So what is the problem? Data is not inserted or you php code gives error?

P.S. Your code is VERY insecure! Please do at least any input data validation and sanitization.

How do you receive the data via form. I see no '$_POST' or '$_GET' or '$_REQUEST'. You wouldn't get any data if you are using the form.

$query = "INSERT INTO vartotojai SET vardas = '$vardas', slaptazodis = '$slaptazodis', el_pastas = '$el_pastas', avataras = '$avataras', parasas = '$parasas'";

Where are '$vardas,$slaptazodis,$el_pastas,$avataras,$parasas' come from ? You must use '$_POST[]' (for post method), '$_GET[]' (for get method), or '$_REQUEST[]' (for both post and get).
It may like:

$vardas = $_POST['vardas'];
$slaptazodis = $_POST['slaptazodis'];
$el_pastas = $_POST['el_pastas'];
$avataras = $_POST['avataras'];
$parasas = $_POST['parasas'];

 if($vardas != "" && $slaptazodis != "" && $el_pastas != ""){
        $query = "INSERT INTO vartotojai SET vardas = '$vardas', slaptazodis = '$slaptazodis', el_pastas = '$el_pastas', avataras = '$avataras', parasas = '$parasas'";
        mysql_query($query);
}

Hope this help.

you see at the beginning include("config.php");
inside config is this
$id = $_GET;
$vardas = $_POST;
$el_pastas = $_POST;
$slaptazodis = $_POST;
$avataras = $_POST;
$parasas = $_POST;
$character = $_POST;

and also i need the last one not the one that you fixed :)
