Works like a charm.

Thank you @geouser for a very informative answer. However, I seemed to have stumbled upon another problem. Using your code the filter_function_name is not being called at all

@TomJNowell I am not sure how this can be done for every post has different authors.

@geouser I have thought about it but did not know how to stop the deletion if need be

This should be the accepted answer

Thank you for your answer. Unfortunately, it has nothing to do with my question. The missing ' is present only in the question (The site will not have been loading if it was missing). And ugly code, in this case, is not the issue.

I have to say that I am not sure which answer to mark as the answer. Yours or mine.

Thank you. That really helped me find the complete answer: $args = array('category' => $wp_query->get_queried_object_id(), 'posts_per_page' => -1, 'orderby'=> 'title', 'order' => 'ASC' , 'post_type' => array( 'post', 'attachment'),'post_status' => array( 'publish', 'inherit')); $glossaryposts = get_posts( $args );
