PHP代碼從Magento的sitemap.xml中排除特定的類別頁面

Question

我想包括我的Magento網站的sitemap.xml這些頁面，這些頁面不應被搜索引擎編入索引。爲此，我已將Catalog/Category.php Cms/Page.php複製到我的相應app/code/local目錄中，並且正在修改它。

我已成功修改Page.php以從我的sitemap.xml中排除特定的CMS頁面。我按照給出的指示here

因爲我不熟悉PHP，我不知道如何更改以適應此解決方案的Category.php文件。

這裏有沒有從sitemap.xml排除任何特定類別的網頁我想我現在的Category.php文件：

<?php

編輯：非常感謝盧克在下面他的評論！這是對我有用的東西。我不得不修改代碼，因爲直到if語句之後才定義$ 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; 
} 

我創建的類ID的類屬性，就像盧克說：

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

Answer 1

對於一個快速的解決方案中添加如下代碼，更好的方法是將屬性添加到然後使用類別EAV來檢查它是否應包含在站點地圖輸出中。

對於快速劈，添加的陣列爲一類屬性應被忽略的類別ID，

保護$ ignoreCategories =陣列（「2」，「3」，「16」）;

然後靠近getCollection（）對這些ID的功能檢查的底部，

而（$行= $查詢 - >取（））{

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

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

}
