İzlediğim kodu doğrulamak gerekir ve aynı zamanda myemail.com e-posta gönderir, php kodu kullanarak e-posta göndermek istiyorum. Ancak, çalışmıyor.

Ben php yeni duyuyorum. herhangi bir yardım mutluluk!!

// EDIT THE 2 LINES BELOW AS REQUIRED
$email_to = "myemail@gmail.com";
$email_subject = "Subject here...";


function died($error) {
    // your error code can go here
    echo "We are very sorry, but there were error(s) found with the form your submitted. ";
    echo "These errors appear below.<br /><br />";
    echo $error."<br /><br />";
    echo "Please go back and fix these errors.<br /><br />";
    die();
}

// validation expected data exists
if(!isset($_POST['first_name']) ||
    !isset($_POST['email']) ||
    ) {
    died('We are sorry, but there appears to be a problem with the form your submitted.');      
}

$first_name = $_POST['first_name']; // required
$last_name = $_POST['email']; // required

$error_message = "";
$email_exp = "^[A-Z0-9._%-]+@[A-Z0-9.-]+\.[A-Z]{2,4}$";
  if(!eregi($email_exp,$email_from)) {
    $error_message .= 'The Email Address you entered does not appear to be valid.<br />';
  }
    $string_exp = "^[a-z .'-]+$";
  if(!eregi($string_exp,$first_name)) {
    $error_message .= 'The First Name you entered does not appear to be valid.<br />';
  }
    $email_message = "Email body here......\n\n";



// create email headers
$headers = 'From: '.$email_from."\r\n".
'Reply-To: '.$email_from."\r\n" .
'X-Mailer: PHP/' . phpversion();
@mail($email_to, $email_subject, $email_message, $headers);  
?>
