CodeIgniter：显示动态标题问题

Question

Can someone help me out with this piece of code.

I have a template set up like this:

system/core/Loader.php :

public function template($view, $vars = array(), $return = FALSE)
    {
        $template  = $this->view('includes/header', array(), $return);
        $template  = $this->view('includes/navigation', array(), $return);
        $template .= $this->view($view, $vars, $return);
        $template .= $this->view('includes/footer', array(), $return);

        if ($return)
        {
            return $template;
        }
    }

It works perfect but when I try this to display a dynamic title, it doesn't want to display the title. I guess because the data is passed to content_home rather then to includes/header:

my controller:

public function home() {
        $this->load->model("model_get");
        $data["page_title"] = "Home Page";
        $data["results"] = ($this->model_get->getData("home"));
        $this->load->template("content_home",$data);
    }

includes/header.php

<title><?php echo (isset($page_title)) ? $page_title : 'Default title text'; ?> </title>

Any ideas how to work it out ??

Thanks : )

In your views folder make a template file like this,
we'll call it template_web.php

<?php 

// the preset view files for your template
$this->load->view('includes/header');     
$this->load->view('includes/navigation'); 

// in this example we will have our content view files in a folder called 'web' 
$templatefolder = 'web/';

// this is where you can pass in 'content' view files that are unique for the page 
// this example has 3 placeholders you can put as many as you need 

if(isset($content01))
$this->load->view($templatefolder.$content01);

if(isset($content02))
$this->load->view($templatefolder.$content02);

if(isset($content03))
$this->load->view($templatefolder.$content03);

 // preset template footer file 
 $this->load->view('includes/footer'); 

ok now in your controller methods

// data you want to pass to your header  
$data['page_title'] = 'Awesome Home Page';

// other data
$data['bigbagofdata'] = $this->bigBagOf->awesomeData ; 

// the name of the view files 
$data['content01'] = 'homepage';
$data['content02'] = 'homepage_banner'; 

// your template 
$this->load->view( 'template_web', $data );

data can be passed to any of the view files. and its very easy to set up different templates this way.
