How do I retrieve a uri segment in a hook?

Hmm, that means that it works but that the URI hasn't been parsed yet (and thus segment() returns FALSE). The result is that CURRENT_LANGUAGE is set to FALSE which probably causes the white-screen error later on (because it's expected to be a string).

Here's another thing that might work in its stead:

Code:

$segment = substr( load_class('URI')->_parse_request_uri(), 1);
$segment = array_shift( explode( '/', $segment ) ); // takes the first segment
define( 'CURRENT_LANGUAGE', $segment );
