Php flashdata在codeigniter中完全不工作

嗨，伙计们，我试过很多东西，比如

$this->session->keep_flashdata();
$this->session->set_flashdata();

但是在重定向时启用加载消息，我将在下面发布我的代码，看看并帮助我解决这个问题

控制器：

        $params = array(
          'full_name' => $this->input->post('full_name'),
          'father_name' => $this->input->post('father_name'),
          'email' => $this->input->post('email'),
          'phone' => $this->input->post('phone'),
          'password' => $this->input->post('password'),
          'cnic_no' => $this->input->post('cnic_no'),
          'manager' => $this->input->post('manager'),
          'department_id' => $this->input->post('department_id'),
          'created_by' => $_SESSION['user_id'],
          'position' => $this->input->post('position'),
          'created_at' => $now,
          );
          $this->Maintainer_basic_model->insert($params);
          $this->session->set_flashdata('success', 'Maintainer added successfully');
          redirect('maintainer_basic/index');

<?php if($message = $this->session->flashdata('success')): ?>
  <div class="row">
    <div class="col-md-12 form-group">
        <div class="alert-success alert">
            <?php echo $message; ?>
        </div>
    </div>
  </div>
<?php endif ?>

查看：

        $params = array(
          'full_name' => $this->input->post('full_name'),
          'father_name' => $this->input->post('father_name'),
          'email' => $this->input->post('email'),
          'phone' => $this->input->post('phone'),
          'password' => $this->input->post('password'),
          'cnic_no' => $this->input->post('cnic_no'),
          'manager' => $this->input->post('manager'),
          'department_id' => $this->input->post('department_id'),
          'created_by' => $_SESSION['user_id'],
          'position' => $this->input->post('position'),
          'created_at' => $now,
          );
          $this->Maintainer_basic_model->insert($params);
          $this->session->set_flashdata('success', 'Maintainer added successfully');
          redirect('maintainer_basic/index');

<?php if($message = $this->session->flashdata('success')): ?>
  <div class="row">
    <div class="col-md-12 form-group">
        <div class="alert-success alert">
            <?php echo $message; ?>
        </div>
    </div>
  </div>
<?php endif ?>

根据您给定的代码，我认为您没有在config/autoload.php中加载会话库 检查下面的代码以了解情况

<?php
defined('BASEPATH') OR exit('No direct script access allowed');

$autoload['packages'] = array();

$autoload['libraries'] = array("session","form_validation","database");

$autoload['drivers'] = array();

$autoload['helper'] = array('url','path','form');

$autoload['config'] = array();

$autoload['language'] = array();

$autoload['model'] = array();

just do@devsiodera未工作

$message

不作为会话变量存在。只需回显

$this->session->flashdata（'success'）

。您正在设置一个键->值对，其中flashdata键为

success

，值为

Maintainer added successfulyy

@javierlaroulet我仅用$this->session->flashdata（'success'）进行了尝试但是仍然不工作您完全正确会话未包含在autoload.php中我已经包含了它，但再次尝试，但它仍然不工作实际上

此条件没有实现…是的，在编程过程中，您将始终尝试100%集中精力
