ecshop在商品列表显示购买记录

遇到这样的需求不用自己写代码，很多都是官方写好的，商品详细页本来就有个购买记录，我们打开goods.php就会看到

 

------------------------------------------------------------------------------------------------------------------------

      $sql = 'SELECT count(*) ' .

               'FROM ' . $ecs->table('order_info') . ' AS oi LEFT JOIN ' . $ecs->table('users') . ' AS u ON oi.user_id = u.user_id, ' . $ecs->table('order_goods') . ' AS og ' .

               'WHERE oi.order_id = og.order_id AND ' . time() . ' - oi.add_time < 2592000 AND og.goods_id = ' . $goods_id;

        $count = $db->getOne($sql);

 

------------------------------------------------------------------------------------------------------------------------

 

这时候我们修改一下 写成一个函数放到lib_goods.php 这样就可以随便调用了

 

------------------------------------------------------------------------------------------------------------------------

/**获得购买次数*/

function get_goods_ordernum($goods_id)

{

 

        $sql = 'SELECT count(*) ' .

               'FROM ' . $GLOBALS['ecs']->table('order_info') . ' AS oi LEFT JOIN ' . $GLOBALS['ecs']->table('users') . ' AS u ON oi.user_id = u.user_id, ' . $GLOBALS['ecs']->table('order_goods') . ' AS

og ' .

               'WHERE oi.order_id = og.order_id AND ' . time() . ' - oi.add_time < 2592000 AND og.goods_id = ' . $goods_id;

        $count = $GLOBALS['db']->getOne($sql);

  return $count;

 

}

 

------------------------------------------------------------------------------------------------------------------------

函数写好我们下来开始调用。比如我们在最新商品下显示购买记录

在lib_goods.php找到get_recommend_goods这个函数 342行左右加入

 

 

$goods[$idx]['order_num']    = get_goods_ordernum($row['goods_id']);

 

 

 

到此程序部分完成

 

-----------------------------------------------------------------------------------------------------------------------------

 

 

 

模板部分是：<span style="color:#0066FF;">{if $goods.order_num}已经有{$goods.order_num}人购买过{else}暂无人购买{/if}</span>
