Question

我需要从数据库中检索显示值的td标记中携带的值，然后将它们插入到不同的数据库中。我从模型中检索了两个值seateat和seatLabel，并在带有seatNumber值的checkboxex中显示它们。 / p>

我的用于获取seatValue的模型

public function getSeats(){
      $query = $this->db->get('seat');
      if($query->num_rows() > 0){
      return $query->result();
      }  
 }

我用于显示seatNumber和seatLabel的视图

<tbody>
            <?php if(count ($seats)):?>

        <?php foreach ($seats as $seat):?>

        <tr>
            <td><input type="checkbox" name="seat_id[]" value=<?php echo $seat->seatNumber;?>></td>
            <td id="seatLabel" name="seat_label"><?php echo $seat->seatLabel;?></td>
        </tr>
        <?php endforeach;?>

        <?php else:?>
        <td>No Records Founds!</td>
        <?php endif;?>          
        </tbody>

我的控制器

public function message(){
    if ($this->input->post('submit') == 'Set Schedule') {
        $this->form_validation->set_rules('busNumber','Bus Number', 'required');
        $this->form_validation->set_rules('seat_id[]','Seats', 'required');
        $this->form_validation->set_rules('bookingDate','Date of Journey', 'required');
        $this->form_validation->set_rules('reportingTime','Reporting Time', 'required');
        $this->form_validation->set_rules('departureTime','Departure Time', 'required');

        if($this->form_validation->run()){
            $seat_ids = $this->input->post("seat_id[]");
            $seat_label = $this->input->post("seat_label");
            $busNumber = $this->input->post("busNumber");
            $bookingDate = $this->input->post("bookingDate");
            $reportingTime = $this->input->post("reportingTime");
            $departureTime = $this->input->post("departureTime");
            $this->load->model('Queries');
     $insert = $this->Queries->saveMessage($seat_ids, $seat_label, $busNumber, $bookingDate, $reportingTime, $departureTime);
            if($insert) {
                echo "Success";
            }
            else {
                echo "error";
            }
        } else { 
         echo validation_errors();
        }
    }

我将日期插入新数据库的模型

public function saveMessage($seat_ids, $seat_label, $busNumber, $bookingDate, $reportingTime, $departureTime){

    foreach($seat_ids as $seat_id)
    {
        $record = array(
        'seatNumber' => $seat_id, 
        'seatLabel'  => $seat_label
        'bookingDate' => $bookingDate,
        'reportingTime' => $reportingTime,
        'departureTime' => $departureTime, 
        'busNumber' => $busNumber,
        'seatUse' => 'Enabled',
        'seatStatus' => 'Available',);
        $this->db->insert('schedule', $record);
    }
return true;

}

数据库中出现问题，没有固定价值

错误

Answer 1

有这样的方法。如果您更改

SignInManager<User>
UserManager<User>

到

<td id="seatLabel" name="seat_label"><?php echo $seat->seatLabel;?></td>

但是，如果您不想显示文本框，则还要创建隐藏字段。

<td><input type="text" name="seat_label" value="<?php echo $seat->seatLabel;?>"></td>

如何从td标签获取价值并在codeigniter的foreach中使用它
