I have my blog posts set up so that it shows a blog roll of other posts at the bottom. I am trying to hide the current post that the user is on from the other posts as it would not make sense to appear there.
The problem I am having is that it is hiding the first blog post from the blog landing page also. I am using the following code in my functions.php file:
add_action( 'pre_get_posts', function ( $query ) {
// not an admin page and not the main query
if ( ! is_admin() && ! $query->is_main_query() ) {
$query->set( 'post__not_in', array( get_the_ID() ) );
}
} );
