为DUX主题首页添加热门文章模块

在网络上浏览的时候，发现有的网站上用的DUX主题首页有个热门文章模块看着不错，就想着给网站也添加上，于是百度了一下，在蝈蝈要安静的网站上找到了，说是模仿XIU主题的，于是我就自己从XIU主题里提取需要的代码和文件为网站添加上了，具体效果如下图：

修改步骤如下：

1. 新建一个名为 hui_recent_posts_most.php 的文件，把下面这段代码保存到文件中，或者直接到XIU主题的models文件夹中直接提取出来，然后放入主题的models文件夹下即可，为什么是models文件夹呢？这是因为主题在 functions-theme.php 文件夹中添加了一个_moloader 的函数用于调取模板，这里为了方便我们直接使用该函数调取模板即可。

   <?php 
   /* 
    * recent post most
    * ====================================================
   */
   function hui_recent_posts_most() { 
       global $wpdb;
       // $days=400;
       $days=_hui('most_list_date');
       $limit=_hui('most_list_number');
       $output = '';
       
       if( !_hui('most_list_style') || _hui('most_list_style')=='comment' ){
   
           $today = date("Y-m-d H:i:s");
           $daysago = date( "Y-m-d H:i:s", strtotime($today) - ($days * 24 * 60 * 60) );  
           $result = $wpdb->get_results("SELECT comment_count, ID, post_title, post_date FROM $wpdb->posts WHERE post_date BETWEEN '$daysago' AND '$today' AND post_status='publish' AND post_type='post' ORDER BY comment_count DESC LIMIT 0 , $limit");
           if(empty($result)) {
               $output = '<li>'.__('暂无文章！', 'haoui').__('近期有评论的文章才会显示在这里，你也可以在主题设置中选择按阅读数排行。', 'haoui').'</li>';
           } else {
               $i = 1;
               foreach ($result as $topten) {
                   $postid = $topten->ID;
                   $title = $topten->post_title.get_the_subtitle();
                   $commentcount = $topten->comment_count;
                   if ($commentcount != 0) {
                       $output .= '<li><p class="text-muted"><span class="post-comments">'.__('评论', 'haoui').' ('.$commentcount.')</span></p><span class="label label-'.$i.'">'.$i.'</span><a href="'.get_permalink($postid).'" title="'.$title.'">'.$title.'</a></li>';
                       $i++;
                   }
               }
           }
   
       }else if( _hui('most_list_style')=='view' ){
   
           global $post;
           $limit_date = current_time('timestamp') - ($days*86400);
           $limit_date = date("Y-m-d H:i:s",$limit_date);
           $where = '';
           $mode = 'post';
   
           if(!empty($mode) && $mode != 'both') {
               $where = "post_type = '$mode'";
           } else {
               $where = '1=1';
           }
   
           $most_viewed = $wpdb->get_results("SELECT DISTINCT $wpdb->posts.*, (meta_value+0) AS views FROM $wpdb->posts LEFT JOIN $wpdb->postmeta ON $wpdb->postmeta.post_id = $wpdb->posts.ID WHERE post_date < '".current_time('mysql')."' AND post_date > '".$limit_date."' AND $where AND post_status = 'publish' AND meta_key = 'views' AND post_password = '' ORDER  BY views DESC LIMIT $limit");
   
           if($most_viewed) {
               $i = 1;
               foreach ($most_viewed as $post) {
                   $title = get_the_title().get_the_subtitle();
                   $post_views = intval($post->views);
                   // $output .= '<li class="item-'.$i.'"><a target="_blank" href="'.get_permalink($postid).'">'._get_post_thumbnail(array()).'<h2>'.$post_title.'</h2><p>'.hui_get_post_date( get_the_time('Y-m-d H:i:s') ).'<span class="post-views">阅读('.$post_views.')</span></p></a></li>';

                   $i++;
               }
           } else {
               $output = '<li>'.__('暂无文章！', 'haoui').'</li>';
           }
   
       }else if( _hui('most_list_style')=='like' ){
   
           global $post;
           $limit_date = current_time('timestamp') - ($days*86400);
           $limit_date = date("Y-m-d H:i:s",$limit_date);
           $where = '';
           $mode = 'post';
   
           if(!empty($mode) && $mode != 'both') {
               $where = "post_type = '$mode'";
           } else {
               $where = '1=1';
           }
   
           $most_viewed = $wpdb->get_results("SELECT DISTINCT $wpdb->posts.*, (meta_value+0) AS `like` FROM $wpdb->posts LEFT JOIN $wpdb->postmeta ON $wpdb->postmeta.post_id = $wpdb->posts.ID WHERE post_date < '".current_time('mysql')."' AND post_date > '".$limit_date."' AND $where AND post_status = 'publish' AND meta_key = 'like' AND post_password = '' ORDER  BY `like` DESC LIMIT $limit");
   
           if($most_viewed) {
               $i = 1;
               foreach ($most_viewed as $post) {
                   $title = get_the_title().get_the_subtitle();
                   $post_likes = intval($post->like);
                   // $output .= '<li class="item-'.$i.'"><a target="_blank" href="'.get_permalink($postid).'">'._get_post_thumbnail(array()).'<h2>'.$post_title.'</h2><p>'.hui_get_post_date( get_the_time('Y-m-d H:i:s') ).'<span class="post-views">阅读('.$post_views.')</span></p></a></li>';
                   $output .= '<li><span class="label label-'.$i.'">'.$i.'</span><a href="'.get_permalink($post->ID).'" title="'.$title.'">'.$title.'</a></li>';
                   $i++;
               }
           } else {
               $output = '<li>'.__('暂无文章！', 'haoui').'</li>';
           }
       }
   
       echo '<div class="most-comment-posts">
               <div class="title"><h3>'._hui('most_list_title').'</h3></div>
               <ul>'.$output.'</ul>
           </div>';
   }

2. 修改 options.php 文件，在文件末尾 return $options; 之前添加以下代码：

   $options[] = array(
   'name' => __('热门排行功能', 'haoui'),
   'type' => 'heading');
   
   $options[] = array(
   'name' => __('热门排行', 'haoui'),
   'id' => 'most_list_s',
   'std' => true,
   'desc' => __('开启', 'haoui'),
   'type' => 'checkbox');
   
   $options[] = array(
   'name' => __('热门排行', 'haoui').$rrr.__('模式', 'haoui').'(v5.3*)',
   'id' => 'most_list_style',
   'std' => "comment",
   'type' => "radio",
   'options' => array(
   'comment' => __('按文章评论数', 'haoui'),
   'view' => __('按文章阅读数', 'haoui'),
   'like' => __('按文章点赞数', 'haoui')
   ));
   
   $options[] = array(
   'name' => __('热门排行', 'haoui').$rrr.__('标题', 'haoui'),
   'id' => 'most_list_title',
   'std' => __('一周热门排行', 'haoui'),
   'type' => 'text');
   
   $options[] = array(
   'name' => __('热门排行', 'haoui').$rrr.__('最近多少天内的文章', 'haoui'),
   'id' => 'most_list_date',
   'std' => 7,
   'class' => 'mini',
   'type' => 'text');
   
   $options[] = array(
   'name' => __('热门排行', 'haoui').$rrr.__('显示数量', 'haoui'),
   'id' => 'most_list_number',
   'std' => 5,
   'class' => 'mini',
   'type' => 'text');

3. 修改 index.php 文件，添加下面的代码至你想要显示热门文章列表的位置即可。

   <!--热门文章排行--> 
   <?php 
   if( _hui('most_list_s') ){
   _moloader('hui_recent_posts_most');
   }
   ?>

4. 添加以下样式到main.css
