It automatically computes product prices based on daily gold and silver rates, metal purity (karat), product weight, and store pricing rules. #### Core Highlights * **Daily Metal Rates**: Set daily 24K Gold and Silver base prices per gram from your admin dashboard. * **Metals & Purities**: Complete catalog management for 24K, 22K, 18K, 14K, Silver, Platinum, and custom formulas or fixed rates. * **Deterministic Pricing**: (Metal Rate * Purity % * Weight) + Base Price + Making Charges + Wastage + Markup + Tax + Shipping. * **Authoritative Price Rounding**: Clean up odd price totals into shopper-friendly figures (None, Nearest 10, 50, 100, or Custom) across cart and checkout. * **Product Whitelists**: Restrict metal selections per product. * **Variable Products**: Set custom weights, metals, and charges per variation. * **Automatic Sale Pricing**: Displays dynamic metal prices as sale prices with strikethrough regular prices. * **100% Private**: Fully self-contained on your server with zero external calls and zero tracking. ## Installation 1. Log in to your WordPress administrator dashboard. 2. Navigate to **Plugins** -> **Add New**. 3. Click **Upload Plugin** and select the `dynamic-metal-price-calculator.zip` package, or search for `Dynamic Metal Price Calculator`. 4. Click **Install Now**, then click **Activate**. 5. Open **Metal Prices** -> **Metal Rates** in your admin menu. 6. Enter current 24K Gold and Silver rates per gram and save. 7. Open any WooCommerce product to assign metal type, weight, and pricing rules. ## FAQ ### How does the pricing calculation work? The pricing engine computes the product price deterministically: 1. Resolves base metal rate (e.g. Gold Rate * Purity % / 100). 2. Multiplies rate by item weight in grams. 3. Adds fixed base price (e.g. stones, diamonds, packaging). 4. Adds percentage making/labour charge. 5. Adds percentage wastage allowance. 6. Adds percentage retail markup. 7. Adds percentage GST / sales tax. 8. Adds flat shipping fees. 9. Applies authoritative price rounding (Nearest 10, 50, 100, or Custom increment). ### What is the difference between Active and Show in Dropdown? * **Active (On/Off)**: Master switch. Inactive metals cannot be used in calculations for new items. * **Show in Dropdown (On/Off)**: Visibility switch. Turning this OFF hides the metal from new product selectors while allowing existing products using this metal to continue calculating prices accurately. ### How do I restrict available metals for a specific product? On the product edit screen, use the **Allowed Metals for this Product** checklist. Leaving all unchecked allows all globally active metals. Checking one or more metals restricts that product and its variations to only the checked options. ### How does Price Rounding work? Price rounding is applied once to the final calculated price using standard half- up arithmetic: * **None**: Exact calculated price. * **Nearest 10**: e.g. 2,254- > 2,250; 2,256 -> 2,260. * **Nearest 50**: e.g. 2,201 -> 2,200; 2,249 -> 2,250; 2,276 -> 2,300. * **Nearest 100**: e.g. 2,249 -> 2,200; 2,250 -> 2,300. * **Custom Increment**: Any numeric increment (e.g. 25, 5, or 0.50). Rounding is authoritative and carries through into the cart, checkout, payment gateway, and placed orders. ### How do I configure Variable Products? 1. In a Variable Product, go to the **Variations** tab and expand a variation. 2. Check the box: **« Use Dynamic Metal Price Calculator for this variation »**. 3. Select the metal type and enter the variation’s weight in grams. 4. Leave charge fields blank to inherit parent product or global defaults. 5. Save variations. ### Can I use custom formulas or fixed rates? Yes. In the Metals & Purities Manager, choose the **Custom** group: * Enter a mathematical formula referencing variables `gold_rate` or `silver_rate` with `+`, `-`, `*`, `/`,`(`,`)`( e.g. `gold_rate * 1.25`). * Or simply enter a fixed rate (e.g. `500`) without any formula. All formulas are parsed using a safe Reverse Polish Notation (RPN) stack with zero arbitrary code execution. ### What if a metal option does not appear in the product dropdown? 1. Verify that the metal is **Active** and **Show in Dropdown** is enabled in the Metals & Purities Manager. 2. Check if the product has an **Allowed Metals** whitelist that excludes this metal. 3. Save settings and refresh the product editor page. ### Does this plugin fetch live rates from an external API? No. Store owners enter manual daily rates in **Metal Prices** -> **Metal Rates**. This gives merchants absolute control over pricing without relying on third-party API keys or rate limits. ### Can I hide certain charge details from shoppers on the product page? Yes. In **Metal Prices** -> **Frontend Display Controls**, toggle individual components on or off. Hidden components remain active in the background calculation. ### Does this plugin send data outside my server? No. Dynamic Metal Price Calculator is 100% self-contained. It makes zero external HTTP requests, contains zero tracking, and does not collect or transmit store or customer data. ### Is the plugin compatible with High-Performance Order Storage (HPOS)? Yes. The plugin declares official compatibility with WooCommerce HPOS (`custom_order_tables`) and WooCommerce Cart & Checkout Blocks. ## Avis Il n’y a aucun avis pour cette extension. ## Contributeurs/contributrices & développeurs/développeuses « Dynamic Metal Price Calculator » est un logiciel libre.
