Query by meta_value_num and date?

Hi!

First of all, thanks for a great plugin! I posted this question on the github page, but then I realised that the plugin was listed here again, so I decided to post it here as well. I guess it’s the more appropriate place.

This is my code to fetch child posts inside a single post template, which works, except for one thing:

<?php
$initial_count = get_post_meta($post->ID, '_initial_count', true);
$images = get_children('post_parent='.$post->ID.'&post_status=publish&post_type=user_images');
if ( ! empty( $images ) ) {
    $image_ids = wp_list_pluck( $images, 'ID' );
    $image_ids = implode(',',$image_ids);
 echo do_shortcode('[ajax_load_more post_type="user_images" preloaded="true" preloaded_amount="'.$initial_count.'" meta_key="_point" post__in="'.$image_ids.'" orderby="meta_value_num" posts_per_page="20" pause="true" scroll="false" button_label="Ladda fler bilder..." transition="fade" container_type="div" css_classes="user-images"]');
}
wp_reset_postdata();
?>

Users can vote for posts on my site, and what I’m trying to do is to order the posts by the meta key “_point” (the number in this custom field).

It works for the preloaded posts, but when I load more, sometimes it displays some of the same posts as in the preloaded list.

I think there might be two possible explanations for this:

It could be a cache related issue, although I don’t think that would be the case.

or…

It could be that I also need to specify that it should posts with the same number of votes by publish date/time. Something like this:

$query->set('orderby', array('meta_value_num' => 'DESC', 'date' => 'DESC'));
Would this be possible?
