the easiest would be to just extract the feature extent (I guess you are using PostGIS as you mention a database) via PG functions of PHP and the spatial functions of Postgis. And then create the extent string and pass it via the URL and the 'me' key.
This takes probably 15 minutes, trying to understand the (s)query.php logic will take some days ;-) For pmapper 1 and shapefiles one could use another method, mentioned in the documentation at the end. armin Richard Bourque wrote: > Hi everyone, > > I am trying to make a call to pmapper that will bring up the map > already zoomed in at a specified element in the database.
