[maplab-users] Where/How do session vars get saved in gmf_apps?

[Paul Spencer]

Steve, gmapfactory applications do not use php sessions, so it isn't 
suprising that you can't find this :)  They use a MapSession object to 
manage map state.  The code for this is found in 
common/wrapper/map_session.php.  It contains a base class (MapSession) 
and two concrete classes MapSession_R and MapSession_RW (for ReadOnly 
and ReadWrite).  The difference between them is how the map state is 
maintained.  In both cases, the MapSession instance returns a state key 
from the saveState method that can be used on a subsequent page to 
restore the mapfile to its previous state.  GMapFactory applications use 
MapSession_R and the state key ends up being a set of URL parameters 
that are parsed on the next page by the restoreState method.  If you 
really want to, you can modify the saveState and restoreState functions 
in MapSession_R.  However, I would recommend that you either add session 
support to your gmapfactory app or pass the info on the URL and modify 
drawmap.php to get it.
