Specifically, I'm trying to get get the 'Layout Group' of a given ThemeREX Custom Layout (which as I understand is just a Custom Post Type), but am also interested in seeing what other properties are available for that post.
I tried
print_r(get_post_meta(get_post(1738, 'ARRAY_A', 'display'),"",true));
but all that was returned was the number 1.
I'm guessing the meta is not what I'm looking for. Is there a way to iterate through all the custom properties that are registered with that post's CPT?
