Question

在向数据库创建/插入数据时遇到问题。每当我提交表单时，它都会使用form_validation返回错误。它适用于我以前的数据库，但现在却没有。我怀疑这是关于数据类型的枚举。

控制器：

public function create_item() {
  $data = array(
   'checklist_id' => $this->input->post('checklist_id'),
   'title' => $this->input->post('title'),
   'description' => $this->input->post('description'),
   'type'  => $this->input->post('type'), //with enum type
   'section' => $this->input->post('section'),
   'order_no' => $this->input->post('order_no'),
   'status' => $this->input->post('status'), //with enum type
   'date_created' => $this->input->post('date_created')
   );

  $this->form_validation->set_rules('title','Item Title','trim|required|callback_alpha_dash_space');
  $this->form_validation->set_rules('order_no','Item Order','trim|required');

  $this->form_validation->set_message('alpha_dash_space', '%s appears to be invalid. Must contain only alphabets.');
  $this->form_validation->set_message('required', '%s field must not be empty. ');

  if ($this->form_validation->run() == FALSE) {
    $this->session->set_flashdata('error', ' Error adding an item!');
    redirect($this->agent->referrer());
  } else {
      $result = $this->checklist_item_model->put_item($data);
        if (!$result == TRUE) {
        $this->session->set_flashdata('success', 'Item added successfuly!');
        redirect('checklist_item', 'refresh');
      }
    }
 }

视图：

<select class="form-control" id="status" name="status">
  <option value="0">Incomplete</option>
  <option value="1">Complete</option>
</select>

在你的控制器中进行这样的验证

 $this->form_validation->set_rules('title','ItemTitle','trim|required|callback_alpha_dash_space');
 $this->form_validation->set_rules('order_no','Item Order','trim|required');

 $this->form_validation->set_message('alpha_dash_space', '%s appears to be invalid. Must contain only alphabets.');
$this->form_validation->set_message('required', '%s field must not be empty. ');
        if ($this->form_validation->run() == TRUE) {
           // do something here 
            $this->session->set_flashdata('success', 'Item added successfuly!');
    redirect('checklist_item', 'refresh');
        }

并在您的视图中轻松显示验证错误，您可以跟踪错误字段

<?php if(validation_errors()) { ?>
    <div class="alert alert-danger"><?php echo validation_errors(); ?></div>
    <p class="text-center mb30"></p>
    <?php } ?>

codeigniter使用枚举字段将数据插入数据库
