Description

Fieldom gives agencies and developers a community-governed, feature-rich custom fields plugin for WordPress.

Every feature is built and maintained in the open. No freemium gates, no SaaS backend, no phone-home. Just a solid custom-fields plugin that runs entirely inside WordPress.

Key Features

  • 26 field types — text, textarea, number, select, checkbox, radio, true/false, date picker, time picker, color picker, URL, email, password, file, image, gallery, post object, taxonomy, user, link, WYSIWYG, message, tab, accordion, Repeater, and Flexible Content.
  • Native Repeater field — supports drag-to-reorder rows, configurable sub-fields, and min/max row limits.
  • Flexible Content field — multiple layouts each with their own sub-fields, drag-to-reorder blocks.
  • Options Pages — register custom admin pages and store global settings outside of post meta.
  • JSON import / export — export field groups as JSON and import them on any site. Field types, choices, location rules, Repeater sub-fields, and Flexible Content layouts are all mapped automatically.
  • Standard postmeta storage — values are stored in standard wp_postmeta using established key conventions, compatible with any plugin that reads WordPress post meta.
  • Template helpers — fieldforge_get(), fieldforge_the(), fieldforge_have_rows(), fieldforge_the_row(), fieldforge_sub_field(), fieldforge_the_sub_field(), fieldforge_update_field(), fieldforge_get_option(), fieldforge_update_option().
  • Location rules — show field groups by post type, post status, user role, page parent, or page template. OR groups and AND rules.
  • Conditional logic — show or hide individual fields based on the values of other fields.
  • REST API — field values exposed via the WordPress REST API with location-rule filtering.
  • Local JSON sync — field groups saved as JSON files alongside your theme for version control.
  • 100% GPL, no SaaS — runs entirely inside WordPress. No external services.

Basic Usage

  1. Go to Fieldom Add New to create a field group.
  2. Click + Add Field, choose a field type, give it a name and label.
  3. Set a location rule (e.g. “Post Type is equal to Post”).
  4. Publish the field group.
  5. Edit any matching post — your fields appear as a meta box.

In your theme templates:

<?php echo esc_html( fieldforge_get( 'subtitle' ) ); ?>

Or simply:

<?php fieldforge_the( 'subtitle' ); ?>

Repeater Usage

<?php while ( fieldforge_have_rows( 'team_members' ) ) : fieldforge_the_row(); ?>
    <h3><?php fieldforge_the_sub_field( 'name' ); ?></h3>
    <p><?php fieldforge_the_sub_field( 'role' ); ?></p>
<?php endwhile; ?>

JSON Import

Go to Fieldom Import / Export, paste your field group JSON, and click Import. All supported field types and location rules are mapped automatically.

See docs/json-import.md in the plugin folder for the full import guide.

Roadmap

  • v0.2 — Gutenberg / block editor field meta boxes
  • v0.3 — Clone field
  • v0.4 — Improved conditional logic UI builder

FAQ

What field types and features are included?

Fieldom includes 26 field types (text, textarea, number, email, URL, password, select, checkbox, radio, true/false, date picker, time picker, color picker, image, file, gallery, post object, taxonomy, user, link, WYSIWYG, message, tab, accordion, Repeater, and Flexible Content), plus Options Pages, conditional logic, a REST API, a JSON importer, and local JSON sync. The Clone field and Gutenberg block fields are on the roadmap.

Can I import existing field group configurations?

Yes — go to Fieldom Import / Export and paste a field group JSON export. Fieldom maps all supported field types, choices, location rules, sub-fields, and Flexible Content layouts automatically.

Is it safe to use on a production site?

v0.1 is an early but stable release. The core save/load path is covered by a PHPUnit test suite running on PHP 7.4 through 8.3. We recommend testing on a staging site before deploying to production, and watching the GitHub releases for patch updates.

How do I display field values in my theme templates?

Use fieldforge_get( 'field_name' ) to return a value, or fieldforge_the( 'field_name' ) to echo it safely escaped. For Repeater fields, use the fieldforge_have_rows() / fieldforge_the_row() / fieldforge_sub_field() loop helpers.

Does Fieldom conflict with other custom field plugins?

Fieldom registers its own function names, CPT slugs, and meta keys and does not interfere with other custom field plugins. You can run multiple custom field plugins simultaneously.
