Calculations in forms

[eejaybee]

I am trying to write a simple html form and PHP form-handler. Before the user submits the form, some simple on-the-fly calculations are needed.

For example, if he or she requests 2 of item 1 @ £1.50 the total cost of £3.00 is displayed on the screen and so on down a list of 6 items, after which a total cost is displayed. The user then fills out his or her contact details and submits the form.

Can I use PHP to do the on-the-fly calculations, or do I need to use client-side scripting such as Java?

You'll need to do it on the client side, although you can bring PHP into the picture using AJAX techniques.

But, on the client side, there's really no need for this problem to involve Java. You could handle it quite easily with javascript.
