CI 基础

Welcome 控制器

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

class Welcome extends CI_Controller {
　　public function index(){
　　　　$this->load->view('index_index');
　　}
　　public function haha(){
　　　　$this->load->view('index_haha');
　　}
}

http://moumou.com/index.php/welcome/haha/

============================================================

.htaccess

RewriteEngine on
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^(.*)$ index.php/$1 [L]

http://moumou.com/

http://moumou.com/welcome/haha/

=============================================================
修改/application/config/routes.php

//$route['default_controller'] = "welcome";
$route['default_controller'] = "game";

http://moumou.com/

http://moumou.com/game/haha

game 控制器

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

class game extends CI_Controller {
　　public function index(){
　　　　$this->load->view('game_index');
　　}
　　public function haha(){
　　　　$this->load->helper('url');
　　　　$haha['data'] = $this->uri->segment(3);
　　　　$this->load->view('game_haha',$haha);
　　}
}

http://moumou.com/game/haha/2

$this->uri->segment(3) 为2

-----------------------------
修改/application/config/routes.php
添加

$route['url/(:num)'] = "game/haha";

http://moumou.com/url/2

$this->uri->segment(3) 为空
$this->uri->segment(2) 为2

--------------------------------------------------

修改

$route['url/(:any)'] = "game/haha";

http://moumou.com/url/cv2.html

-------------------------------------------------

两个控制器的

$route['g/(:any)'] = "game/haha";
$route['f/d/(:any)'] = "fuck/kao";

-------------------------------------------------

同一个控制器的两个方法

$route['gi/(:any)'] = "game/index";
$route['gh/(:any)'] = "game/haha";

【以上都要注意 $this->uri->segment(n)】

===============================================================
修改/application/config/routes.php

//$config['url_suffix'] = '';
$config['url_suffix'] = '.html';

game 控制器

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

class game extends CI_Controller {
　　public function index(){
　　　　$this->load->helper('url');
　　　　$index['data'] = "数据";
　　　　$index['title'] = "这是标题";
　　　　$this->load->view('game_index_head',$index);
　　　　$this->load->view('game_index_body');
　　　　$this->load->view('game_index_foot');
　　}
}

在第一个里面传递$index就行，即使head，body里面都调用index里面的数据
