I’ve got it!
Instead of running another full query – I just ran a local foreach.
<ul class="package">
<?php
$args = array(
'post_type' => 'page',
'meta_query' => array(array(
'key' => 'package-creator',
'value' => '"' . get_the_ID() . '"',
'compare' => 'LIKE'
)
));
$getmysiblings = new WP_Query($args) ?>
<?php if ($getmysiblings->have_posts()): ?>
<?php while ($getmysiblings-> have_posts()): $getmysiblings->the_post(); ?>
<?php // get the relationship field ?>
<?php
$siblings = get_field('package-creator');
foreach($siblings as $sibling) {
$sibling_name = $sibling->post_title; ?>
<li><a href="<?php echo post_permalink($sibling); ?>"><?php echo $sibling_name; ?></a></li>
<?php } ?>
<?php // end get relationship field ?>
<?php endwhile; ?>
<?php wp_reset_postdata(); ?>
<?php else: ?>
<?php endif; ?>
</ul>
