My client wants a Samples Request form that when an item is selected it will be added to a list. It would be sort of like a shopping cart but nothing is actually purchased so a shopping cart would be overkill. They just want whatever sample items are selected on the form to appear on a page and then when submitted that info is passed on to my client so they can ship the sample(s) to their prospective customer.
I have used FormMail PHP and am thinking that PHP could handle this type of scenario but have no idea how implement it. Where I'm lost is how to show the selected items before processing the form.
