Is This Logic Sound?

Hi,

I have an order form that will capture things like name, email, quantity ordered, options, etc. I want to take that information, pass it to another form via $_POST, do some calculations based on the info, and present to the user a confirmation page. If they agree the order is correct, they hit confirm, and are taken to a summary page with the whole order, so they can print it, and an email is sent to the site owner.

I believe that I should do the calculations on the confirmation page itself. But I wonder...if they agree everything is good, and hit confirm, will the new variables get passed to the summary page if I list them as hidden variables in the form I have created to house the "Confirm" button?

For some reason, this flow just doesn't seem right. I have the transition from order page to confirmation page working, but it seems like I'm heading down the wrong path for the rest. Any recommendations on how to best address this?

Thanks!

Mark

Use sessions (ref: [man]session[/man]) to retain the data from one page to the next.

Unless you need the results of the calculations on the confirmation screen, you might as well leave off doing them until the user has confirmed the information; otherwise it's just extra work for no benefit.

Hi,

I'll check out sessions...thanks!

I do need the results of the calculations for the confirmation page, since they pick quantities of product, and I have to calculate subtotal, tax, and total based on the quantities.

Thanks!
