Codeigniter Make URL SEO FRIENDLY - php

Question

My current URL is like:
www.hostname.com/get_city/
(this url is already shorten by using routes)
Here get_city is my method name and now what i exactly want is...
1)remove controller name from url
2)pass selected city value from dropdown and set in URL as a parameter
So,Required url is: www.hostname.com/california OR www.hostname.com/newjersey
NOTE:I know how to use routes but in such case how to make dynamic URL?!
AND please don't give me direct reference of ellislab docs because i have already tried those things

Answer 1

For dynamic route in codeigniter:
try like this:
in your routes.php file copy and paste these codes:
require_once (BASEPATH . 'database/DB' . EXT);
require_once (BASEPATH . 'helpers/url_helper' . EXT);
require_once (BASEPATH . 'helpers/text_helper' . EXT);
$db = &DB();
$query = $db -> get('news');
$result = $query -> result(); //result return all records
foreach ($result as $row) {
$string = rawurlencode(str_replace(' ', '-', strtolower($row -> subject)));
$route[$string] = "controller/news_details/$row->id";
}
so you can , change $string with any string that you want.
then try type new url and see Routes will work fine.
NOTE:.htaccess file must be removing index.php in url
hope this help.

Answer 2

You can try with the method "_remap".
Check the official documentation for more info about the behavior of the function:

Answer 3

You need to config routes in application/config/routes.php
After existing routes add
$route['([a-z]+)'] = 'controller_name/method_name/$1';
But this overwrite all routes and before this route you need to declare all routes for you controllers
$route['product/:any'] = 'product/$1';
$route['catalog/:any'] = 'catalog/$1';
and after
// this route be used when previous routes is not suitables
$route['([a-z]+)'] = 'controller_name/method_name/$1';
