checkCaptcha()protected final function checkCaptcha()
This function checks a POST submission to see if a CAPTCHA is correct.
To use it you must have previously included a CAPTCHA on a form using the $this->captcha() initialization function.
Can be used in your plugin's init() method, from Zenario 7.0.0 onwards.
if ($this->checkCaptcha())
//Do something...
} else {
//Show an error message...
}
