ask:setcookie in codeigniter

[eluser]Unknown[/eluser]
hy all, I am still newbie in using codeigniter framework, I get a problem when I am using setcookie function in codeigniter

in this function I use setcookie but it does not work, I mean the cookie return "bool(false)" not return the value that put in the cookie

Code:

function login_verivication1(){
      
        
        //load form validation library
        $this->load->library('form_validation');
        
        //validation rule "field/input name", "Message that what fiel is wrong", "rule"
        $this->form_validation->set_rules('usrname', 'User Name', 'trim|required');
        $this->form_validation->set_rules('pass', 'Password ', 'trim|required');
        
        if ($this->form_validation->run()== FALSE){
             $data['error'] = '';
             $this->load->view('login_view',$data);// if validation false go back to login page and show error
        } else {
            $this->load->model('login_model');//load model that consist function for login
            $query = $this->login_model->login_verivication();//load verivication function from model will return true if username and password macth
                
                if ($query == true){
                    
                    
                    $database= $this->login_model->login_update('FREDY PRANAJAYA');// update LAST_LOGIN,SESSION,IP_LOGIN

                    // print_r($user);
                    $data = array (
                        'name'        => $database['name'],
                        'id'          => $database['id'],
                        'login_ok'    => true
                    );

                    $this->session->set_userdata($data);
                    //setcookie('loginok',$database['id']);
                    setcookie('login',6);
                    redirect('student','refresh');
                }else {
                    $data['error'] = "Your User Name or Password doesn't Macth. Try again";
                    $this->load->view('login_view', $data);
                }
            
        }
    }

but when I try like this, it work properly,

Code:

public function index()
        {
            
            setcookie('login',8);
            redirect('student');
        }

I don't know whats wrong with this, can anyone suggest solution for this? I appreciate every help and suggestion. thank you

Because it thinks your trying to pass an array to it when it is expecting a string value.

Code:

setcookie('loginok',$database['id']);

//change to
$id = $database['id'];
setcookie('loginok',$id);

You can pass arrays to setcookie but the have to serialized and then un-serialized so that it is a string.
