if im displaying pages with data from a database eg
on that page i would like to have a previous and next link that would
take it to id 41 and 39 respectively, the only problem being what if 39
or 41 was empty? then i would want the link to be id=42 or id=38.. is
the best way to do this just loop through the id's until it finds a
entry that isnt empty? or is there any functions for this?
