Hello I have a problem using codeigniter. Here I want to save the data selected through the dropdown into a session, then display the selected data to a page called step4. I have tried but when I display the data, it does not appear.

Here is the script:

Controller 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">

        </tr>

Thanks, hope someone can help me.

CodePudding user response：

You forgot to print using echo

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

Do this instead

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