更新：

    Error Number: 42S22/1054

Unknown column 'Array' in 'field list'

INSERT INTO `attendance` (`event_date`, `event_time`, `event_info`, `player_id`, `is_present`, `notes`) VALUES ('2017-03-08', '11:00:00 AM', 'other', NULL, Array, 'notes')

＆＃39; NULL＆＃39;应该是＆＃39; player_id＆＃39;和＆＃39;阵列＆＃39;应该存在或不存在。非常坚持这一点，所以感谢你们所有的帮助，到目前为止，我真的很感激。

我试图创建一个出勤表，该表可以保存一个人的身份，然后有两列 - 1表示现在，另一列表示缺席。所以我会一次性向数据库中添加多行。

我刚从视图中添加了代码，因为我知道我的控制器和模型很好，因为其他输入字段工作正常。

对于每一行，我希望它输入player_id以及它们是present还是absent。在我的数据库中，is_present为enum yes或no。我知道这可能没有接近正确的地方，所以感谢任何建议。

控制器

function add_attendance(){

    $event_date=$this->input->post('event_date');
    $event_time=$this->input->post('event_time');
    $event_info=$this->input->post('event_info');
    $player_id=$this->input->post('player_id');
    $is_present=$this->input->post('attendance');
    $notes=$this->input->post('notes');


    $data = array(
        'event_date'=>$event_date,
        'event_time'=>$event_time,
        'event_info'=>$event_info,
        'player_id'=>$player_id,
        'is_present'=>$is_present,
        'notes'=>$notes

);

Answer 1

<table class="table table-sm table-bordered tabular_datable-condensed table-hover" id="playertable" name="player_id">

请删除表格name=player_id？

以下为视图

示例

<table>
    <thead>
        <tr>
            <th>Player ID</th>
            <th>Player name</th>
            <th>Attending</th>
        </tr>
    </thead>
    <tbody>
        <?php foreach($query->result_array() as $row) : ?>
        <tr>
            <!-- hidden input for player_id -->
            <?php echo form_hidden('player_id[' .$row["player_id"]. ']', $row['player_id']); ?>
            <!-- /hidden input for player_id -->
            <td><?php echo $row['player_id']; ?></td>
            <td><?php echo $row['player_name']; ?></td>
            <td>
                <label>
                    <input type="radio" name="attendance[<?php echo $row['player_id']; ?>]" value="Yes" <?php echo set_radio('attendance', 'Yes', TRUE); ?> >Present
                </label>
                <label>
                    <input type="radio" name="attendance[<?php echo $row['player_id']; ?>]" value="No" <?php echo set_radio('attendance', 'No'); ?> >Absent
                </label>
            </td>
        </tr>
        <?php endforeach; ?>
    </tbody>
</table>

提交后，会发布多个阵列

<强>控制器

public function add()
{
    $player_id = $this->input->post('player_id');
    $is_present = $this->input->post('attendance');

    $i=1;
    $data = array();

    // formating array posts
    foreach ($player_id as $k => $val) {
        $data[] = array('player_id' => $val, 'is_present' => $is_present[$i]);
        $i++;
    }

    echo var_dump($data);
}

这里输出的帖子是：

array(3) {
  [0]=>
  array(2) {
    ["player_id"]=>
    string(1) "1"
    ["is_present"]=>
    string(3) "Yes"
  }
  [1]=>
  array(2) {
    ["player_id"]=>
    string(1) "2"
    ["is_present"]=>
    string(2) "No"
  }
  [2]=>
  array(2) {
    ["player_id"]=>
    string(1) "3"
    ["is_present"]=>
    string(3) "Yes"
  }
}

接下来，multiple insert

的模型调用$this->db->insert_batch()

Answer 2

修正输入

 <label>
 <input type="radio" name="attendance<?php echo $row['player_id']; ?>" 
 value="yes"<?php if (isset($attendance) && $attendance=="yes") 
 echo "checked";?>  > Present
 </label>

Answer 3

检查使用echo "<pre>"; print_r($this->input->post()); exit;向控制器发布的输入是什么，然后找到输入问题的最新信息。同时从单选按钮中删除阵列。
