Ciao a tutti,
ho provato lo script, prima versione, di un articolo su la "Gestione degli utenti" in php.
Nemmeno il gusto di visualizzare la prima pagina.....
lo script:
<?php
$_AUTH = array(
"TRANSICTION METHOD" => AUTH_USE_COOKIE
);
function auth_set_option($opt_name, $opt_value){
global $_AUTH;
$_AUTH[$opt_name] = $opt_value;
}
function auth_get_option($opt_name){
global $_AUTH;
return is_null($_AUTH[$opt_name])
? NULL
: $_AUTH[$opt_name];
}
function auth_clean_expired(){
global $_CONFIG;
$result = mysql_query("SELECT creation_date FROM ".$_CONFIG['table_sessioni']." WHERE uid='".auth_get_uid()."'");
if($result){
$data = mysql_fetch_array($result);
if($data['creation_date']){
if($data['creation_date'] + $_CONFIG['expire'] <= time()){
switch(auth_get_option("TRANSICTION METHOD")){
case AUTH_USE_COOKIE:
setcookie('uid');
break;
case AUTH_USE_LINK:
global $_GET;
$_GET['uid'] = NULL;
break;
}
}
}
}
mysql_query("
DELETE FROM ".$_CONFIG['table_sessioni']."
WHERE creation_date + ".$_CONFIG['expire']." <= ".time()
);
}
function auth_get_uid(){
$uid = NULL;
switch(auth_get_option("TRANSICTION METHOD")){
case AUTH_USE_COOKIE:
global $_COOKIE;
$uid = $_COOKIE['uid'];
break;
case AUTH_USE_LINK:
global $_GET;
$uid = $_GET['uid'];
break;
}
return $uid ? $uid : NULL;
}
function auth_get_status(){
global $_CONFIG;
auth_clean_expired();
$uid = auth_get_uid();
if(is_null($uid))
return array(100, NULL);
$result = mysql_query("SELECT U.name as name, U.surname as surname, U.username as username
FROM ".$_CONFIG['table_sessioni']." S,".$_CONFIG['table_utenti']." U
WHERE S.user_id = U.id and S.uid = '".$uid."'");
if(mysql_num_rows($result) != 1)
return array(100, NULL);
else{
$user_data = mysql_fetch_assoc($result);
return array(99, array_merge($user_data, array('uid' => $uid)));
}
}
function auth_login($uname, $passw){
global $_CONFIG;
$result = mysql_query("
SELECT *
FROM ".$_CONFIG['table_utenti']."
WHERE username='".$uname."' and password=MD5('".$passw."')"
);
if(mysql_num_rows($result) != 1){
return array(AUTH_INVALID_PARAMS, NULL);
}else{
$data = mysql_fetch_array($result);
return array(AUTH_LOGEDD_IN, $data);
}
}
function auth_generate_uid(){
list($usec, $sec) = explode(' ', microtime());
mt_srand((float) $sec + ((float) $usec * 100000));
return md5(uniqid(mt_rand(), true));
}
function auth_register_session($udata){
global $_CONFIG;
$uid = auth_generate_uid();
mysql_query("
INSERT INTO ".$_CONFIG['table_sessioni']."
(uid, user_id, creation_date)
VALUES
('".$uid."', '".$udata['id']."', ".time().")
"
);
if(!mysql_insert_id()){
return array(AUTH_LOGEDD_IN, $uid);
}else{
return array(AUTH_FAILED, NULL);
}
}
function auth_logout(){
global $_CONFIG;
$uid = auth_get_uid();
if(is_null($uid)){
return false;
}else{
mysql_query("
DELETE FROM ".$_CONFIG['table_sessioni']."
WHERE uid = '".$uid."'"
);
return true;
}
}
?>
L'errore (sopra in grassetto la linea in questione):
Notice: Undefined index: uid in Z:\Web\Site\SAN\include\auth.lib.php on line 55
......mi aiutate a capirci qualcosa?
Grazie a tutti
