get_comments() where parent is not 0
You cannot do that with a parameter for get_comments(), but filtering ‘comments_clauses’ should do it. Sample code, not tested: add_filter( ‘comments_clauses’, ‘wpse_78490_child_comments_only’ ); function wpse_78490_child_comments_only( $clauses ) { $clauses[‘where’] .= ‘ AND comment_parent != 0’; return $clauses; }
