如何从类别中获取所有产品,包括Magento中的子类别? [英] How to get all product from a category including its subcategories in Magento?
问题描述
我正在寻找一种从一个类别(包括其子类别)中检索所有产品并向我返回产品集合的方法.
I'm looking for a way to retrieve all products from a category includings its subcategories and return me a Product Collection.
我知道我可以遍历类别以获取产品ID并将其加载到视图中,但是我希望获得一个产品集合,因为目前在大多数类别/视图中都已完成.
I know I can iterate over categories to get ids of product and load them in the view, but I would have liked to get a product collection as it is done currently in most categories/views.
有什么想法吗?
推荐答案
我已经通过在产品收集模型中实现addCategoriesFilter解决了此问题,这是补丁.修改后的代码将被复制到local
池中,以允许更新到较新的版本.
I've solved this problem by implementing addCategoriesFilter in product collection model, here is the patch. Modified code to be copied to the local
pool to allow updates to a newer version.

用法:

$categories = $category->getAllChildren(true);
$collection = Mage::getResourceModel('catalog/product_collection');
$collection->addCategoriesFilter($categories);
