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 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
