本文章来给各位朋友介绍Magento 修正来自首页的产品页面包屑导航实现方法,如果产品是从Category产品列表中进入Product详细页面,则面包屑导航中含有Category Path; 否则,当从首页,或搜索结果中,或者其他什么地方进入,则缺少之。我想,可能是Magento支持一个产品放入多个Category的缘故吧。不管怎么样,产品页中缺少了Category Path,用户体验不大好。

修正的方法,找到文件app/code/core/Mage/Catalog/Helper/Data.php

复制一份到local代码池

app/code/local/Mage/Catalog/Helper/Data.php
在函数getBreadcrumbPath的开始部分,加上如下的代码逻辑:

 

 代码如下 复制代码
getBreadcrumbPath()
    {
        if (!$this->_categoryPath) {
            $path = array();
            //add by date 2013-04-07 产品页面包屑导航修正
            if ($this->getProduct() && !$this->getCategory()) {
                $_categoryIds = $this->getProduct()->getCategoryIds();
                rsort($_categoryIds);
                if ($_categoryId = $_categoryIds[0]) {
                    $_category = Mage::getModel('catalog/category')->load($_categoryId);
                    Mage::register('current_category', $_category);
                }
            }
            //end date 2013-04-07
           
            if ($category = $this->getCategory()) {
                $pathInStore = $category->getPathInStore();
                $pathIds = array_reverse(explode(',', $pathInStore));
                $categories = $category->getParentCategories();
                // add category path breadcrumb
                foreach ($pathIds as $categoryId) {
                    if (isset($categories[$categoryId]) && $categories[$categoryId]->getName()) {
                        $path['category'.$categoryId] = array(
                            'label' => $categories[$categoryId]->getName(),
                            'link' => $this->_isCategoryLink($categoryId) ? $categories[$categoryId]->getUrl() : ''
                        );
                    }
                }
            }
            if ($this->getProduct()) {
                $path['product'] = array('label'=>$this->getProduct()->getName());
            }
            $this->_categoryPath = $path;
        }
        return $this->_categoryPath;
    }

首先判断当前是否是产品页,如果是并且没有Category信息,就获取产品所属的Category IDs,Magento中一个产品可以加入多个Category中,现在也不管那么多了,只挑出其中一个幸运的Category作为current_category
