ecshop二次开发 之在商品分类页如何增加评论等级和评论数量

注：新手朋友修改时请尽量不要使用记事本进行编辑，最好使用dreamweaver、editplus等专业的代码编辑软件进行编辑

下面是解决办法：

1、
打开 category.php 文件，找到 category_get_goods() 函数部分
将该函数下面的（大概在445行左右） $sql = 'SELECT g.goods_id, g.goods_name,g.goods_name_style, g.market_price, g.is_new, g.is_best, g.is_hot,g.shop_price AS org_price, ' .

               "IFNULL(mp.user_price, g.shop_price * '$_SESSION[discount]') ASshop_price, g.promote_price, g.goods_type, " .

               'g.promote_start_date, g.promote_end_date, g.goods_brief,g.goods_thumb , g.goods_img ' .

           'FROM ' . $GLOBALS['ecs']->table('goods') . ' AS g '.

           'LEFT JOIN ' .$GLOBALS['ecs']->table('member_price') . ' AS mp '.

               "ON mp.goods_id = g.goods_id AND mp.user_rank ='$_SESSION[user_rank]' " .

           "WHERE $where $ext ORDER BY $sort $order";
复制代码修改为

$sql = 'SELECT g.goods_id, g.goods_name, g.goods_name_style,g.market_price, g.is_new, g.is_best, g.is_hot, g.shop_price ASorg_price, ' .
               "IFNULL(mp.user_price, g.shop_price * '$_SESSION[discount]') ASshop_price, g.promote_price, g.goods_type, " .
  " IFNULL(AVG(r.comment_rank),0) AScomment_rank,IF(r.comment_rank,count(*),0)AS  comment_count, ".
               'g.promote_start_date, g.promote_end_date, g.goods_brief,g.goods_thumb , g.goods_img ' .
           'FROM ' . $GLOBALS['ecs']->table('goods') . ' AS g '.
           'LEFT JOIN ' .$GLOBALS['ecs']->table('member_price') . ' AS mp '.
               "ON mp.goods_id = g.goods_id AND mp.user_rank ='$_SESSION[user_rank]' " .
    ' LEFT JOIN  '.$GLOBALS['ecs']->table('comment') .' AS r '.
   'ON r.id_value =g.goods_id AND comment_type = 0 AND r.parent_id = 0 AND r.status =1 ' .
           "WHERE $where $ext group by g.goods_id ORDER BY $sort $order";

（红色部分为新增加的代码）
然后继续找到$arr[$row['goods_id']]['url']             = build_uri('goods', array('gid'=>$row['goods_id']),$row['goods_name']);
复制代码在这行代码下面增加 $row['comment_rank']  =ceil($row['comment_rank']) == 0 ? 5 :ceil($row['comment_rank']);

$arr[$row['goods_id']]['comment_rank']=$row['comment_rank'];

$arr[$row['goods_id']]['comment_count']=$row['comment_count'];
复制代码2、
打开 library/goods_list.lbi 文件
在
<a href="javascript:collect({$goods.goods_id});"class="f6">{$lang.btn_collect}</a>
上面增加
<imgsrc="images/stars{$goods.comment_rank}.gif" style="width:78px;height:15px;"/><br> 
评论数：{$goods.comment_count}<br>

3、
建议继续把 category.php 文件的
$smarty->caching = true;
修改为
$smarty->caching = false;
这样就能即时体现评论等级和评论数量的变化了，要不还得经常到后台“清除缓存”
