I am getting somewhere – now what I am struggling with is getting a value via PHP of an acf input field. The $_GET method doesn’t seem to be working, not sure if it is because the name is actually an array element… This is what I am trying to get working –
<?php update_field('image_selection', $_GET['acf[field_571a8e724a917]']); ?>
The get should be returning a number.
