How to redirect successful form submission to another page in PHP [duplicate]

Answer 1

Easy! Just use the PHP header function like so. Just be sure to replace the value of success.php with the actual final location you want users to end up in:

//try to send a message     
if(mail(MY_EMAIL, EMAIL_SUBJECT, setMessageBody($fields_req), "From: $email")) {
  // echo json_encode(array('message' => 'Your message was successfully submitted.'));
  header('Location: success.php');
  exit;
} else {
  header('HTTP/1.1 500 Internal Server Error');
  echo json_encode(array('message' => 'Unexpected error while attempting to send e-mail.'));
}

You can also set the specific HTTP response code by changing this:

header('Location: success.php');

To this:

header('Location: success.php', false, 200);

The 200 response code means “OK” which means the page will be loaded as expected; 100% OK. But you might want to change that to 302 which means the URL has moved temporarilly.

Answer 2

You can simple use header function:

Success case:

Header('location:success.php');

Error case:

Header('location:error.php');
