Hi,
I need to expand the search in relationship query to search for both title or custom field named “reference”. This is my functions.php but not work 🙁

function modify_acf_relationship_search_query ($args, $field, $post ) {
$args[‘meta_query’] = array(
array(
‘key’=> ‘reference’,
‘value’=> $args[‘s’],
‘compare’ => ‘LIKE’
)
);
return $args;
}

add_filter(‘acf/fields/relationship/query’, ‘modify_acf_relationship_search_query’, 10, 3);

I can also serve a search by title and post ID (the reference is the post id followed by a letter)

Can someone help me?

(Sorry for my english)

In order to change this you need to add a pre_get_posts filter that will run for the query.

Here is one solution for modifying the search https://wordpress.stackexchange.com/questions/99849/search-that-will-look-in-custom-field-post-title-and-post-content

The best way to add the filter would be something like this

add_filter('acf/fields/post_object_query/name=your_field_name', 'add_my_pre_get_posts_filter', 20, 3);
function add_my_pre_get_posts_filter($args, $field, $post_id) {
  // this will cause the pre_get_posts filter to be added only for this query
  // add filters that will modify the queries here
}

// this is an example of one filters used to make the needed changes
function some_function_name($args) {
  // remove this filter so it will not be run on subsequent queries
  // it is called with the same arguments you used to add this filter
  remove_filter('the_hook_for_this_filter', 'some_function_name');

  // the rest of the filter here
}
