Codeigniter Routes regex - using dashes in controller/method names

Question

I\'m looking for a one line route to route dashed controller and method names to the actual underscored controller and method names.

For example the URL

Answer 1

I'm not sure if you could do that with a route...

However, somewhere in the Codeigniter core libraries (possibly Router or URI) will be something that converts the underscored uris into a camelcase class name.

I had a quick look and couldn't find it, but if you do, just copy that library to your application/libraries folder, and modify it there.

Answer 2

Just coming back to this question after upgrading to CodeIgniter 2. Here is a solution which is more robust than the accepted answer because it will survive CodeIgniter core updates.

<?php
class MY_Router extends CI_Router
{ 
    public function set_class($class) 
    {
        parent::set_class($this->_repl($class));
    }

    public function set_method($method) 
    {
        parent::set_method($this->_repl($method));
    }

    public function _validate_request($segments)
    {
        if (isset($segments[0]))
            $segments[0] = $this->_repl($segments[0]);
        if (isset($segments[1]))
            $segments[1] = $this->_repl($segments[1]);

        return parent::_validate_request($segments);
    }

    private function _repl($s)
    {
        return str_replace('-', '_', $s);
    }
}

It should be saved as application/core/MY_Router.php. Now, you can have Controller and Method names with underscores in them such as Abc_Def (in file abc_def.php) and refer to them with the URL /abc-def.

Answer 3

This is an old question, but I'd like to post that e-mike had a great solution to this problem, and a lot simpler.

<?php
    public function _set_request($segments){
        // Fix only the first 2 segments
        for($i = 0; $i < 2; ++$i){
            if(isset($segments[$i])){
                $segments[$i] = str_replace('-', '_', $segments[$i]);
            }
        }

        // Run the original _set_request method now, giving it our newly replaced segments
        parent::_set_request($segments);
    }
?>

Hope this helps anyone else with this problem.
