Hey, I'm learning PHP right now through a book that I was reccomended to get on the forum (PHP and MySQL Development - Welling and Thomson) and I have just completed this little project. It isn't much, but I'm very proud of it!

Basically, it's just something that it explains in the book. It is an order form for "Bob's Auto Parts" It takes what the person orders and puts it into a .txt file with a PHP script, and then you can view all customer orders with anoter php script. I used the code from the book, but I also added a bit of my own!

I have been reading the book for little under a week now, and I am quite happy with this project! The only thing that I'm unsure of is how to make it so that the quantities of, for example, tires isn't written to orders.txt if it is 0. Or, if there is only 1 tire being ordered, I'm not sure how to make it say 1 tire instead of tires without writing the whole $outputstring tons of times with if statements.

I would highly suggest you use a database rather than flat files.

I also prefer to inline the PHP rather than echo HTML but thats a style thing.

Also you have a large section on making sure plurals are used correctly. I would solve that problem by put "Tire(s)" and save myself some time. :p

MrMan9879 · Jan 2nd, 2006, 3:24 AM

Yeah, I suppose I could do "Tire(s)" but I wanted it to look better. Also, I will be using databases, like i said... I'm learning from a book, and the first half is just on PHP, and it hasn't gotten into MySQL yet. I'm only on chapter 2...

Polyphemus_ · Jan 2nd, 2006, 3:58 AM

One thing: it would be safe to check the post variable exists. It is handy to put this check in a function:
[php]
function getPost($v) {
return (isset($_POST[$v]) ? $_POST[$v] : "");
}

$tireqty = getPost('tireqty');
$oilqty = getPost('oilqty');
// ...
[/php]

MrMan9879 · Jan 2nd, 2006, 3:28 PM

Yes, I've heard of those functions. Next time I make a PHP script, I will try to add the check functions.
