I often need to create post titles in WordPress based on fields I’ve generated using Advanced Custom Fields. Below is an example that assumes we have a Custom Post Type registered to “staff” and two Custom Fields with the name of “first_name” and “last_name”. Using the “update_value” hook provided by Advanced Custom Fields and “wp_update_post” I am able to update the Slug and Post Title using the values given in the respective fields.
To disable the Title field I remove it from the
supports argument for the
'supports' => array( 'editor', 'thumbnail', 'revisions', 'page-attributes' ),
Disabling the title at a custom post type level will, unfortunately, remove the clickable permalink below the title that I often use. To combat that I create a very simple metabox with the permalink. Demonstrated below. (I believe this is no longer the case with Post Types using the Block Editor)
