Hello

With this code I can change the names of registered advertisers, but not guest advertisers.

I would like the guest advertiser’s name to remain the original.

How to solve?

add_filter( "adverts_tpl_single_posted_by", function() {
	if( get_post( $post_id )->post_author > 0 ) {
  return '[publishpress_authors_box layout="inline" show_title="false"]';
    } else {
		
	return "<span style='color:red'> Guest <strong>%s</strong></span>";
        
    }
  
} );
