                        'username' => $username

                }else{

                    redirect(site_url("Users/login"));
                }


            }else{

            }

        }


        $data['pagetitle']="Log in";
        $this->load->view("users/login",$data);
    }
    public function dashboard()

                    echo"welcom";

                }

Answer 1

在控制器或自动加载文件中加载会话库：
$this->load->library('session');

Answer 2

在您的模型中替换此功能：

     function mainlogin($username,$password) {
            $this->db->select('*');
                $this->db->from("users");
                $this->db->where('username',$username);
                $this->db->where('password',$password);
                $sql=$this->db->get();

            if($sql->num_rows() == 1)
            {
                return $sql->result();
            }else{
                return false;
            }

        }

无法使用PHP和Codegniter启动会话
