php - How to display a recaptcha error within the submitted form's page? -


i using recaptcha widget on contact form, wondering how able display error user gets on same page instead of going page , displaying error.

you can put form submit on same page, , check post data on php side. check example:

<?php  $captcha = $_post['captcha']; if(isset($captcha)) {   $captcha_answer = // need put correct captcha answer here   if($captcha == $captcha_answer) {       // captcha correct, continue.   }   else {       // captcha not correct, display error message.       echo '<div style="background-color:red; padding:3px;">your captcha not correct, please try again.</div>';       echo '<form method="post">                 <input type="text" name="captcha" value="type captcha here" />             </form>'; // print page again   } } else { ?>  <form method="post">     <input type="text" name="captcha" value="type captcha here" /> </form>  <?php } ?>

another option use javascript ajax.
