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}
