OptStack

WordPress Data Stack Framework — A PHP framework for defining, storing, and managing structured data in WordPress using a unified, extensible stack-based model.

Features

• Data-first, UI-agnostic — Focus on data modeling, not UI
• Native WordPress compatibility — Works with get_option(), get_post_meta(), get_term_meta()
• Unified data model — Same field syntax across Options, Posts, Terms, Users
• Quick field updates — Update single fields with automatic searchable field sync
• Runtime context injection — Use as plugin or Composer library, no conflicts
• Composable & extensible — Interface-driven architecture
• Future-proof — Ready for Headless WordPress and REST workflows
• Modern Admin UI — React + TypeScript + TailwindCSS frontend

Requirements

• PHP 8.1+
• WordPress 6.0+
• Node.js 18+ (for frontend development)

Installation

As a WordPress Plugin

1. Clone or download to wp-content/plugins/optstack/
2. Run composer install in the plugin directory
3. Activate the plugin in WordPress admin

As a Composer Library (in Themes/Plugins)

OptStack can be used as a pure Composer library in your own plugins or themes:

composer require optstack/optstack

Then bootstrap with runtime context injection:

// In your plugin or theme
require_once __DIR__ . '/vendor/autoload.php';

\OptStack\WordPress\Bootstrap::boot([
    'file' => __FILE__,
    'dir' => plugin_dir_path(__FILE__),  // or get_template_directory() for themes
    'url' => plugin_dir_url(__FILE__),   // or get_template_directory_uri() for themes
    'version' => '1.0.0',
]);

Benefits:

• ✅ Multiple plugins/themes can use OptStack simultaneously
• ✅ No conflicts between different hosts
• ✅ Assets load from the correct location automatically

See documents/OPTSTACK_RUNTIME_CONTEXT_INJECTION.md for details.

For Frontend Development

cd wp-content/plugins/optstack/frontend
npm install
npm run build    # Production build

Development Mode (Hot Reload)

For live reloading during frontend development:

1. Add to wp-config.php:

   define('OPTSTACK_DEV_MODE', true);

2. Start the dev server:

   cd wp-content/plugins/optstack/frontend
   npm run dev

3. Open your WordPress admin page - CSS and component changes update instantly!

Quick Start

Define an Options Stack

use OptStack\OptStack;

// Register on init
add_action('optstack_init', function() {
    OptStack::make('site_settings')
        ->forOptions()
        ->label('Site Settings')
        ->define(function ($stack) {
            $stack->field('site_color', [
                'type' => 'text',
                'label' => 'Primary Color',
                'default' => '#000000',
            ]);

            $stack->group('social', function ($group) {
                $group->field('twitter', ['type' => 'text']);
                $group->field('facebook', ['type' => 'text']);
            });
        });
});

// Access data using native WordPress
$settings = get_option('site_settings');
// ['site_color' => '#000000', 'social' => ['twitter' => '...', 'facebook' => '...']]

// Update a single field (with auto-sync for searchable fields)
OptStack::updateField('site_settings', 'site_color', '#FF5733');

Define a Post Type Stack

add_action('optstack_init', function() {
    OptStack::make('product_data')
        ->forPostType('product')
        ->label('Product Data')
        ->define(function ($stack) {
            $stack->group('pricing', function ($group) {
                $group->field('price', ['type' => 'number']);
                $group->field('currency', [
                    'type' => 'select',
                    'options' => ['USD' => 'US Dollar', 'EUR' => 'Euro'],
                ]);
            });
        });
});

// Access via post meta
$product_data = get_post_meta($post_id, 'product_data', true);

Define a Taxonomy Stack

add_action('optstack_init', function() {
    OptStack::make('category_settings')
        ->forTaxonomy('category')
        ->define(function ($stack) {
            $stack->field('icon', ['type' => 'text']);
            $stack->field('color', ['type' => 'text']);
        });
});

Field Types

Type	Description	Options
text	Single-line text input	placeholder
number	Numeric input	min, max, step
textarea	Multi-line text	rows
select	Dropdown select	options
boolean	Toggle/checkbox	—

Groups & Repeatables

$stack->group('features', function ($group) {
    $group->repeatable(1, 10); // min 1, max 10 items

    $group->field('title', ['type' => 'text']);
    $group->field('enabled', ['type' => 'boolean']);
});

// Data structure:
// ['features' => [
//     ['title' => 'Feature A', 'enabled' => true],
//     ['title' => 'Feature B', 'enabled' => false],
// ]]

Conditional Fields

$stack->field('enable_advanced', ['type' => 'boolean']);

$stack->field('advanced_option', [
    'type' => 'text',
    'conditions' => [
        ['field' => 'enable_advanced', 'operator' => '==', 'value' => true]
    ]
]);

REST API

OptStack exposes a REST API for frontend consumption:

• GET /wp-json/optstack/v1/stacks — List all stacks
• GET /wp-json/optstack/v1/stacks/{id} — Get stack schema
• GET /wp-json/optstack/v1/stacks/{id}/data — Get stack data
• POST /wp-json/optstack/v1/stacks/{id}/data — Save stack data

Architecture

┌─────────────────────────────────────────┐
│           Renderers (UI/API)            │  ← React Admin, REST
├─────────────────────────────────────────┤
│         Store Adapters (WP)             │  ← OptionsStore, PostStore
├─────────────────────────────────────────┤
│           Core Framework                │  ← Pure PHP, no WP
└─────────────────────────────────────────┘

• Core — Pure PHP, no WordPress dependencies, fully unit testable
• WordPress — Store adapters and hooks
• Frontend — React + TypeScript admin UI

Development

# Backend
composer install
composer test

# Frontend
cd frontend
npm install
npm run build    # Production build
npm run dev      # Development server (requires OPTSTACK_DEV_MODE)

Frontend Dev Mode

OptStack supports hot module replacement (HMR) for rapid frontend development.

Setup:

1. Enable dev mode in wp-config.php:

   define('OPTSTACK_DEV_MODE', true);
   // Optional: custom port
   // define('OPTSTACK_DEV_SERVER', 'http://localhost:3000');

2. Start Vite dev server:

   cd frontend && npm run dev

3. Refresh your WordPress admin page - changes will update live!

How it works:

• In dev mode, WordPress loads assets from Vite's dev server (localhost:5173)
• CSS changes apply instantly via HMR
• JS/TSX changes trigger a page refresh
• In production mode (default), built assets from frontend/dist/ are used
