我想包含我的 Magento 网站的 sitemap.xml 中不应被搜索引擎编入索引的那些页面。为此，我已将 Catalog/Category.php Cms/Page.php 复制到我相应的 app/code/local 目录中，我正在修改它。

我已成功修改 Page.php 以从我的 sitemap.xml 中排除特定的 CMS 页面。我按照给出的指示 here

由于我不熟悉 PHP，我不知道要使此解决方案适应 Category.php 文件需要做哪些更改。

这是我目前的 Category.php 文件，它不排除我想要从 sitemap.xml 中获取的任何特定类别页面:

 <?php

    return $this->_select;
}

编辑:非常感谢卢克在下面的评论中!这对我有用。我不得不稍微修改一下代码，因为直到 if 语句之后才定义 $category。

while ($row = $query->fetch()) {

// Added to exclude specific categories
if(in_array($this->_prepareCategory($row)->getId(), $this->ignoreCategories))
{
    continue;
}

$category = $this->_prepareCategory($row);
$categories[$category->getId()] = $category;
}

正如 Luke 所说，我为类别 ID 创建了类属性:

protected $ignoreCategories = array("2","3","16");//Replace the numbers with your category IDs

最佳答案

要获得快速解决方案，请添加以下代码，更好的方法是向类别 EAV 添加一个属性，然后使用它来检查它是否应包含在站点地图输出中。

为了快速破解，为应该忽略的类别 ID 添加一个数组作为类属性，

protected $ignoreCategories = array("2","3","16");

然后在 getCollection() 函数底部附近检查这些 ID，

while ($row = $query->fetch()) {

// Added to exclude specific categories
if(in_array($category->getId(), $this->ignoreCategories)
{
    continue;
}

    $category = $this->_prepareCategory($row);
    $categories[$category->getId()] = $category;
