Hi @hube2 Thank you so much for your response, I appreciate it

Upon using your code.

add_filter(‘acf/fields/relationship/query/name=related_tracks’, ‘remove_already_selected’, 10, 3);
function remove_already_selected($args, $field, $post_id) {
$query = new WP_Query(array(
‘post_type’ => ‘album’, // my assumption
‘post_status’ => ‘publish’,
‘posts_per_page’ => -1
));
$selected = array();
if (count($query->posts)) {
foreach ($query->posts as $post) {
$tracks = get_field(‘related_tracks’, $post->ID, false);
if (!empty($tracks)) {
foreach ($tracks as $track) {
$track = intval($track);
if ($track && !in_array($track, $selected) {
$selected[] = $track;
}
} // end foreach track
} // end if tracks
} // end foreach post
} // end if posts
if (!empty($selected)) {
$args[‘post__not_in’] = $selected;
}
return $args;
} // end function

There is error on this line ‘$selected[] = $track;’

the error is syntax error, unexpected ‘;’

Sorry im very newbie on coding.
