form values passing to script problem

thtmal

PHP 5.2.5
IIS 5.1
Win XP pro
Testing a simple script on local IIS server, I have setup PHP exactly as php.net suggested http://us.php.net/manual/en/install.windows.iis.php, using ISAPI module. Running stand alone scripts like <?php phpinfo(); ?> works fine. But, having a little problem using a form to pass values to another script to generate the return values.

HTML Form (accessed by http://localhost/php/1.php )

<form action="domyhomework.php" method="get">
Width: <input type="text" name="w" /><br />
Height: <input type="text" name="h" /><br />
<input type="submit" />
</form>

</body>
</html>

The script that process the form ( Return URL: http://localhost/php/domyhomework.php?w=4&h=5 )

<?php
$area = $w $h;
$perimeter = ($w + $h) 2;
?>
<html>
<body>
<p>Width: <?=$w?><br />
Height: <?=$h?></p>
<p>Area: <?=$area?><br />
Perimeter: <?=$perimeter?></p>
</body>
</head>

Results (no values returned, but when tested on a remote Linux hosting server, it works fine. What am I missing here. Thanks ahead of time)

Width:
Height:

Area:
Perimeter:

Try changing your script code to:

<?php
$w = isset($_GET['w']) ? $_GET['w'] : '';
$h = isset($_GET['h']) ? $_GET['h'] : '';
$area = $w * $h;
$perimeter = ($w + $h) * 2;
?>
<html>
<body>
<p>Width: <?php echo $w; ?><br />
Height: <?php echo $h; ?></p>
<p>Area: <?php echo $area; ?><br />
Perimeter: <?php echo $perimeter; ?></p>
</body>
</head>

This will make it work if your set up has register_globals disabled or short_open_tag disabled.
