我正在创建一个应用程序并处理MY_Controller. 我正在使用消息库来显示常见消息。
这是 MY_Controller.php：
<?php

protected $partials = array(

'navigation' => 'partials/navigation',
'content' => 'partials/content',
'footer' => 'partials/footer'

如您所见，我正在使用 Phil Sturgeon 的模板库，并且正在使用 Jamierumbelow 的技术处理布局。当我设置有关表单插入失败的消息时，它很好。我可以像这样在_remap中显示它
echo $this->message->display();
在控制器中它工作正常但是当我在部分导航中调用它时它不显示消息。可能是什么问题。我已经尝试过 My_Controller 中的不同位置。它工作正常，但不是部分，甚至我已经以失败的形式尝试过，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>
正在使用会话的消息库可能是 flashdata，所以我认为它以某种方式丢失了会话数据。虽然我正在使用会话正确地自动加载它。
