Record Goal without recording pageview?

Hi, new to Piwik. Thank you for great script :)

I have some popups that I want to record goals for. They are really not pageviews, and I don't want to count them as such. I am using the php interface for piwik. How do I record those as goals, but making sure the page views are not incremented. I am using $t->doTrackGoal but it seems to also increment pageviews.
