Tell us what you are trying to do?
I have a one to many relationship - One Product can have many Experiences.

Assigned to the Experiences is a taxonomy cal XP Experiences

What I want to do is create a filter on the parent posts as follows:

1. Filter on parent posts (show all then filter) based on custom fields assigned to parent posts
2. Filter on parent posts (show all then filter) based on the CHILD posts taxonomy that are linked to the Parent Post

Filters 1 and 2 to be on the same view - so offer different filter options

Hi, in order to do this with front-end filters you would need to be able to filter upon fields or taxonomies of related post types. That's not currently possible. So right now you could either filter a View of parent posts by fields on the parent post, or you could filter a View of child posts by taxonomy terms on the child posts and display the parent post in the results using Views shortcodes, but there's no simple combination of both.

Another practical option I can think of is to duplicate data across both posts somehow, either by assigning the child post taxonomy automatically to the parent post or by assigning the parent field information to the child posts automatically. If you assign the parent field information to the child posts automatically, you could create a View of the child posts and display the parent Product information in the loop of the View. Here's an example of setting a custom field value on a child post automatically, based on the parent post, whenever the child post is saved:

add_action( 'save_post', 'auto_set', 100, 3 );
function auto_set( $post_id, $post, $update ) {
  if( $post->post_status == 'publish' && $post->post_type =='child-post-type-slug' ) {
    $parent_id = toolset_get_related_post( $post_id, 'post-relationship-slug' , 'parent', array() );
    $field_value = get_post_meta( $parent_id, 'wpcf-custom-field-slug', true );
    update_post_meta( $post_id, 'wpcf-custom-field-slug', $field_value );
  } 
}

Then in the loop:

Parent post: [wpv-post-title item="@post-relationship-slug.parent"]

My issue is resolved now. Thank you!
