what the highlight does is create dynamically a new layer and add all
the features with the id's from the queried layer to this new layer. For
polygon layers it uses a LINE highlight layer, but you can easily change
this in map.php in function 'pmap_addResultLayer' by uncommenting
##$newResLayer->set("type", $qlayType);
and commenting out the 4 lines before.
This dynamic highlight layer has to be created/added all the time the
map is created/refreshed.
So after adding the resultlayers to the session you just need to refresh
the map. The map creation in map.php looks if it finds the session var
resultlayers (or the passed var via GET) and then adds these features in
a new dynamic layer to the map. This is done for all further map
creations until the session var is unset.
just use a javascript function to initiate the map refresh like
function refreshMap() {
showloading();
var mapurl = map.phtml?'+SID+'&zoom_type=zoompoint';
parent.mapFrame.location = mapurl;
}
to remove the resululayers via javascript modify the 2nd line to
var mapurl = 'map.phtml?'+SID+'&zoom_type=zoompoint&resultlayer=remove';
