MilliBase

Declarative WordPress settings framework. Define your settings page in PHP arrays — tabs, sections, fields, validation — and get a React-powered admin UI automatically.

Requirements

Requirement	Version
PHP	>= 7.4
WordPress	>= 6.0

Quick Start

⚠ Plugin authors: prefix MilliBase before shipping. If you bundle MilliBase inside a distributed plugin, you must vendor-prefix it with Strauss or php-scoper. Two plugins shipping the unprefixed MilliBase\ namespace will collide at runtime — only one copy will load, and the other plugin runs against a version it wasn't tested with. See Namespace Prefixing for setup and the rationale behind MilliBase's cross-prefix-tolerant typing.

composer require millipress/millibase

use MilliBase\Manager;

$manager = new Manager(
    slug: 'my-plugin',
    config: fn() => [
        'page_title' => __( 'My Plugin', 'my-plugin' ),
        'menu_title' => __( 'My Plugin', 'my-plugin' ),
        'header'     => [ 'title' => __( 'My Plugin Settings', 'my-plugin' ) ],
        'tabs'       => [
            [
                'name'     => 'general',
                'title'    => __( 'General', 'my-plugin' ),
                'sections' => [
                    [
                        'id'     => 'main',
                        'title'  => __( 'Main Settings', 'my-plugin' ),
                        'fields' => [
                            [
                                'key'     => 'general.enabled',
                                'type'    => 'toggle',
                                'label'   => __( 'Enable Feature', 'my-plugin' ),
                                'default' => true,
                            ],
                        ],
                    ],
                ],
            ],
        ],
    ],
);

// Programmatic access:
$manager->settings()->get('general.enabled'); // true

Features

• Declarative schema — define tabs, sections, and fields in PHP arrays
• React admin UI — auto-generated from the schema using @wordpress/components
• 9 built-in field types — text, number, password, toggle, select, unit, token-list, color, code
• Custom extensibility — register custom field types and custom tab components from JS
• Conditional display — show/hide fields based on other settings values
• Settings priority — constants > config file > database > defaults
• Encryption — automatic sodium encryption for sensitive fields (keys prefixed with enc_)
• Config file sync — write settings to PHP files for pre-WordPress access (blog-aware per-operation; _network-<id>.php mirror for network-mode)
• Network mode — 'network' => true routes storage to wp_sitemeta and the admin page to Network Admin
• Migrations — declarative name@version one-shot runner with per-scope state (site / network)
• Backup & restore — transient-based backup with 12-hour expiry
• Import / export — settings serialization with encryption handling
• Tab overrides — add-on plugins can extend or replace tabs and sections via filters
• REST API — namespaced GET/POST /{namespace}/v1/settings + custom action endpoints
• WP-CLI — auto-registered wp <slug> config commands; two Managers sharing a cli.slug auto-merge into one tree
