ecshop首页：这个需要修改一个程序文件 lib_goods.php
实现在文件末尾添加一个函数

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);
  }

然后找到在get_recommend_goods函数中大致325行

$goods[$idx]['url']  = build_uri('goods', array('gid' => $row['goods_id']), $row['goods_name']);

其后添加

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

剩下的就是通过在模板中用

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

调用了
ECSHOP商品分类页：
修改 category.php 文件
在

$arr[$row['goods_id']]['goods_id']  = $row['goods_id'];

下增加

$sql="selectNULL(goods_number),0) from ". $GLOBALS['ecs']->table('order_goods') . " AS og , ". $GLOBALS['ecs']->table('order_info') ." AS o where o.order_id =og.order_id and o.order_status >0 and og.goods_id=".$row['goods_id'];
$arr[$row['goods_id']]['count_sell']=$GLOBALS['db']->getOne($sql);
