Author Topic: New reCAPTCHA plugin (Read 16791 times)

dennylin93 · « **on:** February 06, 2010, 08:19:05 AM »

Hi, I've written a plugin that shows a reCAPTCHA box after too many failed login attempts. The failed attempts are saved in SQL and purged after a certain amount of time.

Fixed issues:

MySQL and PostgreSQL are supported.
IPs aren't purged if user doesn't visit.
Users that fail reCAPTCHA aren't allowed to login. However, the method is crude and ugly.
Might conflict with the remember_me plugin.

The gzipped file: rcguard-0.2.0.tar.gz.

Also on GitHub: rcguard.

Comments and suggestions are welcome. This is my first plugin, so there probably are a lot of problems.

All the issues should be fixed with this version: rcguard 0.2.0.

Sure, I've attached a screenshot of the login form.

to change language in capchta
edit rcguard.js

and replace
var RecaptchaOptions = {
  theme : 'white'
};

with
var RecaptchaOptions = {
  theme : 'white',
  lang : 'de'
};

de for German

see here for more options

recaptcha dont display correct in some old Browsers IE6 IE7
to fix this edit rcguard.css and replace all with

@charset "utf-8";

#rcguard {
margin-bottom: 0px;
}

#recaptcha {
position: relative;
}

Hmm... Looks like we have a problem. The fix above doesn't work with Firefox. I'll try to find a solution that works with all browsers.

Hi dennylin93,

i have implement a little optimization to rcguard
this delete after successful login the mysql entry of this user from rcguard table.

see attachment

Thanks for the feedback.

I actually added this feature previously, but took it out later. If someone successfully hacks into an account, then the entry is deleted and he can skip the reCAPTCHA verification.

I think I'll add this as a tunable feature with on and off in the config file. I've been really busy recently, so I'll have to find some time to do this.

I have a problem: Recaptcha does simply not appear.

What I did: Created SQL tables, installed and activated the plugin, registered at recaptcha service, copied and configured config.inc.php with the pub and private keys... Hmmm.

EDIT: What's wrong? With phpmyadmin (I'm on a web hoster) I can see the MYsql rcguard table has NO entries...

EDIT2: SOLVED, I was stupid. I added the 'rcguard' entry to an outcommented plugins line (//) OMG

So, the plugin WORKS NICELY. THANKS!
