Google Product Search Feeder II [Support Thread]

Actually, what I've done hasn't worked as it adds the '666' to all products. Back to the drawing board.

Right, you'd need to check the incoming $products_id value and possibly the $product/$categories_list/$cPath arrays to see if the current product 'qualifies' for the change.

For what I think you're trying to do:

public function getProductsAttributes(string $products_id, array $product, array $categories_list, array $cPath, array $custom_fields): array 
    {
        if (!in_array(66, $cPath)) {
            return [];
        }
        $extension_custom_fields = ['product_type' => '666',]; 

        return $extension_custom_fields; 
    } 

That checks to see if categories-id 66 is present in the current product's category-tree, returning the 'product_type' override if so; otherwise, no override is supplied.
