I am trying to: Sorting my view (Parent=House) , not on the contents of a parent field , but depending on whether there is or there is not a child (Room) present ?

For example:

House1 Room1
House2
House3 Room3
House4 Room4
House5

The list I want to create I would like to display looks then:

House1 Room1
House3 Room3
House4 Room4
House2 <- has no childeren, so display this one after the parents with children.
House5 <- has no children

I don't know how to do this?

Thank you for contacting Toolset support, I'd be delighted to assist!

To query if a parent object has children, you would need a custom shortcode such as:

function has_children_of_type( $atts ) {
    global $post;
    extract( shortcode_atts( array(
        'post_type' => 'TYPE', // Make sure to set the correct post type
    ), $atts ) );
    $parent_type = $post->post_type;
    $childargs = array(
        'post_type' => $post_type,
        'numberposts' => -1,
        'meta_query' => array( array( 'key' => '_wpcf_belongs_'.$parent_type.'_id', 'value' => $post->ID ) )
    );
    $child_posts = get_posts( $childargs );
    return count( $child_posts ) == 0 ? false : true; 
}
add_shortcode( 'has_children_of_type', 'has_children_of_type' );

Then go to Views > Settings > Compatibility > Third-party shortcode arguments and add the shortcode.

You can then use it in your views using something like the following:

[wpv-conditional if="( '[has_children_of_type post_type="testimonial" ]' eq '1' )"]
              CONTENT
[/wpv-conditional]

If needed, you can nest views within views as well: https://toolset.com/documentation/user-guides/using-a-child-view-in-a-taxonomy-view-layout/

I will close this thread , read your instructions and when I have questions again, I will make a new thread.
