ECSHOP首页每个商品下显示已销售量

一、打开文件 includes/lib_goods.php  在该文件的末尾添加如下代码

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   ;

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

}

再继续，查找

$goods[$idx]['brand_name']   = isset($goods_data['brand'][$row['goods_id']]) ? $goods_data['brand'][$row['goods_id']] : '';

在下面添加代码

$goods[$idx]['buy_num']= get_buy_sum($row['goods_id']);

二、模板文件中调用，如下代码

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