I bugged Armin a lot and he has always been very helpful. I'd be happy to
help out with some contributions.
Here is a good way to do the hilighting so that you don't have to add all of
the lines to each shapes. It scales better and works much much faster. It
works best with POSTGIS layers, but thats mostly what I deal with. My users
rarely ever query shape file based layers.
I based this off of a VERY modified 1.0.8 p.mapper. In incphp/map.php
replace pmap_checkResultLayers function and the the highlighting function
that follows it with this. On the older p.mapper versions you should be
able to just drop it in.
All it does is create a dynamic layer by cloning the one that will be
highlighted. Then it writes it over the one being queried. This works well
if you need to have a big query limit set or you have lots of features in a
layer.
