Hi,

thanks for your work on this plugin! I update my recaptcha.php code with your last edit and solve some issues. Now i'm trying to do something ... unusual.

I'm trying to include the recaptcha in my own plugin that simply have a form, write on db data, send data via post ajax with return json error, and send mail.
I used the method above on my html page and so add a dvi before the send button:

<?php
JPluginHelper::importPlugin('captcha');
$dispatcher = JEventDispatcher::getInstance();
$dispatcher->trigger('onInit','dynamic_recaptcha_1');
?>

from here :http://stackoverflow.com/questions/12840015/how-to-use-joomla-recaptcha-plugin-to-my-custom-module, and i can view it!

But now two things are strange:
The captcha won't load when i simply refresh the page but only when i refresh with erase browser cache,
The onInit initialise the plugin only one time per session?
But most important how can i verify capctha on submit?
I tried it, on my php send file but the page return me a ajax error.

//Verify captcha
$post = JFactory::getApplication()->input->post;

JPluginHelper::importPlugin('captcha');
$dispatcher = JEventDispatcher::getInstance();
$res = $dispatcher->trigger('onCheckAnswer',$post['recaptcha_response_field']);
if($res) === TRUE) {
$jsonObj = sprintf($status, 1, "ok");
}
else
{
$jsonObj = sprintf($status, 0, "Insert captcha");
}


Have you some suggestions, please?
Thanks
Gabriele
