Changelog:

[v1.1] – 2025-11-24

Enhancements / Bugfixes

• Refactored indexAction() to fully support partial imports and display results reliably.
• Added importAttempted flag to always show import results, including success/failure counts.
• Added row-level validation:
  • Email format (GeneralUtility::validEmail)
  • Group title empty check
  • Group title max length based on TCA['fe_groups']['columns']['title']['config']['max']
• Row-level errors are tracked in $rowErrors for table display in backend.
• Implemented caching for:
  • Existing frontend users per PID ($existingUsersCache)
  • Frontend groups per PID ($groupsCache)
• Updated subscribeFrontendUser() to:
  • Update groups for existing users (including disabled users) without changing other fields.
  • Return 'insert' | 'update' | 'skip' for counting purposes.
  • Update cache dynamically to avoid repeated DB queries.
• Preloaded existing users with preloadExistingUsers() for performance improvement.
• Ensured passwords are generated securely and never communicated externally.
• Form-level argument validation separated from row-level errors.
• Use Doctrine\DBAL\QueryBuilder with proper restriction handling (DeletedRestriction)
• Optimized XLSX import loop for large files (1–2k rows).
• Removed unnecessary 0 group values when updating usergroups.
• Cleaned template integration to display:
  • Counts (inserted, updated, skipped)
  • Row-level error table
  • Form always below results for repeated imports.
