Install
This is the repository archive. It installs, but the folder name will carry the branch suffix and updates will not flow.
Install straight from GitHub with WP-CLI:
wp plugin install https://github.com/kostasntamas/carbon-field-ui/archive/refs/heads/main.zipNo built-in updater. New versions won't appear under Dashboard → Updates. Install new releases yourself, or let Git Updater track the repository.
A simple admin interface for creating custom fields with Carbon Fields — no code required. Carbon Fields itself is bundled in vendor/ (no Composer needed to run the plugin).
Usage
- Activate the plugin.
- Go to Field Groups → Add New in the WP admin.
- Give the group a title (used internally, and shown as the meta box title on post/term/user screens).
- Locations tab: add one row per place you want the fields to appear — Post Type (optionally limited to a page template), Taxonomy, User Profile, or a new/existing Options Page. Add several rows to show the same fields in more than one place.
- Fields tab: add one row per field — label, auto-generated or custom meta key, field type, help text, default value, choices (for Select/Radio/Checkbox Set), and whether it's required.
- Publish. The fields appear immediately wherever you targeted them.
- Uncheck Active (under Settings) to hide a group without deleting it.
Reading values in your theme
Use Carbon Fields' own helper functions with the meta key you set on the field:
carbon_get_post_meta( get_the_ID(), 'subtitle' ); carbon_get_term_meta( get_queried_object_id(), 'tagline' ); carbon_get_user_meta( get_current_user_id(), 'phone' ); carbon_get_theme_option( 'company_address' );Supported field types
Text, Textarea, Rich Text, Number, Checkbox, Select, Radio, Checkbox Set, Image, File, Date, Color Picker, Group, Repeater.
- Date renders as a plain HTML5
<input type="date">— no picker library/styling attached. - Group is a fixed set of sub-fields (always exactly one),
- Repeater is the same but repeatable. Both get their own "Sub Fields" tab once selected, with the same field options minus Group/Repeater — nesting is one level deep, by design.
Field_Types::create() in includes/class-field-types.php is the place to add more leaf types later.
Notes
- Carbon Fields is bundled under
vendor/htmlburger/carbon-fields(GPLv2) and booted directly — no Composer install step needed. - Deleting a field group only removes its definition; any data already saved under its meta keys stays in the database.
