Validator

[Jamil Rahimov]

Let suppose we have one text custom field and this customfield should be in this format:
1111 **** **** 1111 - in such format, only first 4 digits and 4 last digits must be entered

How can I do this using validator?

Hi @Jamil Rahimov ,

I'm probably still struggling with the understanding of your use case, so could you please provide a couple of examples for valid inputs?

Assuming the requirement is

• start with four numbers
• a whitespace
• four alphanumeric values (letters or numbers)
• another whitespace
• another four alphanumeric values (letters or numbers)
• another whitespace
• end with four numbers

an expression matching this would be 

 ^\d{4}\s\w{4}\s\w{4}\s\d{4}$

Cheers
Thorsten

Hey @Jamil Rahimov ,

if you're after the '*' symbols, please use

^\d{4}\s\*{4}\s\*{4}\s\d{4}$

Cheers

Hi @Jamil Rahimov

@Thorsten Letschert _Decadis AG_ has the right expression from what I can see.

You could try this with ProForma Lite (free) by requiring users to match a regex pattern.

Here's what that looks like in the form builder:

I am on the ProForma team, but thought I'd share this in case it helps get you what you need.

@Peter Preston 
These are examples which this expression should check:

Examples:
4942 **** **** 7452
2514 **** **** 5893

You'll need a scripting app, or something that provides clever validators to do this.

There are several apps that provide regular expression validators, I'd reach for one of those first (unless you have a load of other needs that bigger apps like Scriptrunner or Powerscripts might help with as well as being able to provide such a validator)

I tried Validation based on regular expression of JWT plugin but it didn't work for me.
Maybe I wrote something wrong

That app has worked for me in the past.  I'm not a regex expert, I'd have to guess that there is something wrong in that?
