# Can't save empty fields

 * I’m using validated fields to save a few values, but while they validate just
   fine if they have the correct data inserted, they essentially became “required”
   fields, and return validation errors when empty.
 * Maybe the issue is my regex? These are the regular expressions I’m using:
 * `^(\([0-9]{2}\))([0-9]{4,5})([0-9]{4})$`
 * `^[A-Za-z0-9_]{1,15}$`
 * The first one is so I can validate phone numbers from my country: (99)99999999
   or (99)99999999.
 * The second one is so I can validate Twitter usernames without the @.
 * Thanks in advance.

 * Hi [@runo](https://wordpress.org/support/users/runo/),
 * If the fields are not required then the validation shouldn’t be running against
   them. Is it possible for you to test with the new beta version? I believe this
   is corrected there as I am not able to reproduce it.
 * Thanks!

 * [@runo](https://wordpress.org/support/users/runo/) thought about this a bit more
   and I think I misunderstood – basically you want to make a field not required,
   but if something is entered then you want to have it validated, otherwise let
   it be empty?
 * If so you need to make your regular expression optional by putting it in a matching
   group and adding `?`:
 * `^((\([0-9]{2}\))([0-9]{4,5})([0-9]{4}))?$`
