Email Script - Hide Fields in Email Notification

[WP2]

Hello All,

I have the below email script however, i will like to hide these fields (e.g Description etc) in the email notification when no value is provided. In the email notification, they should be hidden only when no value is provided. What is the logic to achieve this for the below scripts?

1. template.print('<div>Description: ' + (current.sysapproval.variables.description ? current.sysapproval.variables.description.getDisplayValue().toString() : "" )+ '</div><div>&nbsp;</div>');

2. template.print("Summary:\n");
var gr = new GlideRecord("sc_req_item");
gr.addQuery("request", current.sysapproval);
gr.query();
while(gr.next()) {
template.print(gr.number + ": " + gr.quantity + " X " + gr.cat_item.getDisplayValue() + " at " + gr.cat_item.price.getDisplayValue() + " each \n");
}

3. Comments: ${sysapproval.comments}

Thank you.

I'm not very experienced in mail-scripts in particular, but have you tried using an if statement to check if the value exists?

I'm not quite sure what your script is doing so forgive me if I butchered it.. but I imagine your answer looking something like this:

if(current.sysapproval.variables.description.toString() != ''){
template.print('<div>Description: ' + (current.sysapproval.variables.description ? current.sysapproval.variables.description.getDisplayValue().toString() : "" )+ '</div><div>&nbsp;</div>');
}

Thanks for your help.

I tried but same result in the notification (see below)

Ah okay, so what I think is going on here is that your template.print() function isn't working properly.

Try this:

if(current.sysapproval.variables.description.toString() != ''){
template.print('<div>Description: ' + current.sysapproval.variables.description.toString() + '</div><div>&nbsp;</div>');
}

Otherwise it might be that even though the description is blank the if statement is evaluating to true.  Likely because the variable is returning NULL which isn't equal to an empty string.  In that case replace the condition for the if statement with if(current.sysapproval.variables.description).

Try this

if (current.sysapproval.variables.description.getDisplayValue()!='')

template.print('<div>Description: ' + (current.sysapproval.variables.description ? current.sysapproval.variables.description.getDisplayValue().toString() : "" )+ '</div><div>&nbsp;</div>');
