Codeideal Open Fields lets you add custom fields to posts, pages, custom post types, taxonomies, and users. The admin interface is built with React and TypeScript — fast, responsive, and intuitive.
All features are free. No premium tier. No locked functionality.
Quick Start
get_field( 'my_field' ) — retrieve any field value.
the_field( 'my_field' ) — echo a field value directly.
Template Examples
Simple field:
<?php echo esc_html( get_field( 'subtitle' ) ); ?>
Repeater loop:
<?php while ( have_rows( 'team_members' ) ) : the_row(); ?>
<h3><?php the_sub_field( 'name' ); ?></h3>
<p><?php the_sub_field( 'role' ); ?></p>
<?php endwhile; ?>
User field (with prefix):
<?php echo esc_html( get_field( 'company', 'user_' . $user_id ) ); ?>

ACF-Compatible API
If you know ACF, you already know Open Fields. The template API uses the same function names:
get_field()/the_field()get_fields()/update_field()/delete_field()have_rows()/the_row()/get_sub_field()/the_sub_field()get_row()/get_rows()/reset_rows()/get_row_index()get_field_object()/get_sub_field_object()
When ACF is also active, these wrappers are not loaded — no conflicts. Both plugins store data as standard WordPress meta, so they can coexist.
Every function also has a prefixed version (e.g. cofld_get_field()) that is always available regardless of other plugins.
