获取点击人气排行榜

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
*/
