" 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') ."
