Question

在我的目录页面上，我想获得当前有效的顶级类别。

示例：

1. Top Level Category
  1.1 Sub Category
    1.1.1 Sub sub Category
    1.1.2 Sub sub Category
  1.2 Sub Category
2. Top Level Category
  2.1 Sub Category
  2.2 Sub Category

假设我在子分类1.1.1中。我怎么知道'1。顶级类别'是当前的顶级类别？

我尝试了以下内容，但它对我不起作用：

            <?php $_cat_helper = Mage::helper('catalog/category') ?>
            <?php $_categories = $_cat_helper->getStoreCategories() ?>

            <?php foreach ($_categories as $_category): ?>
                <?php if ($this->isCategoryActive($_category)): ?>
                <?php echo $_category->getName() ?> <br>
                <?php endif; ?>
            <?php endforeach; ?>

请帮助： - ）

如果我将$this->isCategoryActive($_category)放入catalog / product / list.phtml，我会收到以下错误：

Invalid method Mage_Catalog_Block_Product_List::isCategoryActive(Array
(
    [0] => 
)
)


Trace:
#0 .../default/template/catalog/product/list.phtml(53): Varien_Object->__call('isCategoryActiv...', Array)
#1 .../default/template/catalog/product/list.phtml(53): Mage_Catalog_Block_Product_List->isCategoryActive(NULL)

Answer 1

获取当前类别并爬上类别树。您想要级别2类别（级别1是目录根目录）。尝试这样的事情：

$category = Mage::getModel('catalog/category')
                    ->load(Mage::registry('current_category'));

while ($category->getLevel() != 2) {
    $category = Mage::getModel('catalog/category')
                        ->load($category->getParentId());
}

Answer 2

想出来：

<?php $_categories = $this->getStoreCategories();?>

<?php foreach($_categories as $_category): ?>
      <?php if($this->isCategoryActive($_category)): ?>
            <?php echo $_category->getName(); ?>
      <?php endif; ?>
<?php endforeach; ?>

确保块类型为catalog/navigation
