Getting Number Of Products in Basket From Certain Departments In Owebia

[calculus software solutions_web]

Hi there,

  This is a question about the Owebia Advanced Shipping Module configuration. I am trying to write a variable to be used in the shipping methods but having no joy so far. The below attempts to check how many items in the shopping basket are from departments 2 or 3 and times it by 5. What am i doing wrong here?

$dishwashers = function ($allItems) {
    return array_sum(
        return array_map(
            function ($item) {
                return count(array_intersect($item->product->category_ids, [2, 3]))
                ? $item->qty 
                : 0;
            },
            $request->all_items
        )
    ),
};
