This local plugin automates the process of restricting access to course modules based on the course end date. It listens to course update events and automatically applies a "prevent access after course end date" availability restriction to all modules that are tracked for course completion.

Instead of manually editing the deadline for every single activity when a course schedule changes, administrators and teachers can simply update the course end date. The plugin will instantly sync the deadline across all relevant activities.

• Automatic Synchronization: Instantly updates module availability restrictions when the course end date is modified.
• Safe Merging (Non-destructive): The plugin intelligently parses the existing availability JSON. It safely adds or updates the date restriction without overwriting or destroying existing conditions (e.g., group restrictions, grade requirements, or user profiles).
• Targeted Action: Only applies restrictions to activities that have course completion criteria enabled, leaving optional resources untouched.
• Cleanup: If the completion tracking is removed from a module, the plugin automatically removes the injected date restriction while keeping any other conditions intact.

1. Download the plugin and extract the .zip file.
2. Rename the extracted folder to enddateaccess (if it isn't already).
3. Upload or move the enddateaccess folder into the local/ directory of your Moodle installation.
4. Log in as an administrator and go to Site administration > Notifications (or run the upgrade script via CLI) to complete the installation process.

The plugin works silently in the background. To trigger it:

1. Ensure your course has an End date set in the course settings.
2. Add an activity (like a Quiz or Assignment) and configure its Activity completion settings to require a specific condition (e.g., "Student must view this activity to complete it" or "Student must receive a grade").
3. Save the activity. The plugin will automatically append the date restriction based on the course end date.

• Moodle 3.5 or later (Requires version 2018051700).
