Ok thanks!! John..
This is what works!!
function on_post_save( $post_id) {
//Get previous values.
//$prev_values = get_fields( $post_id );
//Get submitted values.
//$values = $_POST['acf'];
$post = get_post( $post_id );
$output = apply_filters( 'the_content', $post->post_content );
if($output):
$post_content = html_entity_decode($output);
$dom = new DomDocument();
@$dom->loadHTML($post_content);
$attachment_ids = array();
foreach ($dom->getElementsByTagName('a') as $item) {
$attachment_ids[] = $item->getAttribute('data-id');
}
//var_dump($attachment_ids);
// die();
if($attachment_ids):
update_field('field_63a6bd5d2a3d2',$attachment_ids, $post_id);
else:
update_field('field_63a6bd5d2a3d2',"", $post_id);
endif;
else:
//clear all attachments if no content is available
update_field('field_63a6bd5d2a3d2',"", $post_id);
endif;
}
add_action('acf/save_post', 'on_post_save', 10);
