New Options Attributes Stock Addon

[raiwa]

app.php/addons/paid_addon/options_attributes_stock/

The Options & Attributes Stock addon extends the standard PhoenixCart inventory system by adding flexible stock control for individual product options and attributes. It is designed for products where a single option (such as ring size, chain length, or clothing size) requires its own inventory management.
Features

Four Stock Tracking Modes

Untracked – Option and attribute stock is not monitored.
Product Attribute Tracking – Stock is managed individually for each product attribute. The attribute values are linked to their corresponding entries on the Product Attributes page. (Limited to one option per product)
Attribute Value Tracking – Stock is managed by the attribute value itself, allowing the same value to be shared across multiple products. Values are linked to the Product Attributes page.
Referenced Product Tracking – Stock is managed by a separate product. Each attribute value is linked to a product in Categories/Products, allowing multiple products to share the same inventory.

Automatic Stock Validation
Prevents customers from purchasing attribute values that are out of stock.
Keeps inventory accurate throughout the shopping and checkout process.
Includes a Pi Layout module which replaces the PhoenixCart core Options & Attributes module
Optional setting to show attributes in drop-down menus or radio button groups.

Typical Use Cases

The Options & Attributes Stock addon is suitable for products where a specific option requires independent inventory management.
Examples

Jewellery
A sterling silver ring can use Product Attribute Tracking for available ring sizes, allowing each size to have its own stock level.
Different stone types can be created as separate products, each with its own images, pricing, and inventory. These products can then be displayed using the PhoenixCart Related Products Addon and its integrated layout module.
A pendant can use Attribute Value Tracking for additional options such as different silver chain types (for example, snake chain, box chain, or other chain styles) when these chains are only offered as selectable options and their stock is managed independently from the pendant.
If the same chains are also sold separately as products, Referenced Product Tracking can be used instead, linking the pendant's chain options directly to the corresponding chain products. This allows the same inventory to be shared between pendant selections and standalone chain sales.
Household Appliances
A kitchen fume extractor can use Attribute Value Tracking for optional mounting or installation kits.
The same kit values can be used across different appliance products while maintaining their own stock levels, without requiring each kit to be created as a separate product.
Footwear
Shoes can use Product Attribute Tracking for available shoe sizes, ensuring that each size has its own inventory level.
Different colours or models can be managed as separate products when they require individual images, prices, or stock control.
