Edit Shipping Weights

This program directly manages OpenCart 3 Weight-Based Shipping rates via the database settings layer. Rate tiers are stored as comma-separated weight:price pairs in oc_setting rows grouped under code = shipping_weight, with individual keys following the OpenCart 3 format shipping_weight_{geo_zone_id}_rate (for example, shipping_weight_5_rate).

• Add — enter a new weight/price pair in the top row and click Add.
• Update — saves the full rate table and propagates the same serialized value to every configured geo-zone rate key.
• Delete — removes a single weight tier from the table before the next save.
• Configured geo-zone IDs: 5, 6, 15, 19, 22, 23, 24.
• An optional (currently hidden) workflow can merge missing product weights from oc_product into the rate table.
