[solved - thanks!] $this->uri->rsegment(x) in a hook?

[eluser]Tim Skoch[/eluser]
I'm trying to use the URI class in a pre-controller hook, but whenever I do, I get the following PHP error:

Fatal error: Using $this when not in object context in /path/to/my/ci/installation/system/application/hooks/login.php on line 3

My call from within the hook is as follows:
echo($this->uri->rsegment(1));

(bad form, I know, echoing output before headers are sent. But I'm just troubleshooting right now...)

All I need to obtain is the first segment of the URI after it has been routed.

Code:

$URI =& load_class('URI');

To get the segments i suggest you use a post_controller_constructor hook because the super object isn't defined yet when executing pre_controller hooks. You can get the segments but then you have to use this

Code:

$URI =& load_class('URI');
echo $URI->rsegment(1);

The core classes are loaded but they are just a bunch of classes before the controller is loaded.

edit : wiredesignz beat me

Thanks guys! Your suggestion worked great. I've outlined what I was working on in the following post, hoping to attract some constructive criticism.
