English-first WooCommerce back-office with worldwide language support, RTL/LTR layouts, and branded PDF invoices.

== Description ==

ZERTI is a full-screen WooCommerce administration panel inside WordPress `wp-admin`. It gives store operators one place to manage orders, inventory, customers, finance, and reports—without replacing the public storefront.

The UI is **English by default** and ships with translation files for multiple admin languages. Regional settings control UI language, text direction, calendar system, and digit formatting so merchants worldwide can work in a familiar locale.

**Main areas**

* **Home** — sales dashboard, Chart.js charts, cached WooCommerce aggregates
* **Orders** — AG Grid list, filters, order detail, invoice view, status updates, print, PDF downloads
* **Inventory** — products, editor (Quill), categories, tags, brands, attributes, attribute groups, import/export, reviews
* **Finance** — payments, coupons, sales report
* **Reports** — sales report (free), standard reports and BI analytics (Pro)
* **Customer affairs** — customers, product reviews, comments
* **Bulk Action** — bulk price, stock, and delete tools (Pro)
* **Settings** — store identity, logo, invoices, regional options, visual themes, license

**Internationalization**

* Admin UI languages: English, Persian, Arabic, French, Spanish, Turkish, Dutch, Hindi, Thai, Chinese (bundled `.mo` files in `languages/`)
* Follow WordPress site language or pick a dedicated ZERTI UI language in Settings
* Automatic LTR/RTL layout from locale
* Calendars: Gregorian, Jalali (Persian), Hijri (Arabic)
* Digit formats: Western, Persian, Arabic, Devanagari, Thai (automatic or manual)

**PDFs & printing**

Server-generated PDFs (invoice, postal label, warehouse sheet) via mPDF and Dompdf. Browser print templates are also available.

**Themes & appearance**

* Dark / light mode toggle in the sidebar
* Visual themes: Zerti (default), customizable rabbitMP, and Demerzel (cursor.com-inspired)
* Bootstrap-based responsive admin shell with AG Grid data tables

**Other**

* Global search across orders, customers, and products
* HPOS-compatible order queries
* REST API (`zerti/v1`) and AJAX for grids and actions

**Free vs Pro**

The free plugin covers daily shop, inventory, finance, and sales-report work. [ZERTI Pro](https://zerti.shop) (optional license) unlocks list/Excel exports, bulk actions, standard reports, BI reports with Excel export, and order creation from the panel.

**External services**

This plugin may contact external services only in the cases below. Core store operations (orders, inventory, reports) run on your server and do not require outbound connectivity.

* **ZERTI Pro license server** (`https://license.zerti.shop`) — Used when you enter or validate a Pro license key. Sends your license key, site URL (domain), plugin version, WordPress version, and PHP version. No customer orders or payment data are transmitted. [Terms of use](https://zerti.shop/terms/), [privacy policy](https://zerti.shop/privacy-policy/).

* **Gravatar** (`https://gravatar.com`) — Used on the customer detail screen to display the customer avatar via WordPress `get_avatar_url()`. Sends an MD5 hash of the customer email address when that view is opened. [Automattic terms](https://wordpress.com/tos/), [privacy policy](https://automattic.com/privacy/).

* **Google Maps** (`https://www.google.com/maps`) — Optional. When “Show customer location on Google Maps” is enabled under Settings → Postal label PDF, order geolocation coordinates (latitude and longitude, when available from the order) are included in a link to Google Maps on the order detail view and postal PDF. The browser or PDF reader opens that link; ZERTI does not send order data to Google except through that user-initiated URL.

== Installation ==

1. Upload the plugin folder to `/wp-content/plugins/` or install via the WordPress Plugins screen.
2. Ensure **WooCommerce** is installed and active.
3. If `vendor/` is not included, run `composer install --no-dev --optimize-autoloader` on PHP 7.4+.
4. Activate the plugin through the **Plugins** menu.
5. Open **ZERTI** from the admin menu and complete **Settings** (identity, regional language, logo, invoices).

**Requirements**

* WordPress 6.0+
* WooCommerce (active)
* PHP 7.4+ with `mysqli`, `mbstring`, `json`, `dom`, `gd`, and `zlib`
* Writable `wp-content/uploads/` (PDF temp files)

== Frequently Asked Questions ==

= Does ZERTI replace WooCommerce? =

No. ZERTI is an alternative admin UI. WooCommerce remains required for cart, checkout, and storefront behavior.

= Which language does ZERTI use? =

English is the source language. Choose **ZERTI UI language** under Settings → Regional Settings, or leave it on **Site default** to follow WordPress. Drop additional `zerti-{locale}.mo` files into the plugin `languages/` folder to extend translations.

= Does ZERTI support RTL languages? =

Yes. Arabic and Persian (and other RTL locales) switch the admin panel to RTL automatically, including Bootstrap RTL styles when needed.

= Is an internet connection required? =

Core features work without ongoing connectivity. Pro license activation and periodic validation require outbound HTTPS to `https://license.zerti.shop`.

= Which PDF engine is used? =

Invoices and related documents are generated on the server with mPDF and/or Dompdf (bundled in `vendor/`).

= Is HPOS supported? =

Yes. ZERTI supports WooCommerce High-Performance Order Storage and legacy order storage.
