Case Insensitive Routing in CodeIgniter

Question

I\'ve written this in the CodeIgniter\'s routers.

$route[\'companyname\'] = \"/profile/1\";

This is working fine but when I type \"CompanyN

Answer 1

Uhm, well, an dirty but straight to the point way would be to make a small hack to the core Uri class. Open the uri.php file inside system/core/ , scroll to line 269 where you have the method _explode_segments() and make them lowercase. Bad method, but should work.

function _explode_segments()
{
    foreach (explode("/", preg_replace("|/*(.+?)/*$|", "\\1", $this->uri_string)) as $val)
    {
        // Filter segments for security
        $val = trim($this->_filter_uri($val));

        if ($val != '')
        {
                    // $this->segments[] = $val;  // <--- ORIGINAL
            $this->segments[] = strtolower($val);   // <--- CHANGED
        }
    }
}  

Just consider that if you upgrade your install this changes will be overwritten, but they're so small anyway. Alternatively, you might go for a pre_system hook, but I think it would be much more difficult

Also, in routes you should not use leading or trailing slashes, so it must be

$route['companyname'] = "profile/1";

Answer 2

Maybe you can use strtolower in your _remap function. It isn't sure that works, it was just an idea ;)

Answer 3

IN Directory system/core/uri.php

search about

$this->_parse_request_uri()

you will find 2 replace them with

strtolower($this->_parse_request_uri())

Answer 4

The easiest way I could think of is to enforce lowercase urls with mod_rewrite (if you're using apache...)

RewriteMap  lc int:tolower
RewriteCond %{REQUEST_URI} [A-Z]
RewriteRule (.*) ${lc:$1} [R=301,L]

Answer 5

Just add expression "(?i)"
Here example:
$route['(?i)companyname'] = "/profile/1";

Answer 6

Use Router:

$urix = substr(strtolower($_SERVER['REQUEST_URI']), 1);

$route["(?i)$urix"] = $urix;
