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

Use hooks:

Create application/hooks/LowerUrl.php

class LowerUrl {
    public function run() {
            $_SERVER['REQUEST_URI'] = strtolower($_SERVER['REQUEST_URI']);
    }
}

Add to application/config/hooks.php

$hook['pre_system'] = array(
    'class'    => 'LowerUrl',
    'function' => 'run',
    'filename' => 'LowerUrl.php',
    'filepath' => 'hooks'
);

Answer 2

If you want case-insensitive routing for all routes, you just need to extend CI_Router class, then modify _parse_routes() method like this:

public function _parse_routes()
{
    foreach ($this->uri->segments as &$segment)
    {
        $segment = strtolower($segment);
    }

    return parent::_parse_routes();
}

It will be cleaner than editing the CI_URI class itself. :)
