[Mapserver-users] PHP/MapScript question: How to return values when map is clicked?

[Krung Saengpole]

I'm not sure with getLayerByName.  Try quote name in map file. eg.
LAYER
  NAME "state"
  ....

getLayer() take parameter as
$layer=$myMap->getLayer(layer_index);

Your warning stated that it couldn't find the point you clicked. You can avoid this message by prefixing the function with '@' (PHP aspect) as
@$myMap->queryByPoint(...);

What is your layer's type in map file?  It should be POLYGON if you want to click inside its boundary.
