Validator - Booleen expression question

[steve.collins]

Hello,

I need help in creating a Booleen expression for a Field Validator to 

1. Allow the user to enter nothing

2. If the user enters a value, that value needs to be numeric characters and 6 characters in length

Thanks

Hi @steve.collins , I have tried to do this in a vanilla Jira cloud instance and it is not doable, because the premise of the out-of-the-box validator is it has to have a value and then extra checks depending on the type of validator you want.

What I can suggest is to use JMWE for Cloud and look for Scripted validator.

• #1 is easy just make sure it is empty and return false 
• #2 use regex like so [0-9]{6} 

Refer to this doc.

Thanks 

I was hoping I could add the expression something like [0-9]{6}^null

in other words the field could be 6 digits long OR not entered

What would be the correct expression for this ?

Hi @steve.collins ,

Aha!, it's definitely doable but you have to find the right regex for it.

Something similar to this.

Maybe, I'll test this later.

(^$|[0-9]{6}$)
