Unlike the tutorial example HelloWorlds (http://processwire.com/docs/tutorials/hello-worlds/) about the planets Earth and Jupiter. Is there a way to pass data to a Processwire page coming from 1) MySQL database or 2) Another Processwire page? That way I can have a database table of planets and just create one or two pages. One page if I had a dropdown of planets then output planet data on same page when a planet is chosen from the dropdown. Maybe 2 pages if I implement a holder/page pattern where the holderpage will have links of planets, and once a planet link is clicked, fetch planet data from the database for info then output fetch data to a detail page?
