[enrico16101990]

Salve ragazzi, non riesco a far usire il valore di <?php echo $id; ?>.
come mai?

                <?php
session_start();
require_once('lib/Users.class.php');
$login = New Users;
?>
                
    <?php if($login->is_logged()) : ?>
    <div id="contenuti_protetti">
                
                
                <?php
include('connect-db.php');
$numero = $login->get_id();
$result = mysql_query("SELECT * FROM users where id=$numero")
or die(mysql_error()); 
echo "<table border='1' cellpadding='10'>";
while($row = mysql_fetch_array( $result )) {
}
?>
                
                
                
              <form name="modulo" id="modulo" onSubmit="return controllo();" method="post" action="invio.php"> 






<p><strong>ID: <span class="style1">*</span></strong><BR><input type="text" name="id" id="id" value="2"/>
  </BR>
                  <strong>Riferimento Mittente: <span class="style1">*</span></strong>
                    <BR><input type="text" name="riferimento" id="riferimento" value="<?php echo $id; ?>"/>
  </BR>
                  <strong>Telefono Mittente: <span class="style1">*</span></strong>
                    <BR><input type="text" name="cell_1" id="cell_1"/>
  


</form>
            
    </div>
