Problem: I would like to know how to link a User and a post using Toolset.
Solution: Since Toolset's post relationships only work between posts, you can use a proxy post type to represent Users. For example, a post type called "Players". Each User will be the author of one Player post. Then you can use post relationships to link Players and other post types.
Problem: I am using a PHP script to loop over posts and display information from those posts. I would also like to display custom field information from a related post parent in the loop.
Solution: Use the toolset_get_related_post API to determine the parent post ID, then use that ID in the Types field API types_render_field to display the custom field value from the parent post.
The issue here is that the user wanted to create dependent parent fields in Toolset Forms.
Solution:
Unfortunately it is not possible to create dependent fields in our Toolset Forms plugin. Parent selection fields are not programmed to be dependent on another parent field selection
