" , $oilprice , " = $" , number_format($oilbill,2) , "<br>";
$sparkbill=$sparkqty*$sparkprice;
echo "Spark Plugs: " , $sparkqty , " at $" , $sparkprice , " = $" , number_format($sparkbill,2) , "<br>";
$totalbill=($tirebill+$oilbill+$sparkbill);
echo "Total Taxable = $" , number_format($totalbill,2) , "<br>";
$totalbill*=(1+$taxrate);
echo "Total with Tax = $" , number_format($totalbill,2) , "<br>";
?>
</body>
</html>
On a Website I maintain as a volunteer, this same script, the only difference being that rather than "localhost" I call Processorder.php using the address provided by the web host, all works fine: I fill in the form, and click Submit Order, and the information is calculated and echoed to the screen.
On my computer with WAMP, the PHP script is called, but none of the data I enter is posted.
The output looks like this:
Bob's Auto Parts
Order Results
Order Processed.
Notice: Undefined variable: oilqty in C:\wamp\www\Processorder.php on line 11
Notice: Undefined variable: tireqty in C:\wamp\www\Processorder.php on line 11
Notice: Undefined variable: sparkqty in C:\wamp\www\Processorder.php on line 11
Items ordered: 0
Notice: Undefined variable: tireqty in C:\wamp\www\Processorder.php on line 18
Notice: Undefined variable: oilqty in C:\wamp\www\Processorder.php on line 19
Notice: Undefined variable: sparkqty in C:\wamp\www\Processorder.php on line 20
Notice: Undefined variable: tireqty in C:\wamp\www\Processorder.php on line 28
Tires:
Notice: Undefined variable: tireqty in C:\wamp\www\Processorder.php on line 29
at $0 = $0.00
Notice: Undefined variable: oilqty in C:\wamp\www\Processorder.php on line 30
Quarts of Oil:
Notice: Undefined variable: oilqty in C:\wamp\www\Processorder.php on line 31
at $0 = $0.00
Notice: Undefined variable: sparkqty in C:\wamp\www\Processorder.php on line 32
Spark Plugs:
Notice: Undefined variable: sparkqty in C:\wamp\www\Processorder.php on line 33
at $0 = $0.00
Total Taxable = $0.00
Total with Tax = $0.00
I am greatly encouraged by the fact that the PHP script is found and executed. Even seeing the Error Codes beat seeing a File Not Found error, or some indication that the PHP code was not run at all (my previous best result).
I strongly suspect what I have here is a problem in php.ini or something else in WAMP which is simply failing to record and post the data to Processorder.php.
Any ideas? What should I do next?
Thanks!

weve seen this a couple of times. it from a really old book
first the script is wrong for new php
its missing some lines at the start of the php file
$tireqty = $_POST['tireqty'];
$oilqty = $_POST['oilqty'];
$sparkqty = $_POST['sparkqty'];
you need to actually take them for the $_POST array in new php
secondly some of those erros are only notices cos the files not written brilliantly. first make the change i said. if you still have errors ill explain how to get rid
