Php 在Magento 1.7中显示导航中每个类别的畅销书

我正在寻找一种可能性，以获得最畅销的产品类别，以显示在一个特定的导航部分。展示产品不是问题，而是获取产品

我已经用不同的关键词在谷歌上进行了密集搜索，但我得到的只是过时的插件、对bestseller.phtml的修改（它不再存在于Magento 1.7中）和在资源模型上设置过滤器，但我没有找到任何结果

所以我试着自己购买产品（到目前为止，它应该只获得任何产品的销量，而不是最好的）：

$category->getId（）；
$children=$category->getChildren（）；
foreach（$childrenas$child）
{
$childCategoryIdString=$child->getId（）；
$childCategoryId=substr（$childCategoryIdString，14）；
$childCategory=Mage:：getModel（'catalog/category'）
->加载（$childCategoryId）；
$productCollection=Mage:：getModel（'目录/产品'）
->getCollection（）
->addCategoryFilter（$childCategory）
->加载（）；
$allIds=$productCollection->getAllIds（）；
对于（$i=0；$iload（$allIds[$i]）；
echo$product->getOrderedQty（）.'uUZ'；
}
}

---

这有两个问题：首先，它使Magento更慢。第二个

$product->getOrderedQty（）

，我在各种搜索结果中找到的方法，不起作用。现在我真的不知道还有什么我可以尝试和寻找一些帮助，这是高度赞赏。谢谢

在示例脚本中使用了大量对象包装器。封装到多个循环中的

load

等方法将产生巨大的延迟，并且可能会占用大量内存（取决于产品集合的大小）

前几天，当我解决这个问题时，我决定使用直接的ORM方法而不是对象来获得更好的性能

展示畅销书有两种可能的方式。使用聚合畅销书表（如

sales\u bestsellers\u aggregated\u daily

）消耗的资源更少，但它有一个巨大的缺点——这些表中的数据不是自动更新的。它用于管理报告部分，只有当您选择刷新统计信息时才会更新

另一种但更可靠的方法是连接

sales\u flat\u order\u item

表以检索每个产品的sales\u数量。很明显，这会消耗更多的资源，因为你必须自己计算

在我的脚本中，我选择了后一条路径。我修改了它以满足您的逻辑要求。此外，我还添加了两个

联接

来获取类别名称，您可能不需要这些。但是说够了：）下面是我的

希望这有帮助

谢谢您的回复！不幸的是，这个代码段做了一些奇怪的事情，因为它输出了相同的两个产品的四倍（这表示至少echo$\u product->getId（）），而我加载的类别有六个项。因此，我希望他们或没有人（因为到目前为止还没有销售任何产品）。很抱歉我的回复太晚，但感谢您提供的信息丰富的答案！运行脚本将返回四个空数组。因为到目前为止还没有售出的产品，所以它们完全是空的（好吧，不应该至少是其中的文本字符串吗？）。我有四个父类别，但出于测试目的将$catId定义为“17”（我的子类别ID之一）。我监督过什么吗？只需注意一下，这些畅销书在万磁王的cron调度系统中被cron作业填充
