主要修改两部分。index.php和lib_goods.php
 关于涉及到index.dwt的，请将按销量排行的改为from = top_hots_all
  index.php增加
 $smarty->assign('top_hots_all',       get_top10_hot(0));           // 全部人气排行
 /**
 lib_goods.php lib库增加函数（children取得子类产品id）
 * 调用当前人气排行榜
 *按点击排列 i<10 显示10个
 * @access  public
 * @param   string  $cats   查询的分类
 * @return  array
 */
 function get_top10_hot($cats)
 {
 if (empty($cats))
 {
   $children = '';
 }
    else 
{
     $children =  "WHERE ".get_children($cats);
 }
   $sql = 'SELECT * ' .
             ' FROM ' . $GLOBALS['ecs']->table('goods') .' g '.
             "  $children" .
             ' ORDER BY click_count DESC LIMIT 0 , 10';
 
    $hot = $GLOBALS['db']->getALL($sql);
 
    for ($i = 0; $i < 10; $i++)
     {
         $hot[$i]['short_name'] = $GLOBALS['_CFG']['goods_name_length'] > 0 ?
                                     sub_str($hot[$i]['goods_name'], $GLOBALS['_CFG']['goods_name_length']) : $hot[$i]['goods_name'];/*$hot[$i]['goods_name'];*/
         $hot[$i]['url']        = build_uri('goods', array('gid' => $hot[$i]['goods_id']), $hot[$i]['goods_name']);
   $hot[$i]['name'] = $hot[$i]['goods_name'];
 
    }
     return $hot;
 }
 这样就可以调用了。
