i've just started to learn php. I installed apache, php and mySQL so they work offline.

I've been teaching myself from this book. Problem is, i've copied a tutorial from the book, word for word, and its not giving the same response thats in the book.

I know apache, and mysql work fine. PHP works also, as the date and time are displayed dynamically, yet the other values aren't.

Can someone have a try on their computer and tell me if i've configured php wrong or if theres an error in my code.

ta ;)

Heres the html page:
<html>
<head>
</head>
<body>
<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>Tyres</td>
<td align =center><input type="text" name="TyreQty" 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 heres the php file:

<html>
<head>
<title> Your Order</title>
</head>
<body>
<h1>Maxwells Motor Parts</h1>
<h2>Your Order Inventory:</h2>
<?
echo "<p>Order processed at " ;
echo date("H:i, jS F");
echo "<br>";
echo "Your order is as follows" ;
echo "<br>";
echo $TyreQty. " tyres<br>";
echo $OilQty. " cans of oil<br>";
echo $SparkQty. " spark plugs<br>";
</body>
</html>

K, I ran it, and first I got

Parse error: parse error, unexpected '<' in C:\Documents and Settings\Jacob Ward\My Documents\Web Pages\Help\processorder.php on line 17.
That was because the PHP block wasn't ended before the HTML block started. So I fixed that,
Next, it said the variables were undefined. This was because my server at least doesn't like using post and get variables without defining them. So I fixed that.

Then it said:

Maxwells Motor Parts
Your Order Inventory:

Order processed at 20:03, 30th April
Your order is as follows
1 tyres
2 cans of oil
3 spark plugs

here's the code. I don't know how many of the errors I got that you got, but you shouldn't get them with this.

<html>
<head>
<title> Your Order</title>
</head>
<body>
<h1>Maxwells Motor Parts</h1>
<h2>Your Order Inventory:</h2>
<?
echo "<p>Order processed at " ;
echo date("H:i, jS F");
echo "<br>";
echo "Your order is as follows" ;
echo "<br>";
echo $_POST['TyreQty'] . " tyres<br>";
echo $_POST['OilQty'] . " cans of oil<br>";
echo $_POST['SparkQty'] . " spark plugs<br>";
?>
</body>
</html>

how do i not use global variables?

does that mean i have to declare each variable at the top of the php script in a similar way to visual basic?

so hang on...not use global variables....thats the $post isn't it? why is it bad to use them, and in that case, how can i get round the problem?

*sits there confoosed*
