首先找到程序文件 lib_goods.php，在文件末尾添加一个函数:

[code lang="php"]
function get_evaluation_sum($goods_id)
{
$sql = "SELECT count(*) FROM " . $GLOBALS['ecs']->table('comment') . " WHERE status=1 and comment_type =0 and id_value =".$goods_id ;//status=1表示通过了的评论才算 comment_type =0表示针对商品的评价
return $GLOBALS['db']->getOne($sql);
}
[/code]

然后找到 在get_recommend_goods函数中 大致325行

[code lang="php"]
$goods[$idx]['url'] = build_uri('goods', array('gid' => $row['goods_id']), $row['goods_name']);
[/code]

其后添加:

[code lang="php"]
$goods[$idx]['evaluation'] = get_evaluation_sum($row['goods_id']);
[/code]

剩下的就是通过在模板中 用{$goods.evaluation}调用了,如果分类下面商品也要显示已评论数量,在lib_goods.php程序中所有的:

[code lang="php"]
$goods[$idx]['url'] = build_uri('goods', array('gid' => $row['goods_id']), $row['goods_name']);
[/code]

代码后添加：

[code lang="php"]
$goods[$idx]['evaluation'] = get_evaluation_sum($row['goods_id']);
[/code]

这样就可以在首页显示出评论数量啦！
