I don't know if I'm doing it right but I have managed to add the CAPTCHA to my form.
I am however unable to set certain configs of which the num_chars is most important to me.
It seems like "mode" and "name" are successfully set but no other values.
This is what I have so far:
include_once XOOPS_ROOT_PATH."/Frameworks/captcha/formcaptcha.php";
$rc = new XoopsFormCaptcha();
$reg_captcha = $rc->setConfig("mode","image");
$reg_captcha = $rc->setConfig("name","verification_code");
$reg_captcha = $rc->setConfig("num_chars",6);
$reg_captcha = $rc->render();
$reg_form->addElement($reg_captcha, true);
I would rather do it by the setConfig instead of touching the captcha config.php file (from which all settings work).
