Question

我正在尝试使用以下代码在我的主页上列出两组子类别。问题是第二个列表与第一个列表完全相同。它似乎没有识别第二类ID号。任何想法？

<?php
    $children = Mage::getModel('catalog/category')->getCategories(3);
      foreach ($children as $category):
            echo '<li><a href="' . $category->getUrl() . '">' . $category->getName() . '</a></li>';
      endforeach;
?>

<?php
    $children = Mage::getModel('catalog/category')->getCategories(4);
      foreach ($children as $category):
            echo '<li><a href="' . $category->getUrl() . '">' . $category->getName() . '</a></li>';
      endforeach;
?>

Answer 1

试试这个

<?php 
$_helper = Mage::helper('catalog/category');
$_category = Mage::getModel('catalog/category')->load(3);
$_subcategories = $_category->getChildrenCategories();
foreach($_subcategories as $_category){
      $category = Mage::getModel('catalog/category')->load($_category->getId());
      echo '<li><a href="' . $category->getUrl() . '">' . $category->getName() . '</a></li>';
}
?>

<?php 
$_helper = Mage::helper('catalog/category');
$_category = Mage::getModel('catalog/category')->load(4);
$_subcategories = $_category->getChildrenCategories();
foreach($_subcategories as $_category){
     $category = Mage::getModel('catalog/category')->load($_category->getId());
     echo '<li><a href="' . $category->getUrl() . '">' . $category->getName() . '</a></li>';
}
?>

此代码未经我测试。谢谢，

如果您只需要Url和子类别名称，则无需加载它们，因为它会降低网站性能

尝试，

$parentCategory = Mage::getModel('catalog/category')->load(15);
$subCategories = $parentCategory->getChildrenCategories();
foreach($subCategories as $curCategory){
    echo '<li><a href="' . $curCategory->getUrl() . '">' . $curCategory->getName() . '</a></li>';
}

这里是您使用类别ID，但我更喜欢url_key，因为开发类别ID和实时网站之间存在不匹配的可能性。

尝试，

$parentCategory = Mage::getModel('catalog/category')->loadByAttribute('url_key', 'computers');
$subCategories = $parentCategory->getChildrenCategories();
foreach($subCategories as $curCategory){
    echo '<li><a href="' . $curCategory->getUrl() . '">' . $curCategory->getName() . '</a></li>';
}

magento子类别显示
