Aiuto per registrazione utente

[danilob]

Ciao a tutti....

quando cerco di inserire un nuovo utente nel database sample_db con la procedura riportata sotto, non succede nulla. Non capisco dove sbaglio, lo script dovrebbe creare all'interno della stessa pagina una tabella con i dati della registrazione appena effettuata ma, non fa nulla. Non so + cosa fare....

ecco lo script e grazie a tutti!

<?php
//register.php
include_once "./common_db.inc";

function in_use($userid) {
global $user_tablename;

$query = "SELECT userid FROM $user_tablename WHERE userid = '$userid'";
$result = mysql_query($query);
if(!mysql_num_rows($result)) return 0;
else return 1;
}

function register_form() {
global $userposition;
global $PHP_SELF;

$link_id = db_connect();
mysql_select_db("sample_db");
$position_array = enum_options('userposition', $link_id);
mysql_close($link_id);

?>
