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
[html] view plaincopy
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);
}
然后往上找到317行左右, 找到
[html] view plaincopy
$goods[$idx]['brand_name'] = isset($goods_data['brand'][$row['goods_id']]) ? $goods_data['brand'][$row['goods_id']] : '';
在它下面添加
[html] view plaincopy
$goods[$idx]['buy_num']= get_buy_sum($row['goods_id']);
最后就是通过在模板文件中调用了,如下这般调用
[html] view plaincopy
{if $goods.buy_num}
{$goods.buy_num}
{else}
0
{/if}
