添加保护子句以防止修改其他查询很重要。（例如，菜单）。我们正在尝试修改这里的主查询，因此如果这不是主查询，我们应该退出。

function my_get_posts( $query ) {

    // Bail if this is not the main query.
    if ( ! $query->is_main_query() ) {
        return;
    }

    // Other guard clauses to ensure we don\'t affect queries unintentionally.
    // Sounds like you are just trying to target the homepage, so we could check for that too.
    if ( ! is_home() ) {
        return;
    }
    
    // We only need to modify the query for logged in users.
    if ( ! is_user_logged_in() ) {
        return;
    }
    
    // Modify the query as needed...

}
add_action( \'pre_get_posts\', \'my_get_posts\' ); // Note that pre_get_posts is an action, not a filter.
