Support Thread for Google reCAPTCHA plugin

[mikestaps]

Hi Mike
Just had a quick look at it (nice site btw). I think what you need to do is in the class.faq_request.php file:

Add at the beginning of the function update (just after the global $messagestack):

$error=false;
$zco_notifier->notify('NOTIFY_FAQ_CAPTCHA_CHECK');

then change the line 2 below from

if(isset($_POST['email_address']) && !empty($_POST['email_address']) && isset($_POST['fullname']) && !empty($_POST['fullname']) && isset($_POST['message']) && !empty($_POST['message']) && isset($_POST['subject']) && !empty($_POST['subject'])) {

to

if(isset($_POST['email_address']) && !empty($_POST['email_address']) && isset($_POST['fullname']) && !empty($_POST['fullname']) && isset($_POST['message']) && !empty($_POST['message']) && isset($_POST['subject']) && !empty($_POST['subject']) && $error==false) {

in the class.google_recaptcha.php file add (line 23 ish)

$pages_to_check[] =  'NOTIFY_FAQ_CAPTCHA_CHECK';

Hopefully that should sort it - if not I'll have another look

Regards
David

David,
Thanks. I finally got a chance to get back to this (one of the many challenges of being a small business and doing our own site development!). After the changes you suggested are put in place the product info page dies with the following error:
PHP Fatal error: Call to a member function notify() on a non-object in /home3/wwwsica/public_html/store-1st_1-5-4/includes/classes/observers/class.faq_request.php on line 38

That is the $zco_notifier->notify('NOTIFY_FAQ_CAPTCHA_CHECK'); line I added in. I am gong to commect the line out for now intil I can find the solution.
Thanks again

Mike

Ok so I have made a few more attempts at putting this in to the Ajax FAQ module, with no luck. Everything shows, but the check doesn't happen, and the question is sent regardless of the reCaptcha.
Like I said b4 the $zco_notifier->notify('NOTIFY_FAQ_CAPTCHA_CHECK'); inside of the class.faq_request.php kills the page with an error, so I tried moving the notify to the tpl_modules_faq_questions.php file. Top or bottom of the file this didn't work.

Also as this is an ajax pop-up how would I add it to the $event_array line in the class.google_recaptcha.php file?

Thanks for any ideas

mikestaps did you ever get this working on the FAQ page? I'm having a similar problem.

Hi. To fix the $zco_notifier->notify('NOTIFY_FAQ_CAPTCHA_CHECK') error, I think all you need to do is add

global $zco_notofier;

just before it

Hmm I have the code there however it's still ignoring the reCAPTCHA no matter if checked or unchecked. My issue sounded like the same issue as mikestaps was having so I was hopping he resolved it and would share how he was able to make it work.

[mikestaps]

I have not be able to get it fully working, as I had moved this one to the back burner temporarily as I have other upgrades, etc. to make before going live.
Adding the

global $zco_notifier;

fixed that error, but then I found some other issues...
I now having it working, except for the error message when you do not check the "I'm not a robot" box,
It will currently show the "Please fill in the required information and submit it again. Thank you." error, then when you check the box it sends properly.
Almost there...

This is what I have in the class.faq_request.php file:

Thanks for the reply I fixed my issue I had the:

&& $error==false 

in the wrong place.

mikestaps's if you trying to get it to display a messagestack error for example "Please check the the reCAPTCHA form." then you probably have to add a

          $messageStack->add('WHATEVER-PAGE-NAME', GOOGLE_RECAPTCHA_CHECK_ERROR); 

to the:
class.google_recaptcha.php file at the bottom for that page. My file is different since I'm not using what is available for download. I added the 2.0 reCAPTCHA myself before it was available for download by David so my implantation is slightly different. Below is how I did it so you can get an idea:

// Zencart stuff
class google_recaptcha extends base {
    function __construct() {
            $this->attach($this, array('NOTIFY_CONTACT_US_CAPTCHA_CHECK', 'NOTIFY_CREATE_ACCOUNT_CAPTCHA_CHECK', 'NOTIFY_TRACKING_CAPTCHA_CHECK'));
    }

    function update(&$class, $eventID, $paramsArray = array()) {
        global $messageStack, $error, $secret;
        $event_array = array('NOTIFY_CONTACT_US_CAPTCHA_CHECK' => 'contact', 'NOTIFY_CREATE_ACCOUNT_CAPTCHA_CHECK' => 'create_account', 'NOTIFY_TRACKING_CAPTCHA_CHECK' => 'tracking');
        // reCAPTCHA response?
        if(isset($_POST['g-recaptcha-response'])){
          $captcha=$_POST['g-recaptcha-response'];
        }
        if(!$captcha){
          $messageStack->add('contact', GOOGLE_RECAPTCHA_CHECK_ERROR);
          $messageStack->add('create_account', GOOGLE_RECAPTCHA_CHECK_ERROR);
          $messageStack->add('tracking', GOOGLE_RECAPTCHA_CHECK_ERROR);
          $error = true;
        }
    return $error;
    }
}

I tried both with no luck. When I added the mesage stack error it locked things up and the FAQ wouldn't submit, and the class file had no effect.
