Problem: I have a CRED form that allows users to create child posts. Using cred_save_data, I would like to create a custom post title using information stored in a custom field on the parent post.

Solution: In cred_save_data, you will be able to determine the parent post's ID using get_post_meta to access _wpcf_belongs_parentslug_id. Then you can get the custom field value using get_post_meta, the parent ID, and the custom field slug:

...
// get the parent ID from the child postmeta
$parent_id = get_post_meta($post_id, '_wpcf_belongs_parentslug_id', true);
// get the title from the parent postmeta
$custom_title = get_post_meta( $parent_id, 'wpcf-custom-field', true );
...
