Problem: I would like to create multiple Content Templates using an existing Content Template as the starting point so I don't have to recreate the design over and over.
Solution: Use the Duplicate feature in the Content Templates list to create a clone of an existing template. Hover over the CT title to see the Duplicate link.
Solution:
No.
"cred_save_data" hook belongs to Toolset forms and it will only triggered when you submit the form that is created using Toolset.
If you are using another plugins using which you created user form, you should check with that plugin support if they offer any hook that you should use to hook your custom code.
Problem: I would like to use a conditional to test whether or not a parent post exists for the current post (child) in a specific post relationship. In the past, I had a conditional that worked well by testing the hidden custom field _wpcf_belongs_restaurants_id on the child post, but it seems this is no longer working. The custom field does not exist in the database for the child post.
Solution: After migrating post relationships, the _wpcf_belongs_{parent-post-type-slug}_id custom field value is no longer reliable for determining the parent post. Post relationships now rely on custom database tables to establish relationships, so conditionals testing the old hidden custom field are no longer valid. Instead, you can test for the post ID of the parent post in a conditional using the wpv-post-id shortcode and item="@relationship-slug.parent" syntax:
[wpv-conditional if="( '[wpv-post-id item="@relationship-slug.parent"]' ne '' )"]
parent exists
[/wpv-conditional]
