Script form to do math

Copy linkTweet thisAlerts:
Dec 13.2004

I need to create a form that looks like a basic invoice. You choose a size and color, add a quantity, and based on the model number, it puts in a unit price and calculates the info automatically based on quantity. Then it can be submitted via email.

Any ideas where to get a script like this?

I appreciate any help.

Thanks!

@ExuroDec 14.2004 — You just need to grab the values of the fields, and either parse them to do math with them or equate a number into your equation based on that value. There really isn't much else that can be said without more detail on your problem though. However, you should really at least provide an alternate method for generating the price server-side in case the user does not have JavaScript enabled.

That's why you do the calculations server-side. You can do the initial calculations client-side to save on server resources, but the final number should always be done by the server to avoid users hacking.

Success!
