我想就我的查询寻求一些帮助。

我创建了一个 CMS 页面，并希望在列表中显示特定类别的产品。所以我创建了一个模块并粘贴了 catalog/product/list.phtml 中的完整代码，以查看它是否可行...

不幸的是，我收到了这个错误: fatal error :在/Applications/MAMP/htdocs/mysite/app/design/frontend/bootstrapped/default/template/中的非对象上调用成员函数 count() cmsproducts/index.phtml 第 23 行

这是来自 list.phtml 的代码

</div>
<?php endif; ?>

对于我的 CMS block :

{{block type="core/template" category_id="41" template="cmsproducts/index.phtml"}}

我的自定义模块的 indexController.php:

<?php
class Thaneuk_Cmsproducts_IndexController extends Mage_Core_Controller_Front_Action{
    public function IndexAction() {  
    }
}

我四处寻找将类别中的产品添加到 CMS 页面的方法，但每种方法都会导致错误或产品不显示。

任何人都可以帮助我或向我推荐有效的分步指南吗？

提前致谢

最佳答案

使它不抛出错误的简单修复是

<?php if(is_object($_productCollection) && !$_productCollection->count()): ?>

但是您仍然需要找出代码中的缺陷，以了解为什么 $_productCollection 没有被加载。

关于php - fatal error : Call to a member function count() on a non-object in，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/13628751/
