I have a list of posts and Post One and Post Two has several post selected on the Relatioship Field.

This is my expected outcome:

Post One
Post 1.1
Post 1.2
Post Two
Post 2.1
Post Three
Post Four

I put the Post 1.1 and Post 1.2 as a relationship field under Post One. How can I query that Post 1.1 and Post 1.2 has been set from Post One using the Relationship field so that I can exclude it from the main list and not be duplicated?

What I can do right now is query Post One and then list Post 1.1 and Post 1.2 underneath it but but how will I know that Post 1.1 and Post 1.2 has been set from Post One?

With this code:

<?php
if( $rel ): ?>

” target=”_blank”>
<?php echo $thetitle; ?>

<?php foreach( $rel as $p ): // variable must NOT be called $post (IMPORTANT) ?>
• ID;?>” href=”<?php the_field(‘page_link’, $p->ID); ?>”><?php echo get_the_title( $p->ID ); ?>

<?php endforeach; ?>

<?php else : ?>

” target=”_blank”>
<?php echo $thetitle; ?>

<?php endif; ?>

From that code, other list are duplicated. My list looks like this:

Post 1.1
Post 1.2
Post 2.1
Post One
Post 1.1
Post 1.2
Post Two
Post 2.1
Post Three
Post Four
