我需要将我的自定义数据传递到同一级别的资源数组，但它超出了数组

return CategoryProductsResource::collection(Category::whereNull('parent_id')->get())
  ->additional([
                'data' => [
                    'id' => 9999,
                    'name' => 'How Offers',
                    'image' => 'http://businessdotkom.com/storage/categories/January2020/1o6nDi1kjVuwje5FiFXv.png',
                    'products' => ProductIndexResource::collection(Product::whereNotNull('sale_price')->get()),
                ]
            ]);

因为附加用于顶级数据，所以使用concat instaed。

return CategoryProductsResource::collection(Category::whereNull('parent_id')->get())
  ->concat([
                'data' => [
                    'id' => 9999,
                    'name' => 'How Offers',
                    'image' => 'http://businessdotkom.com/storage/categories/January2020/1o6nDi1kjVuwje5FiFXv.png',
                    'products' => ProductIndexResource::collection(Product::whereNotNull('sale_price')->get()),
                ]
            ]);

【解决方案2】：

你可以使用 PHP array_merge() 函数

$categories = Category::whereNull('parent_id')->get()->toArray();

$merged = array_merge($categories, [
           [
             'id' => 9999,
             'name' => 'How Offers',
             'image' => 'http://businessdotkom.com/storage/categories/January2020/1o6nDi1kjVuwje5FiFXv.png',
             'products' => ProductIndexResource::collection(Product::whereNotNull('sale_price')->get()),
           ]
]);

return CategoryProductsResource::collection(collect($merged));
