我阅读了很多论坛主题,但我没有找到满足我需求的答案。
我正在运行博客系统,每篇文章的当前网址如下:www.example.com/controller/method/id
。但是,对于每篇文章,我都有一个存储在数据库中的标题,并希望在网址中使用该标题,所以它看起来像这样:www.example.com/title
答案 0 :(得分:0)
你好,你要求提供大量代码而你自己没有做任何研究。
最好的方法是在您的标题中使用ID:http://www.example.com/id/long-title
它比仅使用标题要好得多,因为:
为了使我的提案有效,您需要:
设置路由(application / config / routes.php)
//leave two CodeIgniter's routes on top
$route['default_controller'] = "welcome";
$route['404_override'] = '';
//leave this two routes in this order + make them LAST routes
$route['(:num)'] = 'blog/post/$1'; //if only id is in url
$route['(:num)/(:any)'] = 'blog/post/$1/$2'; //if id and title is in url
设置控制器(application / controllers / blog.php)
<?php if ( ! defined('BASEPATH')) exit('No direct script access allowed');
class Blog extends CI_Controller {
public function __construct()
{
parent::__construct();
//load models helpers etc if not autoloaded
$this->load->helper('url');
}
public function index()
{
echo 'should throw 404 or redirect home because id was not provided';
}
public function post($id = null, $title = '')
{
if (!$this->validId( $id )) redirect(); //redirect somewhere because id of post is invalid search/404/home...
if (empty(trim($title))) {
redirect(base_url().$id.'/'.$this->getTitle($id), 'location', 301); //redirect to same page search engines friendly (301 header)
}
//display what you need
echo 'params; id: ' . $id . ' title: ' . $title;
}
private function validId($id)
{
if (is_numeric($id))
return true; //use database to check validity in this case every id is valid
}
private function getTitle()
{
//id should be good to use at this point
//get title using database
return $this->seoUrl('How you react of crying babies will determine their future.'); //made up title
}
private function seoUrl($string)
{
//source: http://stackoverflow.com/a/11330527/1564365
//Lower case everything
$string = strtolower($string);
//Make alphanumeric (removes all other characters)
$string = preg_replace("/[^a-z0-9_\s-]/", "", $string);
//Clean up multiple dashes or whitespaces
$string = preg_replace("/[\s-]+/", " ", $string);
//Convert whitespaces and underscore to dash
$string = preg_replace("/[\s_]/", "-", $string);
return $string;
}
}
/* End of file blog.php */
/* Location: ./application/controllers/blog.php */
就是这样,现在创建自己的模型,可以验证ID,抓住标题......
示例代码(模型):
public function isInDb($table, $where = array())
{
$q = $this->db->get_where($table, $where);
return ($q->num_rows() > 0) ? true : false; //returns either true or false, pretty straight forward
}
public function getColumn(){}
现在您使用(生成)网址www.example.com/1
(这会将301标头重定向到/1/title
),或者您可以使用(生成)www.example.com/1/title
链接,但是如果您生成网址如下: /1/fake-title
(标题对于ID 1无效,它不会重定向到正确的标题)
此解决方案对SEO友好。
