Hello. Thank you for contacting the Toolset support.

Well - to order parent post by number of count of it's associated child posts you need to add some custom code.

Could you please tell me your child post type name?

Basically, you should create a Types numeric filed namely "child-count" for your parent post type "Game" which will hold the count of your child posts and save the total count while add/delete your child posts.

For example:

add_action( 'before_delete_post', 'count_total_children_delete' );
function count_total_children_delete($post_id)
{
    if ( get_post_type( $post_id ) == 'child-post-type-slug' ) {
        $parent_id = get_post_meta( $post_id, '_wpcf_belongs_game_id', true );
        if($parent_id != '')
        {
            $childargs = array(
                'post_type' => 'child-post-type-slug',
                'numberposts' => -1,
                'meta_key' => '_wpcf_belongs_game_id',
                'orderby' => 'meta_value',
                'order' => 'ASC',
                'meta_query' => array(array('key' => '_wpcf_belongs_game_id', 'value' => $parent_id))
            );
            $totalChildCount = count(get_posts($childargs));
 
            update_post_meta( $parent_id, 'wpcf-child-count', $totalChildCount);
        }
    }
}
 
add_action( 'save_post', 'count_total_children',20,2);
function count_total_children($post_id){
    if ( get_post_type( $post_id ) == 'child-post-type-slug' ) {
        $parent_id = get_post_meta( $post_id, '_wpcf_belongs_game_id', true );
        if($parent_id != '')
        {
            $childargs = array(
                'post_type' => 'child-post-type-slug',
                'numberposts' => -1,
                'meta_key' => '_wpcf_belongs_game_id',
                'orderby' => 'meta_value',
                'order' => 'ASC',
                'meta_query' => array(array('key' => '_wpcf_belongs_game_id', 'value' => $parent_id))
            );
            $totalChildCount = count(get_posts($childargs));
 
            $oldChildCount=get_post_meta( $parent_id, 'wpcf-child-count', true );
            if( $totalChildCount != $oldChildCount ){
                update_post_meta( $parent_id, 'wpcf-child-count', $totalChildCount );
            }
        }
    }

Where:
- Replace 'child-post-type-slug' with your original child post type slug

Now,
create a view listing your parent custom post type posts, order it by the custom field "child-count" (descending) and list your parent posts.

Ok - as I understand CPT game have been assigned with 5 child post types .

Now, question is, you want to have total child count irrespective of any child post type or the count should be setup as particular child count belongs to each child post type?

    if (in_array(get_post_type( $post_id ),$post_type_array) ) {
        $parent_id = get_post_meta( $post_id, '_wpcf_belongs_game_id', true );
        if($parent_id != ''){
            $totalChildCount = get_post_type_count($parent_id );

$count_childs = array();
foreach($post_type_array as $k=>$v):

$childargs = array(
                'post_type' => $v,
                'numberposts' => -1,
                'meta_key' => '_wpcf_belongs_game_id',
                'orderby' => 'meta_value',
                'order' => 'ASC',
                'meta_query' => array(array('key' => '_wpcf_belongs_game_id', 'value' => $parent_id))
            );
           $count_childs[]  = count(get_posts($childargs));
endforeach;

       return array_sum($count_childs);     
  
}

*** Please make a FULL BACKUP of your database and website.***
I would also eventually need to request temporary access (WP-Admin and FTP) to your site. Preferably to a test site where the problem has been replicated if possible in order to be of better help and check if some configurations might need to be changed.

I would additionally need your permission to de- and re-activate Plugins and the Theme, and to change configurations on the site. This is also a reason the backup is really important. If you agree to this, please use the form fields I have enabled below to provide temporary access details (wp-admin and FTP).

I have set the next reply to private which means only you and I have access to it.

Looks good.

How can I update the count for all old games?

Thanks

Well - There is no automatic way to do that. you need to build and run a script or you need to save any child post type having different game post at least once.
