Init User Engine - A gamified, frontend-first user system for WordPress

Why Init User Engine?

Most "membership" or "points" plugins for WordPress are heavy, admin-ajax-based, and hard to theme. Init User Engine takes the opposite approach: everything dynamic - avatar, dashboard, check-in, inbox, VIP purchase - is rendered client-side in pure Vanilla JS and talks to a clean REST API. Drop in one shortcode and you get a full gamified account system on top of native WordPress users.

It's the core user system behind the Init Plugin Suite - the same minimalist, performance-first philosophy as Init Live Search.

Features at a Glance

Gamified Progression

• EXP & Level system with fully hookable progression logic
• Coin & Cash wallet with transaction logs (dedicated DB tables, not user meta)
• Daily check-in with streak milestones and an online-time bonus timer
• Daily task list, extensible via filter

Frontend-First UX

• One shortcode: [init_user_engine] - avatar button + full modal dashboard
• Avatar system with upload, live preview, and revert-to-default support
• Login/Register modals for logged-out visitors, with custom redirect URLs
• Pure Vanilla JS - no jQuery, no server-rendered admin-ajax round trips

Monetization & Retention

• VIP membership, purchased with in-site Coin, with configurable duration tiers (including lifetime)
• VIP bonus system - extra Coin/EXP percentage for VIP members
• Redeem Code / Gift Code module - generate single-use or bulk codes, redeem for rewards
• Referral module with cookie-based signup tracking and rewards for both sides

Communication

• Built-in inbox with pagination, category filters (System, Rewards, Activity...), read/claim/delete
• Admin panel to send notifications to selected users or the whole member base, with priority and expiration

Built for Developers

• REST API for every feature - register, check-in, claim reward, inbox, VIP purchase, redeem code, profile, and more
• Deep set of action/filter hooks: modify EXP curves, VIP prices, referral rewards, theme colors, VIP body classes, and more
• Transaction and EXP logs stored in dedicated tables with wp_cache support and true paginated queries - built to scale, not just to demo

Developer Hooks

Init User Engine ships with a wide surface of filters and actions so you're never stuck waiting on a plugin update to customize behavior:

// Change how much EXP is required per level
add_filter( 'init_plugin_suite_user_engine_exp_required', function( $required, $level ) {
    return $level * 100;
}, 10, 2 );

// React to a level-up
add_action( 'init_plugin_suite_user_engine_level_up', function( $user_id, $new_level ) {
    // send a custom notification, unlock content, etc.
}, 10, 2 );

Other notable hooks include filters for VIP pricing, referral rewards, check-in milestones, daily tasks, theme colors, and VIP-related body classes - plus actions for EXP/Coin changes, referral completion, and admin notifications.

Where Data Lives

• user_meta - EXP, level, Coin, Cash, VIP, referral
• Dedicated DB tables - transaction log and EXP log (migrated off user meta for scalability as of v1.5.0)
• wp_init_user_engine_inbox - inbox messages

Installation

Install via WordPress.org or:

git clone https://github.com/brokensmile2103/init-user-engine.git

Then:

• Activate the plugin
• Drop [init_user_engine] into any page, post, or template
• Configure theme color, currency labels, and reward values under Settings → Init User Engine

That's it - modals and logic load automatically.
