custom-field

Two near-identical custom field types – one works, the other doesn’t . What can cause this?

I found an older post showing what I was missing from my code, so it seems like I didn’t do a good enough search to begin with.

Woocommerce – How to populate custom select field with stored values on checkout page?

Advanced Custom Fields: Sorting custom columns with custom fields sorts only by date

It appeared it was due to the fact that WordPress doesn’t understand that you need to order by certain post meta unless you specify it. So in my case adding this fixed the sorting issue: add_action( ‘pre_get_posts’, ‘custom_orderby’ ); function custom_orderby( $query ) { if( ! is_admin() ) return; $orderby = $query->get( ‘orderby’); if( ‘featured’ … Read more

How can I show custom fields in the loop only to specific user roles?

You can use current_user_can() and is_user_logged_in() to validate current user: <?php if ( is_user_logged_in() && current_user_can(‘role’) ) : ?> <span style=”font-size:16px”> <strong>Currently reading:</strong> <?php the_field(‘book_name’); ?> (<?php the_field(‘book_year’); ?>)<br/> <strong>Currently seeing:</strong> <?php the_field(‘movie_name’); ?>”><br/> </span> <?php endif; ?> Make sure to change role to your preference and take a look at Codex for more info.
