Magento产品按类别划分

Question

有谁知道如何从Magento的视图文件中获取属于特定类别的产品列表？

Answer 1

您可以使用magento对象进行过滤.

例:

$categoryId = 123; // a category id that you can get from admin
$category = Mage::getModel('catalog/category')->load($categoryId);

$products = Mage::getModel('catalog/product')
    ->getCollection()
    ->addCategoryFilter($category)
    ->load();

print_r($products);

Answer 2

这一切都取决于你所处的观点.;-)

首先,我希望你留在你的模板集中(在我的例子中默认).

以此为例:

<?php
$_cat         = $this->getCurrentCategory();
$_parent      = $_cat->getParentCategory();
$_categories  = $_parent->getChildren();

/* @var $category Mage_Catalog_Model_Category */
$collection = Mage::getModel('catalog/category')->getCollection();
/* @var $collection Mage_Catalog_Model_Resource_Eav_Mysql4_Category_Collection */
$collection->addAttributeToSelect('url_key')
    ->addAttributeToSelect('name')
    ->addAttributeToSelect('is_anchor')
    ->addAttributeToFilter('is_active', 1)
    ->addIdFilter($_categories)
    ->setOrder('position', 'ASC')
    ->joinUrlRewrite()
    ->load();

$productCollection = Mage::getResourceModel('catalog/product_collection');
$layer             = Mage::getSingleton('catalog/layer');
$layer->prepareProductCollection($productCollection);
$productCollection->addCountToCategories($collection);
// $productCollection should be ready here ;-)
?>

我正在使用上面的代码在我的模板中显示姐妹类别 - 它不是理想的但它有效.

这有点像黑客,因为我还没有时间学习所有布局XML疯狂.否则,如果您使用XML,则需要记住 - 这一切都取决于您所处的位置.其中表示模板文件,基本上也表示布局(就app/design/frontend/default/default/layout/*而言).

我知道这并不多,但我希望能帮助你入门.

以下是从任何特定类别获取产品的代码.您也可以在视图文件中使用它.

// if you want to display products from current category
$category = Mage::registry('current_category'); 

// if you want to display products from any specific category
$categoryId = 10;
$category = Mage::getModel('catalog/category')->load($categoryId);

$productCollection = Mage::getResourceModel('catalog/product_collection')
                                 ->addCategoryFilter($category);

// printing products name
foreach ($productCollection as $product) {
    echo $product->getName(); 
    echo "<br />";
}

<?php
$c_id = 2;
$category = new Mage_Catalog_Model_Category();
$category->load($c_id);
$collection = $category->getProductCollection();
$collection->addAttributeToSelect('*');
foreach ($collection as $_product) { ?>
<a href="<?php echo $_product->getProductUrl(); ?>"><?php echo $_product->getName(); ?></a>
<?php } ?>
