Magento的1.7.0.2
我试图下面的代码编辑： http://www.dnawebagency.com/displaying-new-products-in-magento-with-pagination
我有一直在与我设置的服务器上进行斗争，希望尽快上线，但我无法实现它。我收到以下输出：
致命错误：调用/app/design/frontend/default/cscolors/template/catalog/product/list.phtml行中的非对象的成员函数count（） 35 35
行写着：
<?php if(!$_productCollection->count()): ?>
我能得到这个在一个干净的Magento的有几样产品的安装工作，但由于某种原因，我不能让他工作了甚至按照相同的程序。
我不知道从哪里开始调试这种情况，并找出为什么它挂在那行代码，所以任何建议或想法什么看待将不胜感激。在这个服务器上有更多的代码编辑，但他们应该远离这个问题。两个服务器之间的唯一区别实质上是几个Magento Connect附加组件以及当前主题中包含的一些额外功能和模板代码编辑。
我尝试过使用其他主题，所以某些地方出现了错误的New.php文件，但它是我在新的测试服务器上工作的一个确切副本，所以我很困惑到哪里去从这里。 （据我所知）中仅有的两个文件是上面链接中提到的两个文件，/ app/code/local/Mage/Catalog/Block/Product中的New.php，以及/应用程序/设计/前端/默认/ currentthemedir /模板/目录/产品。 （这在技术上也是无关紧要的，因为我使用默认的list.phtml文件得到相同的错误）
希望我充分描述了这一点，如果需要，我可以提供更多代码，但如前所述，我直接从上面的链接。
以下是一些完整的文件。

'$ _productCollection-> count（）'是magento方法，用于检索产品数量在列表页上 – Mufaddal
@Satish：对不起，这是错误的。非对象错误意味着根本没有类的实例，而是$ _productCollection === null。 –
好的，我纠正了我的回复更具体。 – oscprofessionals
