Not displaying the category when no product in it

Hello,

I can not find my answer anywhere.

Like I wrote in the subject I don't want to display the category name(in the category box) if there is no product in it. I would like to know if something exists for it. I insert my products with with a php script and I would like to have something "automatic" for the category displaying.

I hope you understand what I mean.
Thanks

There is not a setting for this. The Categories with no Products Status setting in Configuration > Layout Settings determines whether to display the count if it is 0; this information could be captured and used to turn off the whole category name display. Moderate PHP coding skill required.

Yes but I don't know how to do it. I guess it is in the file /includes/templates/template_default/sideboxes/tpl_categories.php
but I am not sure..

Someone has any idea?
thanks a lot
