[教程] ECSHOP首页商品显示购买次数的实现方法

这个需要修改一个程序文件 lib_goods.php 

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}
