From the developer
shayancode's own description of Codeideal Open Fields, lightly tidied.
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.
