You have 2 problems. The global $post value is not set at ‘init’ and this means that ACF does not know what post to get the value from.
The soonest you can to this is the ‘wp’ hook.
add_action( 'wp', 'redirect_product' );
The next thing you need to do is tell ACF what post to get the value from because it still can’t know because this is outside of “The Loop”
$queried_object = get_queried_object();
if (!is_a($queried_object, 'WP_Post')) {
// not a post
return;
}
$post_id = $queried_object->ID;
// I would also probably check the post type here
if (get_post_type($post_id) != 'My Post Type') {
return;
}
$redirect = get_field('linked_book', $post_id);

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
