加载

$this->load->helper('url');

将redirect('HomeController/index');更改为redirect(base_url() . 'HomeController');

注意：如果您重定向到控制器index()，默认情况下会调用该函数

编辑01

public function checkLogin()
{
    $this->form_validation->set_rules('username','Username','required|valid_email');
    $this->form_validation->set_rules('password','Password','required|callback_verifyUser');

    if($this->form_validation->run()== false)
    {
        $this->load->view('login');
    }
    else
    {
        $user= $_POST['username'];
        $pass= $_POST['password'];

        $this->load->model('LoginModel');
        $result = $this->LoginModel->login($user, $pass);
        if($result==1)
        {
            //call your page
            //redirect(base_url() . 'HomeController');
        }
        else
        {
            //$this->form_validation->set_message('verifyUser','Incorrect user........');
            $this->load->view('login');//form view
        }

    }

}

在模型中

public function login($user, $pass)
{
    $query = $this->db->query("SELECT *FROM members WHERE user='$user' AND pass='$pass'");
    $result = $query->result_array();

    $count = count($result);
    if($count==1)
    {
        $log = 1;
        return $log;
    }
    else
    {
        $log = 0;
        return $log;
    }
}

正确的用户名和密码后，页面不会重定向
