只有控制器的某些功能无法访问codeigniter中的会话数据

Question

i am new to codeigniter. i am setting the session in one controller. and i could access that session data from some functions of another controller. but only some functions cannot access the session data. please help me why this is happening.

i set the session by

$admin_details=array(
    'admin_id'=>$admin_id,
    'admin_name'=>$admin_name,
    'email'=>$email,
    'is_admin_logged_in'=>true,
    'user_type'=>'admin'
    );
$this->session->set_userdata($admin_details);

and i accessed it by

function manage_profile()
{

    if(!$this->session->userdata('is_admin_logged_in'))
    {
        $this->load->view('admin/test');
    }
}

but it is loading the view 'test'. i have loaded the session library and set the encryption key. it works in some other functions in the same controller.

It's because when you type $this->session->userdata('is_admin_logged_in') You're accessing the 'container' for the session.

$admin_details=array( 'admin_id'=>$admin_id, 'admin_name'=>$admin_name, 'email'=>$email, 'is_admin_logged_in'=>true, 'user_type'=>'admin' ); $this->session->set_userdata($admin_details);

You actually need to do this: $this->session->set_userdata('name_your_session_something',$admin_details);

Then to access it:

$session = $this->session->userdata('name_your_session_something'); $admin_logged = $session['is_admin_logged_in'];

if(!$admin_logged){ //if admin is not logged in do this }

It's a simple array situation.

So this should be the code:

Set Session:

$admin_details=array( 
        'admin_id'=>$admin_id, 
        'admin_name'=>$admin_name, 
        'email'=>$email, 
        'is_admin_logged_in'=>true, 
        'user_type'=>'admin' 
);
$this->session->set_userdata('name_your_session_something',$admin_details);

Get Session:

$session = $this->session->userdata('name_your_session_something'); 
$admin_logged = $session['is_admin_logged_in'];
