Computer Configurator

**nvening** · 02-07-2006, 03:06 PM

But i dont need to to select only am2 motherboards with an am2 chip as there will be a seperate AM2 configurator.

well, you could do it that way, but one way or another you need javascript anyway to do this effectively. HTML/XHTML has no room for logic what so ever.

**nvening** · 02-07-2006, 03:13 PM

logic? (sorry n00b here)

EDIT: also what did u say was wrong with the mailform code?

**aidanjt** · 02-07-2006, 03:33 PM

Logic, as in programming logic, lets say you decide that a basic HTML form emailed to you isn't good enough, and you decide you want to add on price calculations as the form changes, you need javascript to do that properly, orrr, if you want to add components later on, it's much easier to have a php/mysql script that lets you add things on via an administration form, thus saving you having to edit the html, save, reupload, and hope users browsers download the new copy.

Code:

<form emailto="mailto:nvening@gmail.com" application/x-www-form-urlencoded method="post" action="http://www.qkxyq.com/thalasson/mailform.cgi">

that part, emailto isn't a legal (html standards) <form> attribute and application/x-www-form-urlencoded should be enctype="application/x-www-form-urlencoded", however, it isn't really needed.

I deleted all that not needed stuff - i forgot to get rid of it in the first place.

The Hidden setting however is not valid but works in internat explorer and firefox so does it really matter??

**aidanjt** · 02-07-2006, 03:46 PM

no, the type=hidden attribute is perfectly valid.. it matters as in standards allow any HTML complient web browser, not all browsers allow a page to crap itself like I.E. does. it doesn't hurt to take a closer look at standards to make sure your webpage will work with the broadest possible audiance.

Here's a reference sheet to give you a hand with that: W3Schools - HTML 4.01 / XHTML 1.0 Reference

**nvening** · 02-07-2006, 03:51 PM

Thats strange - a minute ago i checked it with the validator and it said that all my hidden tags were invalid lol

sound.

**nvening** · 02-07-2006, 04:44 PM

I have found some Java code on the net and have edited it to make it sutable for my needs. However the code did not originally work (even though the guy though it did) but it would be perfect for my needs.

Can any of you java experts see whats wrong?

(the problem is that it does not total up the values)

Code:

<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN"

<html>
<head>
<title>Untitled Document</title>
<meta http-equiv="Content-Type" content="text/html; charset=iso-8859-1">
</head>

<body>

<SCRIPT language="javascript">
function cent(amount) {
     return (amount == Math.floor(amount)) ? amount + '.00' : (  (amount*10 == Math.floor(amount*10)) ? amount + '0' : amount);
}

function calculate() {
    var p1, p2, p3;
    p1 = test.price1.value * 1;
    p2 = test.price2.value * 1;
    p3 = test.price3.value * 1;
    total_price = p1 + p2 + p3;
    test.total_price.value = cent(Math.round(total_price*Math.pow(10,2))/Math.pow(10,2));
}

</SCRIPT>

<form name="test" method="post" action="http://www.qkxyq.com/thalasson/mailform.cgi">

i can't see any java - only javascript, which is an entirely different language

one thing to remember is that javascript rarely works between browsers - msie, mozilla, safari, etc all have different ways of referencing objects in a page

**ajbrun** · 02-07-2006, 04:57 PM

How are you going to be storing your data? I've seen no mention from you about a database or anything like that.

**nvening** · 02-07-2006, 05:07 PM

The prices and everything is to just me put directly into the code as thats the most practicle ting to do.

Sorry i meant java script - my bad - so i should not use javascript or what?

EDIT:

OK basically this is my problem: I am fine with the solution i have come up for the form and sending the data and everything.

The only other thing i need to do is add a totalling feature - i read through the PHP tutoral and am not sure if PHP could be used or what to look at for this to work.

Im sorry for keeping on about this.

Are you sure that's the most practicle thing to do? It's probably the easiest, but I really don't think that's the best solution at all. I'm not sure what others think, but I'd say a database would be the way to go. You could then easily do your totalling thing through PHP from the database.

**nvening** · 02-07-2006, 05:19 PM

Well it really only is a small and simple thing that i want to do - i did look at the mysql tutorial though but i dont really get why it keeps on about the code when you can use a gui to do it?

**ajbrun** · 02-07-2006, 05:26 PM

You could use a GUI to do it, but then it wouldn't be dynamic. If it's just a small thing, then it might not matter so much, but think what you'd do if you were doing something bigger. You'd need the code the insert, delete and search data using PHP. I didn't know the scope of your project, so I assumed it was something big. Although I'd still consider it even though it's small.

Can I ask what exactly it's for? Is it a small Uni project, or something you're being paid to do by a company? If it's for a company or anything like that, I really would consider using a database and making it as expandable as possible. If they came back to you in month time asking for them to be able to add new products into the system, then a database would definatly be needed then.

**nvening** · 02-07-2006, 05:55 PM

Its just a small project tbh - its not for anyone else - i dont want to mkae it complicated and the like just want to get it to total.
