Magento分层导航定制产品集合 [英] Magento layered navigation on custom product collection

问题描述

我一直在开发一个自定义模块Magento（版本1.8.0.0），显示一个产品的相关产品的列表。

为了实现这个我已经通过覆盖 Mage_Catalog_Block_Product_List 类创建了我自己的模块。

基本上这是如何工作： p>

从控制器捕获产品 entity_id ，我将产品存储在注册表中，以便我可以在我的自定义写为Block.php

这是填充产品集合的方法：

  protected function _getProductCollection（）
 {
 if（is_null（$ this-> _productCollection））{
 $ prod = Mage :: registry（'selectedproduct'） ; 
 $ this-> _productCollection = $ prod-> getRelatedProductCollection（）
  - > addAttributeToSelect（'required_options'）
  - > addAttributeToFilter（array（'attribute'=> ;'accessory_manufacturer'，'neq'=> false）））
  - > addAttributeToSort（'position'，'asc'）
  - > addStoreFilter（）
  - > setPageSize （30）
  - > setCurPage（1）; 
; 
 
 $ this-> _addProductAttributesAndPrices（$ this-> _productCollection）; 
 Mage :: getSingleton（'catalog / product_visibility'） - > addVisibleInCatalogFilterToCollection（$ this-> _productCollection）; 
 $ this-> setProductCollection（$ this-> _productCollection）; 
} 
 
 return $ this-> _productCollection; 
} 
  

我还在我的自定义模块的布局.xml中添加了以下内容确保分层导航显示：

 < reference name =left> 
< block type =catalog / layer_viewname =catalog.leftnavafter =currencytemplate =catalog / layer / view.phtml/> 
< / reference> 
  

分层导航显示，但似乎它将所有产品作为集合而不是自定义集合

我也知道我可以使用 $ layer = Mage ::获取目录/图层getSingleton（'catalog / layer'）;

图层类还有一个名为prepareProductCollection和setCollection的方法，

基本上我想为分层导航

感谢，

解决方案

我只是设法实现我想要的。我已覆盖 Mage_Catalog_Model_Layer 类和 Mage_Catalog_Model_Category

两个现在都有一个新的变量$ _customCollection： protected $ _customProductCollection;

我覆盖了getProductCollection在这两个类中，我在方法的开头添加了这个：

  if（isset（$ this-> _customProductCollection） {
 return $ this-> _customProductCollection; 
} 
  

我还有一个方法允许我设置这个customProductCollection这些类。一旦设置，分层导航/类别的其余数据基于此集合。

I have been working on a custom module for Magento (ver. 1.8.0.0) that shows a list of related products of a certain product.

In order to achieve this I have created my own module by overwriting the Mage_Catalog_Block_Product_List class.

Basically here's how it works:

From a controller I catch the products entity_id and I store the product in the registry so I can use it inside my custom written Block which is called list.php

Here is the method that fills the product collection:

protected function _getProductCollection()
{
    if (is_null($this->_productCollection)) {
        $prod = Mage::registry('chosenproduct');
        $this->_productCollection = $prod->getRelatedProductCollection()
            ->addAttributeToSelect('required_options')
            ->addAttributeToFilter(array(array('attribute'=>'accessory_manufacturer','neq'=>false)))
            ->addAttributeToSort('position', 'asc')
            ->addStoreFilter()
            ->setPageSize(30)
            ->setCurPage(1);
        ;

        $this->_addProductAttributesAndPrices($this->_productCollection);
        Mage::getSingleton('catalog/product_visibility')->addVisibleInCatalogFilterToCollection($this->_productCollection);
        $this->setProductCollection($this->_productCollection);
    }

    return $this->_productCollection;
}

I also added the following in the layout .xml of my custom module to make sure the layered navigation shows:

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

The layered navigation shows, but it seems that it is taking all products as collection instead of the custom collection that is used in the method I added above.

I also know that I can get the catalog/layer using this $layer = Mage::getSingleton('catalog/layer');

The layer class also has a method called prepareProductCollection and setCollection but for some reason I can't get it to work.

Any help on this?

Basically I want to have the layered navigation for the products that are in the custom collection.

Thanks,

解决方案

I just managed to achieve what I wanted. I have overwritten both the Mage_Catalog_Model_Layer class and the Mage_Catalog_Model_Category

Both now have a new variable called $_customCollection: protected $_customProductCollection;

I have overwritten the getProductCollection() in both classes and I added this in the beginning of the method:

if(isset($this->_customProductCollection)){
        return $this->_customProductCollection;
    }

I have also a method that allows me to set this "customProductCollection" inside both these classes. Once It's set, the rest of the data of the layered navigation/category is based on this collection.
