• Info files: Language name standardization (english→en, german→de, french→fr, etc.)
• Admin modules: Code improvements and consistency fixes
• Core system: Security and user management enhancements
• Config: Log file updates

Fixed configuration persistence issues in the changelog module where GitHub repository and token values were not being saved correctly. Changes in admin/modules/changelog.php:

• Fixed global variable: $admin_file → $aroute (consistency)
• Fixed getVar() type for GitHub fields: 'var' → 'text'
• The 'var' type uses isVar() which only allows a-zA-Z0-9_-
• Repository names like 'SLAED-CMS-6.3-Pro' contain dots, which were rejected
• GitHub tokens contain underscores and were being filtered incorrectly
• Type 'text' uses save_text() which preserves special characters

Issue details:

• getVar() with type 'var' calls isVar() function
• isVar() pattern: /[^a-zA-Z0-9_\-]/ rejects dots and many characters
• 'SLAED-CMS-6.3-Pro' was converted to '0' due to dot rejection
• GitHub tokens 'ghp_...' were also filtered incorrectly

Solution:

• Use type 'text' for github_owner, github_repo, and github_token
• save_text() preserves necessary characters while still sanitizing input
• Configuration now saves correctly with full repository names and tokens

This fix enables proper GitHub API integration configuration.

Major refactoring of admin modules with code modernization, security improvements, and new GitHub API integration for changelog functionality.

New Features

GitHub Integration (changelog.php)

Added commits() function to fetch commit history from GitHub API:

• Supports filtering by author, date range, search term
• Complete error handling with detailed HTTP status codes
• Bearer token authentication support
• Configurable commit limit (default: 50)
• Returns structured commit data: hash, author, date, message, files

Configuration added to config/changelog.php:

• github_owner: SLAED-CMS
• github_repo: SLAED-CMS-6.3-Pro
• github_token: API access token
• source: 'github' (local/github toggle)

New Monitor Module

Added admin/modules/monitor.php (~30KB):

• System monitoring and analytics dashboard
• Real-time performance metrics
• Resource usage tracking

Module Modernization

Function Naming Standardization

Unified navigation functions across all modules to generic navi():

• msgNavi() → navi() in messages.php
• privatNavi() → navi() in privat.php
• (consistently applied to all modules)

Security Improvements

SQL Injection Protection: Updated raw SQL queries to use prepared statements with named placeholders:

// BEFORE:
$db->sql_query("UPDATE ".$prefix."_message SET active = '0', expire = '0' WHERE mid = '".$mid."'");
// AFTER:
$db->sql_query('UPDATE '.$prefix.'_message SET active = :active, expire = :expire WHERE mid = :mid',
    ['active' => 0, 'expire' => 0, 'mid' => $mid]);

// BEFORE:
include('config/config_privat.php');
$permtest = end_chmod('config/config_privat.php', 666);
if ($permtest) $cont .= tpl_warn('warn', $permtest, '', '', 'warn');
// AFTER:
$cont .= checkConfigFile('config_privat.php');

Code Style Standardization

Tabs → Spaces (PSR-12): Converted all indentation from tabs to 4 spaces in:

• messages.php
• privat.php
• groups.php
• categories.php
• favorites.php
• fields.php

Double Quotes → Single Quotes:

// BEFORE:
if (!defined("ADMIN_FILE")) die("Illegal file access");
// AFTER:
if (!defined('ADMIN_FILE')) die('Illegal file access');

• tpl_eval() → setTemplateBasic()
• tpl_warn() → setTemplateWarning()

Global Variables:

• $admin_file → $aroute (consistent routing variable)

Function Signature Improvements

Type Hints and Return Types:

// BEFORE:
function privat() {
// AFTER:
function privat(): void {

// BEFORE:
function privatConf() {
// AFTER:
function conf(): void {

Major refactoring to standardize language file naming across the system, replacing verbose language names with ISO 639-1 two-letter codes. Language file renaming:

• lang-english.php → en.php
• lang-french.php → fr.php
• lang-german.php → de.php
• lang-polish.php → pl.php
• lang-russian.php → ru.php
• lang-ukrainian.php → uk.php

Applied to directories:

• admin/language/
• language/
• setup/language/

Language flag images renamed:

• setup/templates/images/english.png → en.png
• setup/templates/images/french.png → fr.png
• setup/templates/images/german.png → de.png
• setup/templates/images/polish.png → pl.png
• setup/templates/images/russian.png → ru.png
• setup/templates/images/ukrainian.png → uk.png

Admin structure changes:

• admin/admin.php → admin/index.php
• admin/modules/configure.php → admin/modules/config.php
• Removed legacy admin/links/ directory

Updated all admin modules to reflect language code changes and modernization patterns established in refactoring-rules.md. Core system files updated for compatibility with new language structure. This standardization improves internationalization consistency, follows ISO standards, and simplifies language file management throughout SLAED CMS.

• Navigation: op=new → op=add, op=file → op=fileadd
• Switch: case 'new' → case 'add', case 'file' → case 'fileadd'
• Switch: case 'add' → case 'addsave' (save operation)
• Formular: op=add → op=addsave (save action)
• Alle Operationen entsprechen jetzt exakt den Funktionsnamen
