I'm sorry guys, this should be basic querying and I ought to have figured it
out, but I'm stuck. I'm trying to get a basic query of a shapefile-based
layer. For testing, I hard-coded some parameters to see if it will work. But
try as I might, my searches return 0 results even though I know results should
be returned.
I'm on MapServer 6.0.2. Here is the code:
$map = ms_newMapObj('/ms4w/apps/geoparcels/maps/parcels.map');
$layer = $map->getLayerByName("parcels");
$expression = "'[TOWN]' == 'Acton'";
//perform query
$layer->queryByAttributes("TOWN",$expression,MS_MULTIPLE);
if($layer->getNumResults() > 0) {
echo "results found";
}
else{
echo "no results found";
}
-What am I doing wrong?
