Tell us what you are trying to do?
I have a custom post type, which I want to expire after 3 years (basically a user will pay for the right to have a document searchable on my website for 3 years). Is it possible in Toolset, that when a 'post' is input via the Post Form, that an expiry date is automatically added to the post which is 3 years after the date of the publish date?
Is there any documentation that you are following? I looked but couldn't find a suitable example
Is there a similar example that we can see? No
