Often, in an email template, you want to print something like:
Division: Finance
Location: Austin
Comments: These are comments important to your knowledge of what just happened....
If the comments variable happens to be empty, you get this:
Division: Finance
Location: Austin
Comments: $comments
Many users will want to print nothing for an empty variable. In this case, you can do the following:
Since we use Apache Velocity (http://velocity.apache.org/) to render our email templates, you can use any Velocity feature in your email templates.
In Velocity, you can add an If statement around your comments field, so that an empty comments variable will result in nothing being printed out like so:
#if ($comments)
Comments: $comments
#end
Now, the results would look like so:
Division: Finance
Location: Austin

Note: As of Identity IQ 6.1, we use Apache Velocity Version 1.5.
