[Cartoweb-users] Changing selected layers in code

[Alessandro Muzzetta]

Hello,

is it possible to change the layers that are activated by default directly
in code instead of having to change the layers.ini file?

I have several dozen layers of which only two will be active at any given
time.  Deciding which two layers will be displayed is going to be decided by
an algorithm written in php, not by the user.  At every page refresh, the
algorithm, based on several parameters, will set just two layers to
selected.
Is there a way to do this within Cartoweb in php?

The only ugly solution I have thought of so far is to overwrite the
layers.ini file with a new one and having the pertinent layers marked as
selected.  However, aside being ugly, this runs into problems with caching.

Any help would be appreciated.

Thanks
