Question

I’m returing session data from my database, but I’m unable to display the LastName attribute of my table, and I don’t know why because the FirstName returns sucessfully. I do have the LastName attribute in my database. my view is giving me the error:Message: Undefined index: Lastname // Filename: controllers/home.php

here is my model

Class Membership_model extends CI_Model 
{

function __construct()
{
parent::__construct();
}



function validate_student($username,$password){
   $this -> db -> select('Student_ID, Firstname,Lastname, password');

   $this -> db -> from('Student');

   $this -> db -> where('Student_ID = ' . "'" . $username . "'");
   $this -> db -> where('password = ' . "'" . MD5($password) . "'");
   $this -> db -> limit(1);

    //If it is all correct

    $query = $this -> db -> get();

    if($query->num_rows() == 1){

         return $query->result();


    }else{
        return false;
    }
}

controller: home

   class Home extends CI_Controller {

     function __construct()
     {
       parent::__construct();
     }

     function index()
     {
       if($this->session->userdata('logged_in'))
       {
         $session_data = $this->session->userdata('logged_in');
         $data['Firstname'] = $session_data['Firstname'];
         $data['Lastname'] = $session_data['Lastname'];
         $this->load->view('home_view', $data);
       }

home view:

<h2>Welcome <?php echo $Lastname; ?>

Answer 1

print the session data $session_data , update your question with that , the error is you have no index Lastname in $session_data['Lastname'];,

form where you set the session data logged_in , please update your question with that also
