Support Thread for Google reCAPTCHA plugin

[David Allen]

David,
Thanks for the awesome module! Initial installation was a super simple.
I am atttempting to add the reCaptcha to the AJAX FAQ module following the tips you gave others on adding it to the ask a question module.
Unfortuantely I have not gotten far, with the added reCaptcha code to the class file for the faq when I click submit nothing happens...
You can take a look on the product page HERE by clicking on Ask A Question, just below the part number.
Any insight on how to get this working as well as it does on the other pages would be greatly appreciated.

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

I have tried to use this module for my client and it is a good module but there are a few problems when you try to use many Google Recaptcha on one page. It can not with this module. I think author needs to update the code with this code:

https://developers.google.com/recapt...xplicit_render

[David Allen]

I could have done it that way, but because stock Zen Cart only has one form per page it wouldn't be worth it. If you want several reCaptchas on the one page, you have correctly identified how to change things to make that work

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.

[David Allen]

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:
