Hi,

I am looking to check change turn required if another field has values:

Similar to visible I thought that something could be done

This same approach works for visible: 

but not for require:

required attribute only seem to allow true/false or SESSION[...]. 

I wonder if there is any way I can make a field required if depending on a third field? (e.g. in my case FORM.isOnGoing)

Thank you.

hi,

how about a custom validator?

Hi,

I used to do this with a javascript function that listen to change in the third field and then set the field to required/not required. It works with GMSC 2016. You might want to try if it still works with GMSC2018.

IG.getFieldById('your_third_field').value.subscribe(function(newValue){
	
	if(newValue==1 || newValue==2 )
	{
		        
				IG.getFieldById('your_field').required(true);
				
	}

Hi,

Thank you for your reply.

Are you meaning to add a new resource (SCRIPT) and perform this when the form is loaded as a Custom Script?

I was looking for something in runtime. So if you click on a form field and then on the side bar you will see the 'pencil' icon on 'Required' attribute that allow you to build a javascript but :

Thanks.

Hi,

I used it as a resource, indeed. and not in the required-configuration field.

The script will be loaded with the form (use the form:ready event for this) but because of the  "subscribe" it will listen to changes in your third field.

IG.vent.on('form:ready', function(form){
    IG.getFieldById('your_third_field').value.subscribe(function(newValue){
        if(newValue==1){ 
            IG.getFieldById('your_field').required(true);
        } 
    });
})

  But as I said, I am starting in a week to test all my workflows with GMSC 2018, so something might have changed in the API, that I haven't realized yet.
