magento 获取分类及其子分类 多种情况举例
分类：magento
magento
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; ?><< — 代码整理自网络搜集总结 —>>
