Login Controller- MVC PHP

Currently, i'm working with MVC pattern applied in PHP language. Please anyone help to define logic for login controller. Here is the code that i have done.

public function login($name = '') {
    //do logic check and change template of model
    // or redirect to dashboard
    if(isset($_GET['uname'])) {
        if(empty($_GET['uname']) || empty($_GET['pwd'])) {
            $this->model->template = 'user/login.php';
                $this->model->data = array('content' => 'You login information is not complete ', 'link' => 'home');
                $this->view->render();
        } else {
            $data = array('uname' => $_GET['uname'], 'pwd' => $_GET['pwd'] );
            if($this->model->login($data) != 0) {
                Session::setSession('uname',$_GET['uname']);
                Session::setSession('loggedIn', true);

                header("Location: /eversoft/public/home");
            } else {
                $this->model->template = 'user/login.php';
                $this->model->data = array('content' => 'You login information is not correct ', 'link' => 'home');
                $this->view->render();
            }
        }
    } else {
        $this->model->template = 'user/login.php';
        $this->model->data = array('content' => 'Hello from login', 'link' => 'home');
        $this->view->render();
    }
    $this->model->template = 'user/login.php';
    $this->model->data = array('content' => 'Hello from login', 'link' => 'home');
    $this->view->render();
}
