1. 获取指定分类id 下的子分类
// 例如获取 分类id为 13 的子分类信息
<?php
$root = Mage::getModel('catalog/category')->load(13);
$subCat = explode(',',$root->getChildren());
$collection = $root
->getCollection()
->addAttributeToSelect("*")
->addFieldToFilter("entity_id", array("in", $subCat) );
foreach($collection as $catname){
echo $catname->getName();
echo '<br>';
echo $catname->getUrl();
}
?>
echo '<br>';
//echo $catname->getProductCount(); //获取目录下的产品数量
//echo $catname->getChildrenCount(); //获取目录下子目录数量
2. 显示所有分类和子分类
<?php $_helper = Mage::helper('catalog/category') ?>
<?php $_categories = $_helper->getStoreCategories() ?>
<?php if (count($_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; ?>
3.获取所有的一级分类信息
<?php $_helper = Mage::helper('catalog/category') ?>
<?php $_categories = $_helper->getStoreCategories() ?>
<?php if (count($_categories) > 0): ?>
<ul>
<?php foreach($_categories as $_category): ?>
<li>
<a href="<?php echo $_helper->getCategoryUrl($_category) ?>">
<?php echo $_category->getName() ?>
</a>
</li>
<?php endforeach; ?>
</ul>
<?php endif; ?>
4.获取所有的一级分类和当前分类的子分类信息
<?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 $_category->getName() ?>
</a>
<?php if ($currentCategory && $currentCategory->getId() == $_category->getId()): ?>
<?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; ?>
<?php endif; ?>
</li>
<?php endforeach; ?>
</ul>
<?php endif; ?>
