php - 致命错误：在非对象上调用成员函数 count()

Question

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。因此，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: Call to a member function count() on a non-object in /Applications/MAMP/htdocs/mysite/app/design/frontend/bootstrapped/default/template/cmsproducts/index.phtml on line 23

这是来自 list.phtml 的代码

        // need to set collection
        $pager->setCollection($_productCollection);
        //set custom template

        echo $pager->toHtml();
        ?>
    </div>
</div>
<?php endif; ?>

对于我的 CMS 块：

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

indexController.php 用于我的自定义模块：

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

我一直在寻找将产品从类别添加到 CMS 页面的方法，但每种方法都会导致错误或产品未显示。

任何人都可以帮助或向我推荐一个可行的分步指南吗？

使其不引发错误的简单修复将是

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

但是您仍然需要找出代码中的缺陷，即为什么$_productCollection没有加载。

解决了！！

<?php 
$category_id = "43"; // category_id for "Featured Products"
$_productCollection = Mage::getResourceModel('catalog/product_collection')
->addAttributeToSelect(array('name', 'price', 'small_image', 'short_description'), 'inner')
->addCategoryFilter(Mage::getModel('catalog/category')->load($category_id));
?>
<?php if($_productCollection->count()): ?>
      <div class="featured">
      <br />
      <ul id="featured-product-list">
        <div class="block-title">
      <h3><span><?php echo $this->__('FEATURED PRODUCT'); ?></span></h3>
    </div>
       <?php 
       $products = array();
       foreach ($_productCollection as $_product) { 
        ?>
        <li class="featured-product">
          <!--<h6>Price <?php echo Mage::helper('core')->currency($_product->getPrice());; ?></h6>-->
          <a href="<?php echo $_product->getProductUrl() ?>" title="<?php echo $this->htmlEscape($this->getImageLabel($_product, 'small_image')) ?>">
            <img class="product-image" src="<?php echo $this->helper('catalog/image')->init($_product, 'small_image')->resize(225, 200); ?>" alt="<?php echo $this->htmlEscape($this->getImageLabel($_product, 'small_image')) ?>" title="<?php echo $this->htmlEscape($this->getImageLabel($_product, 'small_image')) ?>" />
          </a>
        </li>
       <strong><a class="view-item-button" href="<?php echo $_product->getProductUrl() ?>" title="<?php echo $this->htmlEscape($_product->getName()) ?>"><?php echo $this->__('Order'); ?> <?php echo $this->htmlEscape($_product->getName())?><?php echo $this->__('&#8482;'); ?></a></strong>
        <div class="clearfix"></div>
        <p>
            <?php echo $_product->_data['short_description']; ?>
        </p>
        <div class="clearfix"></div>  
        <?php } ?>
      </ul>
</div>  
<?php endif; ?>

我也发生了同样的错误。我在 XAMPP 服务器上使用 magento 1.9.1。我只刷新了所有 magento 索引并且一切正常。

转到系统/索引管理选择所有选项并执行“重新索引数据”操作
