I am trying to import two spreadsheets as two separate, but related CPT's, and the two options that I have for connecting a related CPT is either by inputting the Post Title, or Post ID of the related post. Post Title is not possible to use for me since there are a bunch of Post Title's that are exactly the same wording and it will create anomalies, so I need to work with the Post ID.
The customer asked what is the difference between storing a post title and showing the title using the heading block.
Solution:
Guided that post title is saved in the database as a name of the post, whereas the heading block is a tool to show any heading, including the post title.
