Hi Gokk,

I moved this topic into Feature Request forum and still waiting to hear feedback from other users to see if they have the same interest in this feature. If this feature is needed by other users as well we will consider it for our next release.

How far are you going with captcha implementation in your site? Do you need any technical assist from us?

Regards,

Okay,
I've been playing around with it, but no luck so far, using joomla recaptcha plugin, here is what I did:
- Created public and private key on: www.google.com/recaptcha (used localhost and yeah, key works under 127.0.0.1)
- Enabled and entered keys in Joomla Captcha - ReCaptcha plugin.
Found this:

Goes to file where you want to show recaptcha:
JPluginHelper::importPlugin('captcha');
$dispatcher = JDispatcher::getInstance();
$dispatcher->trigger('onInit','dynamic_recaptcha_1');

//html code inside form tag
<div id="dynamic_recaptcha_1"></div>

This goes to file that is validating/processing the form:
$post = JRequest::get('post');      
JPluginHelper::importPlugin('captcha');
$dispatcher = JDispatcher::getInstance();
$res = $dispatcher->trigger('onCheckAnswer',$post['recaptcha_response_field']);
if(!$res[0]){
    die('Invalid Captcha');
}
NOTE! found this for Joomla 3x
$post = JFactory::getApplication()->input->post;
$dispatcher = JEventDispatcher::getInstance();

Now I need you to tell me please where exactly (what file and what line) do I put the codes in???

Hi,

Since you want to put the Captcha form into step 2 (Guest info), you need to put your Captcha checking into this file:

/components/com_solidres/controllers/reservation.json.php
public function processGuestInfo($data)
{
// Put your check here
}

This is where the guest info is processed.

Okay, I did that, what next?

Meaning, I inserted the code:
/components/com_solidres/controllers/reservation.json.php
$post = JRequest::get('post');      
JPluginHelper::importPlugin('captcha');
$dispatcher = JDispatcher::getInstance();
$res = $dispatcher->trigger('onCheckAnswer',$post['recaptcha_response_field']);
if(!$res[0]){
    die('Invalid Captcha');
}

I guess this goes to: /components/com_solidres/controllers/reservation.php
...all fields are here, I've added <div> under the fieldset...
<fieldset>
<p class="help-block">'. JText::_("SR_RESERVATION_NOTE").'</p>					
</fieldset>
<div id="dynamic_recaptcha_1"></div>
</div>

What about code for showing the captcha, what do I use and where?

Hi,

If you want to use Joomla Recaptcha plugin, please make sure that you understand how it is implemented in Joomla Core components like com_users.
