About this plugin
This plugin is designed for stores that sell by filling containers with a chosen combination of goods — for example nuts and dried fruits packed into pre-ordered 1 kg, 2 kg or 5 kg boxes.
g. a 100 g pistachio pack, a 200 g almond pack). The total weight must exactly match the pack capacity — the Add to Cart button stays disabled until the pack is perfectly full.

Usage
Step 1: create the weight bundles
For each item (pistachios, almonds, …) create a WooCommerce product:
- Recommended — variable product: e.g. “Pistachios” with a “Weight” attribute and 100 g / 200 g / 500 g variations. Give each variation a price and a weight (the standard WooCommerce weight field) and, with stock management enabled, a stock quantity (e.g. 100 units of the 100 g bundle).
- Simple product: each bundle is a standalone product with a price, weight and stock.
Important: bundle weights must be entered in the standard WooCommerce weight field; the plugin converts them to grams based on the store weight unit (WooCommerce → Settings → Shipping → Weight unit). 1.
g. “Nuts”).
Step 2: create the pack
- Go to Products → Add New.
- In the Product data box set the type to Weight-Based Pack.
- In the Pack Settings tab:
- Pack capacity (grams): e.g. 1000 for a 1 kg box
- Box cost (optional): fixed packaging amount
- Allowed items category: the category from step 1
- Excluded IDs (optional)
- Publish.
Repeat with capacities 2000 and 5000 for the 2 kg and 5 kg boxes.
Step 3: the customer experience
- The customer opens a pack from your shop (the “Build pack” button).
- Using the + / − buttons they choose how many of each bundle to include; the weight progress bar and live price update as they go.
- “Add pack to cart” is enabled only when the total weight exactly matches the capacity (e.g. 5 × 200 g = 1000 g).
- The customer can add more packs with different combinations to the same cart and check out once.
