📝 Usage Examples

For Administrators

Viewing Errors:

1. Go to WordPress Admin → FormsCRM
2. Click "Error Log" tab
3. View list of all errors

Filtering Errors:

1. Select status from dropdown (Failed/Success)
2. Select CRM type from dropdown
3. Click "Filter" button

Resending Failed Entry:

1. Find the failed entry in the list
2. Click "Resend" button
3. Wait for confirmation message
4. Status updates to "Success" if resend works

For Developers

Accessing Error Log Programmatically:

global $formscrm_error_log;

// Get failed logs for Holded
$logs = $formscrm_error_log->get_logs( array(
    'status'   => 'failed',
    'crm_type' => 'holded',
    'per_page' => 20,
    'page'     => 1,
) );

// Get total count
$total = $formscrm_error_log->get_total_count( array(
    'status' => 'failed',
) );

// Delete a log
$formscrm_error_log->delete_log( $log_id );

🚀 Performance Considerations

  1. Database Queries:

    • Pagination limits results to 20 per page
    • Indexes on frequently queried columns
    • Prepared statements for query optimization

  2. AJAX Operations:

    • Non-blocking operations
    • User feedback during processing
    • Error handling for failed requests

  3. CSS/JavaScript:

    • Minimal additional assets
    • Loaded only on Error Log page
    • No jQuery dependencies beyond what WordPress provides

💡 Future Enhancement Ideas

While not implemented in this version, consider these for future releases:

  1. Export Functionality: Export error logs to CSV
  2. Automatic Retry: Scheduled retry for failed entries
  3. Advanced Search: Search by error message or form name
  4. Error Analytics: Dashboard with error statistics and graphs
  5. Bulk Operations: Select multiple entries for bulk resend
  6. Email Digests: Daily/weekly error summaries
  7. API Integration: REST API endpoints for external monitoring
  8. Error Grouping: Group similar errors together
