Thanks @jonathan
I think the issue is I was calling get_field with the field key instead of the field name. It seems that ACF returns an empty object for this if there is no value. When I switched to the field name, I stopped getting errors.
Was just a typo!
`$member[‘location_details’] = array(‘address’ => $formatted_address, ‘lat’ => $centre_lat, ‘lng’ => $centre_long, ‘zoom’ => 14);
I had this too. I was adding fields to categories but they weren’t showing up. Reverted to 5.1.9 and they are back. That was a waste of 3 hours.
I know this post is from a while ago now but I had a similar issue. I solved it like so:
<?php if (have_rows('flexible_content')) :
while (have_rows('flexible_content')) : the_row();
if (get_row_layout() == 'images_row'):
$header = get_sub_field('heading'); ?>
<div class="block-text-centered">
<h2 class="upper grey"><?php echo $header;?></h2>
</div>
<?php $rows = get_sub_field('images');
if ($rows) : ?>
<div class="pure-g">
<?php foreach ($rows as $row) : $img = wp_get_attachment_image_src($row['ID'], 'thumbnail'); ?>
<div class="pure-u-1-5 client-logo">
<img src="<?php echo $img[0]; ?>" alt="<?php echo $row['alt']; ?>">
</div>
<?php endforeach; ?>
</div>
<?php endif;
endif;
endwhile;
else :
endif; ?>
