Description

Protects Joomla! forms and 3rd party extensions by integrating anti-spam services and adds additionally a arithmetic problem, a hidden field and a time-out!

Plugin: EasyCalcCheck PLUS - ECC+
Function: Protection against spam messages and spam registrations
Joomla versions: 2.5
Included Languages: English and German - all language files at Transifex
Supported 3rd Party Extensions in the Joomla! 2.5 version: AlfContact, Community Builder, DFContact, Easybook Reloaded, Fox Contact, Flexi Contact, Flexi Contact Plus, JomSocial, Kunena Forum, Phoca Guestbook and Virtuemart
Integrated external antispam services: Google ReCaptcha, Akismet, Honeypot Project, StopForumSpam, Mollom, Bot-Trap, Botscout

This plugin protects you registration and contact form from spam by insertion of an arithmetic task. In addition you may activate a hidden field and a time limit. Only spam-bots fill in this field, as they tend to fill in every field there is, hidden or not. Regular users do not see the field and will not fill it, avoiding the trap. The time limit prevents that the form is submitted to fast. Bots usually fill in all the values at one time and try to send the form within seconds. A human being is not able to send a form in such a short time frame.

If the internal spam protection is insufficient, external anti-spam services (such as Askiment, Mollom, etc.) might be used.

ECC+ offers not only the spam-protection but as well other feautures like: Backend security through a token and SQL injection protection.

The plugin has been developed and optimized for some years now (see the feauters-tab). Spam in Joomla! forms doesn't get a chance with EasyCalcCheck Plus!

With the release of Joomla! stable version 1.7, I have published ECC+ 1.7.-1. The anti-spam plugin was almost completely rewritten in version 1.7.-2 for Joomla! 1.7. This delivers the base structure for the continuation and further development of the plugin. Many improvements were made which occasionally caused problems in the past. In addition to the large code optimization we added support for even more popular form components like: FoxContact, Kunena Forum, FlexiContact and DFContact. Due to the new design, the plugin can quickly and easily be extended to other components. With ECC+ you should never again face the problem of spam messages or spam registrations caused by spambots. EasyCalcCheck Plus claims the first place at Joomla! Extension Directory in the captcha category and has continued to be even more successful in the recent past. I would like to thank all who support my extension with a review!

Some bug fixing was done in Version 1.7-3 and the extension ALFContact was added to the supported 3rd party extensions.

Simultaneously with the release of version 2.5 of the Core on January 24th, version 2.5-1 of the plugin was published. In version 2.5-2 the extensions JomSocial and Virtuemart were included in the list of supported 3rd party extensions.

EasyCalcCheck Plus has been continuously developed, optimized and is meanwhile available in version 2.5-7. It has a rating of 4.97 of possible 5 points in the official Joomla! Extensions Directory and is now among the best rated extensions ever. Thank you to all users!

Installation

Install the plugin by accessing the administration menu of the back-end under Extensions. Then access Extensions – Plugins – System – EasyCalcCheck PLUS and customize it to your needs. Don't forget to activate it!

At the beginning I do recommend the standard settings. I still some spam gets through, you might activate external services like Askimet.

Enjoy! ;-) Spam is finally a thing of the past!

Spambots shouldn't be stopped only by ECC+ on the client side. The majority of spambots is easily identified with the help of blacklists and prevents proactive the loading of your website. Since version 1.5-7 bots can be identified and blocked by comparing the actual blacklist from Honeypot Project or StopForumSpam.

In addition, large anti-spam services like Akismet, Mollom, reCaptcha and Botscout have been implemented to recognize and filter spam even better!

Tip: This website and all my demo sites did not receive any entries or registrations through spam bots with the following configuration: arithmetic problem, hidden field, time lock and Akismet. If this configuration is not enough, then another spam service can be activated additionally.

Note from Joomla! version 2.5: EasyCalcCheck Plus is a system plugin and not a captcha plugin. The option "Default Captcha" in the global configuration and in the settings of the user management should be deactivated!

Changelog

+ = Added - ! = Removed - ^ = Changed - # = Fixed

Joomla! 3.x

Version 3-1 - 2013-11-17

  • + First release for Joomla! 3 - based on 2.5-8 with important modifications and optimizations for Joomla! 3.x
  • + This release is tested only with Joomla! 3.2 and core components - do not use it in a lower Joomla! version. Do not report any problems with other Joomla! versions. Only the mentioned version (and higher) are supported officially by ECC+!

Joomla! 2.5

Version 2.5-8 - 2013-11-15

  • + New feature: Custom Call - with this feature you may execute the plugin in all forms with a special syntax. ECC+ can protect all forms of your Joomla! website now. It is not restricted on components but can also be used in modules! The syntax to load the plugin is {easycalccheckplus}. This syntax has to be added in the template file of the form. The best solution is to use a template override. This option is in experimental phase and only for advanced users who know how to create a template override to add the needed syntax! ECC+ can only be executed once per page, so you have to exclude protected modules on pages where the plugin has to be loaded in a component.
  • + Improvement: Encrypt functionality - now not only 3rd party components can be protected with encryption but also all other form fields where ECC+ is loaded. Some extensions need the names of the fields to add JavaScript functionality to the forms, these fields can be excluded from being encrypted with the help of a whitelist in the definition for the certain component. Not all components were tested, so please test this function and report problems that may occur!
  • ^ Support for Virtuemart - updated the support for Virtuemart to the latest version of the component - 2.0.24a

Open the form in aiContactSafe and deactivate the option Use AJAX to submit the form if you want to use ECC+ in your aiContactSafe form!
