Triggering reCaptcha in a form

the question:  how trigger recaptcha mechanism, in standard form?

 

the setting:  recaptcha has been set precisely laid out on google's recaptcha pages, in case using formmail.pl script handle form.  formmail perl script performs flawlessly, email filled-in form data (to email, rather insert database).

 

however - though set according spec - missing trigger recaptcha mechanism.  form ‘submit,’ without accounting whether recaptcha fields filled in.  recaptcha not kick in, ‘wait minute, have not filled in test field.’

 

(the page current code @ http://concord-trustingtheprocess.org .  can see, spry forms validation mediates user entries individual form fields.  problem lies in triggering recaptcha part.  said, necessaries, recaptcha, in formmail perl script.)

 

an additional issue of course - in case of user’s failing make correct entry recaptcha - re-population of page, try.

 

is php, or javascript, required, finish off?  if so, can specified succinctly?  , if so, thanks.

 

currently relevant html has recaptcha code , submit button in simple side-by-side cells of one-row table [the public key has been replaced here placeholder]:

 

  </table>

  <table width="567" border="0" align="center" cellpadding="0" cellspacing="0">

    <tr align="left" valign="middle"">

      <td>

 

        <script type="text/javascript"

    src="http://www.google.com/recaptcha/api/challenge?k=[my_public_key]">

  </script>

        <noscript id="recaptcha_area">

          <iframe src="http://www.google.com/recaptcha/api/noscript?k=[my-public_key]"

        height="300" width="500" frameborder="0"></iframe>

         

          <textarea name="recaptcha_challenge_field" rows="3" cols="40">

              </textarea>

          <input type="hidden" name="recaptcha_response_field"

        value="manual_challenge">

          </noscript>

 

                    </td>

                    <td><input type="submit" name="button" id="button" value="submit" /></td>

      </tr>

  </table>

 

 

css added facilitate page layout, not relevant problem:

#recaptcha_area #recaptcha_response_field {

    position: static !important;

}

 

i have done pretty thorough search on subject, in our community forum here; without real success (did miss it?)  posting detail, , query.

 

thanks in advance help,  david allen
