Question [Merged topic] The great CAPTCHA problem discussion

Hmmm, well not being any sort of programmer I am a little reluctant to solve my problem with hacks.

If I understand this correctly it is simply the case that there is no facility in Kunena 1.6 to provide a captcha for anonymous postings. That seems the very place where you absolutely need a captcha. :dry: The other option would obviously be to not allow anonymous postings but, unfortunately, the people I am doing this web-site for really want to anonymous postings be allowed. They think that including a captcha and requiring the poster's email address should provide sufficient security for their needs. (personally I think they're misguided)

I was misled by the field in 'Forum Configuration|Security' that says Enable captcha system with third party plugin

Ah well, perhaps if I wait patiently it might appear 'as if by magic'.

Apart from this little iss ue I think K1.6 seems a really nice piece of work.

Is that so?

CAPTCHA is intended to be used with guest posters. I wasn't aware that we were discussing CAPTCHA for logged-in, registered uses (even those who want to remain anonymous).

Well I can't get it to work, and I can't find any posts suggesting anyone else has either.
Anyone??

The ability to use CAPTCHA has only been implemented to work for guests; in other words, if you allow public posting and you do not require users to register and login. Anonymous users is a different matter.

This didnt result in a working captcha picture for unregistered users, still the message:
The CAPTCHA plug-in is not enabled or not properly configured.

This is probably correct. I only tested this for the use case where guests are not allowed to post.

Hello everybody. Today i have faced a problem: bots have messed up my forum and i realised that i have no capture system to avoid this while guest posting is available on forum.

I'm running Joomla 1.6.3 and Kunena 1.6.3 and the plugin recommended here
docs.kunena.org/index.php?title=How_to_p...unena_1.6&setlang=ru
is ok for Joomla 1.5.x with Kunena, it doesnt work properly for J1.6.x

Since i've not found any ready solution for J1.6.x + Kunena1.6.x i've made a simple modification of joomla captcha plugin to make it work with J1.6. until the official update will be published or another solution will appear.

if u have already installed the described joomla captcha plugin, the fastest way of making captcha work is:

1) file /plugins/system/captcha/captcha.php:

string 169

JPlugin::loadLanguage( 'plg_system_captcha', JPATH_ADMINISTRATOR );
change to
$this->loadLanguage();


string 184

$enabledcaptchas = $captchaparameters->def( 'enabledcaptchas', '' );
change to
$enabledcaptchas = $captchaparameters->def( 'enabledcaptchas', 'kunena.post' );


string 430
$captcha_URI = JURI::root() . 'plugins/system/captcha/';
change to
$captcha_URI = JURI::root() . 'plugins/system/captcha/captcha/';


2) in plugin language files i.e. /administrator/language/en-GB/en-GB.plg_system_captcha.ini

replace all "#" symbols to ";" symbols

put all values into quotes. Example:

CAPTCHACODE_FORM_TITLE=Captcha code
change to
CAPTCHACODE_FORM_TITLE="Captcha code"


3) change the /plugins/system/captcha/captcha.xml file to the attached one.


Also dont forget to turn on captcha into kunena settings (security tab).

Please note, this is just a homemade temporary solution, before the respectable authors of plugin will release the official update or another captcha solution for this configuration will be released.

Please back up files (captcha.php, captcha.xml and language files) before changing them cos i had tested this only on my own site and will not have enough time to help u if any issue occure.

Regards.

here is the modified xml file for being able to edit
