ACF关系字段搜索包括自定义字段

Question

I am using the code below to modify the acf/fields/relationship/result in order to include extra field data to the list. However, this data is not searchable if I use the relationship field's search feature. Can anyone come up with a way I can extend the search function to include this data? I understand I have to use acf/fields/relationship/query to do this, but I do not know how.

Here is the code that adds the relevant data to the list:

function id_relationship_result( $title, $post, $field, $post_id ) {
  // load a custom field from this $object and show it in the $result
  $city = get_field('city', $post->ID);
  $state = get_field('state', $post->ID);

  // append to title
  $title_new = $state . ', ' . $city . ' ' . $title;

  // return
  return $title_new;
}

Any help is appreciated....

You're not too far off here - you just need to use a different ACF hook. To modify the title on return, you have to use the ACF acf/fields/relationship/result hook - which is explained here - http://www.advancedcustomfields.com/resources/acf-fields-relationship-result/

So, in your case here, you could add the following to your functions.php file

add_filter('acf/fields/relationship/result/name=your_relationship_field_name', 'id_relationship_result', 10, 4);
function id_relationship_result($title, $post, $field, $post_id){
    // load a custom field from this $object and show it in the $result
    $city = get_field('city', $post->ID);
    $state = get_field('state', $post->ID);

    // append to title
    $title = $state . ', ' . $city . ' ' . $title;


    // return
    return $title;
}

That will hopefully allow your title to list the data you need and allow for easier filtering
