File uploading validation not working

[noorealamdev]

<input id="attachment" name="attachment" type="file" class="form-control text-dark">

$rules = ['attachment' => [ 'required', 'string'] ];

I am not getting any error messages for the upload fields. Is there any way to make it work?

Thanks in advanced

Thank you for reporting this issue!

Currently, file upload validation is not supported in our wp-validator package, but we have plans to introduce this feature in the future. Stay tuned for updates!

Thank you!
