Magento 1.7.0.2
我正在尝试以下代码编辑： http://www.dnawebagency.com/displaying-new-products-in-magento-with-pagination
我一直在我正在设置的服务器上与之斗争，希望很快就会上线，我无法让它工作。我收到以下输出：
致命错误：在第35行的/app/design/frontend/default/cscolors/template/catalog/product/list.phtml中调用非对象的成员函数count（）
第35行读到：
<?php if(!$_productCollection->count()): ?>
我能够通过一些样本产品来完成Magento的干净安装，但由于某种原因，即使按照相同的程序，也无法让它在新的Magent上工作。
我真的不知道从哪里开始调试这种情况并弄清楚它为什么会挂在那行代码上，所以任何有关什么的建议或想法都将非常感激。在这台服务器上还有一些代码编辑，但它们应该与这个问题分开。两台服务器之间的唯一区别主要是一些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。
我已经尝试过使用其他主题，所以使用New.php文件出错了，但是它是我在新测试服务器上工作的完全副本，所以我很困惑从哪里去这里。应该导致此问题的唯一两个文件（据我所知）是上面链接中提到的两个文件，/ app / code / local / Mage / Catalog / Block / Product中的New.php和/中的list.phtml应用程序/设计/前端/默认/ currentthemedir /模板/目录/产品。 （这在技术上与问题无关，因为我使用默认的list.phtml文件得到了相同的错误）
希望我能够充分描述这一点，如果需要，我可以提供更多代码，但如上所述，我直接从上面的链接中复制了它。
以下是一些完整的文件。

答案 0 :(得分：2)
致命错误：在第35行的/app/design/frontend/default/cscolors/template/catalog/product/list.phtml中调用非对象的成员函数count（）
你的行是count（））:?＆gt;
$ _ productCollection是一个非对象，因此您需要检查未创建实例的原因。
答案 1 :(得分：0)
我发现了问题，这是一个愚蠢的问题。感谢大家帮我解决这个问题。
将整个生产服务器复制到我的文件到文件后，错误显示在我的服务器上。我注意到用所有核心magento文件覆盖它修复了问题。
我对所有文件夹进行了差异比较并没有发现很多差异，所以我开始逐个替换文件夹以缩小范围。当我到达“/ includes /”时它就开始工作了。不同之处在于config.php文件。它是一个只有几行的小文件，区别仅仅是一个引用magento编译器的未注释行。
我忘记了我在生产服务器上启用并运行了编译器，编辑模板文件并没有像我这样给我带来问题。但是，功能代码是另一回事。重新运行编译器已经解决了我的问题，代码现在按预期工作。
