In this chapter, we discussed the advanced usages of custom post types to suit web application functionalities. Now, I would recommend that you try out the following tasks in order to evaluate the things you learned in this chapter:
- In the post relationships section, we enabled relationships using the join_topics_to_forums function. With the use of this function, we can generate a new problem considering the possibility of extending. Find the issue and try to solve it by yourself.
- We enabled relationships between custom post types. Research the possibilities of including metadata for relationships.
