Online-Benutzerstatus auf Codeigniter

Question

Ich möchte wissen, wie Online-Benutzerstatus zu ändern, wenn der Benutzer sich anmeldet. Ich habe danach gesucht, aber es gibt keine Antwort auf meine Frage. Ich bin neu beim Lernen dieses Codeigniters. Ich wünschte, ihr könnt mir bitte für mein Problem helfen.

Controller:

public function signdevice() { 
    $device = $this->input->post('device'); 
    $pass = $this->input->post('password'); 
    $data = array(
     'device' => $device, 
     'password' => $pass, 
     'status' => $status 
    ); 
    $status = 1; 
    $res = $this->db->get_where('devices', $data); 
    if ($res->num_rows() > 0) { 
     $this->session->set_userdata(
      array(
       'signin' => TRUE, 
       'device' => $device, 
       'status' => $status 
      ) 
     ); 
     $data = array('device' => $device, 'password' => $pass, 'status' => 1); 
     $this->db->where('device', '$device'); 
     $this->db->update('devices', $data); 
     redirect(base_url('pelanggan')); 
    } else { 
     $this->session->set_flashdata('result_login', 'Wrong Username or Password.'); 
     redirect(base_url()); 
    } 
} 

Modelle:

function login($user,$pass) 
{ 
    $this->db->where('device', $user); 
    $this->db->where('password', $pass); 
    $query = $this->db->get('devices'); 
    if($query->num_rows()==1) { 
     return $query->row_array(); 
    } else { 
     $this->session->set_flashdata('error', 'Username atau password salah!'); 
     redirect('login'); 
    } 
} 

function update($id,$stat) 
{ 
    $data['status'] = $stat; 
    $stat = 1; 
    $this->db->where('kd_device', $id); 
    $this->db->update('devices', $stat); 
    return TRUE; 
}

Sie haben mehrere Linie & fehl am Platze Code fehlt.

Controller:

public function signdevice() { 
    $device = $this->input->post('device'); 
    $pass = $this->input->post('password'); 
    $data = array(
     'device' => $device, 
     'password' => $pass, 
     'status' => 0 // changed value to 0 
    ); 
    $status = 1; 
    $res = $this->db->get_where('devices', $data); 
    if ($res->num_rows() > 0) { 
     $this->session->set_userdata(
      array(
       'signin' => TRUE, 
       'device' => $device, 
       'status' => $status 
      ) 
     ); 
     $data = array('device' => $device, 'password' => $pass, 'status' => 1); 
     $this->db->where('device', $device); // removed quotes 
     $this->db->update('devices', $data); 
     redirect(base_url('pelanggan')); 
    } else { 
     $this->session->set_flashdata('result_login', 'Wrong Username or Password.'); 
     redirect(base_url()); 
    } 
} 

Modell:

... 
function update($id,$stat) 
{ 
    $stat = 1; // swapped this line with below 
    $data['status'] = $stat; // swapped this line with above 
    $this->db->where('kd_device', $id); 
    $this->db->update('devices', $data); // maybe what you want to save is $data? 
    return TRUE; 
}
