Return a custom field in functions.php

I’m sure this is something simple that I just don’t know how to do. I’m using a plugin to autocomplete my search field and I’m customizing the link that returns using the code below.

add_filter( ‘search_autocomplete_modify_url’, ‘saModifyURL’, 10, 2 );

function saModifyURL( $link, $object ) {
$newLink = ‘http://website.com/?Click=<?php the_field(“id_number”); ?>’;
return $newLink;
}

My issue is I need to return the custom field “id_number” that is associated with the result into the link. I found the documentation on doing this on it’s own but is it possible to mix them together to return that in my result?

You will need to get know what post or where you’re getting the field from and supply the value in the second of…. and you’ll also need to use get_field() which I just noticed. the_field() echoes the value so first try

add_filter( 'search_autocomplete_modify_url', 'saModifyURL', 10, 2 );

function saModifyURL( $link, $object ) {
  $newLink = 'http://website.com/?Click=<?php get_field("id_number"); ?>';
  return $newLink;
}

if that does not work then figure out how you’re going to supply the post id

get_field("id_number", $post_id);

side note, use back ticks to include code, or click the code link at the top of the editor.

Thanks for your help. I ended up going a different route that didn’t require hotlinking.
