消息库、My_Controller和__remap问题

Question

我正在创建一个应用程序，并用MY_Controller处理常见的事情。我正在使用消息库来显示常见消息。

下面是MY_Controller.php：

<?php
class MY_Controller extends CI_Controller {

    public $data            =   array();
    public $view            =   TRUE;
    public $theme           =   FALSE;
    public $layout          =   'default';    
    protected $redirect;    

    protected $models       =   array();
    protected $controller_model;
    protected $controller_class;
    protected $controller_library;  

    protected $controller_name;

    protected $partials     =   array(
                                    'meta'      =>  'partials/meta',
                                    'header'        =>  'partials/header',
                                    'navigation'    =>  'partials/navigation',
                                    'content'       =>  'partials/content',
                                    'footer'        =>  'partials/footer'
                                    );

    public function __construct()
    {
        parent::__construct();
        $this->output->enable_profiler(true);

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

        $this->controller_class =   $this->router->class;

        if(count($this->models)>0)

            }   
        }else{

            {
                $this->load->model($this->controller_model);

正如你所看到的，我正在使用Phil Sturgeon的模板库，并且我正在使用Jamierumbelow的技术来处理布局。当我在表单插入失败时设置了一条消息，它是正常的。我可以将它显示在_remap中，如下所示

echo $this->message->display();

在控制器中，它工作得很好，但当我在部分导航中调用它时，它不会显示消息。可能的问题是什么。我已经在My_Controller的不同地方试过了。它工作得很好，但不是在部分，甚至我已经尝试了失败的形式，我再次加载。这是我正在使用的消息库

这是我的导航部分。

<nav>
    <div id = "navigation">
        <ul id="menubar">
            <li>Home</li>
            <li>Downloads</li>
            <li>About Us</li>
        </ul>
    </div>
    <div id="breadcrumb">
        <div class="breadcrumbs">
            <!-- Here i will pull breadcrumbs dynamically-->
        </div>
        <!--<h3>Dashboard</h3>-->
    </div>
    <br  clear = "all"/>
    <div id="message">
    <?php 
    $data['message']    =   $message ;
    $this->load->view('messages/success',$data);?>
    </div>
</nav>

消息库使用的会话可能是flashdata，所以我认为它以某种方式丢失了会话数据。尽管我正确地使用了会话自动加载它。

我找到了问题所在。这很简单。我在配置文件中使用的基本url为空。

$config['base_url'] = '';

我必须像这样改变它

$config['base_url'] = 'http://localhost/myproject/';
