CodeIgniter: how to generate sitemap for a website _ PHP Tutorial

CodeIgniter is used to generate a site map. 1. create a controller named sitemap and copy the code as follows :? Phpif (! Defined (BASEPATH) exit (Nodirectscriptaccessallowed); classSitemapextendsCI_Controller { 1. a controller named sitemap is created.

The code is as follows:

If (! Defined ('basepath '))
Exit ('no direct script access allowed ');

Class Sitemap extends CI_Controller {
Public function _ construct (){
Parent: :__ construct ();
$ This-> load-> model ('sitemapxml ');
}

Function index (){
$ Data ['posts'] = $ this-> sitemapxml-> getArticle ();
$ Data ['category'] = $ this-> sitemapxml-> getCategory ();
$ This-> load-> view ('sitemap. php', $ data );
}
}

First, load the sitemapxml model class. The index method calls two methods to obtain the article list and category list respectively, and output them in the template.

2. create a model named sitemapxml

The code is as follows:

Class Sitemapxml extends CI_Model {
Public function _ construct (){
Parent: _ construct ();
$ This-> load-> database ();
}

Public function getArticle (){
$ This-> db-> select ('Id, post_date, post_name ');
$ This-> db-> order_by ('post _ date', 'desc ');
$ Result = $ this-> db-> get ('posts ');
Return $ result-> result_array ();
}

Public function getCategory (){
$ This-> db-> select ('c _ sname ');
$ Result = $ this-> db-> get ('Category ');
Return $ result-> result_array ();
}
}

The model defines two methods to obtain the document list and category list.
