Codeigniter 使用额外的 url 参数

Question

In codeigniter I want to have one url segment to not be consider.

example.com/app/dev1/controller/function/id
example.com/app/dev2/controller/function/id

base url is

baseUrl = example.com/app

When I use this type of url, codeigniter consider "dev1" as controller, "controller" as function, so I get error of page not found.

I want to know if I can code which don't consider first parameter as controller and it start considering from second parameters.

I can not add in base url as it is not constant we can have en, fr, nl etc so do we have anything that help in this case I don't want to add query string "?". Can we do anything using .htaccess

Answer 1

suppose url is like following : www.paintes.com/painters-in-chennai then route can be like following

    $route['painters-in-(:any)'] ='index/paintersIn/$1';

in index.php controller, i'll be able to receive chennai like following

    function paintesIn($city_name)
    {
        echo $city_name //OUTPUT WILL BE "chennai"
    }

if url is like www.paintes.com/painters-in-mumbai , then output will be mumbai

as per your request, URL is liek following : www.paintes.com/mumbai-painters then you can write like following

    $route['(:any)-painters'] ='index/paintersIn/$1';

You have to configure your CodeIgniter routes properly. Example:

$route['dev1/controller/fun/(:num)']  = "dev1/controller/fun/index/$1";

See https://blog.biernacki.ca/2011/12/codeigniter-uri-routing-issue-with-controller-folders/

Answer 3

You could add a URI Routing regular expression like this to skip the dev part and go straight to the desired controller :

$route['dev(:num)/([a-z]+)/([a-z]+)/(\d+)'] = '$2/$3/$4'; // rule to match method with parameter
$route['dev(:num)/([a-z]+)/([a-z]+)'] = '$2/$3'; // rule to match method without parameter

Or if you don have a common dev URI segment, you could use :any rule :

$route['(:any)/([a-z]+)/([a-z]+)/(\d+)'] = '$2/$3/$4'; // rule to match method with parameter
$route['(:any)/([a-z]+)/([a-z]+)'] = '$2/$3'; // rule to match method without parameter

Answer 4

You might want to go for the following in routing

$route['dev1/(:any)'] ='dev1/$1';
$route['dev1/(:any)/(:any)'] ='dev1/$1/$2';
$route['dev1/(:any)/(:any)/(:any)'] ='dev1/$1/$2/$3';

Its rare that Codeigniter treats folder name as controller, try renaming folderas well.

Otherwise above solution should work.

we will neeed to create new file "MY_Router.php" in "/application/core" folder, with following content

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

class MY_Router extends CI_Router {

 protected function _parse_routes()
 {
    // do logic you needed

    unset($this->uri->segments[1]);

    // Return default function
    return parent::_parse_routes();
 }  
}
