I recently aquired a copy of the book PHP and Mysql web development by SAMS.
I have begun reading through it and it seems to be a very usefull book
however I started doing the first exersise which is a simple HTML Processor,
the HTML page is as follows:
<html>
<head>
<title>Bob's Auto Parts - Order Results</title>
</head>
<body>
<h1>Bob's Auto Parts</h1>
<form action=processorder.php 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></td>
</tr>
<tr>
<td>Oil</td>
<td align=center><input type="text" name="oilqty" size=3 maxlength=3></td>
</tr>
<tr>
<td>Spark Plugs</td>
<td align=center><input type="text" name="sparkqty" size=3 maxlength=3></td>
</tr>
<tr>
<td colspan=2 align=center><input type=submit value="Submit Order"></td>
</tr>
</table>
</form>
</body>
</html>
And the processor PHP page is:
<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 ";
echo date("H:i, ");
echo "on ";
echo date ("jS F");
echo "<br>";
echo "<p>Your order is as follows:";
echo "<br>";
echo $tireqty." tires<br>";
echo $oilqty." bottles of oil<br>";
echo $sparkqty." spark plugs<br>";
?>
</body>
</html>
I get an error???? this code is taken directly from the book.....
