来自对象管理器的子类别 ID 的产品集合，其中子类别是在位于根类别之外的自定义类别中创建的

Question

我想要基于类别 ID 的特定类别的所有产品。

我已经尝试过下面的代码但没有解决：

$objectManager = \Magento\Framework\App\ObjectManager::getInstance(); 
$cateinstance = $objectManager->create('Magento\Catalog\Model\CategoryFactory');
$allcategoryproduct = $cateinstance->create()->load($cateid)->getProductCollection()->addAttributeToSelect('*');

[{"entity_id":"245","sku":"U001","type_id":"simple","category_id":null,"cat_index_position":"0","product_image":"\/p\/e\/peach-boy-boys-shirts_1_a8c05a1421e5dcf8ad5308398e0b3591_1.jpg","small_image":"\/p\/e\/peach-boy-boys-shirts_1_a8c05a1421e5dcf8ad5308398e0b3591_1.jpg","thumbnail":"\/p\/e\/peach-boy-boys-shirts_1_a8c05a1421e5dcf8ad5308398e0b3591_1.jpg","productName":"DY Andheri Peach School Uniform","price":"500.0000","isProductInStock":19,"isProductEndorsed":false,"option_collection":[]},{"entity_id":"250","sku":"U003","type_id":"configurable","category_id":null,"cat_index_position":"0","product_image":"\/0\/a\/0aea950b-1c0a-4adf-85ce-c521555462651534842479667-chalk-by-pantaloons-girls-dresses-4851534842479574-1.jpg","small_image":"\/0\/a\/0aea950b-1c0a-4adf-85ce-c521555462651534842479667-chalk-by-pantaloons-girls-dresses-4851534842479574-1.jpg","thumbnail":"\/0\/a\/0aea950b-1c0a-4adf-85ce-c521555462651534842479667-chalk-by-pantaloons-girls-dresses-4851534842479574-1.jpg","productName":"DY Andheri Girls School Uniform","price":"450.0000","isProductInStock":0,"isProductEndorsed":false,"option_collection":[{"sku":"DY Andheri Girls School Uniform-S","product_id":"250","attribute_id":"151","default_title":"Size","value_index":"30","display_label":"S","price":"450.0000"},{"sku":"DY Andheri Girls School Uniform-M","product_id":"250","attribute_id":"151","default_title":"Size","value_index":"31","display_label":"M","price":"450.0000"},{"sku":"DY Andheri Girls School Uniform-L","product_id":"250","attribute_id":"151","default_title":"Size","value_index":"32","display_label":"L","price":"450.0000"},{"sku":"DY Andheri Girls School Uniform-XL","product_id":"250","attribute_id":"151","default_title":"Size","value_index":"33","display_label":"XL","price":"450.0000"}]}]

Answer 1

您可以通过

获取特定类别的产品集合

        $categoryId = 3;
        $objectManager =  \Magento\Framework\App\ObjectManager::getInstance(); 
        $categoryFactory = $objectManager->create('Magento\Catalog\Model\CategoryFactory');
        $category = $categoryFactory->create()->load($categoryId);

        $productCollectionFactory = $objectManager->create('Magento\Catalog\Model\ResourceModel\Product\CollectionFactory');
        $collection = $productCollectionFactory->create();
        $collection->addAttributeToSelect('*');
        $collection->addCategoryFilter($category);
        $collection->addAttributeToFilter('visibility', \Magento\Catalog\Model\Product\Visibility::VISIBILITY_BOTH);
        $collection->addAttributeToFilter('status',\Magento\Catalog\Model\Product\Attribute\Source\Status::STATUS_ENABLED);

您可以将 categoryId 替换为您的类别 ID，集合将返回所有已启用且可见性设置为目录搜索且属于指定类别的产品
