Post Custom Field

Note: This field cannot be used with the Advanced Post Creation Add-On. If utilizing that plugin for post creation, use a standard field type instead.


The Post Custom Field allows users to submit data that is then used to populate a custom field value for a post. This field works in tandem with the other Post fields to allow you to create a form that can generate post data from a user submission. It is available under the Post Fields section within the form editor.
