How do I make a field required and shown only when a date has been passed?

[Shounak Ghosh]

I have a custom field called Due Date, which is a custom field in which a user inputs the date that they would like a Jira Issue to be resolved by. I also have a custom field called Why Was Due Date Missed, which is a multi line text entry field, which is hidden and not required by default. On the transition from the last workflow status to the resolution, I want the screen to force the user to enter something into the Why Was Due Date Missed Field before being able to transition the issue to a resolution status, if the current date is past the value of the Due Date field. What is the best/easiest way of doing this? Thanks in advance!

Hi Shounak,

You may need an add-on to fully accomplish this task, however, I would start with the knowledge base article How to display a Field based on another Field's selection and see if you can modify it for your needs:

If you would like show a Field B, ONLY if certain value from Field A is chosen, it can be achieved by performing the following steps:

1. Create a "Free Text Field (unlimited text)" custom field type in the (Administration -> Issue Fields -> Custom Fields) page

2. In this example, if a Priority - Critical (Field A) has been chosen for an issue, another field (Field B) will be displayed. Fill in the following text into the Description field (Field B):

   <script type="text/javascript">
     priority = document.getElementById('priority');
     if (priority) {
         target = document.getElementById('customfield_10000');
         // Hide the target field if priority isn't critical
         if (priority.value != 2) target.style.display='none';
    
         priority.onchange=function() {
             if (this.value == 2) {              
                        target.style.display = '';  
                        target.value="enter message here";
                     } else {
                    target.style.display='none';
             }
         }
     }
    </script>
   

    Make sure to change the customfield_ID and priority.value. To find the customfield_id, view the source of the page when viewing an issue, or check the URL when editing a custom field.

Cheers,
