Question

我有一个自定义list.phtml页面。我复制了list.phtml页面并将其重命名为newlist.phtml页面。唯一的区别是我改变了

$_productCollection=$this->getLoadedProductCollection();

要

$_productCollection = Mage::getModel('catalog/product')
                        ->getCollection()->addFieldToFilter('status', array('neq' => 2))
                        ->addAttributeToSort('created_at', 'DESC')
                        ->addAttributeToSelect('*')
                        ->load();

通过在管理内容中添加以下内容来使用它

{{block type="catalog/product_list" name="home.catalog.product.list" alias="products_homepage" template="catalog/product/newlist.phtml"}}

以及布局更新中的

<reference name="left">

    <block type="catalog/layer_view" name="catalog.leftnav"  template="catalog/layer/view.phtml"/>

    </reference>

但是这个页面没有显示Layred Nav。但所有其他类似页面的页面都显示了分层导航。任何想法???

分层导航过滤器正在使用Mage::getSingleton('catalog/layer')对象。您正在从目录模型对象中直接查找产品集合，这会导致此处出现问题。

请在此处查看Magento的产品系列获取逻辑：

protected function _getProductCollection()
    {
        if (is_null($this->_productCollection)) {
            $layer = $this->getLayer();
            /* @var $layer Mage_Catalog_Model_Layer */
            if ($this->getShowRootCategory()) {
                $this->setCategoryId(Mage::app()->getStore()->getRootCategoryId());
            }

            // if this is a product view page
            if (Mage::registry('product')) {
                // get collection of categories this product is associated with
                $categories = Mage::registry('product')->getCategoryCollection()
                    ->setPage(1, 1)
                    ->load();
                // if the product is associated with any category
                if ($categories->count()) {
                    // show products from this category
                    $this->setCategoryId(current($categories->getIterator()));
                }
            }

            $origCategory = null;
            if ($this->getCategoryId()) {
                $category = Mage::getModel('catalog/category')->load($this->getCategoryId());
                if ($category->getId()) {
                    $origCategory = $layer->getCurrentCategory();
                    $layer->setCurrentCategory($category);
                    $this->addModelTags($category);
                }
            }
            $this->_productCollection = $layer->getProductCollection();

            $this->prepareSortableFieldsByCategory($layer->getCurrentCategory());

            if ($origCategory) {
                $layer->setCurrentCategory($origCategory);
            }
        }

        return $this->_productCollection;
    }

参考app / code / core / Mage / Catalog / Block / Product / List.php

Magento Layered Navigation没有出现在我的自定义list.phtml中
