Add link to view data if no matching record

Question

I have a view that shows taxonomy terms with a relationship to show nodes that have a term reference to that term (relationship not required, aka LEFT JOIN).

For terms that don't have a matching node I would like to show an "add content" link.

The usual "no results" behavior doesn't seem work in this situation. What's the trick?

Views PHP to the rescue:

<?php
if (is_null($row->nid)){
    print '<a href=node/add/mytype?edit[field_mytype][und]='.$row->tid.'>add node for this term</a>';
}
?>

I can even pass the tid through the URL and have it prepopulated on the form (using prepopulate).
