ciao a tutti
ho un form email jquery/php che funziona perfettamente se apro la pagina contact.php direttamente dal browser;

il tutto con questo codice
Codice PHP:
<?php
//If the form is submitted
if(isset($_POST['submit'])) {

    //Check to make sure that the name field is not empty
    if(trim($_POST['contactname']) == '') {
        $hasError = true;
    } else {
        $name = trim($_POST['contactname']);
    }

    //Check to make sure that the subject field is not empty
    if(trim($_POST['subject']) == '') {
        $hasError = true;
    } else {
        $subject = trim($_POST['subject']);
    }

    //Check to make sure sure that a valid email address is submitted
    if(trim($_POST['email']) == '')  {
        $hasError = true;
    } else if (!eregi("^[A-Z0-9._%-]+@[A-Z0-9._%-]+\.[A-Z]{2,4}$", trim($_POST['email']))) {
        $hasError = true;
    } else {
        $email = trim($_POST['email']);
    }

    //Check to make sure comments were entered
    if(trim($_POST['message']) == '') {
        $hasError = true;
    } else {
        if(function_exists('stripslashes')) {
            $comments = stripslashes(trim($_POST['message']));
        } else {
            $comments = trim($_POST['message']);
        }
    }

    //If there is no error, send the email
    if(!isset($hasError)) {
        $emailTo = 'youremail@yoursite.com'; //Put your own email address here
        $body = "Name: $name \n\nEmail: $email \n\nSubject: $subject \n\nComments:\n $comments";
        $headers = 'From: My Site <'.$emailTo.'>' . "\r\n" . 'Reply-To: ' . $email;

        mail($emailTo, $subject, $body, $headers);
        $emailSent = true;
    }
}
?>

</div>
</div>
</body>
</html>
se invece la pagina la richiamo dall'index con questo metodo:
http:/.../index.php?sez=contact
al momento dell'invio mi rimanda all'index
di sicuro ho capito che il problema è qui perchè la pagina con il form richiamato senza questa funzione funziona solo che a me servirebbe così

grazie a tutti
ciao!
