Avrei un problemino ....

Sto creando un sito in php dove,quando l'utente si logga,tenendo conto della tabella in db mysql e nello specifico del numero ID_utente,volevo indirizzare ognuno verso un link diverso..ma ho dei problemi
Il codice e' questo ,chi puo' dirmi dove sbaglio:

PHP:
<?php
    
    if($id_user = 1){ 
    
    
 Echo "<a href=/id_user1/upload.php>CARICA I TUOI FILE!</a>" ; 

    
    } elseif ( $id_user = 2 ){
    
    
 Echo "<a href=/id_user2/upload.php>CARICA I TUOI FILE!</a>" ,
}

           } elseif ($id_user = 3 ){
    
    
             Echo "<a href=/id_user3/upload.php>CARICA I TUOI FILE!</a>"; 
            }      



?>

Grazie in anticipo a tutti
 
Ciao, per paragonare due valori si usa il doppio uguale (==)
avevi una graffa e una virgola in piu
PHP:
<?php

if ($id_user == 1) {
    echo "<a href=/id_user1/upload.php>CARICA I TUOI FILE!</a>";
} elseif ($id_user == 2) {
    echo "<a href=/id_user2/upload.php>CARICA I TUOI FILE!</a>";
} elseif ($id_user == 3) {
    echo "<a href=/id_user3/upload.php>CARICA I TUOI FILE!</a>";
}
?>
in ogni caso ti conviene scrivere semplicemente cosi
PHP:
<?php
echo "<a href='/id_user" . $id_user . "/upload.php'>CARICA I TUOI FILE!</a>";
?>
edit
mancano anche gli apici nel link
PHP:
<a href='/id_user3/upload.php'>
 
Ultima modifica:
grazie mille criric
.....ma forse non mi sono spiegato bene
Io vorrei che se si loga "pinkopallo" , lo stesso deve vedere solo il suo link verso la sua pagina privata
invece cosi
PHP:
if ($id_user == 1) {
    echo "<a href=/id_user1/upload.php>CARICA I TUOI FILE!</a>";
} elseif ($id_user == 2) {
    echo "<a href=/id_user2/upload.php>CARICA I TUOI FILE!</a>";
} elseif ($id_user == 3) {
    echo "<a href=/id_user3/upload.php>CARICA I TUOI FILE!</a>";
}
vede tutti e tre i link e non va bene....
Sto impazzendo...
 
guarda che in entrambe le soluzioni che ti ho postato vedi solo un link
forse hai trascritto male
ricordati di mettere gli apici
 
Scusa ma sono alle prime armi
Cosi va bene?per ora ho solo 3 utenti:
PHP:
echo "<a href='/id_user1" . $id_user . "/upload.php'>CARICA I TUOI FILE!</a>";
echo "<a href='/id_user2/" . $id_user2 . "/upload.php'>CARICA I TUOI FILE!</a>";
echo "<a href='/id_user3/" . $id_user3 . "/upload.php'>CARICA I TUOI FILE!</a>";

solo che nella pagina ,quando entri si vedono 3 link...non va'
 
ma non è quello che abbiamo scritto
dove prendi queste variabili $id_user , $id_user2 e $id_user3 ?
il login come lo fai?
 
Login.php
PHP:
<?PHP
require_once("./include/membersite_config.php");


if(isset($_POST['submitted']))
{
   if($fgmembersite->Login())
   {
        $fgmembersite->RedirectToURL("login-home.php");
   }
}

?>

tutte quelle variabili le prendo guardando il mio database mysql dove ,per ora,ho 3 utenti,e quindi id_user1,id_user2 etc
come posso risolvere?
 
in pratica quando effettui il login finisci in LOGIN-home.php e qui dovresti trovare il tuo link che ti indirizza alla tua cartella gia preparata distinta da quella degli altri utenti:
link->CARTELLA1 se si logga UTENTE1
link->CARTELLA2 se si logga UTENTE2

e cosi via..........
 
la vedo ardua
il tutto cmq dovrebbe essere dentro questo file : membersite_config.php
puoi postarlo?
 
eccolo
PHP:
<?PHP
require_once("./include/fg_membersite.php");

$fgmembersite = new FGMembersite();

//Provide your site name here
$fgmembersite->SetWebsiteName('CarpeWeb.altervista.org');

//Provide the email address where you want to get notifications
$fgmembersite->SetAdminEmail('carpeweb@altervista.org');

//Provide your database login details here:
//hostname, user name, password, database name and table name
//note that the script will create the table (for example, fgusers in this case)
//by itself on submitting register.php for the first time
$fgmembersite->InitDB(/*hostname*/'localhost',
                      /*username*/'usrname',
                      /*password*/'password',
                      /*database name*/'my_db',
                      /*table name*/'fgusers3');

//For better security. Get a random string from this link: [url]http://tinyurl.com/randstr[/url]
// and put it here
$fgmembersite->SetRandomKey('qSRcVS6DrTzrPvr');

ma dove l'hai trovato?
non ti conveniva qualcosa di piu semplice visto che sei all'inizio

sicuro che ci sia l'id nella tabella utenti ?
in questo caso ti conviene mettere in sessione anche l'id e cambiare questa funzione
PHP:
function CheckLoginInDB($username, $password) {
        if (!$this->DBLogin()) {
            $this->HandleError("Database login failed!");
            return false;
        }
        $username = $this->SanitizeForSQL($username);
        $pwdmd5 = md5($password);
        $qry = "Select name, email from $this->tablename where username='$username' and password='$pwdmd5' and confirmcode='y'";

        $result = mysql_query($qry, $this->connection);

        if (!$result || mysql_num_rows($result) <= 0) {
            $this->HandleError("Error logging in. The username or password does not match");
            return false;
        }

        $row = mysql_fetch_assoc($result);


        $_SESSION['name_of_user'] = $row['name'];
        $_SESSION['email_of_user'] = $row['email'];

        return true;
    }

dove cambierai la select aggiungendo il nome del campo dell'id e metterai in sessione il risultato della query
PHP:
 $_SESSION['id_of_user'] = $row['nome_campo_id_utente'];
dopodiche ti basta scrivere cosi
PHP:
echo "<a href='/id_user" . $_SESSION['id_of_user'] . "/upload.php'>CARICA I TUOI FILE!</a>";
 
questa e' la tabella

$qry = "Create Table $this->tablename (".
"id_user INT NOT NULL AUTO_INCREMENT ,".
"name VARCHAR( 128 ) NOT NULL ,".
"email VARCHAR( 64 ) NOT NULL ,".
"phone_number VARCHAR( 16 ) NOT NULL ,".
"username VARCHAR( 16 ) NOT NULL ,".
"password VARCHAR( 32 ) NOT NULL ,".
"confirmcode VARCHAR(32) ,".
"PRIMARY KEY ( id_user )".
")";

quindi che faccio?
 
cambia la funzione cosi
PHP:
function CheckLoginInDB($username, $password) {
        if (!$this->DBLogin()) {
            $this->HandleError("Database login failed!");
            return false;
        }
        $username = $this->SanitizeForSQL($username);
        $pwdmd5 = md5($password);
        $qry = "Select id_user, name, email from $this->tablename where username='$username' and password='$pwdmd5' and confirmcode='y'";

        $result = mysql_query($qry, $this->connection);

        if (!$result || mysql_num_rows($result) <= 0) {
            $this->HandleError("Error logging in. The username or password does not match");
            return false;
        }

        $row = mysql_fetch_assoc($result);


        $_SESSION['name_of_user'] = $row['name'];
        $_SESSION['email_of_user'] = $row['email'];
        $_SESSION['id_of_user'] = $row['id_user'];

        return true;
    }
e metti il link come te l'ho postato prima
 
PHP:
echo "<a href='/id_user" . $_SESSION['id_of_user'] . "/upload.php'>CARICA I TUOI FILE!</a>";
nella pagina dove vuoi che l'utente veda il link
 
ho fatto tutto cio che mi hai suggerito
ma il link mi porta in./id_user/upload
le cartelle assegnate ad ogni utente si chiamano
id_user1
id_user2
etc..etc
 
per capire il lavoro di stasera non mi basterebbero 10 anni forse...
quindi ti ringrazio moltissimo x per la disponibilita'....
