@mfgrijs All ACF filters and actions should do some basic checking, yes you can use the same code for multiple post types.
add_action('acf/save_post', 'FUNCTION_NAME');
function FUNCTION_NAME($post_id) {
$post_type = get_post_type($post_id);
if ($post_type != 'tv' && $post_type != 'radio')) {
// not your post type
// do not run
return;
}
// .... more code here
}
