Need some input from others.
I have a form (edit-this.php) that is used to edit a single-post type.
And in my field group I have a field that I want to use prepare_field and need to pass the post_id to.
Trying not to use the post_type-single.php for this post type if I can help it.
If I use get_the_ID(), it will return the ID of the page.
Thoughts or ideas?
You are correct, I think. In your prepare_field filter you need to get the post ID. What you posted is one method of doing that.
