I have a Gallery field inside flexible content.
I also have a Select field on media attachments called ‘data_category’. This field allows multiple selections.
I am trying to display the values from the ‘data_category’ attachment field along with each image in the gallery.
<?php
$images = get_sub_field('gallery');
if( $images ): ?>
<div class="grid">
<?php foreach( $images as $image ): ?>
<?php $data_category = get_field('data_category', $image['ID']);?>
<a href="<?php echo $image['url']; ?>" class="element-item category_name" data-category="category_name">
<img src="<?php echo $image['url']; ?>" alt="<?php echo $image['alt']; ?>" title="<?php echo $image['title']; ?>" />
<?php echo $data_category;?>
</a>
<?php endforeach; ?>
</div>
<?php endif; ?>
When the code is rendered, instead of the data_category being displayed, it just says ‘Array’. This happens when the return format is set to Label or Value. When I set the return format to Both, nothing shows.
Does anyone know what I need to change to get it working?
Many thanks.
