$user_is_student = $this->session->auth('user_student');
if (!$user_is_student)

show_error("No Access.");

What is 'auth'? The CI session library doesn't have an auth() method...

And please your [ code ] (remove the spaces) tags around your code, it's not very readable this way.

Thanks for your reply. auth function is inside MY_Session.php file.

function auth($access)
{
if ($this->CI->config->item('sess_encrypt_cookie') == TRUE AND $this->CI->config->item('sess_use_database') == TRUE AND $this->CI->config->item('sess_table_name') != '')
{
include(APPPATH.'config/auth'.EXT);
$authorized = $this->userdata($session_auth);

if ($authorized) {
if ($this->userdata($access) == TRUE) {

return TRUE;
}
else
{
return FALSE;
}
}
}
else
{
show_error('ENCRYPTION AND DATABASE MUST BE ENABLED - PLEASE READ /APPLICATION/CONFIG/AUTH.PHP');
return FALSE;
}
}
