PHP:在foreach中保存foreach数据

Question

我正在尝试通过这些模型保存数据集。

模型 1：服务

生成一系列服务日期。

模型 2：响应

对于每个服务条目，用户需要添加一定数量的响应。

因此，我想为多个响应保存多个服务条目。 该代码相当不言自明，但如果需要，我可以添加更多信息。 我找不到一个简单的解决方案来做到这一点，尽管我觉得这相当简单。

    if (isset($_POST['Service'], $_POST['Response']))
    {
        $model->attributes = $_POST['Service'];
        $valid = $model->validate();
        // date manipulation
        $start = new DateTime($model->date_booked);
        $start->format('Y-m-d');
        $end = new DateTime($model->end_date);
        $end->format('Y-m-d');
        $interval = DateInterval::createFromDateString($model->interval);
        $range = new DatePeriod($start, $interval, $end);
        if ($valid)
        {
            foreach ($range as $key => $value)
            {
                $schedule = new Service;
                $schedule->attributes = $_POST['Service'];
                $schedule->date_booked = $value->format('Y-m-d');
                // If I were to save here, the following, Response Model
                // will not be validated!
                // $schedule->save(); 

                foreach ($_POST['Response'] as $j => $k)
                {
                        $response[$j] = new Response;
                        $response[$j]->attributes = $_POST['Response'][$j];
                        // If I were to save the Service Models here, 
                        // evidently, entries are doubled up!
                        // $service->save();
                        $response[$j]->service_id = $service->id;
                        $valid = $response[$j]->validate() && $valid;
                        // $response[$j]->save();

                }
            }
        }
    }

谢谢！

我必须运行另一个 foreach 循环才能让它工作。 是的，我确实觉得我正在迭代循环，所以如果有人有另一个优雅的解决方案，请务必将它们分享给我。:-)

目前，这已经完成。

    if (isset($_POST['Service'], $_POST['Response']))
    {
        // Assign and validate Service mcrypt_module_is_block_algorithm
        $model->attributes = $_POST['Service'];
        $valid = $model->validate();
        // date manipulation
        $start = new DateTime($model->date_booked);
        $start->format('Y-m-d');
        $end = new DateTime($model->end_date);
        $end->format('Y-m-d');
        $interval = DateInterval::createFromDateString($model->interval);
        $range = new DatePeriod($start, $interval, $end);
        // Assign and Validate Response Populated questions
        foreach ($_POST['Response'] as $j => $k)
        {
                $response[$j] = new Response('populate'); // populate scenario
                $response[$j]->attributes = $_POST['Response'][$j];
                $valid = $response[$j]->validate() && $valid;
        }
        if ($valid)
        {
            foreach ($range as $key => $value)
            {
                $schedule = new Service; // static model
                $schedule->attributes = $_POST['Service'];
                $schedule->date_booked = $value->format('Y-m-d');
                $schedule->save();
                foreach ($_POST['Response'] as $x => $y)
                {
                        $response[$x] = new Response('populate'); // populate scenario
                        $response[$x]->attributes = $_POST['Response'][$x];
                        $response[$x]->service_id = $schedule->id;
                        $response[$x]->save();
                }
            }
        }
    }
