I'm working on a checkout process for a takeaway restaurant where anonymous visitors can place orders using guest entries.
In this stage the order is saved with a status of "unpaid". Once a visitor saves the order he's taken to a payment provider service where he pays for his order, once the order is payed the visitor is redirected to a page where the order status would be set to "paid" in a hidden form.
In order to accomplish this the aforementioned saved guest entry would have to be edited from the front-end. Is it possible to anonymously edit an entry?
