在 Magento 的单个产品页面上制作一致的面包屑?

问题描述

在 Magento 中，我们现在拥有的是单个产品页面上的面包屑总是根据用户到达页面的方式而变化.例如，如果用户从顶级类别一直点击到子类别，然后再到产品，面包屑将类似于首页 >> 顶级类别 >> 子类别 >> 产品".

In Magento, what we have now is that the breadcrumbs on individual product pages are always changing according to how the user has arrived at the page. For example, if user clicked all the way from top category to sub category and then to the product, the breadcrumbs would be something like "Home >> Top category >> Sub category >> Product".

但是，如果用户直接到达产品页面，例如通过 Google 查询，面包屑将只是首页 >> 产品".像这样很不酷.

However if the user arrives at the product page directly, such as from Google queries, the breadcrumbs would simply be "Home >> Product". And it is uncool to be like this.

通过在面包屑导航中添加类别肯定会改善用户体验，即使用户从 Google 到达页面也是如此.而且它肯定会增加每次访问的 PV，因为用户可能会点击面包屑中的父类别.

It would definitely be a user experience improvement by adding categories in the breadcrumbs even when the user arrives at the page from Google. And it would definitely increase PV per visit because users will likely to click on parent categories in the breadcrumbs.

那么有什么办法可以让它保持一致并始终在产品页面上显示类别路径?

So is there any way to make it consistent and always show the categories path on product pages?

我的想法是编辑 page/html/breadcrumbs.phtml 但我不知道如何仅在产品页面上为面包屑添加类别.

My idea is to edit page/html/breadcrumbs.phtml but I don't know how to add categories to the breadcrumbs only on product pages.

任何帮助将不胜感激！

======================================

总之，无论用户如何到达产品页面，我都希望类别出现在产品页面的面包屑中.只要类别存在，哪些类别无关紧要.

In a word, I just want categories to appear in the breadcrumbs on product pages no matter how the user arrives on the product page. Doesn't matter which categories, as long as the categories are there.

有人知道吗?有那么难吗?

Anyone got any idea? Is this that hard?

在我的头顶上，我需要编辑面包屑模板并在其中注入类别(如果没有任何类别，它是产品页面......但我不知道如何，我可以)似乎在任何地方都找不到任何相关的解决方案......

Off the top of my head, I will need to edit the breadcrumbs template and inject the categories in it if there aren't any and it's the product page....but I don't know how and I can't seem to find any relevant solutions to this anywhere...

推荐答案

用这个替换app/code/core/Mage/Page/Block/Html/Breadcrumbs.php"中的 _toHtml() 函数.

Replace _toHtml() function in "app/code/core/Mage/Page/Block/Html/Breadcrumbs.php" with this one.

protected function _toHtml() {             

   $cat_id = "";

   if (Mage::registry('current_product')) {
      $product_id = Mage::registry('current_product')->getId();
      $obj = Mage::getModel('catalog/product');
      $_product = $obj->load($product_id); // Enter your Product Id in $product_id

      if ($product_id) {
         $categoryIds = $_product->getCategoryIds();
         $cat_id = $categoryIds[0];
      }

      $category = Mage::getModel('catalog/category')->load($cat_id);
      $cat_name = $category->getName();
      $cat_url =  $this->getBaseUrl().$category->getUrlPath();
   }

   if (is_array($this->_crumbs)) {
      reset($this->_crumbs);
      $this->_crumbs[key($this->_crumbs)]['first'] = true;
      end($this->_crumbs);
      $this->_crumbs[key($this->_crumbs)]['last'] = true;
   }

   if($cat_id) {
      $this->_crumbs['category'.$cat_id] = array('label'=>$cat_name, 'title'=>'', 'link'=>$cat_url,'first'=>'','last'=>'','readonly'=>'');
      ksort($this->_crumbs);
      $home = $this->_crumbs['home'];
      unset($this->_crumbs['home']);
      array_unshift($this->_crumbs,$home);
   }

   $this->assign('crumbs', $this->_crumbs);
   return parent::_toHtml();
}
