[wp-hackers] Looping through categories

[Ryan Bilesky]

Well not sure if this absolutely the best way to do this but what I would do
is this

have a for each loop to go though categories, inside that set a Boolean to
false then do a for each with the posts that are in that category, check the
meta data and if it matches what you need set the Boolean true and exit that
loop then you can build add to the output if the Boolean is set to true.
