Ah thanks John that makes sense,

I will try and add a tax_query into the query and switch taxonomy/term value to belong to a field in the field group.

FYI – The first section of your code in that posts caused a syntax error, heres the adjusted code that resovles the error.

add_filter('acf/load_field/name=hidden_post_id', 'make_hidden_post_id_readonly');
function make_field_readonly($field) {
  // sets readonly attribute for field
  $field['readonly'] = 1;
  return field;
}
add_filter('acf/load_value/name=hidden_post_id', 'set_hidden_post_id_value', 10, 3);
function set_hidden_post_id_value($value, $post_id, $field) {
  // set the value of the field to the current post id
  return $post_id;
}

Working through your steps now hopefully I’ll have this working soon 🙂

Thanks again!
