顶视图帖子未在 wordpress 中显示特色图片

Question

我试图在 wordpress 的 sidebar.php 中显示我浏览次数最多的帖子。

我尝试了以下代码，但它会重复显示一张特色图片 3 次。

这是link

我的代码是：

sidebar.php

<div class="popular">
<h2>Most Popular Posts</h2>

    <?php echo popularPosts(3); ?>

</div>   

function.php

<?php

function popularPosts($num) {
global $wpdb;

$posts = $wpdb->get_results("SELECT comment_count, ID, post_title FROM   $wpdb->posts ORDER BY comment_count DESC LIMIT 0 , $num");

foreach ($posts as $post) {
    setup_postdata($post);
    $id = $post->ID;
    $title = $post->post_title;
    $count = $post->comment_count;

    if ($count != 0) {
        $popular .= '<li>';
        $popular .= '<a href="' . get_permalink($id) . '" title="' . $title . '">' . $title .the_post_thumbnail(). '</a> ';
        $popular .= '</li>';
    }
}
return $popular;
   }

   ?>

我使用以下代码计算我的帖子浏览量。

 function bac_PostViews($post_ID) {

     //Set the name of the Posts Custom Field.
     $count_key = 'post_views_count'; 

     //Returns values of the custom field with the specified key from the specified post.
     $count = get_post_meta($post_ID, $count_key, true);

     //If the the Post Custom Field value is empty. 
     if($count == '')
     {
          $count = 0; // set the counter to zero.

          //Delete all custom fields with the specified key from the specified post. 
          delete_post_meta($post_ID, $count_key);

          //Add a custom (meta) field (Name/value)to the specified post.
          add_post_meta($post_ID, $count_key, '0');
          return $count . ' View';

          //If the the Post Custom Field value is NOT empty.
     }else{
          $count++; //increment the counter by 1.
          //Update the value of an existing meta key (custom field) for the specified post.
          update_post_meta($post_ID, $count_key, $count);

          //If statement, is just to have the singular form 'View' for the value '1'
          if($count == '1')
          {  
               return $count . ' View';
          }
          //In all other cases return (count) Views
          else 
          {
               return $count . ' Views';
          }
       }
    }
?>

请建议我如何使用特色图片和帖子标题显示三个最受欢迎的页面。
