CodeIgniter Controller Bug修正

时间：2010-02-08 18:06:03 类别：技术访问：673

当 CodeIgniter 的 controller 名称和 model 或 library 的名称相同的时候，将产生错误。

以下修正了这个问题，从此可以为 controller, model, library 使用相同的 class name。

下载这个 MY_Router.php 并放到 application/libraries 文件夹即可

MY_Router.php

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

/*
* MY_Router
*
* Extended the core CI_Router class in order to force a different naming
* convention for controllers.
*
*/
class MY_Router extends CI_Router
{
   /*
   * Suffix in controller name
   *
   * @var String
   */
   private $_suffix = "Controller";

   /*
   * Call the parent constructor
   *
   * This is a requirement for extending base CI core class. Just abiding by
   * the rules.
   *
   * @access public
   * @return void
   */
   public function MY_Router()
   {
   parent::CI_Router();
   }

   /**
   * Validates the supplied segments. Attempts to determine the path to
   * the controller.
   *
   * @access private
   * @param array
   * @return array
   */
   function _validate_request($segments)
   {
   // Retain the original segments
   $orgSegments = array_slice($segments, 0);

   // Add suffix to the end
   $segments[0] = ucfirst($segments[0]) . $this->_suffix;

   // Does the requested controller exist in the root folder?
   if (file_exists(APPPATH.'controllers/'.$segments[0].EXT))
   {
   return $segments;
   }

   // OK, revert to the original segment
   $segments[0] = $orgSegments[0];

   // Is the controller in a sub-folder?
   if (is_dir(APPPATH.'controllers/'.$segments[0]))
   {
   // Set the directory and remove it from the segment array
   $this->set_directory($segments[0]);
   $segments = array_slice($segments, 1);

   if (count($segments) > 0)
   {
   // Add suffix to the end
   $segments[0] = ucfirst($segments[0]) . $this->_suffix;

   // Does the requested controller exist in the sub-folder?
   if ( ! file_exists(APPPATH.'controllers/'.$this->fetch_directory().$segments[0].EXT))
   {
   show_404($this->fetch_directory().$segments[0]);
   }
   }
   else
   {
   // Add suffix to the end
   $this->default_controller = ucfirst($this->default_controller) . $this->_suffix;

   $this->set_class($this->default_controller);
   $this->set_method('index');

   // Does the default controller exist in the sub-folder?
   if ( ! file_exists(APPPATH.'controllers/'.$this->fetch_directory().$this->default_controller.EXT))
   {
   $this->directory = '';
   return array();
   }

   }

   return $segments;
   }

   // Can't find the requested controller...
   show_404($segments[0]);
   }
}

使用方法：

<?php

class UsersController extends Controller
{
   public function __construct()
   {
   parent::__construct();
   }
}
