At the moment I think about login script. Idea – when you submit login and password, they checks into model and if login and password is correct, script shows a message about completed login process. But if I put in view echo $message;<\/code> and I am at login page, kohana shows error – Undefined variable $message. But when I am at page, where the variable defined, all working. How to realize this idea.<\/p>\n

EDIT!<\/p>\n

class Controller_About extends Controller_Template {\n\npublic function action_index() {\n    session_start();\n    if (isset($_SESSION['lietotajvards'])) {\n\n        if (!empty($_POST['virsraksts']) and !empty($_POST['saturs'])) {\n\n            $name = Model::factory('index')->insert_names($_POST['virsraksts'], $_POST['saturs']);\n            $result = $name;\n            $this->template->site_name = Kohana::$config->load('common')->get('site_name');\n            $this->template->site_description = Kohana::$config->load('common')->get('site_description');\n            $this->template->page_title = 'About';\n            $this->template->content = View::factory('about\/about')->set('result', $result);\n            $this->template->styles[] = 'index\/index';\n        } else {\n            $this->template->site_name = Kohana::$config->load('common')->get('site_name');\n            $this->template->site_description = Kohana::$config->load('common')->get('site_description');\n            $this->template->page_title = 'About';\n            $this->template->content = View::factory('about\/about');\n            $this->template->styles[] = 'index\/index';\n        }\n    } else {\n        if (!empty($_POST['lietotajvards']) and !empty($_POST['parole'])) {\n            $user_model = Model::factory('index')->valide($_POST['lietotajvards'], md5($_POST['parole']));\n            foreach ($user_model as $d) {\n                if ($_POST['lietotajvards'] == $d['lietotajvards'] and md5($_POST['parole']) == $d['parole']) {\n                    $_SESSION['lietotajvards'] = $_POST['lietotajvards'];\n                    $this->template->content = View::factory('login\/index')->set('message', 'Ielogosanas veiksmiga!');\n                    echo '';\n                }\n            }\n        }\n        $this->template->site_name = Kohana::$config->load('common')->get('site_name');\n        $this->template->site_description = Kohana::$config->load('common')->get('site_description');\n        $this->template->page_title = 'About';\n        $this->template->content = View::factory('login\/index');\n        $this->template->styles[] = 'index\/index';\n    }\n}}\n<\/code><\/pre>\n
I have problem only with variable $message.<\/p>\n
\n\n    \n    \n    \n\n<\/code><\/pre>\n
    \n
  1. \n
    The problem is you’re setting the template content at the very end, which is overriding what you’ve previously set it to. Try changing<\/p>\n
    $this->template->content = View::factory('login\/index')->set('message', 'Ielogosanas veiksmiga!');\n<\/code><\/pre>\n
    to<\/p>\n
    $message = 'Ielogosanas veiksmiga!';\n<\/code><\/pre>\n
    and then at the end change the view loading to<\/p>\n
    $this->template->content = View::factory('login\/index')->bind('message',$message);\n<\/code><\/pre>\n
    Using the bind method on the view will pass a null value to the view if the variable has not been set inside your controller.<\/p>\n<\/li>\n<\/ol>\n
