How to use regex to set validation for a number input on a form field

Summary

The minimum and maximum field attributes designed in the number type field in Jira forms take into account the number of digits and not the numerical values. If you add the minimum as 3 then the values accepted are 111, 121, 133 etc.

This article explains how you create a field to input a number within a specific range or a specific format using regex validation.

Solution

You can use a short text or long text field to input the number value. Furthermore, use regex to limit the range or if you like the format in a specific pattern. Additionally, you can add an error message to be displayed for wrong values added.

So for 1-8 numbers try ^[0-9]{1,8}$ and you can even specify an error message.
