1、这里说的商品简单描述，不是商品的详细信息，而是后台编辑商品时在“其他信息”标签栏填写的那个“商品简单描述”，即goods_brief字段
2、修改lib_order.php文件的get_cart_goods()函数部分
将
$goods_thumb = $GLOBALS['db']->getOne("SELECT `goods_thumb` FROM " . $GLOBALS['ecs']->table('goods') . " WHERE `goods_id`='{$row['goods_id']}'");
$row['goods_thumb'] = get_image_path($row['goods_id'], $goods_thumb, true);
修改为
$goods_thumb = $GLOBALS['db']->getRow("SELECT `goods_thumb`,`goods_brief` FROM " . $GLOBALS['ecs']->table('goods') . " WHERE `goods_id`='{$row['goods_id']}'");
$row['goods_thumb'] = get_image_path($row['goods_id'], $goods_thumb['goods_thumb'], true);
$row['goods_brief']=$goods_thumb['goods_brief'];
3、在文件(flow.dwt)合适位置调用即可：
   {$goods.goods_brief}
