[mapserver-users] Mapserver 7.0.5, PostGIS and Query Errors

[James Colannino]

I've done some more digging, and I've realized we're using PHP Mapscript to
further configure the map tiles that are coming back.

I'm using the mapfile to generate a map object in PHP using:

$map = ms_newMapObj(mapfile_filename);

I then get the layer using:

$map->getLayer(0);

Finally, I set filters on the layer like this:

$layer->setFilter(...);

The filters being passed are native filters, and I see from the
documentation that behavior regarding native filters has changed. I think
this might be related to my problem. Does anyone know if the setFilter
function accepts native filters as of Mapserver 7, and if not, if there's
an equivalent function that does? I couldn't find it when referring to the
Mapscript API.

Thank you so much!
