I think you’ll have to pass along the current posts id as well (or use global $post)..
<?php
function example($field, $postID) {
$post_object = get_field($field, $postID);
if($post_object) {
# get post data
$post = $post_object;
setup_postdata($post);
?>
<h3><a href="<?php the_permalink(); ?>"><?php the_title(); ?></a></h3>
<?php
# reset postdata
wp_reset_postdata();
}
}
example('my_post_object', $post->ID); //in your template, assuming you do this inside the loop. If outside try replacing $post->ID with get_the_ID()
?>
