Question

我有一个简单的两级结构的类别，如下所示：

Category #1
- Subcategory
- Subcategory
- ...
Category #2
- Subcategory
- Subcategory
- ...

目前要按子类别过滤 - 您必须先选择顶级类别。

如何在分层导航过滤器中显示所有顶级类别的子类别？

注意：子类别应受其他选定属性过滤器的影响。

在尝试使用Magento文件时，我找到了问题的答案。

复制

app/code/core/Mage/Catalog/Model/Layer/Filter/Category.php

至

app/code/local/Mage/Catalog/Model/Layer/Filter/Category.php

打开复制的文件。并使用以下代码替换_getItemsData：

/**
 * Get data array for building category filter items
 *
 * @return array
 */
protected function _getItemsData()
{
  $key = $this->getLayer()->getStateKey().'_SUBCATEGORIES';
  $data = $this->getLayer()->getAggregator()->getCacheData($key);

  if ($data === null) {
    // Get root category
    $root_category = Mage::getModel('catalog/category')->load(2);

    // Get main categories
    $data = array();
    $main_categories = $root_category->getChildrenCategories();
    foreach ($main_categories as $main_category) {
      if (!$main_category->getIsActive()) continue; // Ommit inactive
      // Get sub categories to list
      $sub_categories = $main_category->getChildrenCategories();

      // Add count to subcategories
      $this->getLayer()->getProductCollection()
        ->addCountToCategories($sub_categories);

      foreach ($sub_categories as $sub_category) {
        // Ommit inactive and zero product count sub categories
        if ($sub_category->getIsActive() || !$sub_category->getProductCount()) continue;

        // Output subcategories
        $data[] = array(
          'label' => Mage::helper('core')->htmlEscape($sub_category->getName()),
          'value' => $sub_category->getId(),
          'count' => $sub_category->getProductCount(),
          'parent' => $main_category->getName(), // Store parent name to group in template
        );
      }
    }

    $tags = $this->getLayer()->getStateTags();
    $this->getLayer()->getAggregator()->saveCacheData($data, $key, $tags);
  }
  return $data;
}

您可能有兴趣重写其他一些功能，例如getResetValue等。我不得不重写模板以按主要类别对子类别进行分组。

您可以使用以下代码在侧边栏或任何地方显示当前类别的所有子类别

<?php $_helper = Mage::helper('catalog/category') ?>
<?php $_categories = $_helper->getStoreCategories() ?>
<?php $currentCategory = Mage::registry('current_category') ?>
<?php if (count($_categories) > 0): ?>
    <ul>
        <?php foreach($_categories as $_category): ?>
            <li>
                <a href="<?php echo $_helper->getCategoryUrl($_category) ?>">
                    <?php echo $_category->getName() ?>
                </a>
                <?php $_category = Mage::getModel('catalog/category')->load($_category->getId()) ?>
                <?php $_subcategories = $_category->getChildrenCategories() ?>
                <?php if (count($_subcategories) > 0): ?>
                    <ul>
                        <?php foreach($_subcategories as $_subcategory): ?>
                            <li>
                                <a href="<?php echo $_helper->getCategoryUrl($_subcategory) ?>">
                                    <?php echo $_subcategory->getName() ?>
                                </a>
                            </li>
                        <?php endforeach; ?>
                    </ul>
                <?php endif; ?>
            </li>
        <?php endforeach; ?>
    </ul>
<?php endif; ?>
