reCAPTCHA: Go back hyperlink

[Jacques2012]

I'd like to add a go back / return to previous page hyperlink should the reCAPTCHA validation fail due to input errors by the user. Can the form data be retained?
*Thanks for the PHP Login Script.*

You can simply redirect the error action to a new page like error.php by adding a header location marked in blue color.

require_once('recaptchalib.php');
     
      $resp = recaptcha_check_answer ($privatekey,
                                      $_SERVER["REMOTE_ADDR"],
                                      $_POST["recaptcha_challenge_field"],
                                      $_POST["recaptcha_response_field"]);

if (!$resp->is_valid) { 
header('Location: error.php'); 
exit();  
}

and then you can create a link or form to get back to the registration page.

Thanks to the developers of this script.

Solved: register.php code changed as advised and error.php page created with a go back hyperlink and instructions for user. Thanks!
