Codeigniter Rss,网站地图,路由配置_PHP教程

_ _,今天在成果不错,完成了网站的三个功能,RSS订阅,自动写网站地图,与路由的配置,好了,现在一 一记录下来.

一、路由配置

在未设定路由时,路径是这样的

[php]

http://www.xiuxiandou.com/content/it/13533/硅谷传奇投资人讲述初创企业家易犯的4大错误

content =>controller,it=>method,13533=>id,硅谷传奇投资人讲述初创企业家易犯的4大错误=>title

http://www.xiuxiandou.com/content/it/13533/硅谷传奇投资人讲述初创企业家易犯的4大错误

content =>controller,it=>method,13533=>id,硅谷传奇投资人讲述初创企业家易犯的4大错误=>title

设置路由后,访问路径为:

[php]

http://www.xiuxiandou.com/content-it-13533-硅谷传奇投资人讲述初创企业家易犯的4大错误

http://www.xiuxiandou.com/content-it-13533-硅谷传奇投资人讲述初创企业家易犯的4大错误

其它的类似,路径配置为

[php]

/*sitemap使用*/

$route['content-(:any)-(:num)'] = "content/$1/$2";

/*前台页面显示路由*/

$route['content-(:any)-(:num)-(:any)'] = "content/$1/$2/$3";

/*RSS订阅路由*/

$route['feed-rss-(:any)'] = "feed/rss/$1";

/*博客路由*/

$route['blog-(:num)-(:any)'] = "blog/blogview/$1/$2";

$route['blog-blogtypes-(:any)']="blog/blogtypes/$1";

/**留言**/

$route['me'] = "indexs/me";

/**模板**/

$route["template"]="indexs/template";

/**今日更新**/

$route["indexs-(:any)"]="indexs/$1";

/*sitemap使用*/

$route['content-(:any)-(:num)'] = "content/$1/$2";

/*前台页面显示路由*/

$route['content-(:any)-(:num)-(:any)'] = "content/$1/$2/$3";

/*RSS订阅路由*/

$route['feed-rss-(:any)'] = "feed/rss/$1";

/*博客路由*/

$route['blog-(:num)-(:any)'] = "blog/blogview/$1/$2";

$route['blog-blogtypes-(:any)']="blog/blogtypes/$1";

/**留言**/

$route['me'] = "indexs/me";

/**模板**/

$route["template"]="indexs/template";

/**今日更新**/

$route["indexs-(:any)"]="indexs/$1";

二、RSS

在libraries目录下创建Rss.php文件,主要负责生成RSS格式的数据内容

[php]

/**

* Rss

*/

class Rss{

public function write_rss($in_datas){

$CI=& get_instance();

$CI->load->helper('xml');

$CI->load->helper('text');

$xml_str=""

."";

if(!emptyempty($in_datas)){

$xml_str.=""

.""

.""

."".$in_datas["feed_url"].""

."".$in_datas["page_description"].""

."zh-cn "

."1"

."hourly "

."Copyright (C) Xiuxiandou.com. All rights reserved."

."http://www.xiuxiandou.com";

if(!emptyempty($in_datas["xml_datas"])){

foreach($in_datas["xml_datas"] as $k => $v){

foreach($v as $xml){

$xml_str.=" "

.""

."".site_url("content-$k-$xml->id-".xml_convert($CI->mytool->get_title($xml->subject))).""

."".site_url("content-$k-$xml->id-".xml_convert($CI->mytool->get_title($xml->subject))).""

."message, 600))."]]>"

."".date('Y-m-d h:i:s',$xml->dateline)." "

."$xml->url"

."";

}

}

}

$xml_str.="";

}

$xml_str.="";

return $xml_str;

}

}

/**

* Rss

*/

class Rss{

public function write_rss($in_datas){

$CI=& get_instance();

$CI->load->helper('xml');

$CI->load->helper('text');

$xml_str=""

."";

if(!empty($in_datas)){

$xml_str.=""

.""

.""

."".$in_datas["feed_url"].""

."".$in_datas["page_description"].""

."zh-cn "

."1"

."hourly "

."Copyright (C) Xiuxiandou.com. All rights reserved."

."http://www.xiuxiandou.com";

if(!empty($in_datas["xml_datas"])){

foreach($in_datas["xml_datas"] as $k => $v){

foreach($v as $xml){

$xml_str.=" "

.""

."".site_url("content-$k-$xml->id-".xml_convert($CI->mytool->get_title($xml->subject))).""

."".site_url("content-$k-$xml->id-".xml_convert($CI->mytool->get_title($xml->subject))).""

."message, 600))."]]>"

."".date('Y-m-d h:i:s',$xml->dateline)." "

."$xml->url"

."";

}

}

}

$xml_str.="";

}

$xml_str.="";

return $xml_str;

}

}

2、RSS控制类

[php]

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

/**

* 2013-2-25:RSS订阅

*/

class Feed extends CI_Controller{

public function index(){

$it=$this->mcom_model->query_Bywhere(mymsg::BT_ITINFO,array("riqi"=>$this->mytool->get_ymd()));

$game=$this->mcom_model->query_Bywhere(mymsg::BT_GAME,array("riqi"=>$this->mytool->get_ymd()));

$blog=$this->mcom_model->query_Bywhere(mymsg::BT_BLOG,array("riqi"=>$this->mytool->get_ymd()));

$movie=$this->mcom_model->query_Bywhere(mymsg::BT_MOVIE,array("riqi"=>$this->mytool->get_ymd()));

$book=$this->mcom_model->query_Bywhere(mymsg::BT_BOOK,array("riqi"=>$this->mytool->get_ymd()));

$in_datas["xml_datas"]=array("it"=>$it,"game"=>$game,"blog"=>$blog,"movie"=>$movie,"book"=>$book);

$this->_comm($in_datas);

}

public function rss(){

$this->load->helper('xml');

$this->load->helper('text');

$key= $this->uri->segment(3);

$db_table= $key=="it"?"bt_itinfo":"bt_$key";

$table_exist=$this->mcom_model->table_exists($db_table);

if($table_exist){

$in_datas["xml_datas"]=array($key=>$this->mcom_model->query_Bywhere($db_table,array("riqi"=>$this->mytool->get_ymd())));

$this->_comm($in_datas);

}else{

show_404();

}

}

private function _comm($in_datas){

$in_datas['feed_name'] = "休闲豆 RSS";

$in_datas['feed_url'] = base_url()."free";

$in_datas['page_description'] = '休闲豆,IT资讯,IT电子书,游戏种子,电影BT RSS';

$in_datas['creator_email'] = '[e-mail]';

$in_datas['page_language']="zh-zn";

$out_datas["xml"]=$this->rss->write_rss($in_datas);

header("Content-Type: text/xml");

$this->load->view("rss",$out_datas);

}

}

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

/**

* 2013-2-25:RSS订阅

*/

class Feed extends CI_Controller{

public function index(){

$it=$this->mcom_model->query_Bywhere(mymsg::BT_ITINFO,array("riqi"=>$this->mytool->get_ymd()));

$game=$this->mcom_model->query_Bywhere(mymsg::BT_GAME,array("riqi"=>$this->mytool->get_ymd()));

$blog=$this->mcom_model->query_Bywhere(mymsg::BT_BLOG,array("riqi"=>$this->mytool->get_ymd()));

$movie=$this->mcom_model->query_Bywhere(mymsg::BT_MOVIE,array("riqi"=>$this->mytool->get_ymd()));

$book=$this->mcom_model->query_Bywhere(mymsg::BT_BOOK,array("riqi"=>$this->mytool->get_ymd()));

$in_datas["xml_datas"]=array("it"=>$it,"game"=>$game,"blog"=>$blog,"movie"=>$movie,"book"=>$book);

$this->_comm($in_datas);

}

public function rss(){

$this->load->helper('xml');

$this->load->helper('text');

$key= $this->uri->segment(3);

$db_table= $key=="it"?"bt_itinfo":"bt_$key";

$table_exist=$this->mcom_model->table_exists($db_table);

if($table_exist){

$in_datas["xml_datas"]=array($key=>$this->mcom_model->query_Bywhere($db_table,array("riqi"=>$this->mytool->get_ymd())));

$this->_comm($in_datas);

}else{

show_404();

}

}

private function _comm($in_datas){

$in_datas['feed_name'] = "休闲豆 RSS";

$in_datas['feed_url'] = base_url()."free";

$in_datas['page_description'] = '休闲豆,IT资讯,IT电子书,游戏种子,电影BT RSS';

$in_datas['creator_email'] = '[e-mail]';

$in_datas['page_language']="zh-zn";

$out_datas["xml"]=$this->rss->write_rss($in_datas);

header("Content-Type: text/xml");

$this->load->view("rss",$out_datas);

}

}

运行

[html]

生成结果如下

3、网站地图

网站地图主要根据sitemaps.xml协议拼写的XML,协议地址:http://www.sitemaps.org/protocol.html

1、加载libraries目录下的sitemaps.php类,内容如下

[php]
