problem retrieving uri segments using $this->uri->segment()

[eluser]mobilizedesign[/eluser]
when i try to assign a value to a variable like this ...

$variable = $this->uri->segment(n);

i get nothing. when i make a slight change ...

$variable = $this->uri->segment(n,0);

i get the FALSE value ( 0 in this case )

my nav links are setting the uri like this ... http://www.domain.com/codeigniter/index....lections/n

why am i unable to access uri using segments()? is this related to the routes.php file?

is $this->uri->segment(n,0) incompatible when using QUERY_STRING config?

changed the $config['uri_protocol'] to

Code:

$config['uri_protocol']    = "REQUEST_URI";

now segment() is behaving

If you are using re-reouted URI you have to use:

Code:

$this->uri->rsegment(n)

not

Code:

$this->uri->segment(n)

URI class is not compatible with QUERY_STRING
