我正在使用http://github.com/philsturgeon/codeigniter-template/作为模板，并尝试将其他控制器视图作为部分加载到实际视图中。我的主要问题是我无法将元数据（javascripts、css）从其他控制器附加到主控制器。

应用程序/核心/MY_Loader.php 

class MY_Loader extends CI_Loader
{
    function __construct()
    {
        parent::__construct();
    }

    function controller( $sController ) {
        global $RTR;

        // Parse the sController string ex: demo/index
        $aControllerData = explode( '/', $sController );

        $sMethod = !empty( $aControllerData[1] )
            ? $aControllerData[1]
            : 'index'
        ;
        $sController = !empty( $aControllerData[0] )
            ? $aControllerData[0]
            : $RTR->default_controller
        ;

        $sClass = ucfirst( $sController );

        $sPath = APPPATH . 'controllers/';

        if ( !file_exists( $sPath . $sController . '.php' ) || class_exists( $sClass, FALSE ) ) {

            set_status_header( 503 );
            exit( 'Unable to locate the specified class: '. ucfirst( $sController ).'.php' );
        }
        $this->file( $sPath . $sController . '.php' );
        $sClass = new $sClass;

        if ( !method_exists( $sClass, $sMethod ) ) {
            set_status_header( 503 );
            exit( 'There is no Method: ' . $sMethod . ' in Class: '. ucfirst( $sController ).'.php' );
        }
        $aArguments = func_get_args();
        return call_user_func_array( array( $sClass, $sMethod ), array_slice( $aArguments, 1));
    }

}


/* End of file MY_Loader.php */
/* Location: ./controllers/MY_Loader.php */

应用程序/控制器/demo.php

<?php if ( !defined( 'BASEPATH' ) ) {
    exit( 'No direct script access allowed' );
}

class Demo extends CI_Controller
{

    function index() {

        $this->load->controller('welcome');
        $this->template->set_partial('footer', 'partials/footer')->build('demo');
    }
}

/* End of file welcome.php */
/* Location: ./controllers/demo.php */

应用程序/控制器/welcome.php

<?php if ( ! defined('BASEPATH')) exit('No direct script access allowed');
class Welcome extends CI_Controller {

    public function index()
    {
        echo 'Loaded welcome controller';
        $this->template->title('Welcome');
        $this->template->append_metadata('<script src="/js/jquery.js"></script>');
        $this->template->set_partial('footer', 'partials/footer')->build('welcome_message');
    }
}

转到 url localhost/demo 后，我得到了部分接口，一切看起来都很好，但我看到在我的日志中加载了一些库太多次。

我试图使用 HMVC，但结果相同。

我在https://github.com/EllisLab/CodeIgniter/pull/1818找到了一个解决方案。 有一个真正的 HMVC，它可以工作。我希望这将包含在即将发布的 CodeIgniter 版本中。

我的测试结果显示在图像中。控制器/demo.php

class Demo extends CI_Controller {

    public function index()
    {
        $this->load->controller('welcome');
        $this->load->view('demo');
    }
}

结果
