get_field() not working in standalone PHP file

Hello there – I’m pretty new to WordPress development so apologies if I’m misunderstanding any basic fundamentals here. My site is currently hosted locally, and I’m trying to update an ACF repeater field dynamically.

I have a page that runs this code:

url: 'http://localhost:8888/wordpress/wp-content/themes/cookable/write-course-to-user.php',data:{"userIDdata":finaluserid, "courseURLdata":tidycourseurlupdate},
 success: function(data) {
   $('#result3').html(data);

 }
});

And then write-course-to-user.php – a standalone PHP file – contains:

<?php

$userIDfinal = isset($_REQUEST['userIDdata'])?$_REQUEST['userIDdata']:"";
$courseURLfinal = isset($_REQUEST['courseURLdata'])?$_REQUEST['courseURLdata']:"";

  $field_key = "field_61e9bb8b66765";
  $value = get_field($field_key, "user_{$userIDfinal}");
  $value[] = array("course_slug" => $courseURLfinal);
  update_field( $field_key, $value, "user_{$userIDfinal}");

?>

However I’m getting errors:

Call to undefined function get_field()

I assume that the ACF/Wordpress functionality is not working in the standalone file. I’ve tried adding:

include('http://localhost:8888/wordpress/wp-config.php');
include('http://localhost:8888/wordpress/wp-load.php');
include('http://localhost:8888/wordpress/wp-includes/pluggable.php');

but still no joy. If anyone could point me in the right direction here I’d be very grateful.

Thanks so much.
