代码如下:

$smarty->assign('goods_count', get_goods_coun($goods_id)); ，

最后在模板文件goods.dwt中 {$goods_count} 直接调用就行了。

复制代码

代码如下:

/**
* 获取商品出售总数
*
* @access public
* @param integer $goods_id
* @return integer
*/
function get_goods_count($goods_id)
{


$sql = 'SELECT IFNULL(SUM(g.goods_number), 0) ' .
'FROM ' . $GLOBALS['ecs']->table('order_info') . 'AS o, ' .
$GLOBALS['ecs']->table('order_goods') . 'AS g ' .
"WHERE o.order_id = g.order_id " .
"AND o.order_status = '" . OS_CONFIRMED . "'" .
"AND o.shipping_status " . db_create_in(array(SS_SHIPPED, SS_RECEIVED)) .
" AND o.pay_status " . db_create_in(array(PS_PAYED, PS_PAYING)) .
" AND g.goods_id = '$goods_id'";
$sales_count = $GLOBALS['db']->getOne($sql);
return $sales_count;
}
