Database driven routes in CodeIgniter

[eluser]Unknown[/eluser]
Hello,

I am using this piece of code and I want to extend it. But I need now a config variable in the Router_Hook.php.
To do this, I thought I do the same as with the database variables:

So in the hook.php file I added the following:

Code:

require_once BASEPATH."application/config/config.php";

And I thought now I can access all the config variables. But it isn't!

if I do for example:

Code:

echo $config['base_url'];

in the hook.php file. It seems that this variable is empty. if I print the config array I don't see the content. Even not Array( ).

What is going wrong?
(I'm new to CodeIngiter)

Thanks,
Kristof
