[Cartoweb-users] Web Map Context and Cartoweb

Hi Mathieu

There is no existing plugin (as far as i know) do to that. 
After some discussion it seems changing the mapfile during cartoweb execution is at the moment impossible. Everything is based on the initial mapfile. You would need to bypass cartoweb normal flow of execution by forcing a reset after the mapfile replacement.

Using mapscript, make your function to generate the map from context, then write it via the ->save methode of the map object (maybe). Then force a reset.
This is quite theorical and I cant guaranty success.

  Subject: [Cartoweb-users] Web Map Context and Cartoweb

  Hi list,


  I would like to load a context in Cartoweb using the loadMapContext function, 

  As it's possible to load a context with mapserver: Map Context Support Through CGI (http://mapserver.gis.umn.edu/docs/howto/mapcontext).


  The aim is to generate a map file using my context file (mycontext.xml). Then, the map file could be read by cartoweb as a common map file.

  I know the function to convert my context in map file but the problem is: 

  - Do I need to write a new plugin to generate my map file? 

  - Can I use an existing plugin and which files do I need to modify?


  Please, any help would be greatly appreciated.
