Question

第二级别类别中的getProductCount（）回显计数打印0，我尝试不同的方式，但我没想到像法师得到收集等，我没有在这个问题找到任何解决方案

  <?php
$_category  = $this->getCurrentCategory();
$collection = Mage::getModel('catalog/category')->getCategories($_category->entity_id);
$helper     = Mage::helper('catalog/category');
?>
  <?php foreach ($collection as $cat):?>

  <?php 
  $cur_category = Mage::getModel('catalog/category')->load($cat->getId());
  $_img = $cur_category->getThumbnailUrl();
  ?>
  <div class="grid_4">
<div class="mineContent_grid_4">

 <dl>
  <dt>
    <a href="<?php echo $helper->getCategoryUrl($cat);?>">
        <?php echo $cat->getName();?>
        <img src="<?php echo $_img?>" title="<?php echo $cat->getName();?>" width="173" height="208"/>
    </a>
  </dt>    
    <?php $childLevel2Category = Mage::getModel('catalog/category')->getCategories($cat->entity_id);
    ?>
    <dd>
        <ol>
          <?php foreach ($childLevel2Category as $catLevel2) { ?>
          <?php
           $cur_category2 = Mage::getModel('catalog/category')->load($cat->getId());
           $count = $cur_category2->getProductCount();
          ?>

          <li> <a href="<?php echo $helper->getCategoryUrl($catLevel2);?>"><?php echo $catLevel2->getName();?> <span>(<?php echo $count ?>)</span></a></li>
          <?php } ?>
        </ol>
    </dd>
    </dl>
</div>
</div>
  <?php endforeach;?>

Answer 1

您有以下代码：

<?php
   $cur_category2 = Mage::getModel('catalog/category')->load($cat->getId());
   $count = $cur_category2->getProductCount();
?>

这会加载$cur_category2 $cat->getId()，这是您的父类，而不是当前类别。我想你想要这个：

<?php
   $cur_category2 = Mage::getModel('catalog/category')->load($catLevel2->getId());
   $count = $cur_category2->getProductCount();
?>

Answer 2

这是一个可以帮助你的片段。我的所有代码片段都是获取该类别的产品数量。我将类别ID硬编码为4，但您的代码应该有效，获取当前类别。您可能希望将此代码隔离到一个函数中以使其更简单，然后只需从现有页面引用它。它基本上按类别加载一系列产品，过滤掉不可见的产品。

$_category = Mage::getModel('catalog/category')->load(4);

$collection = Mage::getResourceModel('catalog/product_collection')->addCategoryFilter($_category);
Mage::getSingleton('catalog/product_status')->addVisibleFilterToCollection($collection);
Mage::getSingleton('catalog/product_visibility')->addVisibleInCatalogFilterToCollection($collection);

echo $collection->count();

Answer 3

试试这个例子

$categories = Mage::getModel('catalog/category')->load(2)->getChildrenCategories();
$productCollection = Mage::getResourceModel('catalog/product_collection');
$productCollection->addCountToCategories($categories);

var_dump($categories);

其中2 - 类别ID 还要检查Magento中的php class Mage_Catalog_Block_Navigation

子类别上的Magento getProductCount（）
