Hey there!
First off, can’t stress how much I love ACF, its totally changed the way I build things! I’m just stuck on a little thing!
I’m kinda stuck trying to get data out of an Gallery field, thats nested in a couple of queries. However, I can get normal ACF field – its just the gallery one that comes up blank, so I’m not sure why.
<?php
$args = array ( 'post_type' => 'school-category');
$loop = new WP_Query( $args );
while ( $loop->have_posts() ) : $loop->the_post();
?>
<div>
<?php
/* films is a realtionship ACF field */
$films = get_field('films');
if( $films ): ?>
<div class="image_data">
<?php foreach( $films as $post): ?>
<?php setup_postdata($post); ?>
<?php if ( get_field('running_time') ) :
the_field('running_time');
endif; ?>
<?php if ( get_field('images') ) :
the_field('images');
endif; ?>
<?php endforeach; ?>
</div>
<?php wp_reset_postdata(); ?>
<?php endif; ?>
</div>
<?php endwhile; ?>
So the running_time field gives me a result, but not the images field.
Anyone have any ideas why?
Thanks!
Are you trying to create a gallery by using the code the_field('images');
?
This is not possible.
The gallery field will return an array of images – each being an array containing data associated to that image.
You need to follow the documentation to understand how to loop through the images and render a gallery
Thanks

Hey Elliot,
Sorry, I simplified that to make it easy to understand (but prob made it more confusing :B ). Here’s my full code:
<?php
$args = array ( 'post_type' => 'school-category');
$loop = new WP_Query( $args );
while ( $loop->have_posts() ) : $loop->the_post();
?>
<div>
<?php
/* films is a realtionship ACF field */
$films = get_field('films');
if( $films ): ?>
<div class="image_data">
<?php foreach( $films as $post): ?>
<?php setup_postdata($post); ?>
<?php if ( get_field('running_time') ) :
the_field('running_time');
endif; ?>
<?php if ( get_field('images') ) :
$images = get_field('images'); ?>
<img src="<?php echo $images[0]['url']; ?>" alt="<?php the_title(); ?>">
<?php endif; ?>
<?php endforeach; ?>
</div>
<?php wp_reset_postdata(); ?>
<?php endif; ?>
</div>
<?php endwhile; ?>
The issue is that the if (get_fields(‘images’)) returns a false, where as all over the rest of the site it returns true. I dumped all the post’s custom fields and could see that images was an empty array, where all the ACF fields returned their values.
Any ideas? Thanks Elliot!
Can you find the film ID, edit the film and make sure the gallery field contains a value?
