How To Use ReCaptcha

To make the reCAPTCHA widget appear when your page loads, you will need to insert this snippet of JavaScript & non-JavaScript code in your <form> element and replace your_public_key with your public key:



<script type="text/javascript"
     src="http://www.google.com/recaptcha/api/challenge?k=your_public_key">
  </script>
  <noscript>
     <iframe src="http://www.google.com/recaptcha/api/noscript?k=your_public_key"
         height="300" width="500" frameborder="0"></iframe><br>
     <textarea name="recaptcha_challenge_field" rows="3" cols="40">
     </textarea>
     <input type="hidden" name="recaptcha_response_field"
         value="manual_challenge">
  </noscript>


So your page will look something like this:


<!-- ... your HTML content ... -->

  <form action="" method="post">

    <!-- ... your form code here ... -->

    <script type="text/javascript"
       src="http://www.google.com/recaptcha/api/challenge?k=your_public_key">
    </script>
    <noscript>
       <iframe src="http://www.google.com/recaptcha/api/noscript?k=your_public_key"
           height="300" width="500" frameborder="0"></iframe><br>
       <textarea name="recaptcha_challenge_field" rows="3" cols="40">
       </textarea>
       <input type="hidden" name="recaptcha_response_field"
           value="manual_challenge">
    </noscript>

    <!-- ... more of your form code here ... -->

  </form>


  <!-- ... more of your HTML content ... -->
