When users sign up, they get 2 weeks free access, after which I need to collect their banking details. If they want to, they can add them on sign up as well.
When a user logs in, I am checking whether the 2 weeks are over. If it is and they have not added their banking details, I am forwarding them to a page, where they can add their banking details. I want them to edit their original sign-up entry, but they should only be able to change the "banking details" fields.
I have read these instructions - https://formidableforms.com/knowledgebase/set-up-front-end-editing/ - but I just want to show the form and the entry, not a list of entries.
How can I embed a form on a page, prefilling the entry the user made, making just the banking details field editable?
P.s. for simplicity's sake, a user can only have entry for the sign-up form.
