Laravel 4 - 迭代数组并将值输入刀片

我正在使用 etrepat/baum 并且我正在检索所有子类的根类别：

$children = $category->children()->get();

然后，为了检索存储在子类别下的所有产品，我正在进行foreach循环以获取子类别的id和另一个foreach将产品存储在 $children_products[] 数组中，如下所示：

// store the ids of the children categories
foreach ($children as $child) {
     $children_ids[] = $child->id;
}

// store the products that children categories have
foreach($children_ids as $val) {
     $children_products[] = Product::where('category_id', '=', $val)->get();
}

然后我将 $children_products 数组发送到视图以呈现结果 . 虽然，这是为每个子类别呈现为具有产品或为空的不同数组 .

[] [{"id":1,"category_id":21,"brand_id":1,"title":"test","description":"Etiam aliquam sem ac velit feugiat elementum. Nunc eu elit velit, nec vestibulum nibh. Curabitur ultrices, diam non ullamcorper blandit, nunc lacus ornare nisi, egestas rutrum magna est id nunc. Pellentesque imperdiet malesuada quam, et rhoncus eros auctor eu. Nullam vehicula metus ac lacus rutrum nec fermentum urna congue. Vestibulum et risus at mi ultricies sagittis quis nec ligula. Suspendisse dignissim dignissim luctus.","price":"1000.00","availability":1,"image":"img\/products\/2014-11-24-14:29:33-00064736.jpg","created_at":"2014-11-24 14:29:34","updated_at":"2014-11-24 14:29:34"}] [] [] [] [] []

有没有办法迭代这些数组并将产品存储在数组中？

    您可以简化产品查询：

    $children_products = Product::whereIn('category_id', $children->lists('id'))->get();

    那么也许只是迭代Blade中的值？

    @foreach ($children_products as $product)
{{ $product->title }}
@endforeach
