将验证错误消息传递到Codeigniter中的smarty模板

Question

我需要帮助将验证错误传递到codeigniter（版本3.1.8）中的smarty（3.1.33）模板。

似乎在smarty模板中，您不能直接使用来自表单帮助程序的codeigniter函数，例如validation_errors()或form_error('fieldname').，至少在我看来，在smarty模板{validation_errors()}中类似这样不会产生任何结果。

因此，我尝试使用$this->form_validation->error_array()在控制器中获取错误消息，并将其分配给通过 $ this-> smartyci-> assign 分配给模板的变量。方法。尽管我提交了一个空白表格，但是模板中没有显示错误消息。

如果您有任何想法，请告诉我。

非常感谢，

下面是我的代码：

控制器（ Home.php ）：     

class Home extends CI_Controller
{
    public function __construct()
    {
        parent::__construct();

        $this->load->library( 'smartyci' );
        $this->load->library('form_validation');
        $this->load->helper('form');
    }

    public function index()
    {
        $title = "Court Monitor";
        $date = date("Y");
        //$this->smartyci->useCached('home.tpl' );
        $this->smartyci->assign('data', array(
            "logged_in" => false,
            "date" => $date,
            "title" => $title
        ));
        $this->smartyci->display('home.tpl');
        //print_r($result);
    }

    ............

    public function register_email ()
    {
        $title = "Registration";
        $date = date("Y");

        $this->form_validation->set_rules('nume', "Nume", "required");
        $this->form_validation->set_rules('prenume', "Prenume", "required");
        $this->form_validation->set_rules('email', "Email", "required|valid_email");

        $this->form_validation->set_message('required', 'This field is required');

        if ($this->form_validation->run() === false) {

            $this->smartyci->assign('data', array(
                "logged_in" => false,
                "date" => $date,
                "title" => $title,
                "errors" => $this->form_validation->error_array()
            ));
            $this->smartyci->display('register_email.tpl');
        } else {
            redirect('login');
        }

    }

模板（ register_email.tpl ）：

     {$data.title}
