Question

I am new in codeigniter. I have implemented a simple login system. I want to print out a username on my view page which is stored in sessions. here is my controller

<         


        

Answer 1

Just store the user name in the userdata (you've already done this!)

$this->session->set_userdata('username') = 'John Doe';

And retrieve it just like that

$username = $this->session->userdata('username');

Answer 2

controller file $data = array( 'username' => $result->name, );

view file

           <?php echo $this->session->userdata('username')?> 

Answer 3

$username = $this->session->userdata('username');

//Pass it in an array to your view like
$data['username']=$username;   
$this->load->view('test',$data);

//Then in you view you can display it as:
 echo $username;
