+If you want to ensure all form submission data is filtered out irrespective of field names for situations where there are a lot of forms that might request private information, you can do that too. The field names will still be transmitted, but the values will be filtered out.
+```php
+$raygunClient->setFilterAllFormValues(true);
+```
+
 Note that when any filters are defined, the Raygun error will no longer contain the raw HTTP data, since there's no effective way to filter it.
