如何在 Codeigniter 的数据库中插入一个数组？

Question

我在 Codeigniter 的数据库中插入数组时遇到问题，我尝试了以下方法但它给出了错误“消息：非法字符串偏移量 'year'”、“消息：非法字符串偏移量 'month'”等等...，我真的很困惑如何解决这个问题，请帮忙。

这是表格：

<form action="<?php echo base_url();?>hr/Home/store_attendance" method="post"
id="student_attendance_entry">
<input type="hidden" name="year" value="<?php echo $year; ?>" />
<input type="hidden" name="month" value="<?php echo $month; ?>" />
<?php foreach($staffs as $staff): ?>
<table class="table table-striped table-bordered table-hover attendance_entry"
    style="border:initial;border: 1px solid #ddd;" id="sample_editable_2">
    <thead>
        <tr>
            <th style="width: 50px !important;">شماره</th>
            <th align="center" style="width:auto%">آی دی</th>
            <th align="center" style="width:15%">نام</th>
            <th align="center" style="width:15%;"> ولد</th>
            <th align="center" style="width:auto">حاضر</th>
            <th align="center" style="width:auto">غیر حاضر</th>
            <th align="center" style="width:auto">توضیحات</th>
        </tr>
    </thead>
    <tbody>
        <?php $a=1; foreach($staffs as $st):?>
        <tr>
            <td align="center" style="font-size: 11px"><?php echo $a;?></td>
            <td align="center" style="font-size: 11px"><?php echo $st['s_id'];?></td>
            <td align="center"><?php echo $st['dari_name'];?></td>
            <td align="center"><?php echo $st['dari_fName'];?></td>
            <td>
                <input type="number" min="0" class="form-control" name="total_present_day[]"
                    value="<?php if($st['total_present']==null){echo '';}else{ echo $st['total_present'];}?>"
                    data="<?php echo $a;?>">

                <input type="hidden" name="salary_type[]" id="salary_type" value="<?php echo $st['salary_type']?>">
            </td>
            <td>
                <input type="number" min="0" class="form-control" name="total_absent_day[]"
                    value="<?php if($st['absent']==null){echo '';}else{ echo $st['absent'];}?>"
                    data="<?php echo $a;?>">
                <input type="hidden" class="form-control" name="staff_id[]" value="<?php echo $st['s_id'];?>">

            </td>
            <td>
                <textarea min="0" class="form-control" name="memo[]"
                    colspan='3' rowspan="1"
                    data="<?php echo $a;?>"><?php if($st['memo']==null){echo '';}else{ echo $st['memo'];}?></textarea>
               

            </td>
        </tr>
        <?php $a++;endforeach;?>
    </tbody>
</table>

<?php endforeach; ?>
<br>
<div class="form-actions right">
    <a href="<?php echo base_url();?>student/school/attendance" class="btn default" data-dismiss="modal"><i
            class="fa fa-close"></i> بستن</a>
    <input type="submit" name="save" class="btn blue" value="ذخیره" />
</div>

这是控制器：

 public function store_attendance()
{
    $data=array(

        'year' =>  $this->input->post('year'),
        'month' => $this->input->post('month'),
        'staff_id' => $this->input->post('staff_id'),
        'total_present_day' => $this->input->post('total_present_day'),
        'total_absent_day'=>$this->input->post('total_absent_day'),
        'salary_type'=>$this->input->post('salary_type'),
        'memo'=>$this->input->post('memo')
    );
    $this->dd($data);
    // $this->dd($class);
    $insert_att = $this->stuff_model->add_staff_attendance($data);
    // var_dump($insert_att);
    if($insert_att)
    {
        echo redirect(base_url().'hr/register_employee_attendance');
    }
   
}

这是型号：

public function add_staff_attendance($data)
  {
      $this->db->trans_begin();

      foreach ($data['total_present_day'] as $key => $value) {
          {
          
  $dataToSave = array(
   'year' =>  $value['year'],
   'month' => $value['month'],
   'type_id'=>$value['salary_type'][$key],
   'total_present' => $value['total_present_day'][$key],
   'absent'=>$value['total_absent_day'][$key],
   'memo'=>$value['memo'][$key],
   'staf_id' => $value['staff_id'][$key]
 );
      
        $this->db->insert('staff_attendance', $dataToSave);
    }
          if ($this->db->trans_status() === false) {
              $this->db->trans_rollback();
              return false;
          } else {
              $this->db->trans_commit();
              return true;
          }
      }
}

我在控制器中调用了 $this->dd($data)，这是输出：

array (
'Total' => 7,
)
array (
  'year' => '1400',
  'month' => '2',
  'staff_id' => 
     array (
       0 => '3',
     ),
   'total_present_day' => 
     array (
       0 => '26',
   ),
   'total_absent_day' => 
      array (
        0 => '0',
      ),
   'salary_type' => '1',
   'memo' => 
    array (
      0 => 'dds',
    ),
)

这是 echo '<pre>'; print_r($data); echo '</pre>'; 在模型中的结果：

 Array
 (
   [year] => 1400
   [month] => 1
   [staff_id] => Array
     (
       [0] => 3
       [1] => 1
     )

[total_present_day] => Array
    (
        [0] => 26
        [1] => 20
    )

[total_absent_day] => Array
    (
        [0] => 0
        [1] => 6
    )

[salary_type] => Array
    (
        [0] => 1
        [1] => 1
    )

[memo] => Array
    (
        [0] => asfd
        [1] => saef
    )

    )
    Array
    (
    [year] => 1400
    [month] => 1

好像是controller的错误，保存的时候一定要遍历array

public function store_attendance()
{
    $data=array(

        'year' =>  $this->input->post('year'),
        'month' => $this->input->post('month'),
        'staff_id' => $this->input->post('staff_id'),
        'total_present_day' => $this->input->post('total_present_day'),
        'total_absent_day'=>$this->input->post('total_absent_day'),
        'salary_type'=>$this->input->post('salary_type'),
        'memo'=>$this->input->post('memo')
    );
    foreach($data as $d):
   
    $insert_att = $this->stuff_model->add_staff_attendance($d);
    
    if($insert_att)
    {
        echo redirect(base_url().'hr/register_employee_attendance');
    }
    else
    {
        echo redirect(base_url().'hr/register_employee_attendance');
    }
    endforeach;
}

你应该尝试类似的东西

Answer 3

您提交的数据结构合理、简约但不规则。通过重新配置视图中表单字段的 name 属性，可以大大减少控制器和模型中的处理代码行。

将隐藏字段移到 foeach() 循环中并声明动态索引。实际上，命名字段类似于：

<?php foreach($staffs as $index => $staff) { ?>
    <input type="hidden" name="attendance[<?php echo $index; ?>]['year']">
    <input type="hidden" name="attendance[<?php echo $index; ?>]['month']">
    <input type="number" name="attendance[<?php echo $index; ?>]['total_present']">
    <input type="hidden" name="attendance[<?php echo $index; ?>]['type_id']">
    <input type="number" name="attendance[<?php echo $index; ?>]['absent']">
    <input type="hidden" name="attendance[<?php echo $index; ?>]['staf_id']">
    <textarea name="attendance[<?php echo $index; ?>]['memo']"></textarea>
<?php } ?>

在盲目地将数据传递给模型之前，控制器需要一个 validation/sanitization 过程和一些重组。我不会深入 validation/sanitization，但您应该迭代数据，如果任何值不合适，则拒绝保存它。

控制器：

public function store_attendance(): void
{
    // Definitely validate and sanitize the rows of data before passing to model.
    // This shortcut is for demonstrating how to batch insert
    if ($this->stuff_model->add_staff_attendance($this->input->post('attendance'))) {
        redirect(base_url() . 'hr/home/register_employee_attendance');
    } else {
        // reload view and explain what went wrong
    }
}

型号：

public function add_staff_attendance(array $data): bool
{
    return $this->db->insert_batch('staff_attendance', $data);
}

None 这个答案已经过测试。

要将隐藏字段保留在循环之外，您需要 assemble 行的值在发送到 batch_insertion 模型之前进入正确的结构。

$presentDays = $this->input->post('total_present_day');
if ($presentDay) {
    $rows = [];
    foreach ($presentDays as $i => $presentDay) {
        $rows[] = [
            'year' => $this->input->post('year'),
            'month' => $this->input->post('month'),
            'staf_id' => $this->input->post('staff_id')[$i],
            'total_present' => $this->input->post('total_present_day')[$i],
            'absent' => $this->input->post('total_absent_day')[$i],
            'type_id' => $this->input->post('salary_type')[$i],
            'memo' => $this->input->post('memo')[$i]
        ];
    }
    
    if ($this->stuff_model->add_staff_attendance($rows)) {
        redirect(base_url() . 'hr/home/register_employee_attendance');
    } else {
        // reload view and explain what went wrong
    }
}

我通过更改控制器和模型中的一些代码解决了我的问题。控制器：

public function store_attendance()
{   
    $data = array();
    $insert_att = 0;
    $tst = $this->input->post('total_present_day');

    for ($i=0; $i < count($tst); $i++) {
      
        $data = array(
            'year' =>  $this->input->post('year'),
            'month' => $this->input->post('month'),
            'staf_id' => $this->input->post('staff_id')[$i],
            'total_present' => $this->input->post('total_present_day')[$i],
            'absent'=>$this->input->post('total_absent_day')[$i],
            'type_id'=>$this->input->post('salary_type')[$i],
            'memo'=>$this->input->post('memo')[$i],
        );
        // var_dump($data);
        
        $this->get_public_data->saveData('staff_attendance', $data);
        
    }

    echo redirect(base_url().'hr/home/rgisterAttendance');
}

型号：

 public function add_staff_attendance($data)
  {
  $this->db->insert('staff_attendance', $data);      
}
