way to have php header open same page but showing a hidden div? -


apologies if has been asked before, working on first site , still learning. trying add captcha contact form taken here http://www.captcha.net/ , using php. @ moment working, code supplied on site work follows:

  <html>     <body> <!-- body tag required or captcha may not show on browsers -->       <!-- html content -->        <form method="post" action="verify.php">         <?php           require_once('recaptchalib.php');           $publickey = "your_public_key"; // got signup page           echo recaptcha_get_html($publickey);         ?>         <input type="submit" />       </form>        <!-- more of html content -->     </body>   </html>

and verify code on different file (server side) is:

  <?php   require_once('recaptchalib.php');   $privatekey = "your_private_key";   $resp = recaptcha_check_answer ($privatekey,                                 $_server["remote_addr"],                                 $_post["recaptcha_challenge_field"],                                 $_post["recaptcha_response_field"]);    if (!$resp->is_valid) {     // happens when captcha entered incorrectly     die ("the recaptcha wasn't entered correctly. go , try again." .          "(recaptcha said: " . $resp->error . ")");   } else {     // code here handle successful verification   }   ?>

what wondering if there way have if statement (if captcha wrong) open contact page show hidden div displaying captcha code wrong , try again.

in case, can try way:

verify.php

if (!$resp->is_valid) {     header("location: contact.php?show-error"); // replace file name     exit; } else {     // code here handle successful verification }

contact.php

if(isset($_get['show-error'])){     echo "<div>         recaptcha wasn't entered correctly.          go , try again.     </div>"; }

or:

<div style="display:<?php echo isset($_get['show-error']) ? "block" : "none"; ?>">     recaptcha wasn't entered correctly.      go , try again. </div>

but in case, think it's better move verify code contact page. can easy decide show message depend on if condition.
