在会话中保存下拉列表中的数据并在另一个页面中显示 Codeigniter

Question

您好，我在使用 codeigniter 时遇到问题。这里我想把通过下拉选中的数据保存到session中，然后把选中的数据展示到一个叫step4的页面。我已经试过了，但是当我显示数据时，它没有出现。

这是脚本：

控制器Step1.php

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

class Step1 extends CI_Controller {

  function __construct() {
    parent::__construct();
    $this->load->helper('url');
    $this->load->library('session');
    $this->load->model('M_datasiswa');
  }

    public function step1()
    {
    $data['departemen'] = $this->M_datasiswa->get_departemen();
    $data['tahunajaran'] = $this->M_datasiswa->get_tahunajaran();
        $this->load->view('v_step1',$data);
  }

  function save_data(){
    $depart = $this->input->post('kode_departemen');
    $tahun = $this->input->post('kode_tahun');
    $asal = $this->input->post('kode_asal');

    $data = array(
      'departemen' => $depart,
      'proses' => $tahun,
      'asal' => $asal
    );
    $this->session->set_userdata($data);
    redirect('step4');

    }



}

v_step1.php

<form action="<?php echo base_url('Step1/save_data'); ?>" method="post">
      <table border="0" style="text-align:left; margin-left: auto; margin-right: auto; width:97%; margin-top:50px;">

          <td> <input type="text" placeholder="Nama Lengkap" class="tulisanDalamTabel" style="width:98%; margin-left: 7px; height:40px;"/> </td>
          <td> <?php $this->session->userdata('departemen') ?></td>
          <td class="tulisanDalamTabel"> &nbsp; Nama Panggilan </td>
          <td> <input type="text" placeholder="Nama Panggilan" class="tulisanDalamTabel" style="width:97%; margin-left: 1px; height:40px;"/> </td>
        </tr>

谢谢，希望有人能帮助我。

您忘记使用 echo 进行打印

<td> <?php $this->session->userdata('departemen') ?></td>

改为这样做

<td> <?php echo $this->session->userdata('departemen') ?></td>
