为什么有的代码不执行？

legendnan 2016-10-17 02:16:20

整段代码如下， $log_sql 和$user_sql 都能存到数据库中，但是$order_sql却不执行。不知道什么道理呢？
求大神分析下，我自己测试的时候每次都是成功的，但是到用户那里就会失败！



public function get_code($order, $config_value){



        $res = D('order')->where('master_order_sn = '.$order['master_order_sn'])->select();

        $num = 1;

        foreach ($res as $k=>$v){

            $num += $k;

        }

        if ($num >1){

            foreach ($res as $kk => $vv){

                $data['user_id'] =$vv['user_id'];

                $data['pay_points'] = $data['user_money'] = '-'.$vv['order_amount'];

                $data['change_time'] = time();

                $data['desc'] = '下单消费';

                $data['order_sn'] = $vv['order_sn'];

                $data['order_id'] = $vv['order_id'];

                $save_data = array('pay_status'=>1,'user_money'=>$vv['order_amount'],'pay_code '=>'balance','pay_name'=>'余额支付','pay_time'=>time());

                $order_sql = D('order')->where('order_sn = '.$vv['order_sn'])->setField($save_data);

                $log_sql = D('account_log')->add($data);

                $user_sql = D('users')->where('user_id = '.$vv['user_id'])->setDec('user_money',$vv['order_amount']);

                /*echo $order_sql;

                echo "<br/>";

                echo $log_sql;

                echo "<br/>";

                echo $user_sql;1c5d3018

                echo "<br/>";*/

            }

        }else{

            $data['user_id'] = $order['user_id'];

            $user_id = $order['user_id'];

            $user_sql =D('users')->where('user_id = '.$user_id)->setDec('user_money',$order['order_amount']);

        }

        



        if ($order_sql && $log_sql && $user_sql ){

            return true;

        }else{

            return false;

        }
