questa è la pagina nella quale ho un form per inviare email:
Codice PHP:
<?php
require 'class.mail.php';

if (isset($_POST['send'])) {
    require_once 'control.php';

    $errori = validate_field($_POST['from_address'], $_POST['message']);

    if (empty($errori)) {
        $from = $_POST['from_address'];
        $cc = $_POST['cc_address'];
        $subj = $_POST['subject'];
        $text = $_POST['message'];

        $mail = new mail_og();
        $mail->setToAddress('email');
        $mail->setFromAddress($from);
        $mail->setCcAddress($cc);
        $mail->setSubject($subj);
        $mail->setTextBody($text);

//        if ($mail->send()) {
//            echo "

Il messaggio è stato inviato

";
//            echo "[b]From:[/b] " . $_POST['from_address'] . "
";
//            echo '[b]CC:[/b] ' . $_POST['cc_address'] . "
";
//            echo "[b]Subject:[/b] " . $_POST['subject'] . "
";
//            echo "[b]Message:[/b]</p>";
//            echo nl2br($_POST['message']);
//            echo '
Tra 5 secondi sarai reindirizzato nella home page.';
//            header('refresh: 5; url=index.html');
//        }
    }
} else if (isset($errori)) {
    if (!empty($array_errori)) {
        echo 'Si sono verificati i seguenti errori:
';
        foreach ($errori as $key => $value) {
            echo '-' . '[b]' . $value . '[/b]' . '
';
        }
    }
}

il file control.php è questo:

        return "Nessuna Email inserita
";
    } else if (!((strpos($field, ".") > 0) && (strpos($field, "@") > 0)) || preg_match("/[^a-zA-Z0-9.@_-]/", $field)) {
        return "L'indirizzo Email è invalido
";
    }
    return "";
}

function validate_field($text, $email) {
    $email = trim($email);
    $error = array();
    if (valida_text($text) != '') {

    }

        $error[] = valida_email($email);
    }
}

nn funziona.
se lascio tutti i campi vuoti e clicco su send nn succede nulla mentre mi dovrebbe restituire un errore.
nn riesco a capire dove sbaglio!
