Cookie help

This makes no sense....ok first I validate the user login
-Then I check to see if they checked Remember Me..if they did this is the code that runs (it works, because cookies are being added to my browser)

Code:

if($this->input->post('rememberMe') && $this->input->post('rememberMe') == '1')
    {
     setcookie('username',$username,time()+80);
     setcookie('password',md5($password),time()+80);
     setcookie('is_logged_in','true',time()+80);
    }

-Then as users move from page to page it asks if they are logged in. Here's my function for that:

Code:

// Login check function
public function loggedin()
{
  if($this->session->userdata('username'))
  {
   return true;
  }
  
  // Login with cookie
  elseif ($this->input->cookie('username', TRUE) && $this->input->cookie('password', TRUE))
  {
    $username = $this->input->cookie('username', TRUE);
    $password = $this->input->cookie('password', TRUE);
    
    $this->load->model('membership_model');
    $q = $this->membership_model->validate();
    
    if($q)
    {
     setcookie('username',$username,time()+80);
     setcookie('password',md5($password),time()+80);
     setcookie('is_logged_in','true',time()+80);
    }
    
    return true;    
  }else{
   return false;
  }
}

Why is the elseif in my loggedin() function not working? I know that the cookies are being made by my first code snippet, because I can see them in my browser. However, the loggedin function is not going through, thus leaving a false validation.

I don't think that the CI way of doing cookies

Code:

$this->input->cookie('username', TRUE)

is actually working.
