Hi there,
I might have a related issue. Upon activation of the latest Options add-on (with ACF v4.3.5 & WordPress v3.8.1) I get the same error:
Strict Standards: Only variables should be passed by reference in /Users/bramwillemse/Dropbox/Sites/gsc/wp-content/plugins/acf-options-page/acf-remote-update.php on line 27
Next to that I’m not able to register a page with this code in functions.php:
if( function_exists('acf_add_options_sub_page') )
{
acf_add_options_sub_page(array(
'title' => 'Contact',
'parent' => 'options-general.php',
'capability' => 'manage_options'
));
}
Also other options page functions do not have any effect. And this happens when trying to add a group to the options page:

Any help would be much appreciated!
Good to know what the problem is here. But I don’t understand why it suddenly started breaking my websites.
It’s an important realization that testing every update locally and on a staging environment is really the way to go..
Anyways, I hope v5 will come soon!
Your remark got me thinking though, Elliot. And now I found the simple solution: rename the post object! The solution:
<?php // If selection is made, load selection of customers
$customers = get_sub_field('customers-select');
if( $customers ): ?>
<?php foreach( $customers as $customer): // variable must be called $post (IMPORTANT) ?>
<?php setup_postdata($customer); ?>
<?php $post_id = $customer->ID; ?>
<?php $thumbid = get_post_thumbnail_id($post_id); ?>
<?php $img = wp_get_attachment_image_src( $thumbid, 'medium' ); ?>
<?php $logo = $img[0]; ?>
<?php $customer_url = get_field('customer-url', $post_id); ?>
<li class="l-fifth customer">
<a href="<?php echo $customer_url ?>" role="img" alt="<?php the_title(); ?>" style="background-image:url(<?php echo $logo ?>);"></a>
</li>
<?php endforeach; ?>
<?php wp_reset_postdata(); // IMPORTANT - reset the $post object so the rest of the page works correctly ?>
<?php endif;?>
Thanks & sorry for the waste of time, I should’ve known since I already used this method quite a lot of times.
Hi Elliot,
Thanks for your quick reply. But I’m quite sure that would’nt work.
The thing is, all this code is loaded on a page. The customer post objects are loaded in the foreach loop created with the relationship field. So the $post->ID variable should come out of the postdata within the foreach loop. If I would place it outside, the $post->ID from the page it’s all being load on would be used instead of the customer post objects.
The weird thing is, the customer post objects $post->ID works for the post thumbnail:
<?php $thumbid = get_post_thumbnail_id($post->ID); ?>
But it doesn’t work when I call the custom field by that same $post->ID in the same foreach loop.
<?php $customer_url = 'href="' . get_field('customer-url', $post->ID) . '"'; ?>
I just found this post on the forum (I searched before already 😉 ):
http://support.advancedcustomfields.com/forums/topic/displaying-items-within-a-cpt-as-choices-in-repeater-for-another/
It might be related to my problem. Do I understand correctly my only solution is to maybe use the ‘Dynamically populate a select field’s choices’ solution? 🙁
