谁说controllers不能使用另一个controllers呢?
新建一个MY_Loader.php在\application\core\MY_Loader.php
用法:(引用controllers下的homepage/articles2)
PHP复制代码 $this->load->controller('homepage/articles2','homepage');
$this->homepage->index($lang,$mtypeid); 复制代码
MY_Loader.php源文件:
PHP复制代码 <?php if ( ! defined('BASEPATH')) exit('No direct script access allowed');
class MY_Loader extends CI_Loader
{
protected $_my_controller_paths = array();
protected $_my_controllers = array();
public function __construct ()
{
parent ::__construct ();
$this->_my_controller_paths = array(APPPATH );
}
public function controller ($controller, $name = '', $db_conn = FALSE)
{
if (is_array($controller))
{
foreach ($controller as $babe)
{
$this->controller($babe);
}
return;
}
if ($controller == '')
{
return;
}
$path = '';
// Is the controller in a sub-folder? If so, parse out the filename and path.
if (($last_slash = strrpos($controller, '/')) !== FALSE)
{
// The path is in front of the last slash
$path = substr($controller, 0, $last_slash + 1);
// And the controller name behind it
$controller = substr($controller, $last_slash + 1);
}
if ($name == '')
{
$name = $controller;
}
if (in_array($name, $this->_my_controllers , TRUE))
{
return;
}
$CI =& get_instance ();
if (isset($CI->$name))
{
show_error ('The controller name you are loading is the name of a resource that is already being used: '.$name);
}
$controller = strtolower($controller);
$controller=ucfirst($controller);//ci3之后强制要求首字母大写了
foreach ($this->_my_controller_paths as $mod_path)
{
if ( ! file_exists($mod_path.'controllers/'.$path.$controller.'.php'))
{
continue;
}
if ($db_conn !== FALSE AND ! class_exists('CI_DB'))
{
if ($db_conn === TRUE)
{
$db_conn = '';
}
$CI->load->database($db_conn, FALSE, TRUE);
}
if ( ! class_exists('CI_Controller'))
{
load_class ('Controller', 'core');
}
require_once($mod_path.'controllers/'.$path.$controller.'.php');
$controller = ucfirst($controller);
$CI->$name = new $controller();
$this->_my_controllers [] = $name;
return;
}
// couldn't find the controller
show_error ('Unable to locate the controller you have specified: '.$controller);
}
}
