The problem is, I don't get the expected results. I very rarely get any
features returned from the first layer, and I always get results from the
second layer, even if there isn't a feature at the click point. I have
verified that coordinates being calculated are correct. Both layers have
templates defined in the mapfile.
When I click directly on a line from the first layer in the map, with a buffer
of 25.0, I should get the feature I have clicked on, but I always get the
underlying polygon. When I click on a gap between polygons with a buffer of 0,
I should get no results, but I always get one of the polygons close by.
Could part of the problem is that you set the buffer to 0? That means
that the buffer defaults to whatever tolerance you have set in the map
file. From the phpmapscript reference:
"Passing buffer <=0 defaults to tolerances set in the map file (in pixels)"
