ecshop教程：显示某商品销售累计效果的实现代码
方案如下：修改 includes/lib_insert.php 文件，
增加一个函数
复制代码代码如下:
/**
* 调用某商品的累积售出
*/
function insert_goods_sells($arr)
{
$sql = 'SELECT SUM(goods_number) AS number ' .
' FROM ' . $GLOBALS['ecs',->table('order_goods') ." AS og , " . $GLOBALS['ecs',->table('order_info') ." AS o ".
" WHERE og.order_id = o.order_id and og.goods_id=".$arr['goods_id',;
$row = $GLOBALS['db',->GetRow($sql);
if ($row)
{
$number = intval($row['number',);
}
else
{
$number = 0;
}
return $number;
}
修改模板下goods.dwt文件
增加一行代码
累计售出：{insert name='goods_sells' goods_id=$id}{$goods.measure_unit}
