How to make a custom field required when check box is checked?

Irshad Sheik

I have a check box that if checked it needs to validate that a separate custom field needs to contain data or the ticket cannot be closed. however if the check box is not checked the the custom field can remain empty.

Hi Irshad
I'm afraid it is not possible with out-of-the-box Jira validators.
You should use something like Power Scripts For Jira to create a custom validator with if-else conditions.
Here is an example of script that could be helpful

Hello @Irshad Sheik

It's not possible out of the box, I have implemented something similar using the Behvaiour module of the Script runner paid plugin.

Morning

i tried the following and am getting an error:

string errorMsg = "Please enter Billing Instruction Number";
if (customfield_13500 == 1 && !hasInput("customfield_13600")) {
return false,"customfield_13600", errorMsg;
}

the comma after false is producing an error saying expecting } but got ,

I think there is some error in how you specifying custom fields and its value.
On my test instance it throws a different error and if i change fields to those i got on my instance and hit Check it says "Looks good"

Try to use this

string errorMsg = "Please enter Billing Instruction Number";
if ("customfield_13500" == 1 && !hasInput("customfield_13600")) {
return false, "customfield_13600", errorMsg;
}

Also you should open any issue that contains those fields with JSON representation and check if field names and value you specifying are correct.
