Protects Joomla! core forms and 3rd party extensions by integrating spam protection services and adds an arithmetical problem, a hidden field and a time lock

Enhance your website's security with EasyCalcCheck Plus, a powerful plugin to protect your registration and contact forms from spam threats. This plugin works by incorporating a simple arithmetic task, a feature known to deter spambots effectively.

For added security, the plugin allows you to activate a hidden field and impose a time limit for form submission. The hidden input field is particularly effective against spambots, which typically fill in every available field, hidden or not, whereas regular users do not see or interact with it. The time limit further bolsters protection by restricting too-fast submissions, a common characteristic of bot activity.

When internal spam protection falls short, EasyCalcCheck Plus integrates seamlessly with external anti-spam services like Akismet, Mollom, and others.

But the utility of EasyCalcCheck Plus extends beyond spam protection. It offers backend security via a token system and guards against SQL injection threats, delivering a comprehensive security solution for your site.

EasyCalcCheck Plus has been honed and improved over several years, incorporating support for popular form components like FoxContact, Kunena Forum, FlexiContact, and DFContact. Its adaptable design allows for quick and easy extension to other components, offering a robust defence against spam messages and registrations caused by spambots.

As a testament to its effectiveness, EasyCalcCheck Plus holds a top position in the captcha category on Joomla! Extension Directory. Thanks to its continual development, optimization, and user-centric approach, it ranks among the best-rated extensions overall.

The plugin's continuous development journey includes bug fixes and the addition of support for various 3rd party extensions, such as ALFContact, JomSocial, and Virtuemart.

Choose EasyCalcCheck Plus to secure your website and enjoy a spam-free, seamless user experience.

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!

In the beginning, I recommend using the standard settings. If some spam still gets through, you should consider activating an external service like Akismet.

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, comprehensive 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 spambots 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: EasyCalcCheck Plus is a system plugin and not a plugin from the Captcha group. The option "Default Captcha" in the global configuration and the settings of the user management should be deactivated. Use EasyCalcCheck Captcha if you want to have a plugin using the Captcha group!

The response contains information on whether the transmission was successful or not. The response can then be processed further with JavaScript. Enter one rule per line; you may define any number of parameters.
+ Added Custom Call support for the newsletter module from AcyMailing. Thanks to Frank D. for requesting it!

+ Added support for Convert Forms using the Custom Call feature.

Add the custom CSS class ecc-custom-call in the "Advanced" section of this field. This class will apply some rules to improve the output of the calc check input field.
Optional: Create a template override of the input fields in ECC+ using the Template Manager and adjust the output to match the form component's output. Use the files with the suffix "Custom" to edit fields from the Custom Call.

+ Added template files for all visible input fields to allow custom adjustments easily. Each input type (calc check, question and hidden) has two variants: the default load and the custom call (file name ends with Custom).
^ Improved Custom Call to handle AJAX requests and responses in JSON-Format (instead of redirects).

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+!

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
^ Updated Custom Fields
^ Changed - Error output message not via Get parameter but via session variable

# Encrypt feature - decode all variables as soon as possible and only if they are set in the global request variables - Thank you Frank (deweso.de) for reporting it!

Version 2.5-7 - 20-Nov-2012

+ aiContactSafe - Protection of the aiContactSafe forms - Note: ECC+ can only be used without the AJAX functionality of aiContactSafe. The values of ECC+ have to be generated new and reset in the output of the form on a request, but this is not possible in the AJAX request of the component. 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!
+ FlexiContact Plus - Akismet / Mollom checks
^ Excluded all language files (except English and German) to Transifex - Looking for your language? Then check Transifex. If your language is not fully translated or not in the list at all, then register to Transifex and join the translation team. Every help is welcome!
