I am trying to use the relationship field outside of the main loop. See relationship code below:
<?php
global $post; // Needed for use inside a widget
$posts = get_field('related_posts');
if($posts):
$i = 1; ?>
<li class="parent"><a href="#">Related Articles</a>
<ul class="related-posts">
<?php foreach($posts as $post): // variable must be called $post (IMPORTANT) ?>
<?php setup_postdata($post); ?>
<li class="related_post-<?php echo $i; ?>">
<div class="col-md-4">
<?php if(has_post_thumbnail()) { ?>
<a href="<?php the_permalink(); ?>"><?php the_post_thumbnail(); ?></a>
<?php }; ?>
</div>
<div class="col-md-8">
<h4 class="post-title"><a href="<?php the_permalink(); ?>"><?php the_title(); ?></a></h4>
<?php custom_excerpt(75); ?>
</div>
</li>
<?php $i++; endforeach; ?>
</ul>
</li>
<?php wp_reset_postdata();
endif; ?>
I have to set the global $post at the top of this to make it work outside of the loop. For some reason if I setup another relationship field underneath this one it does not work. Can someone explain to me why this is and how to make it so I can have multiple relationship fields working outside of the main loop.
Many thanks
Not 100% sure but, being the get_field() is a global function you MIGHT have to specifically target the post your are getting the related fields from…
Maybe doing something like the following would work
global $post;
$post_id = $post->ID;
$posts = get_field( "related_posts", $post->ID );
I’m assuming your above code displays the relationship data properly. Please post the code that is NOT working.
The relationship field is pulling in the data from the page that I am on, which is correct. My issue comes if I duplicate the code above and paste it below it (to have 2 instances of the same code), I would assume that the same data would appear below, but that 2nd instance does not appear.
