Designed for performance and flexibility, it handles everything from simple currency exchanges to complex, non-linear physical unit conversions (like Temperature). Whether you run a travel blog, or a technical documentation hub, this plugin ensures your visitors see accurate conversions in a format that fits your design. 🚀 My Ambition: Premium Features for Free With this initial release, my goal is to set a new standard for what a free plugin can offer. I believe advanced tools shouldn’t be locked behind a paywall. That is why Smart Convert includes enterprise- grade features usually found only in paid versions: a Custom Unit Builder, a Template Engine, Import/Export capabilities, and Automatic Geolocation—all completely free. ### 🌟 Key Features **💰 Advanced Currency Engine** * **Rates:** Supports 153 global currencies + cryptocurrencies( BTC, ETH, etc.). * **Smart Geo-Location:** Automatically detects visitor IP to display their local currency (powered by ipinfo.io). * **„Spread“ & Fees:** Add a percentage markup (e.g., 2%) to exchange rates to simulate bank fees or retail pricing. * ** Smart Rounding:** Intelligently adjusts decimals (e.g., 0 decimals for JPY, 6 decimals for BTC). **📏 Comprehensive Unit Converter** * **105+ Built-in Units:** Covers 14 categories including Length, Mass, Volume, Temperature, Pressure, Energy, Speed, and Data. *** Bi-Directional Custom Units:** Creating a unit like „Box“ (e.g., 1 Box = 12 Items). The plugin automatically generates the reverse conversion logic for you. * **Complex Math:** Handles non-linear conversions (like Fahrenheit to Celsius) with precision offset calculations. **🎨 Visual & Editor Integration** * **Native Gutenberg Block:** Visually configure conversions (Amount, From, To, Decimals) with a live backend preview. * **Inline Toolbar Tool:** Select any text in your post and convert it instantly using the rich text toolbar button. * **Interactive Tooltips:** Solves the common „overflow: hidden“ clipping issue using a smart portal strategy to display rates on hover. *** Template System:** Design your output using placeholders like `{FROM}`, `{TO}`, `{ RATE}`, and `{DATE}`. **⚙️ Performance & Workflow** * **Zero Database Bloat:** Uses robust Object Caching and Transients. * **Import/Export:** Transfer your custom templates and custom units between sites via JSON. * **Privacy First:** External connections are disabled by default until explicit consent is given via the Onboarding Wizard. ### 🌍 Internationalization & Translations Smart Convert – Currency & Unit Conversion is fully localized and ready for global audiences. The plugin is translated into the following languages: * English * Spanish (Español) * Japanese (日本語) * German (Deutsch) * French (Français) * Russian (Русский) * Brazilian Portuguese (Português do Brasil) * Italian (Italiano) * Czech (Čeština) * Dutch (Nederlands) * Turkish (Türkçe) * Polish (Polski) * Indonesian (Bahasa Indonesia) ### ⚖️ Privacy & External Services Disclosure To provide up-to-date exchange rates and geolocation features, this plugin may connect to selected third-party services. **No data is sent without your explicit consent via the settings page.** 1. **Currency & Unit Data (Google Sheets via Proxy)** 2. * **Service:** Downloads conversion rates from public datasets. * **Mechanism:** Requests are routed through a static redirect wrapper on `petrnovak. cz` to ensure link stability. * **Data Sent:** Your server’s IP address (standard HTTP request). No visitor data is sent. * **Policy:** [Google Privacy Policy](https://policies.google.com/privacy) * **Proxy Policy:** [PetrNovak.cz Privacy Policy](https://petrnovak.cz/plugins/smart-convert-currency-unit-conversion/privacy-policy.php) 3. **Geolocation (IPinfo.io)** 4. * **Service:** Used **only** if „Auto-detect currency from IP“ is enabled in settings. * **Mechanism:** Sends the visitor’s IP address to IPinfo.io to determine their country code (e.g., „US“). * **Data Sent:** Visitor IP Address. * **Policy:** [IPinfo Privacy Policy](https://ipinfo.io/privacy) ## Снимци екрана [⌊General Settings: Configure update intervals, number formatting, and global exchange rate markups.⌉⌊General Settings: Configure update intervals, number formatting, and global exchange rate markups.⌉[ **General Settings:** Configure update intervals, number formatting, and global exchange rate markups.

Upload the plugin files to the `/wp-content/plugins/smart-convert-currency-unit- conversion` directory, or install the plugin through the WordPress plugins screen. 2. Activate the plugin through the ‘Plugins’ screen in WordPress. 3. **Onboarding:** You will be redirected to a setup wizard. Click „Connect & Initialize“ to download the latest rates and unit definitions. 4. Navigate to **Settings Smart Convert – Currency & Unit Conversion** to configure your default currency and display preferences. ## ЧПП ### Can I add my own units (e.g., „Pallets“ to „Kilograms“)? Yes! Go to the **Units** tab and scroll to „Add Custom Unit“. You can define a name, symbol, and conversion factor. The plugin handles the math for both directions automatically. ### How does the Gutenberg Inline Tool work? Highlight any number in your text editor (e.g., „100“), click the „Money/Convert“ icon in the toolbar, and a popup will appear letting you choose the target currency or unit. ### Does this plugin slow down my site? No. Exchange rates are cached in your database (transients) and updated only once daily via WP-Cron. The frontend shortcode uses these cached values, so no external API calls happen when a visitor loads your page. ### Can I use this for Cryptocurrencies? Yes. The plugin supports major crypto assets like Bitcoin (BTC) and Ethereum (ETH). It also includes logic to handle high-precision decimals (up to 6 places) for small crypto amounts. ### What are the Shortcode Macros/Placeholders? When creating a custom output template, you can use: * `{FROM}` – The source amount with symbol (e.g., $10) * `{TO}` – The converted amount with symbol (e.g., €8.50)*`{ RATE}` – The exchange rate used (e.g., 0.85) * `{DATE}` – The date the rate was last updated * `{RATE_INFO}` – A formatted string showing rate + spread details ( ideal for tooltips) ## Прегледи Нема рецензија за овај додатак. ## Сарадници и градитељи „Smart Convert – Currency & Unit Conversion“ је софтвер отвореног кода.
