CodeIgniter加载控制器在控制器HMVC内

本文介绍了CodeIgniter加载控制器在控制器HMVC内的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！ 问题描述

我使用 github/philsturgeon/codeigniter-template/为模板和我试图加载其他控制器视图作为部分实际视图。 我的主要问题是我不能从其他控制器添加元数据（javascripts，css）到主控制器。

application / core / MY_Loader .php

class MY_Loader extends CI_Loader { function __construct（） { parent :: __ construct（）; } 函数控制器（$ sController）{ global $ RTR; //解析sController字符串ex：demo / index $ aControllerData = explode（'/'，$ sController）; $ sMethod =！blank（$ aControllerData [1]）$ ​​b $ b？ $ 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（'无法找到指定的类：'。ucfirst（$ sController）。'。php'）; } $ this-> file（$ sPath。$ sController。'.php'）; $ sClass = new $ sClass; if（！method_exists（$ sClass，$ sMethod））{ set_status_header（503）; exit（'没有方法：'。$ sMethod。'in Class：'。ucfirst（$ sController）。'。php'）; } $ aArguments = func_get_args（）; return call_user_func_array（array（$ sClass，$ sMethod），array_slice（$ aArguments，1））; } } / *文件结束MY_Loader.php * / / *位置：./controllers/MY_Loader。 php * /

application / controllers / demo.php

<？php if（！define（'BASEPATH'））{ exit（'No direct script access' } 类Demo扩展CI_Controller { 函数索引（）{ $ this-> > controller（'welcome'）; $ this-> template-> set_partial（'footer'，'partials / footer'） - > build（'demo'）; } } / *文件结束welcome.php * / / *位置：./controllers/demo.php * /

application / controllers / welcome.php

<？php if（！defined（'BASEPATH'））exit（'不允许直接脚本访问）; 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'）; } }

进入url localhost /

我试图使用HMVC但结果相同。

解决方案

我在 github/EllisLab/CodeIgniter/pull/1818 有一个真正的HMVC，它的工作原理。我希望这将包括在即将发布的CodeIgniter版本。

我的测试结果显示在图像中。 controllers / demo.php

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

I'm using github/philsturgeon/codeigniter-template/ for the templates and I trying to load other controller view to actual view as a partial. My main problem is that I cant append meta data (javascripts, css) from other controller to the main controller.

application/core/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 */

application/controllers/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 */

application/controllers/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'); } }

After going to the url localhost/demo i got interface with partials and everything looks good, but I see that there are some libraries loaded too many times in my logs.

I was trying to use HMVC but there was the same result.

解决方案

I found a solution at github/EllisLab/CodeIgniter/pull/1818 There is a real HMVC and it works. I hope that this will be included in upcoming CodeIgniter release.

My test results are shown in the images. controllers/demo.php

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