MAJOR IMPROVEMENTS:
1. USER VERIFICATION & SAFETY
- verify_user_ownership(): Check that extracted user matches file owner
- user_is_valid(): Validate user exists and has valid home directory
- Prevents modifications on wrong users or system accounts
2. WP-CONFIG SYNTAX VALIDATION
- validate_wp_config_syntax(): Check PHP syntax before and after changes
- Uses php -l if available for comprehensive validation
- CRITICAL: Re-validates after modifications to catch any syntax errors
- Automatic restore from backup if syntax becomes invalid
3. DUPLICATE PREVENTION
- cron_job_exists(): Check if cron job already exists before adding
- disable_wp_cron_exists(): Check if DISABLE_WP_CRON already defined
- Remove old cron jobs before adding new ones (prevents accumulation)
- Prevents duplicate entries in crontabs
4. PRE-FLIGHT CHECKS
- preflight_check(): Comprehensive validation of all installations
- Validates all WordPress sites on server before any changes
- Shows count of valid vs invalid installations
- Can be run independently (Menu Option 9)
5. DETAILED STATUS REPORTING
- show_installation_status(): Display current state of all WP sites
- Shows: User, WP-Cron status, System Cron Job existence
- Helps verify correct installation before modifications
- Can be run independently (Menu Option 10)
6. CASE 2 ENHANCEMENTS (Single Domain)
- Full validation chain before ANY modifications:
* User validation
* User ownership verification
* wp-config syntax validation (BEFORE)
* DISABLE_WP_CRON existence check
* Cron job existence check
* Re-validation (AFTER wp-config modification)
- User confirmation for non-standard cases
- Clear status messages for each check
- Duplicate prevention with automatic old job removal
7. NEW MENU OPTIONS
- Option 9: Run pre-flight checks on all installations
- Option 10: Show detailed status of all WordPress sites
- Helps users validate system before running operations
8. CRON JOB VERIFICATION
- All cron jobs are verified to go into correct user's crontab
- User extraction confirmed against file ownership
- Cannot accidentally create root crontab entries
- Prevents privilege escalation risks
SAFETY FEATURES:
- Multiple layers of validation
- Automatic backup creation
- Syntax verification before/after changes
- Automatic restoration on syntax failure
- Confirmation prompts for edge cases
- Comprehensive error messages
Ready for production deployment with high confidence!
