List latest posts with least comments in WP-Admin

I managed to figure it out. So, get_posts() uses WP_Query() and we can use the example in the documentation to filter the dates.

Now for the comments, that is easy, we just add the parameter 'orderby'=>'comment_count'. Also to note, when filtering get_posts(), we will need to disable suppress_filters.

Let’s filter the time first:

function filter_where( $where="" ) {
    // posts in the last 2 days
    $where .= " AND post_date > '" . date('Y-m-d', strtotime('-2 days')) . "'";
    return $where;
}

And now let’s get the posts:

add_filter( 'posts_where', 'filter_where' );
    $query = get_posts(
        array (
         'numberposts' => 2,
         'orderby'=>'comment_count',
         'order'=>'ASC',
         'suppress_filters' => false,
         'post_type'   => array ( 'post' )
        )
    );
remove_filter( 'posts_where', 'filter_where' );

That will give you the top least commented posts from the past 2 days.
