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 (http://github.com/dennylin93/rcguard/tarball/0.2.0).

Also on GitHub: rcguard (http://github.com/dennylin93/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 (http://cloud.github.com/downloads/dennylin93/rcguard/rcguard-0.2.0.tar.gz).

Nice plugin, can you post some screenshots?

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

great work plugin works fine !!!

many thanks

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.

in my firefox works with this
tested with FF 3.6 and 3.5 IE6, IE7 and IE8, Opera 10, and Google Chrome tested with Windows 7 and XP and FF 3.6 under linux.

which FF version you use.

I'm using Firefox 3.6 and Opera 10 under FreeBSD.

Thank you very much for this wonderful plugin :-)

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!

Hmm, looks like there's a problem with the method I'm using to insert the reCAPTCHA code.

Can you post the plugins you're using (in the order listed in the config) as well as a copy of the HTML code from your browser?

Quote from: lumen;28560Do you have any ideas?

In this code:



You have these two HTML tags at one line:


In rcguard.php the code:
    $tmp = str_ireplace('',
      '


', $tmp);

searches for single HTML tag:


You have two ways:

• Edit plugin's files rcguard.php
  
• Edit your index.php file
  

Why this happened?
I think because you had made incorrect changes in your file:
skins/default/templates/login.html

There is another magic method to do this one.
And it has to be included in the plugin by default.

• Open file:

rcguard.php

• Find line:

$this->include_script('rcguard.js');

• Replace with:

   if($_SESSION['language']){
        if(is_readable('localization/' . $_SESSION['language'] . '.js')){
            $this->include_script('localization/' . $_SESSION['language'] . '.js');
        }else{
            $this->include_script('rcguard.js');
        }
    }else{
        $this->include_script('rcguard.js');
    }

• Open plugins localization folder and add *.js files for your languages.
  
  For example:
  
  • ru_RU.js
    
    Code Select Expand
    var RecaptchaOptions = {
  theme : 'white',
  lang : 'ru'
};

    
  • de_DE.js
    
    Code Select Expand
    var RecaptchaOptions = {
  theme : 'white',
  lang : 'de'
};
