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>
