This is my first WordPress plugin that i made it for personal use and to learn how to build plugins.
This plugin replaces the submit button on the post comment section with a set of buttons from images.
A small message provides the user a hint on what button to use to submit the comment.
Demo | Github Download | WP Plugin Page
Install:
Copy files in /wp-content/plugins/cutecaptcha folder
Enable the plugin from WP Admin > Plugins
Requirements:
PHP mcrypt should be available on the server, i will add more encryption methods if required.
Session support is optional, supports caching of post pages without session but with lower security.
Tested only on WP3.3
Customize:
All the information and parameters to configure are in cutecaptcha.php
The images and messages can be customized and should be quite fun to adapt it with the
subject of each website, especially expecting that anybody that wants to post a comment
should have a good idea about that subject.
Security
The variety in images and messages will make it difficult for automated bots to break it.
The plugin is inteded for regular blogs that will never attract dedicated spammers.
At this moment the association between messages and photos can be analyzed, but it is possible to add
another layer of protection if required. I strongly suggest that each site uses personalized images and
messages related to their content.
TODO:
Alternative encryption functions for servers without php mcrypt.
Extra layer of security on images: Raw data inserted in file, modified with
variable watermarks for each session.
Display a specific number of buttons from a gallery of buttons.
IP Block: block ip’s after a number of failed submits for a number of days.
