set a custom field mandatory based on field's selection

[QK]

Hi! 

I have one question.  For example I have a fieldA that has values (Val1 , Val2,Val3) 

If I  select val1 and val2 I want to change another fieldB and make it mandatory, if Val3 is chosen , nothing should happen. How can I do that?

Hi @QK,

Do you have Script Runner plugin? If yes,

• Go to Behaviours
• Add new mapping to your project and issutype
• Add new field (choose fieldA)
• Add server-side script and paste the code

def fieldA = getFieldById(getFieldChanged())
def fieldB = getFieldById("customfield_xxxxx")

String selectedOption = fieldA.getValue();

if(selectedOption.equals("Val1") || selectedOption.equals("Val2")){
    fieldB.setRequired(true)
} else {
    fieldB.setRequired(false)
}

Btw, there are different plugins on marketplace that provides this feature.

Thank you,

I tried it but it doesn't work. Maybe I am writing something incorrectly. Can you tell me what field should I write in 

getFieldById("customfield_xxxxx")

 ?

Please write your customfield id of fieldB. Ex: customfield_12345.

In order to find it;

• Go to "Issues -> Custom Fields -> %Your customfield%"
• Than click the Edit button.
• You should see the cf id in URL.

Hello @QK

You can also use

getFieldByName(<name of your custom field>)

Please see the APIs here
