Recently I had a client who wanted a registration form for their upcoming conference where the guest could select from a bunch of add-on options. At the end of the form, right before the guest is prompted to make their purchase, Gravity Forms allows for only a simple 'total' field. We felt that this was insufficient, so I created a neat little plugin that will summarize all of the Products in your form, and output the guests choices for them to review.
Here it is! Include this as a new file in your theme or plugin.
IMPORTANT: This plugin works ONLY if you’re using pagination on your form. If you are not, simply add pagination in such a way that the final page of your form is your ‘cart review’ page, and make sure you include a Total field, and a payment option field.
