           Summary: Setting filter in MapOverlay
           Product: CartoWeb
           Version: unspecified
          Platform: PC
        OS/Version: All
            Status: NEW
          Severity: enhancement
          Priority: P4
         Component: Plugins
        AssignedTo: cartoweb-dev at lists.maptools.org
        ReportedBy: ml.dje at geocontent.de


the Cartoweb documentation of the MapOverlay plugin suggests to use the data
field to filter data. This seems to be a little restrictive, because it does not
work for all layer types. Therefore, I would suggest to handle FILTER and
FILTERITEM separately.
I created a patch that adds the necessary fields and function calls to the
common and server part of the MapOverlay plugin.

The example in the documentation would change to

$layer->filter = "farm_id = {$farmId}"

So far, I only did initial testing with PostGIS layers.

Let me know, if you think this might be a meaningfull extention.
