codeigniter 中棘手的关联数组插入

Question

我的table看起来像这样

+---------+-------------+----------+
|  day    | start_time  | end_time |
+---------+-------------+----------+
|  monday | 10:00:00    | 12:00:00 |
+---------+-------------+----------+

我从表单中获取的关联数组如下所示

  [timeslot] => Array
        (
            [1] => Array
                (
                    [weekday] => 1
                    [from] => Array
                        (
                            [0] => 1:15 PM
                            [1] => 4:15 PM
                        )

                    [to] => Array
                        (
                            [0] => 2:15 PM
                            [1] => 5:15 PM
                        )

                )

            [2] => Array
                (
                    [weekday] => 2
                    [from] => Array
                        (
                            [0] => 
                        )

                    [to] => Array
                        (
                            [0] => 
                        )

                )

            [3] => Array
                (
                    [weekday] => 3
                    [from] => Array
                        (
                            [0] => 
                        )

                    [to] => Array
                        (
                            [0] => 
                        )

                )

            [4] => Array
                (
                    [weekday] => 4
                    [from] => Array
                        (
                            [0] => 
                        )

                    [to] => Array
                        (
                            [0] => 
                        )

                )

            [5] => Array
                (
                    [weekday] => 5
                    [from] => Array
                        (
                            [0] => 
                        )

                    [to] => Array
                        (
                            [0] => 
                        )

                )

            [6] => Array
                (
                    [weekday] => 6
                    [from] => Array
                        (
                            [0] => 
                        )

                    [to] => Array
                        (
                            [0] => 
                        )

                )

            [7] => Array
                (
                    [weekday] => 7
                    [from] => Array
                        (
                            [0] => 1:15 PM
                        )

                    [to] => Array
                        (
                            [0] => 3:15 PM
                        )

                )

        )

Codeigniter 中的普通数组插入不适用于此。解决这个问题的任何方法。

我需要这样存储

+---------+-------------+----------+
|  day    | start_time  | end_time |
+---------+-------------+----------+
|  monday | 12:30:00    | 01:30:00 |
|  monday | 04:30:00    | 06:30:00 |
+---------+-------------+----------+

我尝试使用

插入它

$this->db->insert('time_slots', $data);

但这是我所拥有的关联格式的失败。

如果 from 和 to 是数组，我还想遍历 我的数组

并使用上述命令插入数据，但我怀疑是性能问题。

Answer 1

像这样创建数组并传递给模型

  $weekDay = array('1'=>'Sunday','2'=>'Monday','3'=>'Tuesday','4'=>'Wednesday','5'=>'Thurday','6'=>'Friday','7'=>'Saturday');
    foreach($_POST['timeslot'] as $key=>$val){
        foreach($val['from'] as $k=>$v){
            $day = $val['weekday'];
            $data[] = array(
                    'day'=>$weekDay[$day],
                    'start_time'=>$v['from'],
                    'end_time'=>$val['to'][$k]
            );
        }
    }


$this->db->insert_batch('time_slots', $data); 

Answer 2

像这样工作

        foreach ($_POST['timeslot'] as $key => $val) {

                switch($val['weekday']){
                    case 1:
                    $val['day']='monday';
                    break;
                    case 2:
                    $val['day']='tuesday';
                    break;
                    case 3:
                    $val['day']='wednesday';
                    break;
                    case 4:
                    $val['day']='thursday';
                    break;
                    case 5:
                    $val['day']='friday';
                    break;
                    case 6:
                    $val['day']='saturday';
                    break;
                    case 7:
                    $val['day']='sunday';
                    break;
                }
            if(count(array_filter($val['from']))>0){

                foreach($val['from'] as $k=>$v){
                    $tmp= array(
                            'day'=>$val['day'],
                            'start_time'=>$v,
                            'end_time'=>$val['to'][$k]
                    );

                    array_push($slots,$tmp);
                }
            }

        }

依靠 $val['from'] 像这样 count(array_filter($val['from'])) 删除 null 和空数组。
