Here are the steps:
1. select post to edit
2. select image field and select image
3. once selected, on the change event (from your example – thanks!) update a text field with the id of the image
4. then get this id value via PHP (my code that doesn’t work) so that I can access the URL of the newly selected image.
I am no PHP expert so not sure if I can really call a PHP script multiple times or if PHP is really only called once.

ACF wouldn’t be so widely used in WordPress if it didn’t have some pretty amazing capabilities. In this article, we look at a few of the features we’ll discuss during “7 things you didn’t know you could do with ACF” at #WPEDecode later this month. https://t.co/5lnsTxp81j pic.twitter.com/Yf0ThPG1QG— Advanced Custom Fields (@wp_acf) March 16, 2023
