Maybe a simple question, but I can find the answer. I add a Frontend Submission form to an single page. It shows, but is empty because the post_id is not set.
Where and how do I add these? Can you give me the steps? I now use WSForms for this but I will learn Metabox owns Frontend Submission.
Do you mean to pass the post_id attribute to the frontend form to update the current page in the form? If you want to pass the ID of the current page, set it to current.
