Redirect custom url with get method

In my encoder application / helper / MY_url_helper I would like to be able to add '?&route=' . $uri

I would like to be able to use my '?&route='

after index.php, but before the first folder / function.

But every time I click on the link the URL changes but the page stays the same?

Question: On my helper, how can I add '?&route=' . $uri

but make it still redirected to the page currently every time, even when I click the link, the url changes, but the page stays the same?

redirect('common/dashboard');

Url http://localhost/project/admin/?&route=common/dashboard

I tried it with routes and the same problem.

<?php

if ( ! function_exists('redirect'))
{
function redirect($uri = '', $method = 'auto', $code = NULL)
{
    //if ( ! preg_match('#^(\w+:)?//#i', $uri))
    //{
        $uri = site_url('?&route=' . $uri);
    //}

    // IIS environment likely? Use 'refresh' for better compatibility
    if ($method === 'auto' && isset($_SERVER['SERVER_SOFTWARE']) && strpos($_SERVER['SERVER_SOFTWARE'], 'Microsoft-IIS') !== FALSE)
    {
        $method = 'refresh';
    }
    elseif ($method !== 'refresh' && (empty($code) OR ! is_numeric($code)))
    {
        if (isset($_SERVER['SERVER_PROTOCOL'], $_SERVER['REQUEST_METHOD']) && $_SERVER['SERVER_PROTOCOL'] === 'HTTP/1.1')
        {
            $code = ($_SERVER['REQUEST_METHOD'] !== 'GET')
                ? 303   // reference: http://en.wikipedia.org/wiki/Post/Redirect/Get
                : 307;
        }
        else
        {
            $code = 302;
        }
    }

    switch ($method)
    {
        case 'refresh':
            header('Refresh:0;url='.$uri);
            break;
        default:
            header('Location: '.$uri, TRUE, $code);
            break;
    }
    exit;
}
}

      

        
        
        
      

    

.htaccess

Options +FollowSymLinks
Options -Indexes
DirectoryIndex index.php
RewriteEngine on
RewriteCond $1 !^(index\.php|images|robots\.txt)
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^(.*)$ index.php/$1 [L,QSA]

      

        
        
        
      

    

Update:

Codeigniter version using 3

In my configuration, I now use

Tried

$config['uri_protocol'] = 'REQUEST_URI';

and

$config['uri_protocol'] = 'QUERY_STRING';

But then now they say that the page was not found?

The page is there.

Also "shared" will be the folder

And the "dashboard" will be the controller

All controllers have first letter as uppercase Dashboard.php

Note. I tried to include query strings in config.php but doesn't work the way I am following it.
