在ECSHOP商品列表页显示每个商品的评论等级和评论数量
问题描述：
我想让商品列表页（category.php）的每个商品的下面显示该商品的评论数量以及评论等级，该如何操作呢？？
效果图示：
解决方法：
第一步：
首先修改category.php 文件，定位到 category_get_goods() 函数部分
找到
$sql = 'SELECT g.goods_id, g.goods_name, g.goods_name_style, g.market_price, g.is_new, g.is_best, g.is_hot, g.shop_price AS org_price, ' . "IFNULL(mp.user_price, g.shop_price * '$_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";
将之修改为
$sql = 'SELECT g.goods_id, g.goods_name, g.goods_name_style, g.market_price, g.is_new, g.is_best, g.is_hot, g.shop_price AS org_price, ' . "IFNULL(mp.user_price, g.shop_price * '$_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
$arr[$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
$row['comment_rank'] = ceil($row['comment_rank']) == 0 ? 5 : ceil($row['comment_rank']); $arr[$row['goods_id']]['comment_rank']=$row['comment_rank']; $arr[$row['goods_id']]['comment_count']=$row['comment_count'];
第二步(以官方默认模板为例)：
修改 htemes/default/library/goods_list.lbi 文件
找到
<a href="javascript:collect({$goods.goods_id});" class="f6">{$lang.btn_collect}</a>
在它上面增加
<img src="images/stars{$goods.comment_rank}.gif" style="width:78px;height:15px;" /><br>
评论数：{$goods.comment_count}<br>
结束语：
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;
