Hello,
I have also to use the code in the php file
<?php
new my_dynmamic_field_on_relationship();
// you should probably change the name of this class and
// modify the statement above that instantiates it
class my_dynmamic_field_on_relationship {
public function __construct() {
// enqueue js extension for acf
// do this when ACF in enqueuing scripts
add_action('acf/input/admin_enqueue_scripts', array($this, 'enqueue_script'));
// ajax action for loading values
add_action('wp_ajax_load_relationship_content', array($this, 'load_content_from_relationship'));
} // end public function __construct
public function load_content_from_relationship() {
// this is the ajax function that gets the related values and returns them
// we can use the acf nonce to verify the request
if (!wp_verify_nonce($_POST['nonce'], 'acf_nonce')) {
echo json_encode(false);
exit;
}
// check for our other required values
if (!isset($_POST['post_id']) || !isset($_POST['related_post']) || !isset($_POST['image_size'])) {
echo json_encode(false);
exit;
}
// post IDs must be integers
$post_id = intval($_POST['post_id']);
$related_post = intval($_POST['related_post']);
// get the image size to return
$image_size = $_POST['image_size'];
// you need to replace all field names in all of the following code
// with the field names of your fields
// first check to see if the selected related post is the same
// as the current value for the related post
// if it is return values that have already been saved for this post
// the 3rd parameter set to false returns unformatted value
$value = get_field('relationship', $post_id, false);
// relationship fields always returns an array
// use the first value of the array
$value = intval($value[0]);
if ($value == $related_post) {

// return values that were previously saved for the fields
// get the image, if any
$image = false;
$image_id = intval(get_field('relationship_image', $post_id, false));

/* *** THIS IS IMPORTANT
ACF uses the same scripts as well as the same field identification
markup (the data-key attribute) if the ACF field group editor
because of this, if you load and run your custom javascript on
the field group editor page it can have unintended side effects
on this page. It is important to alway make sure you're only
loading scripts where you need them.
