在ECSHOP的商品列表调用评论数量的方法

ECSHOP的商品列表页如果能显示相对应的评论数，那就更好了，我们也可以添加一些浏览次数，这样商品的列表看起来就更加丰富了，今天我们就给大家来讲解一下如何在ECSHOP的商品列表调用评论数量，需要修改系统文件，修改之前请备份相关文件。

修改分类文件

修改category.php 文件，定位到 category_get_goods() 函数部分找到

SQL Code 复制内容到剪贴板

$sql = 'SELECT g.goods_id, g.goods_name, g.goods_name_style, g.market_price, g.is_new, g.is_best, g.is_hot, g.shop_price AS org_price, ' .
                "IFNULL(mp.user_price, g.shop_price * '$_SESSION[discount]') AS shop_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";

修改为

SQL Code 复制内容到剪贴板

$sql = 'SELECT g.goods_id, g.goods_name, g.goods_name_style, g.market_price, g.is_new, g.is_best, g.is_hot, g.shop_price AS org_price, ' .
                "IFNULL(mp.user_price, g.shop_price * '$_SESSION[discount]') AS shop_price, g.promote_price, g.goods_type, " .
  " IFNULL(AVG(r.comment_rank),0) AS comment_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";

然后继续找到

复制代码

代码如下:

$arr[$row['goods_id']]['url'] = build_uri('goods', array('gid'=>$row['goods_id']), $row['goods_name']);

在它下面增加几行代码

复制代码

代码如下:

$row['comment_rank'] = ceil($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'];

修改模版文件

修改 themes/default/library/goods_list.lbi 文件找到

复制代码

代码如下:

{$lang.btn_collect}

在它上面增加

复制代码

代码如下:

评论数：{$goods.comment_count}

PS：大家都知道ECSHOP系统有缓存机制，如果某个商品有了新的评论，列表页的评论数量不会立马随着更新。得等到下次更新缓存的时候才会更新。

如果您想列表页能即时体现评论数量的变化。只需继续进行下面修改即可。

把 category.php 文件的

$smarty->caching = true;

修改为

$smarty->caching = false;
