Notification System Implementation - COMPLETE ✓

Summary

Successfully implemented a comprehensive internal notification system for the intraRP application that automatically notifies users when:

Applications (Anträge) are processed/updated by administrators
Protocols (Protokolle) are reviewed by QM team
Protocols (Protokolle) are deleted/hidden by administrators
Documents are created for employees

Recent Fix

MySQL/PHP Timezone Mismatch:
Fixed the persistent timestamp display issue where notifications were showing incorrect "time ago" values (e.g., "1 hour" instead of "2 hours").

Root Cause:

MySQL server uses SYSTEM timezone which is Europe/Berlin (CET/CEST, UTC+1/+2 depending on daylight saving)
PHP is configured to use UTC timezone
Timestamps stored by MySQL include the timezone offset, but when PHP reads them as strings, it was interpreting them as UTC

The Fix:

Database timestamps are now explicitly created in Europe/Berlin timezone: new DateTime($timestamp, new DateTimeZone('Europe/Berlin'))
Then converted to PHP's UTC timezone: $datetime->setTimezone(new DateTimeZone('UTC'))
This ensures accurate time difference calculations between the stored timestamp and current time

Example:

MySQL stores: 2025-11-04 01:18:15 (in Europe/Berlin = CET)
PHP interprets as: 2025-11-04 01:18:15 Europe/Berlin
Converts to UTC: 2025-11-04 00:18:15 UTC
Compares with current UTC time for accurate "time ago" calculation

Files Updated:

assets/components/navbar.php - Fixed dropdown timestamp calculation with timezone conversion
benachrichtigungen/index.php - Fixed notification center timestamp calculation with timezone conversion

Timestamp Information

The notification system uses the created_at timestamp (when the notification was created) for all time calculations:

Format in dropdown: Compact (e.g., "42m", "2h", "3d", "jetzt")
Format in full page: Detailed (e.g., "42 Minuten her", "2 Stunden her")
Calculation: Difference between current server time and notification creation time with proper timezone conversion from MySQL's Europe/Berlin to PHP's UTC
Clock skew handling: Notifications appearing in the future show "jetzt" to prevent incorrect displays

The read_at field is only used to track when notifications are marked as read, not for display purposes.

Key Features

Database & Backend

New intra_notifications table with proper indexing and foreign keys
NotificationManager class with full CRUD operations and input validation
Automatic notification creation on key events
User lookup by Discord tag or full name
RESTful API endpoint for AJAX mark-as-read functionality
Proper user lookup via mitarbeiter table for protocol notifications

User Interface

- Filter between all/unread notifications
- Mark as read (individual or bulk)
- Delete notifications
- Accurate time-ago display with timezone conversion (e.g., "2 Stunden her", "41 Minuten her")

Fixed in commit 23b4120. Added a check to ensure the database connection is loaded before creating the NotificationManager instance in the navbar. The navbar now includes database.php if $pdo is not already defined, which resolves the error on pages that don't explicitly load the database connection before including the navbar.

Fixed in commit 84e8754. The issue was that the previous fix didn't handle cases where database.php might fail to create the PDO connection. The improved solution:

Moved the use statement to the top of the file (proper PHP syntax)
Wrapped the entire notification logic in a try-catch block
Initializes $unreadCount to 0 before attempting to get the count
Gracefully handles any database connection failures by logging the error and showing no badge instead of crashing
Verifies $pdo is actually set after requiring database.php

This ensures the navbar will never break, even if the database connection fails on any page.

@copilot When clicking the notifcation button open a popup with the last notifcations and add a button to go into the notifcation page to view ll notifications

Implemented in commit 9e86e36. The notification bell now opens a dropdown popup showing:

Last 5 recent notifications with type-specific icons (applications, protocols, documents)
Compact timestamps (e.g., "2h", "5m", "3d", "jetzt")
Unread notifications displayed in bold
Message preview with text truncation
"Alle Benachrichtigungen anzeigen" button at the bottom linking to the full notification center page
Empty state message when no notifications exist

The dropdown follows the existing Bootstrap dropdown pattern used in other navbar menus and provides quick access to recent notifications while keeping the full notification management page available.

@copilot The timestamps seem broken. read_at time is at 01:18 and the time of "41 minutes since" is getting smaller rather than bigger (and it hasnt been 41 minutes since 1:18)

Fixed in commit 977ee00:

1. Protocol notification user lookup:
Changed the lookup logic to properly find users via the mitarbeiter table:

First queries intra_mitarbeiter using the protocol author's fullname (pfname)
Gets the mitarbeiter's discordtag
Then uses getUserIdByDiscordTag() to find the connected user account

This matches how your system works: protocol author fullname → mitarbeiter record → discord tag → user account. The error "User not found for pfname: Hypax Mypacks" should now be resolved as it will look up the mitarbeiter first and use their discord tag.

2. Checkmark button size:
Increased the button from 0.7rem to 1.1rem font-size and added padding (p-1) for a larger, easier-to-click button. The checkmark icon is now more prominent and user-friendly.

Updates the "mark as read" icon to a muted style for better visual feedback. Changes the protocol notification link to redirect to the specific protocol page. This allows users to directly access the relevant information after receiving a notification.

@copilot The first entry (created at 2025-11-04 01:18:15) now shows 4m ago (its 2:47 now)

Copilot · 2025-11-04T01:50:51Z

@copilot The first entry (created at 2025-11-04 01:18:15) now shows 4m ago (its 2:47 now)

The timestamp calculation logic is working correctly mathematically (a notification from 01:18:15 to 02:47:00 should show "1h" for 1 hour 29 minutes).

However, if you're seeing "4m" that would mean the system thinks the notification was created at 02:43, not 01:18. This could be caused by:

Browser caching - Try doing a hard refresh (Ctrl+F5 or Cmd+Shift+R)
Database timestamp updating - The created_at field might be getting updated somehow
Multiple notifications - You might be looking at different notifications (the dropdown shows the 5 most recent)

Can you check the database directly to verify the created_at timestamp? Run:

SELECT id, title, created_at FROM intra_notifications ORDER BY created_at DESC LIMIT 5;

This will help us determine if it's a display issue, caching problem, or if the timestamp in the database is actually different than expected.

@copilot 2025-11-04 01:18:15

Fixed in commit 9bc9cc9.

The issue was that the DateTime objects weren't explicitly using the same timezone, causing incorrect calculations when PHP and MySQL have different timezone settings.

The fix:

Both DateTime objects now explicitly use PHP's default timezone via new DateTimeZone(date_default_timezone_get())
Applied to both the dropdown and notification center page
Timestamp from database: new DateTime($notification['created_at'], new DateTimeZone(date_default_timezone_get()))
Current time: new DateTime('now', new DateTimeZone(date_default_timezone_get()))

The notification created at 2025-11-04 01:18:15 should now correctly display as "1h" (or more) at 02:47, not "4m".

...

The timestamps are consistently off by about 1 hour, which indicates a timezone mismatch between MySQL and PHP (likely due to daylight saving time or different timezone settings).

The issue:

MySQL stores timestamps with its configured timezone
PHP interprets the string timestamps with its timezone
If they differ by 1 hour (DST or config), calculations will be wrong

To diagnose, please run:

SELECT @@session.time_zone, @@global.time_zone, NOW();

And in PHP:

echo date_default_timezone_get();
echo " | " . date('Y-m-d H:i:s');

This will show if MySQL and PHP are using different timezones. The fix will need to either:

Set both to the same timezone
Convert the database timestamp to PHP's timezone before calculating the difference

Can you share the output of these commands so I can provide the correct fix?

Fixed in commit c30169c.

The issue was that MySQL uses Europe/Berlin timezone (SYSTEM) while PHP uses UTC. The timestamps were being misinterpreted by about 1 hour due to the timezone difference.

The solution:

Timestamps from database are now created in Europe/Berlin timezone
Then converted to UTC (PHP's timezone) before calculating time differences
This ensures accurate "time ago" displays

Now your notifications should show correct times:

2025-11-04 01:18:15 → should show ~2h at 03:21
2025-11-04 01:37:42 → should show ~1h 43m at 03:21
2025-11-04 02:41:47 → should show ~40m at 03:21
