problem with posting a var

[eluser]Lacsap[/eluser]
Hello.

Im using Jquery and Autocomplete. It works well if i manage the $_GET['q'] sended by jqeury in a file wich is not in the codeigniter framework.

if i try to manage this var in codeigniter im getting an error:

A PHP Error was encountered

Severity: Notice

Message: Undefined index: q

Filename: controllers/test.php

Line Number: xx

line number xx is just:

Code:

echo $_GET['q'];

if i write on line xx

Code:

echo 'test';

it works.

Just if i try to handle the sended var q, im getting error :-( Why?

Thanks
