问题:想在首页每个商品下显示“已销售XX个”,该如何操作呢?

教程:
第1步:打开文件  includes/lib_goods.php
在该文件的末尾添加如下代码片段

function get_buy_sum($goods_id)

{

$sql = "select sum(goods_number) from " . $GLOBALS['ecs']->table('order_goods') . " AS g ,".$GLOBALS['ecs']->table('order_info') . " AS o WHERE o.order_id=g.order_id and g.goods_id = " . $goods_id . "  and o.order_status=1 "  ;//o.order_status=1 表示确认了的订单才算

    return $GLOBALS['db']->getOne($sql);

}


然后往上找到317行左右, 找到
$goods[$idx]['brand_name']   = isset($goods_data['brand'][$row['goods_id']]) ? $goods_data['brand'][$row['goods_id']] : '';

在它下面添加
$goods[$idx]['buy_num']= get_buy_sum($row['goods_id']);

最后就是通过在文件中调用了,如下这般调用

{if $goods.buy_num}
{$goods.buy_num}
{else}
0
{/if}
