如何使用Magento块显示多个类别 [英] How to display multiple categories with a Magento block

问题描述

我的Magento主页上当前有此代码段，可以很好地显示所有产品.

My Magento homepage currently has this code snippet that displays all products just fine.

{{block type="catalog/product_list"  category_id="2" template="catalog/product/list.phtml"}}

大致上，我的类别树看起来与此类似

Roughly, my category tree looks similar to this

id 2 (root cat)
-> id 3
-> id 4
-> id 5

由于我添加的每个产品都是ID为2的子级-每个产品都会显示在首页上.我需要的是一个解决方案，可以让我从首页产品列表中排除特定ID(类别).

Since every product I add is a child of id 2 - every product shows up on the homepage. What I'm after is a solution that will allow me to exclude specific id's (categories) from the home page product list.

我尝试了以下代码片段，但均未成功:

I've tried this snippet below with no success:

{{block type="catalog/product_list"  category_id="2,3,5" template="catalog/product/list.phtml"}}

推荐答案

您的代码{{block type="catalog/product_list" category_id="2,3,5" template="catalog/product/list.phtml"}}将不起作用，因为块Mage_Catalog_Block_Product_List仅加载一个类别$category = Mage::getModel('catalog/category')->load($this->getCategoryId());.

Your code {{block type="catalog/product_list" category_id="2,3,5" template="catalog/product/list.phtml"}} won't work because the block Mage_Catalog_Block_Product_List load only one category $category = Mage::getModel('catalog/category')->load($this->getCategoryId());.

我为您的问题提供了两种解决方案，您可以使用不同的类别ID多次使用该块:

I see two solutions for your problem, you can use the block more than once with a different category id:

{{block type="catalog/product_list"  category_id="2" template="catalog/product/list.phtml"}}
{{block type="catalog/product_list"  category_id="3" template="catalog/product/list.phtml"}}
{{block type="catalog/product_list"  category_id="5" template="catalog/product/list.phtml"}}

或覆盖块Mage_Catalog_Block_Product_List并更改此零件的行为

Or overwrite the block Mage_Catalog_Block_Product_List and change the behavior of this part

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

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

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