Display post type's plural label?

use $obj->labels->name instead. It’ll tap into the label fields.

Tried:

<h1><?php $obj = get_post_type_object( 'wedding-logos' );
echo $obj->labels->name; ?></h1>

Didn’t work.

are you sure you’re working with a post type here? I saw above that you mentioned category slug, which would be taxonomy stuff rather than post type.

Use the print_r() function on your $obj to see what you’re getting out of things.

You’re right, my colleague changed the slug. Thanks much!

Welcome.
