validator or conditional check to have minimum 2 values in custom field with multiple input

[Manu...]

Hi Team,

Could you please guide on how i can define a conditional check or validator before submission of request on having 2 values inputs at least in multiple input custom field with a comma as separator.

 i.e 

abc,cde 

If value given is only 1 than it should not allow the action to submit the request.

Are you on Jira server/Data Center our Jira Cloud?

 Also, what is the field type of the field you want to check?

Hi, David! I'd like to enjoy the ride here... I also need to do the same.

I have a multi-select user picker to set approvers. It's Jira Cloud.

I need to be sure that user chooses at least 2 approvers. Is that possible with regex validator? What would you suggest?

I don't believe it's possible with a "regex" validator. But you can easily do this with JMWE's Build-your-own Validator with this code:

!!issue.customfield_10500 && issue.customfield_10500.length >= 2

where you need to replace  customfield_10500 with the field ID of your multi-user picker custom field.
