WordPress can customize the code to get related articles

Insert the following code into the functions.php

Get policies for related articles: Manually specify > tags > Categories > Random

//related articlesfunctionAdd_related_posts ($content){    return $content.wp_related_posts ();} Add_filter (' The_content ', ' add_related_posts ');//Hookfunctionwp_related_posts () {Global $post; $num= 5;//Number of articles    $counter= 1; $exclude _id= Get_post_meta ($post->id, ' related ',true);//get related articles for manual pinning    if($exclude _id){        $args=Array(            ' Post_status ' = ' publish ', ' Post_type 'Array(' Post '), ' post__in ' =Explode(‘,‘,$exclude _id), ' posts_per_page ' =$num        ); $posts= Get_posts ($args); foreach($posts  as $SB){            $output. = ' <li><a href= '.

If you want to add a custom related article, just create a new custom column, add the article ID, multiple articles in English, separated

If you want to customize the position and adjust the style, the_content then remove the hooks and then call the wp_related_posts function manually
