Hey, i try to implementing cookies for login and save it to database. But i've a problem with this error.

A PHP Error was encountered

Severity: Notice

Message: Array to string conversion

Filename: core/Input.php

Line Number: 286

Success to login but if i disable the redirect, that error is showing and able to save into logindata

This my controller for login

PHP Code:

public function ceklogin()
    {
        $this->form_validation->set_rules('username', 'Username', 'required');
        $this->form_validation->set_rules('key', 'Password', 'required');
        $this->form_validation->set_error_delimiters('<div class="alert alert-danger">', '</div>');
        if ($this->form_validation->run() == FALSE)
        {
        $this->loginform();
        }
        else
        {
            $vUsername         = $this->input->post('username');
            $vPassword         = md5($this->input->post('key'));
            $tbl='user';
            $fieldpilih='*'; 
            $fieldkondisi=array('username'=>$vUsername,'password'=>$vPassword); 
            $hasil = $this->modeldonatur->pilihdata($tbl,$fieldkondisi,$fieldpilih);                
            if($hasil!=null)
            {                
                $tabel                    = 'logindata';
                $kondisi['username']     = $vUsername;
                $this->modeldonatur->hapusdata($tabel,$kondisi);
                $vToken                = $this->donaturlib->randstring();
                $tabel                 = 'logindata';
                $isi['username']    = $vUsername;
                $isi['sesi']        = $vToken;
                $isi['waktu']        = date("YmdHis");
                $this->modeldonatur->simpandata($tabel,$isi);
//Saving cookie                
                $vCookie1['sname']     = 'dnt_user_cookie';
                $vCookie1['value']     = $vUsername;
                $vCookie1['expire'] = '100';
                $this->input->set_cookie($vCookie1);
//saving token
                $vCookie2['name']    = 'dnt_sesi_cookie';
                $vCookie2['value']     = $vToken;
                $vCookie2['expire']     = '100';
                $this->input->set_cookie($vCookie2);
        //    redirect('login/nowwhere','refresh');        
            }
        else
            {
                $error = "Username atau Password Salah";
            //    $this->loginform($error);
            }

        }    
    } 


My model for the proses above

PHP Code:

function pilihdata($tbl,$fieldkondisi,$fieldpilih)
{       
           return $this->db->select($fieldpilih)
                ->from($tbl)
                ->where($fieldkondisi)
                ->get()
                ->result();                   
}
 function hapusdata($tabel,$kondisi)
        {
            $this->db->delete($tabel,$kondisi);
        }
 function simpandata($tabel,$isi)
        {
            $this->db->insert($tabel,$isi);
        } 


and the randstring in my lib

PHP Code:

function randstring()
  {
    $pass   = 60;
    $allchar  = "ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz1234567890";
    mt_srand  ((double) microtime()*1000000);
    $string   ='';
    for($i=0;$i<$pass;$i++)
    {
      $string .= $allchar{mt_rand(0,strlen($allchar) - 1)};
    }
    return $string;
  }

Can you show the Line Number: 286 and the base of the given array.
the error tells you that you use an array within a function who needs a string.

Thanks for trying help. My problem already solved.

There is a typo in saving cookies

PHP Code:

$vCookie1['sname']     = 'dnt_user_cookie'; 


It should be like this

PHP Code:

$vCookie1['name']     = 'dnt_user_cookie'; 


well, i'm a 'noob'

fine! ;o)

If only all bugs were that straightforward.
