ECR - Easy Content Restriction

Version 4.2.0.0-PRO - 2023-09-22

• + Improved Installation Script. Updated the installation script to check for the highest compatible version of Joomla automatically! This feature aims to prevent issues that may arise from using incompatible core versions, thereby ensuring a smoother installation process.

Version 4.1.4.0-PRO - 2023-04-26

• + Added Password expiration time option for Password Protection Rules. The password expiration time option is a helpful feature for keeping your content secure. However, if you prefer not to use this feature, leave the field blank, and the password will not expire. Thanks to Svetoslav Slavkov for requesting this feature!

Version 4.1.3.0-PRO - 2023-03-15

• + Added Brute Force Protection - IP Address Blocking feature. Thanks to Svetoslav Slavkov for requesting this feature!
• + Added Activate IP blocking for password inputs option. With this option, the plugin blocks IP addresses from accessing the protected content if they exceed the allowed number of submission attempts. All password requests from restricted IP addresses are blocked directly by the plugin. After the specified block time, the IP addresses are removed from the lock list and can enter the password as usual again.
• + Added Number of allowed submission attempts option. The maximum number of submission attempts until the IP lock is triggered and the form cannot be bypassed anymore, even with the correct password.
• + Added Blocking time in seconds option. Blocks the IP address for the selected time span. Default value: 3600 seconds (corresponds to 1 hour).

Version 4.1.2.0-PRO - 2023-03-09

• + Added Disable replacement in editor option. With this option, you may disable replacing the syntax in editor view in the front end for signed-in users. Use this option if you are working on articles in the front end and the syntax is being removed due to the wrong context in the edit view. Note: This option is only available for signed-in users from the allowed group list and if the safe mode is disabled. Thanks to Freddy B. for requesting this feature!
• ^ Optimised the syntax removal functionality from version 4.1.1.0-PRO. If the safe mode is enabled, the removal is always triggered. Additionally, added user status and editor checks.

Version 4.1.1.0-PRO - 2023-01-20

• + Improved the syntax removal if the content was not loaded in the content context, e.g. feed or search. Thanks to Haven for reporting it!

Version 4.1.0.0-PRO - 2023-01-06

• Increased technical requirements for Joomla! 4: Increasing Technical Requirements - Core & PHP for Joomla! 4 Pro Extensions
• + Added Password Protection Rules feature. This option protects the replacement text with a password by pre-defined rules with a unique hash. The replacement text is loaded from an assigned, unpublished article. A hash is generated to map the password rule in the article, which protects sensitive data even if the article is loaded directly from the database (e.g. via a third-party extension). The password cannot be derived from the hash. You may use the following syntax to load the password form at the desired position in the article: [ecr]HASH[/ecr]
• ^ Code optimisations

Version 4.0.7.0-PRO - 2022-11-16

• [ecr|confirmation]<iframe ....></iframe>[/ecr]
• You may overwrite the default confirmation headline and text by adding a third and fourth parameter to the syntax (see example in the Password Mode) or by language overrides for the language constants PLG_SYSTEM_EASYCONTENTRESTRICTION_CONFIRMATION_HEADLINE and PLG_SYSTEM_EASYCONTENTRESTRICTION_CONFIRMATION_TEXT.
• Thanks to Ufuk A. for suggestion this feature!

• ^ Optimized the user group determination - removed the loading of inherited groups
• ^ Updated version check, donation code and krtitle fields

Version 2.5-1 DEV-2013-06-07

• + This is the first public test release. The language files are incomplete, also the description is very minimal but the functionality is fully implemented. Check the short description to see how to use the plugin. In fact, it is very simple: enter the described syntax in your articles to hide text from unauthorized groups. The plugin uses the unusual syntax with square brackets, not curly brackets, due to security reasons. Extensions, like the search component, remove plugin calls before they call the trigger. If the syntax is removed, the plugin can not be executed and the hidden text could become visible. Square brackets are not recognized as the typical plugin syntax and the plugin also works in these cases. The replacement text can be entered in the settings or via the override feature in the syntax. You may use HTML tags (e.g. to set a link to the registration page etc.). There is also a safe mode which completely hides the text when the article is not called from the content component (e.g. search component or modules). Use the options of the plugin to set global settings and the override functionality to set local settings. Additionally, you may allow access to the hidden text passages to certain users by adding their user IDs into the settings. Enter the IDs separated by commas.
