  • function my_create_post_types() { register_post_type( 'my_post_type', $args); register_post_type( 'my_other_post_type', $args); } add_action( 'init', 'my_create_post_types' ); The first link and this function has to be combined in some way.

  • The idea is good for adding a field in one post type from other related post type.That is not what iam asking.Suppose we submit an answer for a question,how to relate that question & answer for displaying them correctly.Both questions & answers are seperate cpt.How to display corresponding answers when a question link is clicked.Please check this link shibashake.com/wordpress-theme/add-metabox-custom-post-type

  • Do you will display the answers to the questions in front end, 2 different CPTs? Or you will display this in a meta box inside the back end on the cpt question? But is not really different. The content inside the meta box or front end have the same loop to get the other CPT with the relationship from CPT "QuestioN" to CPT "Answer".
