Check if tree branch has data
I have a menu tree in a mysql database which I can display easily by a recursive php function
INSERT INTO `car_nav` (`rowid`,`parent`,`name`) VALUES
INSERT INTO `car_data` (`navid`,`details`) VALUES
(5,'this car has...'),
(5,'a luxury model for...'),
(6,'another car for...'),
Is there a way in PHP to show only the branches who end in an entry from the car_data DB and leave out those who are blind?
In above example all branches that origin from VW would be hidden, as there are no models assigned.
