Hi everyone, our teams are implementing the unfinished form saving for multi-page form, which was topic mentioned by a few people before. We managed to create a few functions to create a draft of custom post which we use to store the form data, and updating the data when going to the next page. All the form fields are stored as custom fields in the custom post. The custom post will be published when the form is selected.
Now the problem we are facing currently is that, we can't figure out a way to repopulate these fields back into the empty form, I wonder if anyone who might have experience implementing similar function may help or pointing us the direction we can look.
