I want to make a recommendation for each article based on the category of the current article,
The code writing function below is implemented, but there is a very serious problem, that is, the comment has a problem,
After the following code is added, the comments to the article are classified comments. each article is classified, and the post-comments are changed to other pages.

PHP code

  
  
  Cat_ID. ','; // The ID of the current article category // echo $ category-> cat_name. ''; // name of the current document category} $ my_query = new WP_Query (" cat = ". $ cat_id. "& posts_per_page = 5"); while ($ my_query-> have_posts (): $ my_query-> the_post ();?>
        
   "Alt =" "title ="
   "/>
   /Images/dummy.png "alt =" "title ="
   "/>
       
"Title =" "> 
  

------ Solution --------------------

PHP code

$ Cat_id. = $ category-> cat_ID. ','; // The ID of the category of the current article
------ Solution --------------------

Check whether your $ id is changed by the loop you added.
