Validate text field with required_if for date value

You can apply the dates on the date itself, and not on the backupName as I guess the date for the backup cannot be an old value neither, right?

So just:

'date_from' => 'nullable|date|after_or_equal:today'
'backups.*.backupName' => 'nullable|required_with:date_from|

No. date_from can be old date, but i want backupName is required only if date_from is today or greater.

I think i need to wite a custom validation.

For now i have put the valodation with condition as:

if($date_from > new DateTime()){ do validation }
